Ischemic Posterior Inferior Cerebellar Artery Stroke

Ischemic posterior inferior cerebellar artery (PICA) stroke is a medical condition that affects a vital part of your brain, the cerebellum. In simple terms, it happens when the blood supply to this area gets blocked or reduced, leading to various symptoms and complications. In this article, we’ll break down the types, causes, symptoms, diagnosis, treatment options, drugs, and surgeries related to PICA stroke in plain, easy-to-understand language.

Types of Ischemic PICA Stroke:

  1. Lateral Medullary Syndrome (Wallenberg Syndrome):
    • This type affects the lateral part of the medulla in your brainstem.
    • It can cause issues with swallowing, hoarseness, and balance problems.
  2. Medial Medullary Syndrome (Dejerine Syndrome):
    • It affects the medial part of the medulla.
    • Symptoms may include weakness on one side of the body and difficulty moving your tongue.
  3. Hemisensory Syndrome:
    • This type primarily affects sensory functions, causing numbness on one side of your body.
  4. Vestibular Syndrome:
    • It disrupts your balance and spatial orientation, leading to dizziness and unsteadiness.

Causes of Ischemic PICA Stroke

  1. Blood Clots: A clot in the PICA artery can block blood flow.
  2. Atherosclerosis: Buildup of fatty deposits in the artery walls.
