Huntingtons Disease: Symptoms
Early symptoms of HD include:

• Depression
• Mood swings
• Forgetfulness
• Clumsiness
• Involuntary twitching
• Lack of coordination

As the disease progresses, concentration and short-term memory diminish and involuntary movements of the head, trunk and limbs increase. Reflexes may be abnormal. The gait is often "prancing" and wide. Speech may be hesitant or enunciation poor. Eventually, walking, speaking and swallowing abilities deteriorate.
