Doctor's Notes on Seizures (Epilepsy) Symptoms, Signs, Causes, Types, and Treatment

A seizure is abnormal and uncontrolled electrical activity in the brain, that may result in a physical convulsion, minor physical signs, thought disturbances, or a combination of symptoms. There are different types of seizures, depending primarily on what part of the brain is involved.

Symptoms of seizures may range from jerking movements in a single extremity to abnormal movements throughout the entire body. Symptoms depend on which area of the brain the seizure originates. Some seizures may cause strange sensations, small repetitive movements such as picking at clothes or lip smacking, blank staring, crying out or making some sound, stiffening for a few seconds, the appearance of not breathing, a dazed or confused appearance, impaired consciousness, or repetitive blinking or other small movements, loss of bladder or bowel control, biting one’s own tongue, and a gradual return to consciousness, and confusion following the seizure.
