How is Huntington's chorea primarily characterized?

Huntington's chorea, also known as Huntington's disease, is primarily characterized by a decline in cognitive function alongside involuntary movements, commonly referred to as chorea. The progression of the disease leads to significant neurological changes that result in memory loss, difficulties with reasoning, and changes in mood and personality. These cognitive changes are often pronounced and become more evident as the disease progresses, affecting the individual's ability to think through problems and manage daily tasks.

While other symptoms, such as involuntary movements and coordination difficulties, are associated with Huntington's disease, the hallmark of the condition lies in the cognitive impairment it produces. Therefore, recognizing the loss of cognitive function is crucial for understanding the full impact of Huntington's chorea on an individual's health and daily living.
