taurine and Fragile X Syndrome

taurine has been researched along with Fragile X Syndrome in 11 studies

Fragile X Syndrome: A condition characterized genotypically by mutation of the distal end of the long arm of the X chromosome (at gene loci FRAXA or FRAXE) and phenotypically by cognitive impairment, hyperactivity, SEIZURES, language delay, and enlargement of the ears, head, and testes. INTELLECTUAL DISABILITY occurs in nearly all males and roughly 50% of females with the full mutation of FRAXA. (From Menkes, Textbook of Child Neurology, 5th ed, p226)

Trial Outcomes

ADHD Rating Scale 4th Edition

The ADHD Rating Scale is an 18-item scale directly derived from DSM-IV criteria for Attention Deficit Hyperactivity Disorder. The ADHD Rating Scale-IV is completed by the parent and scored by a clinician. The scale consists of 2 subscales: inattention (9 items) and hyperactivity-impulsivity (9 items). If 3 or more items are skipped, the clinician should use extreme caution in interpreting the scale. The total score can range from 0 to 54, with a higher score indicating greater severity. (NCT01300923)
Timeframe: Week 10

Brain-derived Neurotrophic Factor (BDNF)

BDNF is a protein that supports the survival of existing neurons and growth and differentiation of new neurons and synapses. (NCT01300923)
Timeframe: Screen and Week 10

Children's Yale-Brown Obsessive Compulsive Scale Modified for PDD

The Children's Yale-Brown Obsessive Compulsive Scales-Modified (CY-BOCS) is a 5-item, semi-structured clinician rating scale modified designed to rate the current severity of repetitive behavior in children and adolescents with PDD. Once the current repetitive behaviors are identified, they are separately rated on 5 items: Time Spent, Interference, Distress, Resistance, and Control. Each of these items is scored on a 5-point scale form 0 (least symptomatic) to 4 (most symptomatic). The CY-BOCS yields a Total Score from 0 to 20 and is sensitive to change. (NCT01300923)
Timeframe: Week 10

Clinical Global Impression- Severity Scale (CGI-S)

The Clinical Global Impression - Severity scale (CGI-S) is a 7-point scale that requires the clinician to rate the severity of the patient's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. Considering total clinical experience, a patient is assessed on severity of mental illness at the time of rating 1, normal, not at all ill; 2, borderline mentally ill; 3, mildly ill; 4, moderately ill; 5, markedly ill; 6, severely ill; or 7, extremely ill. (NCT01300923)
Timeframe: Week 10

Peabody Picture Vocabulary

The Peabody Picture Vocabulary Test is one of the most commonly used assessment tests that measure verbal ability in standard American English vocabulary. This test has been nationally standardized using examinees from various age groups, from children to adults. Thus, the raw scores are equated to mental age, using the norms obtained from standardization. The total standard scores range from 40 (worse receptive vocabulary) to 160 (better receptive vocabulary). The scores can also be converted to percentile rank. (NCT01300923)
Timeframe: Week 10

Social Responsiveness Scale

The 65-item SRS is a standardized measure of the core symptoms of autism. Each item is scored on a 4-point Likert scale. The score of each individual item is summed to create a total raw score. A total scores results are as follows: 0-62: Within normal limits 63-79: Mild range of impairment 80-108: Moderate range of impairment 109-149: Severe range of impairment (NCT01300923)
Timeframe: Week 10

The Aberrant Behavior Checklist (ABC)

The Aberrant Behavior Checklist (ABC) is a 58-item rating scale used to assess maladaptive behaviors across five original subscales: Irritability (15 items from 0-45), Social Withdrawal (16 items from 0-48), Stereotypy (7 items from 0-21), Hyperactivity (16 items from 0-48), Inappropriate Speech (4 items from 0-12). Additionally, Social Avoidance, a newly developed four-item subscale (from 0-12) of the ABC that captures core social avoidance aspects of Fragile X Syndrome is reported. All items on the ABC are rated from 0 (not at all a problem) to 3 (the problem is severe in degree). Higher scores indicate greater maladaptive behaviors. Differences between Baseline and Week 10 are used as an indicator of change. (NCT01300923)
Timeframe: Week 10

Vineland Adaptive Behavior Scales-II (VABS-II) Communication Domain

The VABS-II is a semi-structured interview designed to assess adaptive functioning in communication, daily living, socialization and motor skills. Recognizing that language is a major area of impairment in the study population, the Communication Domain (99 Items from 0-198), in particular the Expressive Subdomain (54 Items from 0-108) are of interest in this study. Items arranged in a developmental sequence are rated on a 3-point scale. Each item is scored from 0 (never performs the behavior) to 3 (usually performs the behavior independently). Higher scores indicate higher adaptive functioning. Differences between Baseline and Week 10 are used as an indicator of change. (NCT01300923)
Timeframe: Week 10
