What should you know about gyratory seizure?

During a seizure, abnormal electrical activity in the brain can affect awareness, muscle tone, and coordinated movement. A person may turn their head or body, circle, or show one-sided movements; they may not remember the event afterwards. Similar movements can occur with fainting or other problems, so a description or video from a safe distance can help a clinician. Possible triggers or causes include low blood sugar, alcohol withdrawal, infection, head injury, or epilepsy.

Protect the person from nearby hazards, cushion their head, loosen tight clothing, and note when the movements begin. Turn them onto their side once it is safe, stay with them, and speak calmly as awareness returns. Do not restrain them, put anything in their mouth, or give food, drink, or tablets until they are fully alert. Arrange medical review after a first seizure or a change in the usual pattern.

Call emergency services if the seizure lasts several minutes, repeats without recovery, causes a serious injury, happens in water, or breathing does not return normally. Urgent help is also needed during pregnancy, with severe headache, fever, stiff neck, new weakness, or suspected poisoning. Low blood sugar can cause seizures; learn about [Hypoglycaemia](/conditions/hypoglycaemia/). [Meningitis](/conditions/meningitis/) and [Alcohol Use Disorder](/conditions/alcohol-use-disorder/) may also need specific assessment.

Ask what the movement pattern suggests, whether you need blood tests or brain imaging, how to reduce immediate risks, and whether a rescue medicine or seizure plan is appropriate. Tell the clinician about sleep loss, medicines, alcohol, illness, injuries, and what witnesses observed.
