The basal ganglia is a collective group of structures in the brain. These include the striatum, (composed of the putamen and caudate nucleus), globus pallidus, substantia nigra, and the subthalamic nucleus. Along with other structures, the basal ganglia are part of a neural circuit that is integral to voluntary motor function. [1]
Hemiballismus or hemiballism is a basal ganglia syndrome resulting from damage to the subthalamic nucleus in the basal ganglia. [1] It is a rare hyperkinetic movement disorder, [2] that is characterized by pronounced involuntary limb movements [1] [3] on one side of the body [4] and can cause significant disability. [5]
Basal ganglia disease is a group of movement disorders that result from either excessive output from the basal ganglia to the thalamus – hypokinetic disorders, or from insufficient output – hyperkinetic disorders. Hypokinetic disorders arise from an excessive output from the basal ganglia, which inhibits the output from the thalamus to the ...
[2] [1] First described in 1998 [6] and then genetically distinguished in 2005, [7] the disease is characterized by progressive brain damage that, if left untreated, can lead to coma and/or death. [1] Commonly observed in individuals with BTBGD is recurring subacute encephalopathy along with confusion, seizures, and disordered movement ...
Global aphasia is a severe form of nonfluent aphasia, caused by damage to the left side of the brain, that affects [1] ... basal ganglia, internal capsule, and ...
Hypokinesia patients experience these typical stress symptoms on a regular basis because of damage to the basal ganglia system. Therefore, when a hypokinesia victim is under stress, he or she does not display a typical fight-or-flight response, placing the patient under greater danger from potentially harmful stimuli. [ 38 ]
Neuroferritinopathy is classified as a late-onset basal ganglia disease and is a dominantly inherited neurodegenerative disease. [3] Four different alleles are responsible for neuroferritinopathy. Three arise from nucleotide insertions in the ferritin light chain (FTL) polypeptide gene while the fourth arises from a missense mutation in the FTL ...
Athetosis is a symptom primarily caused by the marbling, or degeneration of the basal ganglia. [citation needed] This degeneration is most commonly caused by complications at birth or by Huntington's disease, in addition to rare cases in which the damage may also arise later in life due to stroke or trauma.
