Yes, I do! - and these were found initially on my very first neuro exam (12years ago).

Hyperactive reflexes may indicate a spinal cord lesion (not necessarily MS - other spinal cord conditions could be the cause also.)

There is a number given when the brisk reflexes are found, such as +2, +3, +4, +5 etc. The higher the number, the more likely there is some spinal cord involvement.

With +4 and +5, there are usually sustained, repetitive movements, also called clonus. This has something to do with the nerve receptor signals traveling the spinal cord and going to the muscle/tendon.

Hope this helps a little.

Take care,
KoKo

Hi donnainct, I think the best person to ask why a MRI wasn't done would be your neuro!

As far as all with MS having hyperactive reflexes, this too is hard to tell as we are all so different with placements of lesions. We were just talking about this a few days ago.... for a lighthearted approach to kicking your neuro and other things, read the post "Lol @ Docs and their in-office exams" Not meant to be offensive, just taking the edge off

Take care!

Brisk reflexes doesn't necessarily mean MS, nor does it mean you have a spinal lesion. Brisk reflexes can be caused by other things, such as medications or anxiety/nervousness.

When the reflexes are extremely brisk, they're called hyper-reflexes. The neuro can grade the reflexes as 0, +1, +2, +3, +4, +5.

With the higher numbers, there can be clonus. I have the sustained clonus movement. When my knee tendon is tapped, my leg kicks out, then it keeps jerking several times.

Does this make more sense? Sorry if I've confused you.

Take care,
KoKo

Yes. I have brisk reflexes too. I always thought that was a good sign. My doctor said it is a bad sign. She didn't explain to me what that meant.

I had brisk knee reflexes for a year or so (and about kicked my neurologist off her stool!), but then they went back to normal, though at my last appointment I had no reflexes in my right knee at all. I also never have any ankle reflexes. And I have at times had brisk arm reflexes too.

Is it normal for them to come and go like that?

Question absent or demensioning reflexes ?

I just read that thread on brisk reflexes and I have the opposite problem. My numbers from my hips +2,legs ankles +2,knees +2,arms +3 . with sensory damage in legs,feet,arms and hands. I'll be doing a repeat emg this Weds. and a mri w/wo contrast of brain ,c-t spine on aug.1
I was unable to do the heel leg touch test or the finger to nose test (tremors).
So I'm dx. with RRMS and lupus (SLE) hughes syndrome,vasculitis . These are just the main problems I have.
Am trying to be brave but clearly something is wrong. Has anyone here know of why this could be happening? I know that ya'all aren't doctors but maybe someone here can give me a clue as to what this might be . My Neuro isn't saying much now.

Thanks all

info on reflexes

Here is some info on reflexes, with the grading scale. Still trying to find a site that explains reflexes a little better.

This is from New York University School of Medicine:

http://cloud.med.nyu.edu/modules/pub.../reflexes.html


This is from US National Library of Medicine, NIH site:

http://www.ncbi.nlm.nih.gov/books/NBK396/

Take care,
KoKo

Thank you Koko
I was misinformed thinking that it was +2 being a problem and its the +3 -5 or +1 thats the problems areas . So I'd disregards me +3 and +4 reading thinking that it was normal. Makes more sense now.

Hopefully we didn't cause your thread to get too far off track. It stimulated more questions about reflexes. Thanks for starting it.

It's always best to ask the doctor, but..........my doctor is like yours, and won't always explain things very well, even when asked.

Take care,
KoKo

I was just reading that they call this hyperreflexia . It can happen with people with problems in the spine or autonomic nevious systems. Please excuse spelling.

Hyperreflexia is defined as overactive or overresponsive reflexes. Examples of this can include twitching or spastic tendencies, which are indicative of upper motor neuron disease as well as the lessening or loss of control ordinarily exerted by higher brain centers of lower neural pathways (disinhibition). See Autonomic dysreflexia.
Causes

The most common cause of hyperreflexia is spinal cord injury (see autonomic dysreflexia). Standard stimuli like the filling of the bladder can cause excessive responses from the nervous system, such causes are not known.

But hyperreflexia can be developed via many other causes, including medication and stimulant side effects, electrolyte imbalance, serotonin syndrome and severe brain trauma.
Treatment

Treatment depends on diagnosing the specific pathology causing this symptom. Should it be caused by use of stimulants or other substances, then it may involve removing these drugs from use.
