Yesterday, my mother, who is 85, and who has some dementia. experienced immediate on-set muscle spasms in her upper body (arms and head) yesterday morning.. the twitching/spasms looked like Parkinson s. I took her to the emergency room at Kaiser because I was concerned she was having a stroke. Kaiser did a CAT scan, blood work and EKG which came back negative. She was released to return home. I have scheduled an appointment with a neurologist. This morning my mother s spasms were greatly diminished. Are there any underlying medical issues which cause spasms?
