Common signs and symptoms include:
- Headache, particularly one that hurts the most in the morning.
- Nausea and vomiting.
- Confusion or a decline in brain function, such as problems with thinking and understanding information.
- Memory loss.
- Personality changes or irritability.
- Vision problems, such as blurred vision, double vision or loss of peripheral vision.
- Speech difficulties.
- Seizures, especially in someone who hasn’t had seizures before.
