Hi Thanks for posting your queRy on HCM I appreciate your concern for your mother. Central core disease is a rare genetic neuromuscular disorder that is classified as a congenital myopathy, meaning that it is a muscle disorder (myopathy). Most cases are inherited as autosomal dominant trait and associated with nonprogressive muscle disease and a favorable prognosis. There is no cure for this disease. Treatment is directed toward the specific symptoms that are apparent in each individual as you have mentioned. She may be at risk for Malignant hyperthermia (sudden severe increase in body temperature, muscle rigidity, hypertension altered level of consciousness) when exposed to certain general anesthetics or muscle relaxants. So, these drugs should not be given to her. Hope this answers your query.
