Left sided cerebellar stroke due to occlusion of a vertebral artery Cerebellar strokes account for only 2-3% of the 600,000 strokes that occur each year in the United States. [ 3 ] They are far less common than strokes which occur in the cerebral hemispheres .
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [ 2 ]
Moreover, focal narrowing of brain vessels and impairment of their ability to dilate in response to various stimuli may lead to a decreased cerebral blood flow and ultimately lacunar stroke. [11] Advanced age, chronic hypertension, smoking and diabetes mellitus are risk factors. It is unclear whether there is an association with alcohol ...
Lateral medullary syndrome is a neurological disorder causing a range of symptoms due to ischemia in the lateral part of the medulla oblongata in the brainstem.The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery. [1]
Red softening is one of the three types of cerebral softening. As its name suggests, certain regions of cerebral softening result in a red color. This is due to a hemorrhagic infarct, in which blood flow is restored to an area of the brain that was previously restricted by an embolism. This is termed a "red infarct" or also known as red ...
This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction/ischemic stroke. [2] It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage. [3] Ischemia leads to alterations in brain metabolism, reduction in metabolic rates, and energy crisis. [4]
Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex. [1]
Some of the most prevalent types include Alzheimer's disease, cerebral palsy, epilepsy, Parkinson's disease and stroke. [10] More specifically, the neurological diseases that can cause cerebellar degeneration include: [11] Diagram of two different nerve cells. The diagram on the left shows a nerve cell that is healthy and normally-functioning.
