Epilepsy: Generalized Seizures - Topic Overview
Epilepsy that causes generalized seizures is more common in children than in adults. Unlike partial seizures, which begin in a specific, often damaged area in the brain, generalized seizures cannot be traced to a specific location or focus. The abnormal electrical activity that causes seizures begins over the entire surface of the brain. And these seizures tend to affect the entire body.Epilepsy that causes generalized seizures may have no known cause (idiopathic), or it may result from another condition (symptomatic). Drug therapy is the usual treatment approach. But surgery may be helpful in some cases.
Juvenile Myoclonic Epilepsy - Topic Overview
Juvenile myoclonic epilepsy develops between ages 12 and 18. People with the disorder tend to have seizures that cause jerking in the shoulders or arms. Generalized tonic-clonic seizures and absence seizures may be present along with myoclonic seizures. Seizures often occur early in the morning.People with juvenile myoclonic epilepsy have normal intelligence and do not have other brain or nerve disorders. A family history of myoclonic seizures is present in about half of the people with the disorder. But the exact cause is unknown. Most people require lifelong treatment with medicine.
Aura and Seizures - Topic Overview
Aura is the term used to describe symptoms that may occur before a seizure. An aura may include:Visual changes. Examples include: Bright lights.Zigzag lines.Slowly spreading spots.Distortions in the size or shape of objects.Blind or dark spots in the field of vision.Hearing voices or sounds (auditory hallucinations).Strange smells (olfactory hallucinations).Feelings of numbness or tingling on one side of your face or body.Feeling separated from your body.Anxiety or fear.Nausea.An aura is often the first sign that you are going to have a seizure.
