The bilateral basal ganglia region is a cluster of gray matter nuclei in the region on either side of the ventricles of the brain. The bilateral basal ganglia region consists mainly of the caudate nucleus, the nucleus pulposus, the nucleus pallidus, and the amygdala complex. The location of the bilateral basal ganglia region is in the white matter at the base of the cerebral hemispheres and is the deepest nucleus in the hemispheric division. There are connections between the basal ganglia and the cerebrum, cerebellum, hypothalamus, and spinal cord that work together to control and regulate body movements. Therefore, when the basal ganglia region is damaged bilaterally, it is easy for motor function to be impaired. For example, when there is hemorrhage or infarction in the bilateral basal ganglia region, patients may have symptoms such as hemiplegia and hemiparesis. In addition, lesions in this region may also cause Parkinson’s disease, chorea and other diseases. It is recommended that patients with the above symptoms seek medical examination in a timely manner and actively cooperate with doctors for treatment.
