The basal ganglia (or basal nuclei) are a group of nuclei of varied origin in the brains of vertebrates that act as a cohesive functional unit. They are situated at the base of the forebrain and are strongly connected with the cerebral cortex, thalamus, and other brain areas.

Basal ganglia disease refers to a group of physical dysfunctions that occur when the group of nuclei in the brain known as the basal ganglia fail to properly initiate movements.

Conditions that cause injury to the brain can damage the basal ganglia include:

  • Carbon monoxide poisoning
  • Drug overdose
  • Head injury
  • Liver disease
  • Infection
  • Metabolic problems
  • Multiple Sclerosis
  • Poisoning with copper, manganese, or other heavy metals
  • Side effects of certain medications
  • Stroke
  • Tumours
