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 ...
Such hemorrhages are typically located in the basal ganglia, cerebellum, or occipital lobes. Other location such as bleed within the cerebral cortex and intracranial bleed in people younger than 50 years should prompt further investigations on other causes of bleed such as brain tumour or cerebral arteriovenous malformation. The bleed can be ...
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]
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 ...
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]
The basal ganglia are located bilaterally, and have rostral and caudal divisions. The putamen is located in the rostral division as part of the striatum. The basal ganglia receive input from the cerebral cortex, via the striatum. This is a transverse section of the striatum from a structural MR image.
Charcot–Bouchard aneurysms are most often located in the lenticulostriate vessels of the basal ganglia and are associated with chronic hypertension. [1] Charcot–Bouchard aneurysms are a common cause of cerebral hemorrhage. Charcot–Bouchard aneurysm rupture might be linked to senile plaque formation in the Alzheimer's disease. [2]
Caused by shearing injuries at the time of impact, these contusions occur especially at the junction between grey and white matter and in the upper brain stem, basal ganglia, thalamus and areas near the third ventricle. [14] The hemorrhages can occur as the result of brain herniation, which can cause arteries to tear and bleed. [14]
