Excessive irritability

From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history

Presentation[edit | edit source]

Prevalence[edit | edit source]

  • Katrina Berne reports a prevalence of 70-90% for mood swings, excessive irritability, and overreaction in people with chronic fatigue syndrome.[1]

Symptom recognition[edit | edit source]

  • In the Holmes criteria, excessive irritability is an optional criteria for diagnosis, under the section Minor Symptom Criteria - Neuropsychologic Complaints.[2]

Notable studies[edit | edit source]

Possible causes[edit | edit source]

Potential treatments[edit | edit source]

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).[3] Very low dose amisulpride has also been shown to reduce the fatigue and bodily symptoms of ME/CFS[4]. N-acetyl-cysteine can help the irritability in autism, but the research showed this is not quite as effective as atypical anti-psychotics.[5]
