My 22 year old daughter has involuntary contractions of her abdominal and leg muscles that can be violent, causing her to thrash about. Occurs 1-3 times per day. Lasts 5-30 minutes. She is awake and alert during them. Usually occur in the evening, but can occur at any time. She is 2.5 years post Chiari I surgery. Since that surgery she has had a shunt placed due to high intracranial pressure and has had two cranioplasties and repair of pseudomeningocoele (bulging of the artificial dural patch). The seizures began a year after her first cranioplasty. Surgeons thought they might resolve after shunt placement and repair of meningocoele, but they have not, several months later. Neurologist thought they might be due to zoloft, but she has been off it for three weeks with no improvement. Other meds are trazadone, ambien and oxycodone (which she is weaning off), florinef, atenolol. Hospital-based EEG was normal, even during the seizures. Where do we go from here? What could be causing her problem? This is taking a severe emotional toll. Thank you!
