Brain atrophy from vascular dementia: Specialty: Psychiatry, neurology Symptoms: Cognitive impairment, short-term memory loss [3] Complications: Heart disease, loss of ability to care for self and interact, pneumonia [4] Causes: Conditions that impair blood vessels in the brain and therefore interfere with oxygen delivery to the brain [3] Risk ...
The most common presentation of cerebrovascular diseases is an acute stroke, which occurs when blood supply to the brain is compromised. [13] Symptoms of stroke are usually rapid in onset, and may include weakness of one side of the face or body, numbness on one side of the face or body, inability to produce or understand speech, vision changes ...
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]
Symptoms of a stroke may vary, but can generally include the following, according to the Centers for Disease Control and Prevention (CDC): Sudden numbness or weakness in the face, arm, or leg ...
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
Posterior circulation infarct (POCI) is a type of cerebral infarction affecting the posterior circulation supplying one side of the brain.. Posterior circulation stroke syndrome (POCS) refers to the symptoms of a patient who clinically appears to have had a posterior circulation infarct, but who has not yet had any diagnostic imaging (e.g. CT Scan) to confirm the diagnosis.
The symptoms of a TIA typically resolve within 24 hours, unlike a stroke. Brain injury may still occur in a TIA lasting only a few minutes. Having a TIA is a risk factor for eventually having a stroke. [10] [11] Silent stroke is a stroke which does not have any outward symptoms, and the patient is typically unaware they have had a stroke.
Research is still needed in the area of cerebellar stroke management; however, several factors may lead to poor outcomes in individuals who have a cerebellar stroke. These factors include: Declining levels of consciousness; New signs of brainstem involvement; Progressing Hydrocephalus; Stroke to the midline of the cerebellum (a.k.a. the vermis) [4]
