Huntington's Disease Case Study

Introduction

What is Huntington's Disease?

Huntington disease (HD) is an incurable, inherited disorder that occurs from gene mutation and results in the progressive degeneration of nerve cells in the brain[1].The basal ganglia is the primary location of degeneration, specifically the striatum located within it. The primary role of the basal ganglia is to coordinate movement so that it is smooth2. When the striatum degenerates, there is a decreased ability to inhibit unwanted movement3. This leads to an excessive amount of involuntary movement, known as chorea. HD affects the ability of individuals to move, think, and behave. HD typically first appears at the age of 30 to 40, however symptoms may present at any point in life1. HD occuring before the age of 20 is called juvenile Huntington’s disease.
