hemiballismus

Examples of hemiballismus in the following topics:

• Disorders of the Basal Ganglia

  • Hemiballismus is a hyperkinetic movement disorder that causes uncontrolled movement on one side of the body.
  • Since the internal segment of the globus pallidus (GPi) is the link in the circuit between the STN and thalamic projection, destruction of localized brain cells in the GPi via a pallidotony has proven to serve as a useful treatment for Hemiballismus.

• Basal Ganglia

  • With the exception of Wilson's disease and hemiballismus, the neuropathological mechanisms underlying diseases of ganglia such as Parkinsons' and Huntington's are not very well understood or are at best still developing theories.

• The Role of the Basal Ganglia in Movement

  • A different movement disorder, called hemiballismus, may result from damage restricted to the subthalamic nucleus.
  • Hemiballismus is characterized by violent and uncontrollable flinging movements of the arms and legs.
