Idiopathic basal ganglia calcification is characterized by mineral deposits in the brain, an autosomal dominant pattern of inheritance in most cases and genetic heterogeneity. Basal ganglia disease is a group of physical problems that occur when the group of nuclei in the brain known as the basal ganglia fail to properly suppress unwanted movements or to properly prime upper motor neuron circuits to initiate motor function. Its prevalence increases with age, and the most affected site is the globus pallidus. Primary familial brain calcification is a condition characterized by abnormal deposits of calcium (calcification) in blood vessels within the brain.
