What disease is characterized by dementia and "dance-like" movements?

Huntington's chorea is distinguished by the presence of neurological symptoms that include cognitive decline and chorea, which are involuntary, dance-like movements. This genetic disorder typically manifests in mid-adulthood and leads to progressive degeneration of nerve cells in the brain. The "dance-like" movements are a hallmark of the condition, resulting from the dysfunction of the basal ganglia, which are involved in movement control.

In addition to the motor symptoms, individuals with Huntington's chorea often experience symptoms of dementia as the disease progresses, which affects their cognitive abilities, memory, and personality. This combination of cognitive decline and hyperkinetic movements sets Huntington's chorea apart from other neurodegenerative diseases, making it a distinctive diagnosis.
