Reflex epilepsy
Reflex epilepsy
Reflex epilepsy (pronounced: /ˈriː.flɛks ˈɛp.ɪˌlɛp.si/) is a type of epilepsy where seizures are triggered by specific stimuli or activities. The stimuli can vary from person to person and can be as diverse as reading, hot water, or flashing lights.
Etymology
The term "reflex" in reflex epilepsy is derived from the Latin reflexus, meaning "bent back", and the Greek epilepsia, meaning "to seize". This reflects the nature of the condition where a specific stimulus triggers a seizure.
Types of Reflex Epilepsy
There are several types of reflex epilepsy, including:
- Photosensitive epilepsy: Seizures are triggered by flashing or flickering light.
- Reading epilepsy: Seizures are triggered by reading.
- Hot water epilepsy: Seizures are triggered by hot water on the head or body.
- Musicogenic epilepsy: Seizures are triggered by certain types of music or specific frequencies of sound.
Diagnosis
Diagnosis of reflex epilepsy is typically made through a combination of medical history, physical examination, and diagnostic tests such as an EEG. The specific trigger for the seizures is often identified through patient history or through exposure to potential triggers in a controlled environment.
Treatment
Treatment for reflex epilepsy typically involves avoiding the specific trigger where possible, and medication to control seizures. In some cases, surgery may be considered if medication is not effective.
