Epilepsy
Also known as: Seizure Disorder
Epilepsy is a chronic neurological disorder characterized by recurrent, unprovoked seizures caused by abnormal electrical activity in the brain. It affects people of all ages and can range from brief lapses in attention to severe convulsions. With proper treatment, about 70% of people with epilepsy can become seizure-free.
Symptoms
Temporary confusion or staring spells
Uncontrollable jerking movements of the arms and legs
Loss of consciousness or awareness
Psychic symptoms such as fear, anxiety, or déjà vu
Stiffening of the body
Falling suddenly without apparent cause
Lip smacking or other repetitive movements
Temporary inability to speak after a seizure
Causes
- Genetic factors and inherited epilepsy syndromes
- Brain injury from trauma, stroke, or infection
- Brain tumors or structural abnormalities
- Prenatal brain damage or developmental disorders
- Infectious diseases such as meningitis or encephalitis
Risk Factors
- Family history of epilepsy
- History of head trauma or brain injury
- Stroke or other vascular diseases
- Neurodegenerative conditions
- Childhood febrile seizures
- Central nervous system infections
Diagnosis
- Electroencephalogram (EEG) to detect abnormal brain wave patterns
- MRI or CT scan of the brain to identify structural causes
- Blood tests to rule out metabolic or infectious causes
- Neurological examination assessing motor and cognitive function
- Video EEG monitoring to capture seizure activity
Treatment
- Anti-seizure medications (levetiracetam, lamotrigine, valproic acid)
- Ketogenic diet, especially effective in children
- Vagus nerve stimulation (VNS) for drug-resistant epilepsy
- Responsive neurostimulation (RNS) device
- Epilepsy surgery to remove the seizure focus
- Lifestyle modifications including adequate sleep and stress management
Prevention
- Wear seatbelts and helmets to prevent head injuries
- Manage cardiovascular risk factors to prevent stroke-related epilepsy
- Ensure proper prenatal care
- Get vaccinated against infections that can cause brain inflammation
When to See a Doctor
- A seizure lasts more than 5 minutes
- Breathing or consciousness does not return after a seizure
- A second seizure follows immediately after the first
- You experience your first seizure at any age
