Seizure alarm: what to know

Seizure alarms use signals such as movement, sound, or changes detected by a wearable device. They may be useful when a person has predictable movements during sleep, but ordinary movement, pets, bed vibration, or device position can trigger an alert. Some seizures involve little movement and may not be detected. Treat an alarm as one layer of support, not proof that a seizure has occurred or that no event occurred.

A clinician can help match the device to the seizure pattern, age, sleep setting, and communication needs. Discuss any contributing condition, including Alcohol Use Disorder, Hypoglycaemia, or Meningitis, rather than relying on an alarm to identify the cause.

Decide who receives alerts, who checks the person, and how emergency services will be contacted. Keep the device charged, fitted as instructed, and tested from the usual sleeping position. A responder should check breathing, remove hazards, protect the head, and avoid restraining movements or putting anything in the mouth. Record false alerts as well as confirmed events, because the pattern can help the clinician adjust the plan.

Respond promptly to an alert and call emergency services if the person is not breathing normally, cannot be woken, has serious injury, or has repeated or prolonged seizure activity. Seek urgent assessment after a first suspected seizure, a major change in the usual pattern, or an alert accompanied by severe headache, fever, stiff neck, or new weakness. Never silence an alert without checking the person.

Ask which seizure types the device is designed to detect, how alerts are transmitted, and what limitations apply in your home. Clarify response timing, privacy, charging, false alarms, and whether a diary or video would help review events. Ask for a written emergency plan.
