Treatment of Irritability in Huntington’s Disease

Irritability is a common neuropsychiatric feature of Huntington's disease (HD), with prevalences varying from 38% to 73%. Similar prevalences of irritability are reported in other neurodegenerative disorders and traumatic brain injury, especially when the frontal lobe is involved. Before therapeutic interventions are initiated, the clinician should analyze the severity and frequency of the irri...

Irritability in pre-clinical Huntington's disease

Irritability, together with depression and anxiety, form three salient clinical features of pre-symptomatic Huntington's disease (HD). To date, the understanding of irritability in HD suffers from a paucity of experimental data and is largely based on questionnaires or clinical anecdotes. Factor analysis suggests that irritability is related to impulsivity and aggression and is likely to engage...

Huntingtin and the molecular pathogenesis of Huntingtons disease

Huntington’s disease (HD) is a late-onset neurodegenerative disorder that is caused by a CAG repeat expansion in the IT15 gene, which results in a long stretch of polyglutamine close to the amino-terminus of the HD protein huntingtin (htt). The normal function of htt, and the molecular mechanisms that contribute to the disease pathogenesis, are in the process of being elucidated. In this review...
