Potential treatments
Severe irritability is a common symptom in autism, and the main treatment for this is atypical anti-psychotic drugs such as amisulpride ( Solian), risperidone (Risperdal) or aripiprazole (Abilify). Very low dose amisulpride has also been shown to reduce the fatigue and bodily symptoms of ME/CFS. N-acetyl-cysteine can help the irritability in autism, but the research showed this is not quite as effective as atypical anti-psychotics.
