2. Involuntary Movements
In some cases, Huntington’s disease will initially manifest itself as small, uncontrollable muscle movements. In speaking with Prevention, Susan Perlman, MD, a neurologist and director of UCLA’s Huntington’s Disease Center of Excellence, says that the affected individual may not be aware of these changes, and that is it often friends or family who will notice “fingers always tapping or a twitch in the face.”
In the later stages of the disease, these small movements may evolve into more pronounced jerking or twitching—a condition known as chorea.
