Summary

Story summary

Huntington disease (HD) involves CAG repeat expansions in the huntingtin gene, driving motor, cognitive, and psychiatric decline.
The loss of medium spiny neurons underpins these impairments.
Somatic CAG repeat expansions may contribute to disease progression, suggesting new therapeutic strategies.
Strategies target genetic and biological aging factors, while clinicians struggle to identify the optimal timing and measure clinical improvements.
A multidisciplinary approach is essential to advance HD research and develop treatments.
