Huntington Disease Overview

Huntington’s disease (HD) is a devastating, fully penetrant, autosomal dominant neurodegenerative disorder fundamentally driven by a deleterious CAG trinucleotide repeat expansion within the HTT gene, yielding a toxic, aggregation-prone mutant huntingtin (mHTT) protein. Clinically characterized by genetic anticipation—whereby successive generations frequently experience earlier disease onset and heightened severity—the core pathology is hallmarked by the profound, progressive atrophy of the striatum (specifically the caudate nucleus and putamen) and widespread cerebral cortical thinning. The distinct evolution of motor symptoms is directly dictated by the sequential vulnerability of striatal medium spiny neurons (MSNs); the early, selective destruction of enkephalin-expressing MSNs in the indirect pathway drives the pathognomonic hyperkinetic chorea, whereas the subsequent loss of substance-P-expressing MSNs in the direct pathway precipitates progressive rigidity, dystonia, and akinesia. Beyond movement abnormalities, patients present with a highly morbid clinical triad that includes devastating cognitive decline (subcortical dementia) and severe, often prodromal psychiatric disturbances, notably major depression, profound apathy, and impulsivity. Because no disease-modifying therapies currently exist to halt or reverse this fatal neurodegenerative cascade, the modern therapeutic paradigm remains strictly palliative. Clinical management relies entirely on a rigorous multidisciplinary approach, aggressively integrating targeted psychiatric pharmacotherapy with vesicular monoamine transporter 2 (VMAT2) inhibitors—such as tetrabenazine or deutetrabenazine—to definitively suppress severe chorea and maximize the patient’s functional quality of life throughout the irreversible disease trajectory.
