Posterior stroke

A posterior circulation stroke means the stroke affects the back area of your brain. This includes your brain stem, cerebellum (the area responsible for balance and coordination) and occiptal lobes (the area responsible for vision). Changes that may occur include the following.

Ataxia

You have a loss of coordinated arm or leg movements.

Double vision

You may have problems with your vision because your eye movement is limited in one or both eyes.

Vertigo

You have dizziness that makes you feel like you are spinning.

Visual field loss

You may not be able to see anything toward your left or right.
