basilar part of pons, anterior limb or genu of internal capsule, corona radiata, basal ganglia, thalamus, cerebral peduncle The main symptoms are dysarthria and clumsiness (i.e., weakness) of the hand, which often are most prominent when the patient is writing; but dysarthria or involuntary movement can also be seen in legs.

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.

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]
Parisian journalist Jean-Dominique Bauby had a stroke in December 1995, and, when he awoke 20 days later, he found his body was almost completely paralyzed; he could control only his left eyelid. By blinking this eye, he slowly dictated one alphabetic character at a time and, in so doing, was able over a great deal of time to write his memoir ...
Anterior cerebral artery syndrome is a condition whereby the blood supply from the anterior cerebral artery (ACA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the medial aspects of the frontal and parietal lobes, basal ganglia, anterior fornix and anterior corpus callosum.
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]
SAH in CAA usually occurs in those who age more than 60 years, temporary motor and sensory deficits, and intracranial bleed in white matter adjacent to cerebral cortex. Basal ganglia, posterior fossa, and brainstem are spared. Boston criteria is used to determine the likelihood of a cerebral hemorrhage due to CAA.
Watershed stroke symptoms are due to the reduced blood flow to all parts of the body, specifically the brain, thus leading to brain damage. Initial symptoms, as promoted by the American Stroke Association, are FAST, representing F = Facial weakness (droop), A = Arm weakness (drift), S = Speech difficulty (slur), and T = Time to act (priority of intervention).
