This case examines parkinsonian features in Huntington's disease, highlighting diagnostic challenges in late-onset cases.
Huntington's disease (HD) is a genetically inherited neurodegenerative disorder that affects about 1 in 10,000 people in the United States. It is typically characterized by adult-onset chorea. However, clinical presentations can be highly variable, posing significant diagnostic challenges. While chorea is the most common motor manifestation, a parkinsonian phenotype is a well-recognized alternative presentation, particularly in late-onset cases.
