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]
Encephalitis is inflammation of the brain. [5] The severity can be variable with symptoms including reduction or alteration in consciousness, aphasia, headache, fever, confusion, a stiff neck, and vomiting. [1] [6] Complications may include seizures, hallucinations, trouble speaking, memory problems, and problems with hearing. [1]
The basal ganglia (BG) or basal nuclei are a group of subcortical nuclei found in the brains of vertebrates. In humans and other primates , differences exist, primarily in the division of the globus pallidus into external and internal regions, and in the division of the striatum .
Many arboviral encephalitides, such as Japanese encephalitis, primarily affect the basal ganglia, sometimes causing motor symptoms such as involuntary movements and movements similar to those observed in Parkinson's disease.
Encephalitis is an inflammation of the brain. It is usually caused by a foreign substance or a viral infection. Symptoms of this disease include headache, neck pain, drowsiness, nausea, and fever. If caused by the West Nile virus, [29] it may be lethal to humans, as well as birds and horses.
The characteristic symptoms of Leigh syndrome are at least partially caused by bilateral, focal lesions in the brainstem, basal ganglia, cerebellum, and other regions of the brain. The lesions take on different forms, including areas of demyelination, spongiosis, gliosis, necrosis, and capillary proliferation. [9]
Common symptoms of viral meningitis include fever, headache, neck stiffness, nausea, vomiting, sensitivity to light and confusion, says Nagata. "In severe cases, it may cause seizures, coma or a ...
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]
