Overview

History and Symptoms

Although there is no sudden loss of abilities or exhibition of symptoms, there is a progressive decline.

Physicals

  • Dementia
  • Chorea movements:
    • Jerky movements
    • Uncontrollable movements
    • Although some exhibit very slow movement and stiffness
  • Loss of determination
  • Speaking is impaired with slurred words and uncontrollable movements of the mouth
  • Eating and mobility are extremely difficult if not impossible, and full-time care is required.

Cognitive : Abilities affected are;

  • Executive function
  • Planning; cognitive flexibility
  • Rule acquisition
  • Initiating appropriate actions
  • Inhibiting inappropriate actions
  • Slurring of the words and some uncontrollable movement of the lips
  • Perceptual and spatial skills of self and surrounding environment
  • Ability to learn new skills, depending on the affected parts of the brain.

Psychopathological : Psychopathological symptoms vary more than cognitive and physical symptoms, and may include


Common Symptoms

  • The common symptoms of Huntington`s disease are given below:[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][9][21][22][23][24]
    • Involuntary movements (Chorea) of face, trunk and limbs.
    • Parakinesia.
    • Hypotonia.
    • Hyperreflexia.
    • Dystonia of hands.
    • Mild bradykinesia is also observed.
    • Abnormal eye movements.
    • Conjugate eye movements.
    • Nystagmus.
    • Depression.
    • Paranoia, delusions, and hallucinations.
    • Loss of Cognitive functions.
    • Dementia.
    • Aphasia.
    • Apraxia.
    • Weight loss and cachexia.

Less Common Symptoms

  • Less common symptoms of Huntington`s disease are given below:[25][26]
    • Ataxia.
    • Myoclonus.
    • Seizures.
    • Generalized dystonia.
