Temporal lobe seizures originate in the temporal lobes of your brain, which process emotions and are important for short-term memory. Some symptoms of a temporal lobe seizure may be related to these functions, including having odd feelings — such as euphoria, deja vu or fear.
During a temporal lobe seizure, you may remain aware of what's happening. During more-intense seizures, you might look awake but be unresponsive. Your lips and hands may make purposeless, repetitive movements. Temporal lobe seizures may stem from an anatomical defect or scar in your temporal lobe, but the cause is often unknown. Temporal lobe seizures are treated with medication. For some people who don't respond to medication, surgery may be an option.
A grand mal seizure — also known as a generalized tonic-clonic seizure — features a loss of consciousness and violent muscle contractions. It's the type of seizure most people picture when they think about seizures in general. Grand mal seizure is caused by abnormal electrical activity throughout the brain. Most of the time grand mal seizure is caused by epilepsy. In some cases, however, this type of seizure is triggered by other health problems, such as extremely low blood sugar, high fever or a stroke. Many people who have a grand mal seizure will never have another one. However, some people need daily anti-seizure medications to control and prevent future grand mal seizure.
