Understanding Temporal Lobe Seizure -- the Basics

What Is a Temporal Lobe Seizure?

Temporal lobe, or psychomotor, seizures are caused by abnormal electrical activity in an area of the brain known as the temporal lobe. This abnormal activity results in temporary changes in movement, sensation, or autonomic function (such as heart rate and salivation). The patient may remain alert (simple seizure) or lose consciousness (complex seizure).

These seizures may be brought on by any number of factors, from head trauma to high fever. Often, no identifiable cause can be found. It's thought the seizures could be caused by scar tissue in the brain that occurred at birth. A person may experience a single, isolated seizure or a cluster of seizures during or following an illness or injury, without any further episodes. When seizures recur, the chronic condition is known as epilepsy.
