If it is what I think you are meaning, yes and it is called spasticity not sure of the spelling. I was first told, drink water and it will go away but it is not from dehydration it is just another signal gone awry.

I have found activity helps stop them but often painful. By activity, sudden quick movement of the area affected, will sometime cause the nerve to react to your movement and forget the twist and turn, and sometimes just working to resist them can be a challenge .

To answer your question... Yes.

Over active reflexes are a sign of an abnormality of a part of the nervous system called the pyramidal tracts. Anything that damages the pyramidal tracts can cause a number of symptoms including over active reflexes. Multiple Sclerosis can cause this clinical sign, but is not the only cause.

I have been dx w/MS. When I was in the hospital in 1/10 to r/o seizure disorder I had hyperactive reflexes. Recently when I went to my MD for my PE my reflexes were very slow.

What causes such variation? Is this a concern I should address w/my Neuro MD or is it just part of the MS changing?
