Hello! Welcome and thank you for asking on HCM! Regarding your concern, I would explain that your symptoms may be related to an electrolyte imbalance or a sleep disorder. I recommend consulting with your GP for a careful physical exam and some blood lab tests (complete blood count, blood electrolytes, thyroid hormone levels, fasting glucose). A polysomnography would be necessary to exclude a possible sleep disorder. An EEG could also be helpful detect possible seizures. Hope to have been helpful! Best wishes, Dr. Aida
