Overview
Epilepsy is a common chronic neurological disorder that is characterized by recurrent unprovoked seizures. These seizures are transient signs and/or symptoms due to abnormal, excessive or synchronous neuronal activity in the brain. Epilepsy can be diagnosed based on history, symptoms and physical examination of a patient with seizure complain. Among the patients who present with clinical signs of seizures, the EEG is the most efficient test for diagnosis. Anti-seizure medications for epilepsy include drugs that affect voltage-dependent Na+ channels, drugs that affect Ca currents, drugs that affect GABA activity, drugs that affect glutamate receptor, and drugs with multiple mechanisms of action.
Causes
Life-threatening Causes
Life-threatening causes of epilepsy include:[1][2][3][4][5][6]

- Cerebral palsy
- Electrolyte disturbances
- Epileptic encephalopathy - Lennox-Gastaut type
- Febrile seizures
- Huntington's disease

Treatment
Shown below is an algorithm summarizing the treatment of [[disease name]] according the the [...] guidelines.
Do's
- Adults with an unprovoked first seizure should be informed that their risk of recurrence is higher within the first 2 years.[13]
- Treat with immediate antiepileptic therapy from the first unprovoked seizure, since it has been seen that it reduces recurrences, as compared with the delay of treatment pending a second seizure. This may not improve quality of life.[14]
Don'ts
- The content in this section is in bullet points.
