The individual may also feel as though the room is "spinning" or moving . Most causes of lightheadedness are not serious and either cure themselves quickly or are easily treated. Keeping a sense of balance requires the brain to process a variety of information received from the eyes, the nervous system, and the inner ears.
Thus dizziness can be caused by a variety of problems and may reflect a focal process (such as one affecting balance or coordination) or a diffuse one (such as a toxic exposure or low perfusion state). [8] Common causes of dizziness include: Inadequate blood supply to the brain due to: A sudden fall in blood pressure [7]
What causes vertigo and dizziness? “Dizziness is generally a more neurological cause or a potential cardiac cause. For example, it could be a blood flow issue or stenosis of a carotid artery ...
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.
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]
Causes of dizziness related to the ear are often characterized by vertigo (spinning) and nausea. Nystagmus (flickering of the eye, related to the Vestibulo-ocular reflex [VOR]) is often seen in patients with an acute peripheral cause of dizziness. [citation needed] Benign paroxysmal positional vertigo (BPPV) – The most common cause of vertigo ...
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.
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]
