XX. SCF LAYMAN’S SUMMARY
Huntington’s Disease is an inherited neurodegenerative disorder caused by an abnormal expansion in the HTT gene. The mutation produces a toxic form of the huntingtin protein that gradually damages brain cells, particularly those involved in movement, thinking, and behavior. Symptoms typically include involuntary movements (chorea), progressive cognitive decline, mood changes, and eventual loss of independence. SCF interprets Huntington’s Disease as a breakdown of neural communication and information-processing systems caused by toxic protein accumulation, resulting in progressive failure of motor, cognitive, and behavioral networks.
