Occipital epilepsy
Occipital Epilepsy
Occipital epilepsy (pronunciation: /ɒkˈsɪpɪtəl ˈɛpɪlɛpsi/), also known as occipital lobe epilepsy, is a type of epilepsy that originates in the occipital lobe of the brain.
Etymology
The term "occipital" is derived from the Latin word "occiput" meaning back of the skull, and "epilepsy" comes from the Greek word "epilēpsía" meaning seizure.
Definition
Occipital epilepsy is characterized by seizures that start in the occipital lobe, the region of the brain located at the back of the head. This area is responsible for processing visual information. Seizures may cause visual hallucinations, rapid eye blinking, and other eye-related symptoms.
Symptoms
Symptoms of occipital epilepsy can include:
- Visual hallucinations: Seeing flashing lights or colorful, circular patterns.
- Eye movement disturbances: Rapid blinking or involuntary eye movements.
- Headache: Often occurs before a seizure.
- Nausea: Can occur before or after a seizure.
- Seizure: Can involve convulsions, loss of consciousness, or other physical symptoms.
