Cause 4. Stroke: An Abrupt Assault on the Brain
Considered a medical emergency, stroke occurs when blood flow to a part of the brain gets interrupted, depriving it of oxygen and vital nutrients. Strokes affecting the vessels supplying the cerebellum can result in cerebellar ataxia. The onset is often sudden, resulting in immediate and significant changes in the individual’s motor abilities.
Ischemic strokes, caused by a clot or blockage within the cerebellar arteries, can lead to acute cerebellar ataxia. Symptoms may include uncoordinated movements, gait abnormalities, and a lack of balance – all characteristic of ataxia. On the other hand, hemorrhagic strokes, resulting from a ruptured blood vessel, can cause a rapid buildup of blood and pressure on the cerebellum, impairing its functions and causing ataxia.
While these causes discussed thus far – genetic mutations, alcohol abuse, autoimmune diseases, and stroke – are quite varied, they all converge on one point: their effect on the cerebellum, leading to the manifestation of cerebellar ataxia. The multi-pronged etiology of this condition indicates a necessity for a comprehensive and personalized approach to its diagnosis and treatment. (4)
