A frequently occurring motor deficit is left-sided hemiparesis (in strokes affecting the motor cortex). A less common motor deficit in this population is dysphagia. [4] Patients with right hemisphere brain damage often display sensory deficits such as left neglect, in which they ignore everything in the left visual field. [5]
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 ]
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]
Vascular dementia can sometimes be triggered by cerebral amyloid angiopathy, which involves accumulation of amyloid beta plaques in the walls of the cerebral arteries, leading to breakdown and rupture of the vessels. [2] [5] Since amyloid plaques are a characteristic feature of Alzheimer's disease, vascular dementia may occur as a consequence ...
Hemispatial neglect is a neuropsychological condition in which, after damage to one hemisphere of the brain (e.g. after a stroke), a deficit in attention and awareness towards the side of space opposite brain damage (contralesional space) is observed.
memory deficits (involvement of temporal lobe) hemineglect (involvement of parietal lobe) disorganized thinking, confusion, hypersexual gestures (with involvement of frontal lobe) lack of insight of his or her, usually stroke-related, disability; If the cerebellum is involved, ataxia might be present and this includes: altered walking gait
Memory and new learning involve the cerebral cortex, the subcortical projections, the hippocampus, the diencephalon and the thalamus, areas that often experience damage as a result of TBI. Frontal lobe lesions may also play a role in PTA, as damage to these areas is associated with changes in behavior, including irritability, aggressiveness ...
A brainstem stroke syndrome falls under the broader category of stroke syndromes, or specific symptoms caused by vascular injury to an area of brain (for example, the lacunar syndromes).
