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]
Dizziness is the sensation of imbalance or floating, impending loss of consciousness, and/or confusion. [2] This is different from vertigo which is characterized by the illusion of rotational movement [2] caused by the “conflict between the signals sent to the brain by balance- and position-sensing systems of the body”. [5]
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.
Symptoms of a brainstem stroke frequently include sudden vertigo and ataxia, with or without weakness. Brainstem stroke can also cause diplopia, slurred speech and decreased level of consciousness. A more serious outcome is locked-in syndrome. [citation needed]
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 ...
The underlying mechanism involves the nervous system slowing the heart rate and dilating blood vessels, resulting in low blood pressure and thus not enough blood flow to the brain. [2] Diagnosis is based on the symptoms after ruling out other possible causes. [3] Recovery from a reflex syncope episode happens without specific treatment. [2]
Roubleau describes the stroke as "a very, very large stroke," that covered a large part of the right side of her brain. "Another half hour, maybe, she was going to be paralyzed on half of her body ...
