What should you know about TIA seizure?

A seizure may cause staring, altered awareness, stiffening, rhythmic jerking, unusual sensations, or confusion afterwards. A TIA more often causes sudden weakness or numbness on one side, facial drooping, speech trouble, or temporary loss of vision. TIA symptoms can clear, but that does not make them harmless; the episode may warn of a stroke. Low blood sugar, alcohol withdrawal, infection such as meningitis, and other brain or body problems can also trigger seizure-like events. The appearance alone cannot establish the cause.

If someone is having a seizure, move nearby hazards away, cushion the head, loosen tight clothing around the neck, and turn them on their side when the movements stop. Do not restrain them or put anything in their mouth. Note when it began and what happened before and after it. If sudden facial weakness, arm weakness, speech difficulty, or vision loss suggests a TIA, treat it as an emergency even if it resolves. Record the last time the person was known to be well.

Call emergency services for a first seizure, a seizure lasting longer than expected, repeated seizures without recovery, breathing difficulty, serious injury, or a person who remains unusually confused. Seek emergency assessment immediately for sudden one-sided weakness, facial drooping, trouble speaking, loss of balance, or vision change. Do not drive yourself after a suspected TIA or seizure. A clinician may need a neurological examination, blood tests, heart assessment, brain imaging, or an electrical brain test.

Ask what diagnosis best fits the episode, which warning signs should prompt an ambulance, whether medicines or alcohol could have contributed, and whether you need heart, brain, or blood-sugar testing. Ask when driving, swimming, working at height, or bathing alone can be resumed safely.
