There are a few medical emergencies that can be caused by CACNA1A variants, including seizures and hemiplegic migraines. A Seizure (or hemiplegic migraine) Action Plan contains tailored guidelines on how to respond during a seizure or hemiplegic migraine, based on the patient’s medical history. It includes health and medical information specific to the patient. Importantly, a plan helps others to recognize seizures or hemiplegic migraines and details steps that can and should be taken to keep him or her safe from injury or damage caused by CACNA1A-related neurological events.
