gamma-aminobutyric acid and Rett Syndrome

gamma-aminobutyric acid has been researched along with Rett Syndrome in 26 studies

gamma-Aminobutyric Acid: The most common inhibitory neurotransmitter in the central nervous system.
gamma-aminobutyric acid : A gamma-amino acid that is butanoic acid with the amino substituent located at C-4.

Rett Syndrome: An inherited neurological developmental disorder that is associated with X-LINKED INHERITANCE and may be lethal in utero to hemizygous males. The affected female is normal until the age of 6-25 months when progressive loss of voluntary control of hand movements and communication skills; ATAXIA; SEIZURES; autistic behavior; intermittent HYPERVENTILATION; and HYPERAMMONEMIA appear. (From Menkes, Textbook of Child Neurology, 5th ed, p199)

Trial Outcomes

Efficacy of Sarizotan Assessed by the Caregiver-rated Impression of Change

"Caregiver-rated Impression of Change (CIC): 7-point scale requiring the caregiver to rate how much the patient's illness has improved or worsened relative to the baseline state.~7-point Likert-type scale for which ratings range from 1 = very much improved to 7 = very much worse, with 4 = no change. This caregiver-rated measure considered activities, behavior, mood and functioning. This rating was performed in consultation with the study Investigator but was based largely on the caregivers' evaluation during the reporting period. The single rating of the CIC was to be based on changes in the following domains: • Activities (watching TV, interest in conversations around her, cooperation during toileting, dressing/bathing, etc.), • Communication (verbal or by eye movements, hand movements, or head movements), • Behavior (agitation, refusal to feed, scratching, social avoidance), • Participation in family/outdoor/social events)" (NCT02790034)
Timeframe: 24 weeks
