Focal seizure

Focal seizure is a type of seizures caused by abnormal activity in just one area of your brain. There are two categories of focal seizures. One is focal seizure without loss of consciousness, and the other is focal seizure with impaired awareness. The former is previously called simple partial seizure. This condition may alter emotions or change the way things look, smell, feel, taste or sound. But it doesn't cause a loss of consciousness. It may also result in involuntary jerking of a body part, such as an arm or leg, and spontaneous sensory symptoms such as tingling, dizziness and flashing lights. The latter, once called complex partial seizures, may cause a change or loss of consciousness or awareness. In this condition, you may stare into space and not respond normally to your environment or perform repetitive movements, such as hand rubbing, chewing, swallowing or walking in circles.
