There are other, less common, problems that can happen after a stroke.

Epilepsy

Epilepsy is a condition that causes you to have repeated fits or attacks, known as seizures.

Some people will have a seizure after a stroke. These are known as acute or onset seizures and normally happen within the first 24 hours. 

If you have an onset seizure, it does not mean that you have or will go on to develop epilepsy. However, a small number of people do. 

Although epilepsy can’t be cured, you can usually prevent seizures by taking medication. 

Hallucinations

A hallucination is when you see or hear something that isn’t there. 

If a stroke damages a part of your brain called the midbrain, you may experience hallucinations. These hallucinations often involve vivid, colourful scenes with animals, people and patterns.

Hallucinations usually start within a few days after having a stroke. They may disappear within a few weeks, but they can sometimes last for years. Even if hallucinations do last, they usually become less intense over time.

Sometimes losing some of your sight can cause hallucinations too. 

Locked-in syndrome

Occasionally stroke can cause locked-in syndrome. This is a very rare condition where the only part of your body that you can move is your eyes.

You are still able to think and reason when you have locked-in syndrome and you’re aware of what’s going on around you, but you can’t speak or move. Some people are able to communicate using eye movements or blinking.
