How long does it take for MS to cause symptoms of dementia?

Unpredictable. Ms doesn't always lead to dementia. Some people have rapidly deteriorating courses & others are fairly stable.
VARIABLE. The overall prevalence of cognitive issues is at least 65% of all ms patients, but the issues are usually mild to moderate. Severe problems tend to involve only about 10% of all patients. However, we do find subtle cognitive issues even in many pts with the earliest of signs (cis) if we search carefully. Fatigue may contribute to further disability. Use potent meds.

YOU HAVE: A proven skin punch biopsy diagnosis of small fiber neuropathy, and you possess one of the many causes of such an entity. Could be pre-diabetes, but with the ANA issues, might look further into collagen vascular categories. Other considerations, include Celiac disease, Sjogren's, HIV, paraproteinemias, B-12, etc. Would check anti-GM-1 with IgG, IgM, as you might have an autoimmune sensory neuropathy, and might respond to a course of IVIG.

Not clear need more data. There are a lot of things we need to see. Saying lupus tests are negative. She notes Lupus and MS in the family and there is a + ANA but what were the other results and were they done at an accurate laboratory. Some laboratories do not do these tests accurately. The same can be said about the other lab tests. Your evaluation depends on an accurate evaluation. Some of the symptoms you have are charteristic of fibromyalgia - was that tested for?

Difficult Case. It sounds like you have a small fiber neuropathy; however, the reasons for this can be numerous and can be quite elusive to even the most brilliant neurologists. I see cases like this rarely, and they are rare. Whenever we get to the point where we just don't know, it is always worth the patient's time to seek care across the country at quaternary centers (e.g. Mayo Clinic). Read more...
University. Not all symptoms can lead to a definite diagnosis. Some things are just beyond our current knowledge. If you want more expert opinions, see a university specialist near you. Sometimes, those who do research know more about uncommon diseases. However, seeking another opinion has to be weighed against how serious or costly this problem is. Read more...
Likely. autoimmune small fiber neuropathy. Not sure what specific labs were negative but high yield labs would be fasting glucose, GTT, HgBA1C, SSA, SSB, salivary gland bx, serum ACE, SPEP, serum free light chain, TTR gene sequencing, SCN9A testing, and serum alpha-galactosidase levels. Did muscle bx include biochemical testing to assess mitochondrial function? Read more...

I've seen worse physical symptoms resolve with appropriate mental health treatment. The mind and body are connected. Read more...

Rarely, genetic conditions such as Fabry's disease or acquired amyloid. You need to see someone with better understanding. Read more...
