Posterior Circulation Atrophy

Posterior Circulation Atrophy (PCA) refers to the progressive deterioration of the brain’s posterior circulation, which is the network of blood vessels supplying the back part of the brain. This area includes the occipital lobes, the cerebellum, and parts of the brainstem, which are crucial for vision, balance, and coordination.

Types of Posterior Circulation Atrophy

1. Occipital Atrophy: Loss of brain tissue in the occipital lobe, affecting vision.
2. Cerebellar Atrophy: Degeneration in the cerebellum, impacting balance and coordination.
3. Brainstem Atrophy: Shrinking of the brainstem, affecting vital functions like breathing and heart rate.
4. Mixed Type: Involves multiple areas such as the occipital lobe, cerebellum, and brainstem.

Causes of Posterior Circulation Atrophy

1. Atherosclerosis: Hardening of arteries reduces blood flow.
2. Hypertension: High blood pressure damages blood vessels.
3. Diabetes: High blood sugar harms blood vessels.
