Posterior Circulation Ischemia

Posterior circulation ischemia is a reduction in blood flow to the back of the brain, supplied by the vertebral and basilar arteries, which nourish the brainstem, the cerebellum, and areas linked to vision and balance.

Common symptoms: these may include dizziness or vertigo, balance problems, double or blurred vision, difficulty speaking or swallowing, and numbness; they often appear suddenly.

When to seek care? Any sudden onset of these symptoms requires immediate evaluation, since they may reflect a compromise of brain circulation.

Which specialist treats it? The neurologist is the professional who studies this type of condition and evaluates brain circulation. With sudden neurological symptoms, the most sensible thing is not to wait and to go immediately to a care facility.
