Williams syndrome is a developmental disorder that affects many parts of the body. Williams syndrome. The average linear coefficient, 10, is 1.34 or .9 dB greater for the WSNH group than the estimated value of .43 for the TDNH group. We found that a second-order polynomial or quadratic function best described these data. We conclude with clinical suggestions for strengthening the audiometric evaluation of individuals with WS and with therapy recommendations. and Hahn MS, Kobler JB, Starcher BC, Zeitels SM, Langer R. Quantitative and comparative studies of the vocal fold extracellular matrix. The combination of SSRIs and low doses of antipsychotics to counteract SSRI side effects seems to be the most suitable medication to treat generalized anxiety disorder and related disorders in individuals with Williams syndrome. Valero MC, de Luis O, Cruces J, et al. Elastic fibres. Depressed mood and other psychiatric manifestations of Cushings syndrome: relationship to hormone levels. Hierarchical linear models: Applications and data analysis methods. Finally, even after controlling for middle-ear pathology and medical conditions or ototoxic mediations known to impair middle-ear health, individuals with WS may evidence surprisingly poor cochlear outer hair cell function relative to expectations for their hearing thresholds [Marler et al., 2005; Marler et al., 2008]. Cherniske EM, Carpenter TO, Klaiman C, Young E, Bregman J, Insogna K, Schultz RT, Pober BR. The pure-tone and DPOAE measurements from these 7 Adult participants were not included in the later hearing or DPOAE analyses. They are often more interested in adults, and may struggle with attention to social cues with peers. The parameters of this function have theoretical importance in that the linear coefficient reflects instantaneous rate of change and the quadratic coefficient indicates the acceleration or deceleration in the DPOAE as a function of stimulus level. The Level 1 model is given by. PMID: 1481839 DOI: 10.1002/ajmg.1320440605 Abstract There are few published reports of adults with Williams syndrome (WS). This finding was expected on the basis of previous literature.17 Mr A improved his anxiety state to reach normal values, probably due to his medical treatment. Received 2013 Jan 17; Accepted 2013 Mar 26. We were able to evaluate 12 individuals with WS in the clinic protocol that included bone conduction measures. Schultz, Robert T. There are many physical features and medical challenges which are fairly common to Williams syndrome. These features include a small upturned nose, long philtrum (upper lip length), wide mouth, full lips, small chin, and puffiness around the eyes. The mechanical responses of the cochlea to stimulus changes of low-intensity levels are linear, including those generated by the outer hair cell system. . Haapaniemi JJ. Current diagnostic methods that include tympanometry, pure-tone and speech testing, otoacoustic emissions, and auditory brainstem responses usually provide sufficient differential information to preclude the necessity of subjecting individuals who are significantly hypersensitive to sounds to a test procedure built upon the repeated presentation of high intensity, acoustic reflex stimuli. Mr A did not experience adverse effects in response to the SSRI treatment, apart from 1 occasion when he suffered a psychotic episode, most likely in response to an intramuscular bolus dose of corticosteroids (methylprednisolone 40 mg) administered to control a mild anaphylactic shock of unknown etiology. 1993 Feb 1;45(3):313-9. doi: 10.1002/ajmg.1320450307. Our findings are consistent with earlier smaller-sample studies reporting hearing loss in WS [Cherniske et al., 2004; Gothelf et al., 2006; Marler et al., 2005; Marler et al., 2008]. Epub 2014 Aug 20. We tested 81 individuals with WS aged 5.33 to 59.50 years. Background: Individuals with Williams syndrome, a rare genetic disorder, are characterized by specific medical, cognitive, and behavioral phenotypes and often have high anxiety levels as well as phobia. These data suggest a larger percentage of adults with WS may have middle-ear pathology than the approximately 17% expected in the general adult population [Kim et al., 1993; Rudin et al., 1985]. Our results indicate that hearing loss is very common in WS. Brown, W. Ted Pediatr Cardiol. The iris collarette is usually absent or anomalous. 6. . representative sample of 62 adults with Williams syndrome. An additional demonstration of the integrity of the data is that four individuals seen during the WSA conventions were subsequently seen by independent, licensed audiologists for full audiometric evaluations. Mr A currently reports that his mood has been stabilized. Evaluation of cochlear hearing disorders: Normative distortion product otoacoustic emission measurements. We do know that the elastin deletion causes early aging, and depending on general health and pre-existing conditions, life expectancy may be somewhat lower than in the general population. ), and support from the Ohio State University New Faculty Investigator Award (J.A.M.).

SSRIs as mood stabilizers for bipolar II disorder? the contents by NLM or the National Institutes of Health. Pober BR, Morris CA. Interestingly, impulse control disorder has been described in individuals with Williams syndrome17 (T.R.M., personal observation). The variations of her treatment are summarized in Table 3. Further investigations need to be performed to evaluate whether a loss of cochlear compression as measured by the DPOAE IO might actually precede measurable hearing loss in WS or whether measures of residual compression can be determined [Johannesen and Lopez-Poveda, 2008]. What are the symptoms of Williams syndrome? In: Dallos P, Popper An, Fay RR, editors. Gsdl, Marisa Of the Adult participants for whom bilateral data were obtained, 7 of 32 (22%) had tympanometric measurements for one or both ears falling outside the acceptable range for a healthy Type A tympanogram, indicating abnormal middle ear function (5 with Type Ad tympanograms indicating normal middle ear pressure but high compliance and 2 with Type C tympanograms indicating normal compliance but significant negative pressure). The amplification gain can be as much as 50 to 80 dB, especially for low-to-mid intensity sounds [Ruggero et al., 1997]. This is particularly true for children. PubMed ID: 15534874. Strikingly, very few of the parents were aware that their family member with WS had hearing loss prior to participation in this study. Although the antipsychotic doses of levomepromazine given to normal adults are usually higher (over 100 mg/d), we adjusted our dose range based on the observation of clinical outcomes both to regulate the sleep and to alleviate the irritability and dysphoria. We suggest that the 4000-Hz DPOAE IO be incorporated into the audiological battery of tests for individuals with WS, particularly children who show normal behavioral hearing. To decrease the likelihood of an error resulting from a single-frequency outlier, for each frequency of interest (1500, 2000, 3000, 4000, and 6000 Hz), we averaged the DPOAE level immediately preceding and immediately following the frequency of interest (e.g., DPOAE f2 levels reported for 1500 Hz were derived by averaging the DPOAE f2 levels at 1418 Hz, 1550 Hz and 1687 Hz). Multilingual Aphasia Examination Manual. [Epub ahead of print]. Karmiloff-Smith, Annette These criteria were chosen because DPOAEs are most appropriate for detecting mild to mild-to-moderate hearing loss [Gorga et al., 2005; Gorga et al., 1997] and to further minimize possible detrimental middle ear contributions to DPOAE amplitudes. In the clinic protocol, bone-conduction was used, when necessary, at octave frequencies between 500 and 4000 Hz. The research protocol was approved by the James Madison University Institutional Review Board. FOIA American Academy of Pediatrics Committee on Genetics, 2001, http://frontiersin.org/conferences/individual_abstract_listing.php?conferid=389&pap=1996&ind_abs=1991&q=1994.

Post hoc review of individual 4000-Hz DPOAE IO function data revealed that the lowest intensity for which all participants from both groups had responses 3 dB above the noise floor was at DPOAE f2 levels of 50 dB SPL. The outer hair cells are thought to have a motor capability allowing them to change their shape according to the frequency characteristics of an acoustic stimulus [Bacon, 2004; Holley, 1996]. 2004. Echocardiographic findings in patients with Williams-Beuren syndrome. The main symptom is borderline (intelligence quotient, IQ 70-79) or abnormally low intelligence (IQ < 70). A significant Group Frequency interaction was obtained [F(4,54) = 4.243, p = .005, p2 = .239]. Mr A is unlikely to integrate in the workforce, except in jobs specially designed for him. Otoacoustic emissions are not a direct measure of perceptual hearing sensitivity, but a noninvasive, objective test of the integrity of the cochlear outer hair cells. Features of the Peters' anomaly may be present. It is generally accepted that the outer hair cells play a primary role in modulating cochlear compression [Oxenham and Bacon, 2003; Robles and Ruggero, 2001]. How executive functions are related to intelligence in Williams syndrome. The audiological reports for these individuals indicated that their diagnostic threshold responses were within 5 dB of the responses measured in our convention-protocol environment. sharing sensitive information, make sure youre on a federal The basic premise of AIT is that the individual who is hypersensitive to moderately intense sounds can be conditioned to learn to tolerate them via adaptive training [Miani et al., 2001].

Concurrence of supravalvular aortic stenosis and peripheral pulmonary stenosis in three generations of a family: a form of arterial dysplasia. Williams Syndrome. Once depressive symptoms subsided, lamotrigine treatment was stopped. For these reasons, we have collapsed participant responses across the two protocols and have reported behavioral hearing sensitivity data as minimum response levels (rather than suggesting that all are estimations of hearing threshold). Before People with Williams syndrome also often have advanced language skills, outgoing personalities, and a love for music. Lucertini M, Moleti A, Sisto R. On the detection of early cochlear damage by otoacoustic emission analysis. 2003. Acknowledgements and Rights | Admin | Login. Longitudinal course of anxiety in children and adolescents with Williams syndrome. DPOAEs are of primary importance to the present study as low-amplitude DPOAE levels in individuals with normal hearing sensitivity have also been hypothesized to reveal subclinical noise-induced damage [Lucertini et al., 2002; Marshall et al., 2009; Mills et al., 2007; Sisto et al., 2007; Zheng et al., 1997]. In one other adult (age = 53 yr.) we could not achieve a seal for either ear. In particular, 12 of 14 (85%) individuals with WS who had hearing within normal limits also showed a clear, steep slope to the higher-intensity stimuli in their DPOAE IO functions a strong indication of a loss of cochlear compression and cochlear pathology. Clinica San Juan de Dios and Clinica Nuestra Seora de La Paz, Madrid, Spain (Dr Urgeles and Ms Alonso); Department of Molecular Biology and Center of Molecular Biology Severo Ochoa, Universidad Autnoma de Madrid, Cantoblanco, Madrid, Spain; and Department of Clinical Sciences, Division of Neurology, Experimental Epilepsy Group, Wallenberg Neuroscience Center, Lund University, Lund, Sweden (Dr Ramos-Moreno). Drs Fournier, Krzyzanowska, and Martinez-Serrano report no conflicts of interest related to the subject of this article. Williams syndrome (WS) is characterized by developmental delay, intellectual disability (usually mild), a specific cognitive profile, unique personality characteristics, cardiovascular disease (supravalvar aortic stenosis, peripheral pulmonary stenosis, hypertension), connective tissue abnormalities, growth deficiency, endocrine abnormalities (e. For the School Age group, a response > 20 dB HL at any single frequency in a single ear measurement was considered a fail. For the adult group, any response at a level higher (poorer) than the normative data reported by the International Organization for Standardization [ISO, 1984] for the participants age was considered a fail. This criterion takes into account normal age-related changes in hearing sensitivity [Cruikshank et al., 1998]. Jarrold, Christopher Ms B, a 35-year-old woman, was diagnosed with Williams syndrome at the age of 20 years, with confirmed positive fluorescence in situ hybridization to an elastin gene deletion in chromosome 7. In the clinic protocol, bone-conduction testing was used to further evaluate middle-ear contributions and the presence of air-bone gaps. 1996 Jan;49(1):28-31. Manual for the State-Trait Anxiety Inventory. Hayman-Abello, S. E. Neurogenetic developmental disorders: Variation of manifestation in childhood. The Revised Visual Retention Test. . Milestones such as walking, talking and toilet training are often achieved somewhat later than is considered normal. As adults, they are often shorter . To our knowledge, the present study is the first to describe sub-clinical impairments or previously undetected cochlear damage in children with WS who have otherwise normal middle ear function and behavioral hearing responses. Ms B has hobbies, including playing the piano and attending piano classes. One clinical method of testing outer hair cell function is distortion product otoacoustic emissions (DPOAEs2). Department of Communication Sciences and Disorders, James Madison University; Williams syndrome, genetic hearing loss, noise-induced hearing loss, sensorineural hearing loss, distortion product otoacoustic emissions. National Library of Medicine 1990 Aug-Sep;79(8-9):869-70. Young, Eytan 800.806.1871 Routine otoscopic examination revealed that the tympanic membrane was either wholly or partially visualized in 74/81 participants. This site needs JavaScript to work properly. 70 dB SPL) for participant i. For the last 3 years, Mr A has been maintained with a combination of low-potency sedative antipsychotics (levomepromazine oral drops 21 mg/d) and very low doses of an SSRI (citalopram 10 mg/d), well below the effective doses used for adults, which tend to be in the range of 2060 mg/d. PMC Benton ALHK. In order to assess cochlear compression in the WSNH group, DPOAE IO functions were fit using multilevel modeling [Moskowtiz and Hershberger, 2002; Raudenbush and Bryk, 2002]. Hearing loss is common in school-age individuals with Williams syndrome (WS) and extensive in adults. Teaming up to expand Alzheimers and Down syndrome research, Cognito Therapeutics Initiates Studies in Down Syndrome Associated Alzheimers Disease. Carpenter, Thomas O. Benton A. A large proportion of the participants across both age groups had higher-than-expected minimal response levels, indicating hearing loss [School Age: 20 of 34 (59%), Adult: 21 of 25 (84%)]. Mills DM, Feeney MP, Gates GA. Alternative baseball relies on Americas favorite pastime to help teach life skills to those with intellectual disabilities. Williams syndrome (WS) is a rare genetic disorder that occurs in about 1 in 8,000 births. They are extremely sociable and experience the normal need to connect with others; however people with Williams syndrome often dont process nuanced social cues and this makes it difficult to form lasting relationships. When Ms B first came to the clinic, she was being treated for depression with lamotrigine every 12 hours and gabapentin.

Please enable it to take advantage of the complete set of features! Margolis RH, Heller JW. Osborne LR, Mervis CB. Ranheim EA, Kwan HC, Reya T, et al. Williams syndrome can cause symptoms in different parts of the body, such as the face, heart, and other organs. The DPOAE data strongly suggest that as individuals with WS mature, there is an increasing contribution of cochlear dysfunction to the high-frequency hearing loss found in WS. Moreover, treating anxiety properly in Williams syndrome might allow these patients to develop adequate responses to social stimuli and neuropsychological strategies. Studies of the psychiatric phenotype in adults affected by Williams syndrome or literature on the management of their mental pathologies are lacking. On the existence of an age/threshold/frequency interaction in distortion product otoacoustic emissions. The absence of a significant Group effect in the DPOAE amplitude levels suggests that outer hair cell function in the School Age group was not significantly better than in the Adult group, despite the significantly better hearing sensitivity in the School Age group (see the hearing analyses above). The influence of the cochlear efferent system on chronic acoustic trauma. Hotta Y, Kishishita H, Wakita M, Inagaki Y, Momose T, Kato K. Ocular findings of Williams' syndrome. However, both the confidence interval and the negligible effect size suggest that the Group Ear interaction is not clinically meaningful (see Table I). Examination of Figure 4, which includes both group averages and individual data, suggests that the data for both groups are best described by curvilinear functions with different shapes. How is Williams syndrome diagnosed? Cherniske EM, Carpenter TO, Klaiman C, Young E, Bregman J, Insogna K, Schultz RT, Pober BR. Diagnosis and management of medical problems in adults with Williams-Beuren syndrome. Norbury CF, Bishop DV, Briscoe J. DPOAEs are especially helpful clinically for predicting auditory sensitivity and cochlear health in individuals with hearing thresholds 50 dB HL [Gorga et al., 1997; Gorga et al., 2000] and are useful in corroborating behavioral measures in individuals who have intellectual disabilities [Hild et al., 2008; Neuman et al., 2006]. 2014 May 21;14(1):70. Approximately 95% of individuals with WS have the same set of genes deleted [Bayes et al., 2003]; most of the remaining individuals have additional genes deleted. Insogna, Karl Parents of children with WS, regardless of whether their child currently has a hearing loss, should be educated about methods of protecting their child from exposure to sustained noise (e.g., sustained vacuuming, public events in enclosed arenas, movie theaters, use of personal listening devices such as iPods). Accordingly, the deletion is present at the time of conception. Williams syndrome is caused by the spontaneous deletion of 26-28 genes on chromosome #7. Importantly, it is likely that cochlear pathology is present prior to the onset of hearing loss. Iowa City, IA: University of Iowa; 1976. Multilevel model results for the 4000 kHz DPOAE IO functions. These should be considered . 2006. 2001. The functional obstruction of the Eustachian tube in infants and young children with WS would contribute to a failure to open and evacuate. Collins, D. W. The phobia to foods has resolved. University Privacy Statement Gehr DD, Janssen T, Michaelis CE, Deingruber K, Lamm K. Middle ear and cochlear disorders result in different DPOAE growth behaviour: Implications for the differentiation of sound conductive and cochlear hearing loss. Interestingly, they also report that he may have experienced a mild depressive state when he was 12 to 13 years old. If individuals with WS are predisposed to noise-induced damage, then until the factors contributing to their susceptibility to noise-induced hearing loss have been clarified, any therapies incorporating acoustic training or conditioning with moderately intense sounds should be avoided. American Academy of Pediatrics Committee on Genetics.

The increase in otitis media in adults with WS may be related to ELN haploinsufficiency effects, i.e., less dense elastin in the hinge portion of the Eustachian tube [Bluestone, 2005]. Unauthorized use of these marks is strictly prohibited. The Williams syndrome: evidence for possible autosomal dominant inheritance. Some young children with Williams syndrome have elevations in their blood calcium level. State-Trait Anxiety Inventory (STAI) Profiles of 2 Adults With Williams Syndromea. Central nervous system injury-induced immune deficiency syndrome. It has been shown that typically developing children with unilateral hearing loss are at increased risk for academic failure and learning disabilities [Bess et al., 1998]. Potential conflicts of interest: Dr Ramos-Moreno has received grant/research support from the Spanish Ministry of Economy and Competitiveness (formerly Science and Innovation, PLE2009-0101, SAF2010-17167). One middle-ear structural disruption negatively impacting auditory function is the structure and orientation of the Eustachian tube and consequent disruptions of middle ear mechanics.

Lai, Zona bScores show normal values for Mr A (left panel) and higher values for Ms B (right panel). Thus, a common biological basis may be behind both OCD and bipolar disorder pathologies.44,45 Patients with OCD tend to have an imbalance of serotonin and dopamine levels in the prefrontal cortex.46 Drugs that increase serotonin output, such as SSRIs, reduce symptoms of OCD and are effective in bipolar disorder.4749 We postulate that it is likely that Williams syndrome neurologic pathologies stem from a similar biological basis as bipolar disorder, which is further validated by the finding that patients with Williams syndrome are highly responsive to SSRIs, as are patients with bipolar disorder.49 In addition, an imbalance in serotonin receptors has been reported in the prefrontal cortex of a Williams syndrome mouse model50 and has been linked to the pathogeny of bipolar disorder.51. Examples of procedural adjustments made in J.A.M.s lab are (1) inclusion of multi-frequency tympanometry and measuring tympanometry toward the end of the evaluation to minimize fear responses to probe tips and tympanometry stimuli (2) frequent alternation between air-conduction, bone-conduction, and speech testing, as these children better tolerate the pure-tone testing when interspersed with speech stimuli. However, an examination of Ms Bs total IQ score per the WAIS-III was 66. government site. Prevalence of hearing loss among children 6 to 19 years of age: the Third National Health and Nutrition Examination Survey. Mr As total IQ score per the WAIS-III was 56. Blue irides (77%) and a lacey or stellate pattern (74%) of the iris are characteristic. The School Age group (n = 43, 17 males, 26 females) ranged in age from 5.3317.92 years [mean CA (chronological age): 12.08 years, SD: 3.33 years, median CA: 11.67 years]. In most cases, the problem resolves on its own during childhood, but lifelong abnormality in calcium or Vitamin D metabolism may exist and should be monitored.

Jones, Wendy Precise life expectancy for those with WS is unknown. Strikingly, 12 of 14 participants with hearing within normal limits bilaterally had 4000-Hz DPOAE input/output (DPOAE IO) functions indicative of outer hair cell damage and impaired cochlear compression. We evaluated auditory function using two different methods in two separate settings. Wechsler Adult Intelligence Scale. 1996 Jan;49(1):28-31. Kielty CM. Gorga MP, Dierking DM, Johnson TA, Beauchaine KL, Garner CA, Neely ST. A validation and potential clinical application of multivariate analyses of distortion-product otoacoustic emission data. It is important to emphasize that across both children with WS and adults with WS, the frequency-sweep DPOAEs were significantly lower than would be expected given the behavioral hearing responses of the participants. Department of Communication Sciences and Disorders, James Madison University, Department of Psychological & Brain Sciences, University of Louisville. We made the worst-ear determination using a high-frequency pure-tone average of frequencies 4000 and 8000 Hz. [2001] found that at 4000 Hz, there was a significantly reduced range of stimulus intensity levels over which cochlear compression is clearly demonstrated. UK: Williams Syndrome . Proulx E, Young EJ, Osborne LR, et al. Tiffin J, Asher EJ. Williams syndrome ( WS ), also Williams-Beuren syndrome ( WBS ), is a genetic disorder that affects many parts of the body. The mathematics skills of almost all children with WS are markedly below grade level [OHearn and Luna, 2009] and for most, reading skills also are below grade level [Mervis, 2009]. Sensorineural hearing loss in children and adults with Williams syndrome. Otoacoustic emissions are very low-level sounds that can be measured in the ear canal when test stimuli are delivered via an in-the-ear probe. More detailed information with regard to treating and characterizing anxiety in Williams syndrome is needed for psychiatrists and neuropsychologists. An official website of the United States government. The elastin arteriopathy lead to thickened arterial walls with peripheral pulmonary stenosis and supravalvular aortic stenosis. 2003. Small amounts of fluid in the middle ear would result in poorer transmission of sound at higher frequencies. *Asterisks point out the weak abilities of both individuals. This participants audiogram (clinic protocol) showed hearing loss in the lower and higher frequencies but a threshold within normal limits at 2000 Hz. Features involving the prefrontal cortex such as executive functions (planning and mental flexibility) have so far been poorly studied in Williams syndrome.22,23 Here, we confirm and extend previous data on the executive functions as well as the decreased visual abilities.
