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]
Nine in ten people with cerebral venous thrombosis have a headache; this tends to worsen over the period of several days, but may also develop suddenly (thunderclap headache). [3] The headache may be the only symptom. [5] Many have symptoms of stroke: inability to move one or more limbs, weakness on one side of the face or difficulty speaking ...
Hemorrhage into the basal ganglia or thalamus causes contralateral hemiplegia due to damage to the internal capsule. [7] Other possible symptoms include gaze palsies or hemisensory loss. [7] Intracerebral hemorrhage into the cerebellum may cause ataxia, vertigo, incoordination of limbs and vomiting. [7]
Moyamoya disease is a disease in which certain arteries in the brain are constricted. Blood flow is blocked by constriction and blood clots (). [2]A collateral circulation develops around the blocked vessels to compensate for the blockage, but the collateral vessels are small, weak, and prone to bleeding, aneurysm and thrombosis.
A migraine headache can throw your whole day off track. But if you can learn to pick up on your subtle migraine warning signs, you might able to avoid the pain entirely, experts say. "This is a ...
For intraparenchymal hemorrhage associated with hypertension, small holes in arteries are thought to cause bleeding in the deep penetrating arteries of the brain, which are smaller and thinner than other arteries. These are the arteries that supply blood to the basal ganglia, the thalamus, the brainstem, and deep portions of the cerebellum ...
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 .
Other common symptoms are a pulsing noise in the head, progressive weakness, numbness and vision changes as well as debilitating, excruciating pain. [4] [5] In serious cases, blood vessels rupture and cause bleeding within the brain (intracranial hemorrhage). [a] In more than half of patients with AVM, this is the first symptom. [7]
