About Epilepsy
Neurological disorder causing recurrent seizures
Epilepsy is a central nervous system disorder in which brain activity becomes abnormal, causing seizures or periods of unusual behavior.
It can affect people of any age and may be caused by genetic factors, brain injury, or unknown causes.
Editorial update (28 September 2026): structured medical content awaits clinical reviewer sign-off.
How assessment may be approached
A clinician may review symptom onset, progression, weakness, sensation, vision, speech, cognition, balance and medicines. Neurological examination and selected imaging or laboratory tests may be used when indicated.
Care depends on the diagnosis and may involve medicines, rehabilitation, lifestyle support, monitoring or specialist review. Ask which findings were reassuring and which need urgent review.
When to seek prompt care
Seek emergency care for one-sided weakness, speech or face changes, sudden severe headache, seizure, fainting, new confusion, loss of vision, severe balance problems or rapidly progressing weakness.
