<prompt> If you are a doctor, please answer the medical questions based on the patients description.I noticed my mother in law over the holidays holding her arm close to her body at her side and her hand would be in a fist, and always a slight tremor , she is on medication for seizures and in her early 60 s is this something related to her neurological problems or could this be something new like Parkinsons? She does not have seizures on a regular basis  <response>: Hi, Thank you for posting your query. I must congratulate you for your keen observation. Tremors along with rigidity as evidenced by a closed fist and arm held close to body could be suggestive of Parkinsons disease. However, this needs to be confirmed by a detailed neurological examination by a neurologist. These are unlikely to be due to her seizures or her antiepileptic Chat Doctor. Please get back if you require any additional information. Best wishes,
