Epilepsy is a condition caused by abnormal electrical activity in the brain that produces symptoms such as confusion, staring spells, and most commonly, episodes of involuntary shaking (seizures), which may be followed by periods of unconsciousness. Epilepsy usually begins in childhood.
Seizures may be generalized, involving the whole brain, or partial, where a part of the brain is involved. Generalized seizures may present as staring spells, unconsciousness, sporadic jerking movements, muscle rigidity, or loss of muscle tone causing your child to fall down. Partial seizures may produce changes in sensation (hearing, vision, smell, taste or touch), involuntary chewing, lip-smacking and other repetitive movements, and emotional disturbances.
