A variety of things can affect blood circulation: blood vessel health, blood pressure, thyroid function, hydration, heart health, exercise, and blood viscosity. (More on this in a moment.)
It may produce a wide range of neurological symptoms, such as headache, skin rashes, feeling very tired, joint pains, difficulty moving or coordinating part of the body, changes in sensation, and alterations in perception, thought or behavior, as well as the phenomena of a mass lesion in the brain leading to coma and herniation.
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.
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.

Edema, or swelling, of the brain may occur which increases intracranial pressure and may result in brain herniation. A stroke may result in coma or death if it involves key areas of the brain. [14] Other symptoms of cerebrovascular disease include migraines, seizures, epilepsy, or cognitive decline.
Stand up straight and align your head, shoulders, hips and ankles — most people jut their neck forward without knowing it, creating static tension there, so consciously move your head back so it ...
The pathophysiology of cranial venous outflow obstruction involves the disruption of normal venous drainage from the brain. Cerebral veins play a crucial role in draining brain interstitial fluid (ISF), and their significance has been linked in various neurological conditions. [1] It can be caused by extrinsic or intrinsic anomalies. [7]
Radiation-induced brain edema (RIBE) is a potentially life-threatening complication of brain tissue radiation and is characterized radiation necrosis, endothelial cell dysfunction, increased capillary permeability, and breakdown of the blood–brain barrier. [13] Symptoms include headache, seizure, psychomotor slowing, irritability, and focal ...
