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]
Corticobasal degeneration (CBD) is a rare neurodegenerative disease involving the cerebral cortex and the basal ganglia. [1] CBD symptoms typically begin in people from 50 to 70 years of age, and typical survival before death is eight years.
Neurodegeneration with brain iron accumulation is a heterogenous group of inherited neurodegenerative diseases, still under research, in which iron accumulates in the basal ganglia, either resulting in progressive dystonia, parkinsonism, spasticity, optic atrophy, retinal degeneration, neuropsychiatric, or diverse neurologic abnormalities. [1]
Alzheimer's disease (AD) is a chronic neurodegenerative disease that results in the loss of neurons and synapses in the cerebral cortex and certain subcortical structures, resulting in gross atrophy of the temporal lobe, parietal lobe, and parts of the frontal cortex and cingulate gyrus. [14]
Primary familial brain calcification [1] (PFBC), also known as familial idiopathic basal ganglia calcification (FIBGC) and Fahr's disease, [1] is a rare, [2] genetically dominant or recessive, inherited neurological disorder characterized by abnormal deposits of calcium in areas of the brain that control movement.
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 ...
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 ...
Most Parkinson's disease cases are sporadic, though contributing factors have been identified. Pathophysiology involves progressive degeneration of nerve cells in the substantia nigra, a midbrain region that provides dopamine to the basal ganglia, a system involved in voluntary motor control.
