Frontal Lobe Stroke Symptoms

Strokes can affect anyone, young or old. They can happen anywhere in the brain, inside or just outside of it. They occur when one or both of the major arteries carrying blood to the brain become clogged with plaque, eventually preventing blood flow. The frontal lobe is part of the cerebrum and is responsible for planning, organizing and problem solving. The symptoms of a frontal lobe stroke would affect these processes.


The frontal lobe is located in the front of the brain and controls motor function. The neurons in the frontal lobe are responsible for sending signals that initiate motor activities through the body.

A stroke in this section results in weakness or paralysis on the opposite side of the body, affecting muscles in the limbs, the face and the mouth. This will often limit the ability to speak clearly.
