This is though the card differed from the matching cards in respect of both shape and number erectile dysfunction on prozac trusted zudena 100 mg. Despite this instruction erectile dysfunction treatment injection buy 100mg zudena with amex, some frontal patients will continue to best male erectile dysfunction pills over the counter cheap zudena amex sort according to impotence due to diabetes order 100 mg zudena otc the obsolete rule, showing an inability to think exibly and change behaviour to adapt to the “new situation”. The cards could be sorted according to several criteria including shape, shading, category of word written on each, and so on. First, they were not very good at sorting the cards into meaningful groups at all, and second, even if they could sort as per the instructions, they struggled to describe the actual rule they were using. Other tests that assess conceptual thinking are the Brixton and Hayling tests (Burgess & Shallice, 1997). In the Brixton test, participants must predict which of an array of numbered circles will be lled in on the next trial. This is determined by one of several simple rules and periodically the relevant rule is changed. Frontal patients make more errors on this task than controls or patients with posterior lesions (Shallice & Burgess, 1996). The Hayling task consists of two sets of 15 sentences, each with the last word missing. In the rst task (Hayling A) participants must complete the sentence as quickly as Domains of executive dysfunction 293 possible with an appropriate word. In the second task (Hayling B) participants must complete the sentence with any inappropriate word. This second condition is much more di cult, requiring participants to inhibit a cued prepotent response and to generate an entirely novel response. Patients with frontal damage are impaired on both Haylings A and B, but it is suggested that di erent fundamental processes underpin the impairments (Shallice & Burgess, 1996) with Hayling B capturing important aspects of executive function. One component is sequencing: we must generate a sequential plan of action incorporating various subcomponents in an appropriate order. Second, successful behaviour requires self-monitoring, essentially the process of checking that we are on track to achieve the desired result. Sequential planning Research suggests that individuals with frontal lobe damage struggle with tasks that, for successful completion, must be broken down into a series of subroutines to be completed in the right order. Problems may arise because of composite di culties in sequential planning, memory, self-monitoring, and of course not losing sight of the overall goal (see Box 11. The kettle must be lled, the tea should go in the pot, milk in the cups, and so on. The point of this example is to illustrate the range of psychological skills implicated in even this simple task: Our tea-maker has to have a strategy: they must sequence different elements of the task in the correct order; they must remember what has already been done, and what yet needs to be done; and nally they must be able to adapt the task to changing circumstances (if needs be) to ful l the overall goal. A study by Milner (1982) neatly illustrates the particular di culty some frontal patients have in distinguishing between more and less recent events. On recognition trials, the respondent had to decide which of the two objects had appeared in the preceding sequence (one had appeared but the other was new). In recency trials, the respondent had to decide which of the two objects had appeared most recently. The recognition rate of frontal patients was comparable with that of control participants, but recency judgements were signi cantly impaired. In other words, frontal patients could not remember the order in which the material was viewed. Incidentally, there was also a laterality e ect evident in this study giving rise to a double dissociation. Patients with left frontal damage fared worse with verbal material than with drawings, and patients with right frontal damage did worse with drawings than words. The previous study shows that frontal patients struggle to memorise sequences—but do they also struggle in planning sequential actions Respondents were required simply to point to any item in a 3 2 array that they had not pointed to before. The array always contained the same six items, but their location was changed on successive trials. Frontal patients made signi cantly more errors than controls, suggesting a marked impairment in planning of sequential actions. Impaired planning of sequential action is also seen in tasks such as the “Tower of London” puzzle (Shallice, 1982). On each trial the balls are placed in the standard starting position and the participant must move them to a di erent speci ed nishing position in the least possible number of moves. Some trials require only two moves, while others require ten or more to reach the nal con guration. Frontal patients are worse than controls on both simple and complex trials, although the gap widens on complex trials. Even when they do solve the puzzle, it is as if they have stumbled across the answer rather than thinking it through step-by-step (see Figure 11. Self-monitoring When neuropsychologists refer to self-monitoring, they are really talking about the re exive skill of self-inquiry: “How am I getting along with this task From a standard starting position (a) the participant might be asked to rearrange the balls in various ways that require two (b), four (c), or more (d) moves. Patients with dorsolateral prefrontal damage probably struggle on this test because their ability to plan a sequence of actions is compromised. Anecdotally, case reports frequently allude to the frontal patient’s inability to “keep on track” during prolonged tasks. When asked to copy one of several drawings on a page, they may start accurately, but then integrate material from one or more of the other drawings into their own. In a classic “real-life” study of the derailment that is seen in the goal-oriented behaviour of frontal patients, Shallice and Burgess (1991) set three patients a set of relatively simple tasks to complete. These included shopping for certain items, nding out some information about four queries (the price of a pack of tomatoes, etc. This was speci cally not a memory test and respondents had a list of the tasks and instructions to follow. In one case an item could not be purchased because the shop did not stock the individual’s favourite brand; in another, items were selected but not paid for; or, worse still, an entire com ponent of the assignment was ignored. This is a particularly good illustration of the problems frontal patients have in achieving goals. They start with the best intentions, but are easily distracted, and are unable to get back on track because of an apparent lack of awareness about being blown o course. However, executive functions are also thought to be called on in situations where people are required to perform more than one task, thus maintaining multiple goals. Typical examples of this are task switching (where people move between distinct tasks) and multi-tasking (where they attempt to carry out more than one task at the same time. If I sit at my desk writing an email and the phone rings, I stop writing and pick up the phone. I must switch task from writing to one person to talking to another and it may take a moment to adjust to the change. This phenomenon can be studied in an experi mental setting by using two (or more) simple tasks and switching between trials of each task. Rogers and Monsell (1995) devised a task where participants looked at a grid of four squares on a computer screen. When the pair was at the top participants had to decide if the letter was a vowel or consonant, and when the pair was at the bottom they had to decide if the number was odd or even. On two of the four trials participants were doing the same task as the last trial; on the other two they were switching to a di erent task. On trials where participants switched, they made more errors and their reaction times were signi cantly longer. There are several interesting characteristics of the switch cost which tell us more about the nature of task switching (Monsell 2003). First, the switch cost is reduced but not eliminated if people are given a chance to prepare for the switch. Second, although the switch trials are particularly slowed, performance overall is slower in a task-switching block of trials than in a single-task block, suggesting longer-term as well as transient e ects of switching. Third, switch costs are most pronounced when participants switch from a hard to an easy task, as compared with an easy to hard switch. These observations have led theorists to suggest a number of mechanisms that are important in task switching.
The research has fairly consistent support for the following ideas: I Pupils do learn in different ways to erectile dysfunction drugs from canada trusted zudena 100 mg each other erectile dysfunction blood pressure medications side effects order cheap zudena online. I Pupil performance in different subject areas is related to impotence existing at the time of the marriage buy 100mg zudena overnight delivery how individuals learn erectile dysfunction age 30 buy zudena us. I When pupils are taught with approaches and resources that complement their particular learning styles, their achievement is significantly increased. The third of these points has importance for teachers if they are to develop approaches to teaching all pupils that will ensure that the greatest number of learners in their classes benefit from their teaching. Another interesting but, in the light of what has gone before, possibly quite obvious pointer from research is that children are far more likely to complete their homework if ‘its design takes into consideration students’ learning styles and study habits’ (Dunn et al. By learning about the learning style preferences of learners, teachers put themselves in a far stronger position when they come to the task of planning learning approaches and classroom activities that are most likely to take advantage of pupils’ individual learning styles, which will in turn help them to achieve their learning goals.

Problems can arise for teachers who try to explain things in a way that they consider everyone can understand, when some of their pupils have difficulty in making sense of what they are being taught. From what we have seen, a pupil of a different temperament, whose mind is set in a different way from his or her teacher’s – in short, with different learning style – is likely to have the greatest difficulty. It is highly likely to be of great value if both teachers and pupils can have awareness of the potential problems that differences in learning style and preference may lead to. That is, they should (in particular the teacher should) be fully aware that we all learn in different ways, behave in different ways and go about our lives in different ways. Parents too can benefit from knowledge of these differences, as it can impact on the approaches they might take when supporting their children’s school work at home. From the point of view of the teacher then, the important point about learning styles is not to be concerned with how many styles are listed, nor how they might be labelled, but to raise awareness in both teacher and learner that everyone is likely to learn in a different way, and that different learning styles present needs which must be met if teaching is to be effective and learning to take place. According to Bandler and Grinder (1979), 70 per cent of learners will be able to cope however a lesson is presented; 10 per cent will be unable to learn whatever method is employed, for reasons largely unrelated to learning style; but the remainder will only be able to learn in a visual, auditory or kinaesthetic way. It should perhaps be the view of teachers that 70 per cent is not enough and that some action needs to be taken in order to increase this figure. The answer is ‘both’; and the concept to 5 think of is that of learning communities. All (institutional) learning can be thought of from a wholly 6 social perspective, as one of the learner joining a community, and becoming enculturated. From that 7 point of view, the learner needs to do the adapting, and the more they do so, the more they gain 8 access to that subculture and its knowledge. However, since it is the 12 prime role of a teacher to facilitate and encourage learning in all of their pupils, it is fairly clear 13 that the real responsibility to accommodate lies with the teacher. Naturally though, some 14 accommodating is also required on the part of the learner. An example of 17 how to teach to all types, which can also be described as ‘appealing to a wide range of learning 18 styles’, based on, for example, the Felder-Silverman Model, might look something like this: 19 I For the sensing/intuitive continuum: balance concrete information, such as facts and 20 experimental results, with conceptual information like theories and models and ideas. Encourage both logical, 2 linear thought patterns and the wider, sometimes referred to as ‘lateral’, patterns of thought. The lists refer to learning preferences and suggest particular 5 activities which are likely to satisfy all of, or at least as many of the different preferences that are 6 likely to be encountered. While teachers have a view to providing appropriate learning activities for a range of different learning styles, they must also have a clear grip on the fact that success in our current educational climate depends heavily upon reading and writing. Identifying learning styles We have seen that it is helpful for teachers to consider the learning styles of their pupils and for them to incorporate what they discover into their approach to planning – at an individual level sometimes. There are formal tests and quizzes designed to identify learning styles and some schools make use of them. Naturally, each learning style ‘quiz’ or inventory will be designed to categorise learners according to the theoretical position on learning styles taken by its creators. It is possible to find formal ways of identifying learning styles to suit the preferred descriptions of learning styles available, some of which we have considered earlier. There are also similar tests or quizzes available to help in the identification of multiple intelligence strengths and preferences. Some schools or individual teachers like to encourage their pupils to consider their particular learning styles and some of the online quizzes are helpful at this level. In some cases, teachers do not want to go as far as formally examining the learning styles of a class, but would still like insight into an individual’s style in order to be able to understand better how they are likely to function in learning situations. It appears that, at a simple level, it is possible to pick up on some visual cues which give an idea of an individual’s style. Put simply, and as we saw earlier, visual learners tend to look up (for a mental picture perhaps), auditory learners tend to look to the side and kinaesthetic learners tend to look down. The reasons for this are not given in any of the easily available sources, but it does seem, as a rule of thumb, to be useful. There is a possible drawback to helping children to identify their particular learning style: if a child is given a particular learning style label, it is possible that they will centre their learning on this one approach to learning and even refuse to work in other modes. When introducing the idea of learning styles to children, it is probably helpful to stress the importance of being able to work and learn in different ways at different times and for different purposes. A case – even a strong case – for encouraging children to develop ways of learning that do not come easily to them can be made. Summary Individual learners have preferred ways of working, thinking and learning. If an individual’s preferred approach to learning tasks is ignored in the ways that a teacher expects them to work, there is a distinct possibility that their learning will not progress as efficiently and effectively as it might. One description com 1 monly used to help teachers understand differences in a practical and immediate way is the 2 ‘visual/auditory/kinaesthetic’. It is likely that one-third of any given class will have a preference 3 for learning which is undertaken in one of these divisions. This means that teachers should be 4 aware of and take into account the fact that some of their pupils will find it difficult to make 5 headway with their learning if at least some of it is not presented in an appropriate format for 6 them. We have discussed the links 16 between multiple intelligences and learning styles, and it is reasonable to repeat the points from 17 Chapter 4 here: 18 19 I Be aware that individuals have different strengths and are likely to perform very differently 20 according to the nature of the style of the tasks with which they are presented. There will also be a brief consideration of how best to deal with some of the manifestations of special needs in an attempt to, maximise the learning of those children who are affected. An important consideration for a book of this nature is the potential which learners have for difficulties or setbacks with their learning. What we might call normal, that is following a route through learning and intellectual development which might be wholly expected, does not apply to all learners. Indeed the very notion of normal might be scoffed at since all learners have unique attributes, strengths and weaknesses, but it is possible to pencil in a simple divide between relatively straightforward learning progression, and learning which is problematic and dogged by difficulty of one sort or another. In reality a dividing line is not a useful tool since the range of learning ability is probably best represented by a continuum from extremely difficult to non-problematic.
Trichomonas can survive on wet towels and other surfaces and thus can be nonsexually transmitted erectile dysfunction neurological causes buy zudena from india. Vaginal exam may reveal a frothy erectile dysfunction 70 year olds buy zudena 100mg cheap, malodorous yellow-green discharge with vulvar irritation zinc causes erectile dysfunction 100 mg zudena amex. A wet smear preparation that is promptly reviewed may reveal the flagellated erectile dysfunction at the age of 25 purchase discount zudena line, mobile protozoon with a sensitivity of approximately 70%. Point-of-care tests are available and have higher sensitivity than vaginal examination, but false-positives can occur. Culture should be obtained in women who have clinical suspicion for trichomonas when microscopic evaluation is negative. Treatment consists of one 2-g dose of either metronidazole or tinidazole by mouth. While trichomoniasis has been associated with premature rupture of membranes and premature birth, treatment of the infection has not been found to reduce these risks and may in fact increase the risk of premature birth. Most organisms are susceptible to metronidazole but low-level resistance has been documented for 2% to 5% of vaginal trichomonas. Sexual partners must be treated and the patients should be instructed to avoid intercourse until the treatment is completed and symptoms have resolved. These are often non-albicans species and are most often found in immunocompromised women, uncontrolled diabetics, or pregnant women. The signs and symptoms include pruritus, vulvar fissures, or excoriations, vaginal irritation, external dysuria, erythema, and edema. Maintenance therapy with 150 mg of fluconazole or clotrimazole 200 mg twice a week or 500 mg once a week is recommended.

The primary pathogens of mucopurulent cervicitis are the two sexually transmitted organisms Chlamydia trachomatis and Neisseria gonorrhoeae. Chlamydia Chlamydia trachomatis is the most frequently reported sexually transmitted bacterial disease in the United States. Risk factors include age <25, low socioeconomic status, multiple sex partners, and unmarried status. Patients with Chlamydia may complain of abnormal vaginal discharge, burning with urination, spotting, or postcoital bleeding. Cell culture for chlamydia infection has a high false negative rate, and is not widely available. Treatment for coinfection with gonorrhea is recommended if local prevalence is >5%. Detection of Chlamydia trachomatis and Neisseria gonorrhoeae by enzyme immunoassay, culture, and three nucleic acid amplification tests. Laboratory testing for Neisseria gonorrhoeae by recently introduced nonculture tests: a performance review with clinical and public health considerations. Gonorrhea Risk factors for gonorrhea are essentially the same as those for Chlamydia cervicitis. Similar to chlamydial infections, 50% of patients with gonococcal cerviciti s are asymptomatic. When present, symptoms include vaginal discharge, dysuria, or abnormal uterine bleeding. Culture is the most widely available option for detection in the nongenital sites and is used when antibiotic sensitivity testing is. Due to increasing resistance, fluoroquinolones are no longer recommended for the treatment of N. Treatment of sexual partners and education is important in reducing the rate of recurrent infections. Other complaints are variable, including vaginal discharge, dyspareunia, abnormal bleeding, right upper quadrant pain, fever and chills, nausea, and dysuria. Additional criteria for diagnosis, which increase specificity Oral temperature >101 °F (>38. Many patients can be successfully treated as outpatients, and early ambulatory treatment should be the initial therapeutic approach. Chronic pelvic pain and dyspareunia have also been reported and are associated with the presence of adhesive disease and the number of episodes. This is particularly important when gonorrhea is detected at mucosal sites by nonculture tests. Fluoroquinolones may be an alternative treatment option if antimicrobial susceptibility can be documented by culture. Endometritis is caused by the ascension of pathogens from the cervix to the endometrium. Chronic endometritis is often linked to common bacteria such as streptococci, staphylococci, and Escherichia coli. Postcoital bleeding, menorrhagia, and a dull, constant lower abdominal pain are other complaints. The diagnosis of chronic endometritis is established by endometrial biopsy and culture. The classic histologic findings of chronic endometritis are an inflammatory reaction of. A diffuse pattern of inflammatory infiltrates of lymphocytes and plasma cells throughout the endometrial stroma or even stromal necrosis is associated with severe cases of endometritis. Women who do not respond to oral therapy within 72 hr should be reevaluated to confirm the diagnosis and should be administered parenteral therapy on either an outpatient or in-patient basis. These pregnancies tend to be recognized at an earlier stage due to the close monitoring in these patients. Ninety-seven percent of ectopic pregnancies are implanted within the fallopian tube, although implantation can occur within the abdomen, cervix, ovary, or uterine cornua. Hormonal parameters can vary depending on the assay technique and reference standard used. The discriminatory threshold for sonographic detection of an intrauterine gestational sac must be established by each institution. Pain is initially intermittent and later becomes constant as vascular supply is compromised. If unstable, may have signs of hypovolemic shock, including tachycardia, hypotension, and confusion. Abdominal exam may have signs consistent with peritonitis, including guarding, rigidity, or rebound tenderness. Up to 15% of women may complain of shoulder pain, secondary to diaphragmatic irritation from hemoperitoneum. After acute hemorrhage, initial readings may be at first unchanged or only slightly decreased; a subsequent decline represents restoration of depleted blood volume by hemodilution. Progesterone A normal intrauterine pregnancy should be associated with a serum progesterone value of 25 ng/mL or greater. Of limited utility, as many patients will have serum progesterone levels between 10 and 20 ng/mL. On ultrasound examination, the diagnosis is suggested by visualization of both an ectopic and an intrauterine pregnancy or the presence of echogenic fluid in the culde-sac in the presence of an intrauterine pregnancy. Caution is advised with interpreting this method because a normal corpus luteum may also demonstrate. In most cases, two separate structures will be visualized: the ovary and the affected fallopian tube. Ten percent of ectopic pregnancies have a pseudosac in the uterus that lacks the “double decidual” sign of an intrauterine pregnancy. Patients in shock or with a surgical abdomen should be resuscitated with intravenous fluids, using two large-bore intravenous cannulas, have an indwelling catheter placed to monitor urine output, and be taken to the operating room as soon as possible (see Chapter 3). Treatment side effects Perhaps the most significant side effect is abdominal pain that arises 2 to 3 days after treatment, presumably from the cytotoxic effect of the drug causing tubal abortion. This pain may complicate the diagnosis of ruptured ectopic and require hospital admission for close observation. Benefits of a single dose include decreased cost, better side-effect profile, improved patient compliance, and no need for leucovorin rescue treatment. Treatment failure is generally defined as a need for subsequent surgical intervention.

Conclusions Neurodevelopmental disorders may occur in association with alterations in all aspects of the visual system. These vision issues can then have severe detrimental effects on the overall development of the child with decreased social, emotional, and communication skills in addition to the educational impact. While an all encompass ing review of vision impairment in children with neurodevelopmental disabilities is daunting in scope, the varied causes of decreased vision in children with neurode velopmental disabilities have been discussed. As well the dif culties in screening and evaluating these patients are obvious; nevertheless the need to do so is crucial to their well-being. New tools for assessment of vision which are easy and effective need to be developed for use in this population. Screening programs in clinics or residential settings have been shown to be effective. A study among residents at a facility in Scotland demonstrated that prior to initiation of a comprehensive screening, only 11% of patients had been offered vision assessment in the previous 5 years. Other than pro foundly impaired patients, an assessment of vision using the variety of methods discussed earlier was achieved. Resources now are becoming more available in the developed world for persons with decreased vision. Vision rehabilitation serves are best provided by a multidisciplinary team which may include the primary care physician, ophthalmologist, optometrist, orthoptist, social worker, nurses, rehabilitation therapists or counselors, and orientation and mobility specialists. Resources such as Lighthouse International, Prevent Blindness America, or the Helen Keller Foundation can provide resources such as online materials or 18 Vision Impairment 295 support groups of national or local nature. Research must continue to provide further detailed information on epidemiologic data in the population with intellectual disability. Checklists for caretakers to assess vision or questionnaires to assist in assessing vision need to be developed for this population and schedules for effective and screening need to be implemented. The goal is to help all children with or without developmental disabilities to maximize their potential and enjoy a fully active life.

Chapter 19 Impact of Neurodevelopmental Disorders on Hearing in Children and Adolescents Bharti Katbamna and Teresa Crumpton Abstract Recent advances in maternal–fetal medicine and neonatology have led to unprecedented increase in the survival of severely preterm babies and babies with severe neurodevelopmental disabilities. These babies typically present with multi ple neurosensory impairments and pose a signi cant challenge to neurodiagnosis and intervention. This review will describe some common neurodevelopmental dis orders that impact the auditory system and present case studies to highlight the current technologies available to diagnose and treat the hearing problems. Data accumulated over the last 20 years clearly indicate that children identi ed and treated appropriately for hearing impairment before 6 months of age catch up with their normal hearing peers by 5 years of age and demonstrate essentially normal speech, language, and hearing development [3–5]. When multiple neurosen sory systems are involved, however, the success of habilitating pediatric patients is highly dependent on multidisciplinary intervention. Moreover, due to overlap ping and associative problems, habilitation in one area often produces changes in B. Crumpton other areas; for example, multisensory (auditory–visual–proprioceptive) integration therapy may augment auditory cognition along with visual cognition and improve communicative skills of patients with neurodevelopmental disorders, and improve ment in communicative skills may in turn help visual cognition. Thus, intervention in such cases may be most successful with multidisciplinary involvement. Moreover, hearing loss may uctuate over time and may be accompanied with poor speech listening abilities, especially in the presence of noise . In some cases, uctuating hearing loss may be precipitated by increase in body temperature (one case report linked it to a novel mutation of the otoferlin gene ), whereas in others no apparent causal relationship has been established [9, 10]. Thus, a moderately loud sound stimulus produces contraction of the stapedius mus cle and allows assessment of the integrity of the eighth and seventh cranial nerves, as well as the intermediate regions of the arc. In some instances though, the eighth cranial nerve is reduced or absent, so that both hearing aids and cochlear implants may not be good options. Epidemiology Prevalence estimates vary depending on patient populations examined by various studies. Crumpton of these entities, the ultimate goal of assessment being the ability to differen tially diagnose cochlear, eighth cranial nerve, and central auditory nervous system function both electrophysiologically and behaviorally using time-dependent and time-independent responses. Children diagnosed with hearing loss, but who are otherwise cognitively unimpaired may bene t the most from cochlear implantation. Other non-audiologic evaluation and treatment options include neurodevelopmental assessment to eval uate neurological and developmental status and need for medical management, genetic counseling to assess link to family history, speech reading and cued speech to supplement auditory information and enhance communication skills, sign lan guage when auditory options are limited, speech and language evaluation and therapy to help facilitate speech and language development, family and psycho logical counseling and/or parent support groups to help better understand the limitations and/or successes with communication and other cognitive skills . A comprehensive audiologic evaluation performed over the next month (2–3 months post-conceptional age) showed normal middle ear systems bilaterally as evaluated by 1,000 Hz probe tone tympanometry (see Fig. Moreover, phase reversal of the click stimuli from rarefaction (–) to condensation (+) produced phase inversion of the sinusoidal activity (see Fig. Behavioral sound eld testing conducted at 4–5 months of age showed responses to narrow band noise stimuli at moderate intensity levels in the low frequencies, but not in the high frequencies (see Fig. Note that sound eld testing is conducted in a sound-treated room, where the sound is directed to one of the many loudspeakers placed typically at right angles to the patient directly in front and/or behind the patient. Thus, sound eld testing provides estimates of hearing in the best ear, without reference to the 302 B. At 5–6 months of age the child was tted with a hearing aid and in spite of auditory-verbal and cued speech communication therapy, private speech therapy, special education services from the local school district for speech-language stimu lation, auditory receptive language development continued to be below par for her age during the next several months. The parents could not delineate if the hearing aid provided any true or objective bene t and the patient was referred to a cochlear implant program for an initial consultation. During the next several months, the child’s hearing improved signi cantly; at 14 months of age she reported to the clinic with pressure equalization tubes bilaterally for middle ear infections she suffered during previous months and despite middle ear problems showed speech awareness thresholds at 30 dB and hearing levels in the mild to moderate range in sound eld testing (see Fig. During her entire rst and second year, the child also received multidisciplinary evaluations and was diagnosed with cerebral palsy. She continued to receive speech– language–hearing intervention, along with occupational and physical therapy for her multiple physical disabilities. At 19 months of age she received a cochlear implant in her right ear and a hearing evaluation after activation of the implant showed bor derline normal hearing in sound eld testing (see Fig. A speech–language evaluation 1 year after activation of the implant showed language comprehension and expression at 15–18 months indicating that her performance age exceeded her hearing age. He designed a walker with a ski and taught her to use the skis skillfully; this exercise has not only helped her physical and psychological disabilities immensely, but has spurred her speech–language development. At 4 years of age, the child’s communication shows signi cant progression and her hearing evaluation shows near-normal hearing both with and without the cochlear implant. However, since the rst 6 months of life are critical for speech– language–hearing development, it may often be bene cial to err toward implantation for development of the best communication skills. The child is now 7 years of age and is in a classroom that is integrated with the public school system and continues to receive special education services. Her speech–language skills continue to re ect that her performance is ahead of her hearing age, even though she is lagging behind her peers due to multiple impairments.
