Is multiple sclerosis caused by a gene?

No. The cause of multiple sclerosis is unknown, there is some evidence that is related to a viral infection and there is evidence that genetics plays a part. However, there is no conclusive evidence that there is a single cause. In the end, we may find that "susceptible" individuals exposed to a trigger at the "right" age, with the right genetic profile go on to develop ms--thus a multifactorial cause.
Unsure. It is not clear there is one gene involved in multiple sclerosis. there may be many genes, there may be factors associated with genes, such as methylation, a so-called epigenetic effect. There are several known factors in the cause of MS, but for the most part, it is best to say we do not know what the cause is.
Not the standard way. Ms is an autoimmune mediated disorder, which occurs in genetically susceptible folks, if appropriate environmental influences are present. It is not a traditional genetic disease whatsoever, but may occur in families who have similar susceptibility genes.

What is the cause of multiple sclerosis and how is it realatedo to white mitochontrial dna?

Not known. We know this so far, ms is an autoimmune disease associated with genetic susceptibility, and environmental triggers (including increased incidence with prior ebv infections, low levels of vitamin d, growing up north of latitude 39, smoking, eating high fat, high salt diet, etc). Not sure what you mean by mitochondria, but these cellular contents are damaged by ms lesions. Read more...

Is multiple sclerosis passed on through genes?

Not sure. Ms is still being studies as to it's cuases. There seems to be an environmental component, but there seems to be more evidence that it can be genetic, where some people who have the "gene" may have a greater tendency to acquire ms. Read more...
Susceptibility. We know of several hla markers which increase genetic susceptibililty to ms: the best described is hla-dr-b-1, but dr1 and dr2 are also involved. Little question that this is only a small part of the puzzle. Read more...

Help! Is multiple sclerosis a result of single or multiple gene disorder or a chromosomal abnormality?

Not genetic mostly. There are no signs that multiple sclerosis is a sign of a chromosome disorder. Although there is likely a genetic component, this appears to be a very small role. This is not the type of disease where if you have the gene, you get the disease. It tends to be sporadic. It is an auto-immune disease where antibodies attack the white matter of the brain and/or spinal cord. Read more...
None of above. The genetic issues point toward risk or susceptibility, as MS is NOT a genetic or hereditary disorder. Read more...

Is optic neuritis always caused by multiple sclerosis?

Not always. But, if there is but one MRI white matter lesion associated with optic neuritis, about 75% of pts have developed clinically definite ms by 14 years. In other words, you may need followup for a period of time if you have suffered optic neuritis. Find an experienced ms specialized neurologist and discuss your situation. Read more...

Is optic neuritis sometimes caused by multiple sclerosis?

No. Though optic neuritis might be the first presentation in someone who will develop ms, there are many times when it is simply optic neuritis. A thorough history and examination by a neurologist can help address for you whether you might already have ms, or simply optic neuritis. Read more...
SURELY. Often presenting first sign of MS, and about 60% of cases of optic neuritis wind up becoming clinically definite MS. But if ON is associated with but one MRI lesion, there is an 80% chance of definite MS by 14 yrs. Read more...

Can lesions on the brain (as in multiple sclerosis) ever be caused by smoking ciggarettes?

No but.. There is no direct relationship but studies have shown that people with ms who smoke do worse! Read more...
Yes, Nonspecific white matter lesions can be due to cigarette smoking, and pattern would vary from MS, but smoking is risk for acquiring MS, and makes the disease worse. Read more...

How is the treatment for multiple sclerosis? Will my tinnitus (caused by multiple sclerosis) go away after I treat it?

Immune modulation. Treatment for ms is changing. The older medications required injections either daily to once a week. These medications reduced relapse rates and disability compared to no medication. Newer oral medications are much more effective in altering immune function, with much improved relapse rate reduction and disability. In regard to tinnitus, treatment will not cure it, but could prevent worsening. Read more...
Hard to predict. If you have Multiple Sclerosis, you should be using specific MS medication, and do NOT understand why you are using ginkgo, which is totally useless for any neurological disease. Tinnitus may be due to inner ear issue and best to evaluate using audiological/ otological testing. Read more...

Are there medications that can help with mobility problems caused by multiple sclerosis?

You bet! Anti-spasticity agents will assist the tightness in the legs, and you could try baclofen, tizanidine, maybe botox, etc. The newest agent touted to assist gait speed, and stamina, is called ampyra, (dalfampridine) but may not help everyone, just have to try it. Best way to address mobility problem is to be using the most effective potent medications, and supplementing with vitamin d. Read more...

What medications can help with nerve pain caused by my multiple sclerosis? I have tried gabapentin and oxcabazapine and both have stopped working. 

Others. Topiramate, pre-gabalin, lamotragine, any of the tcas. Typically, opiates are not the best for nerve and should avoided, but low dose Methadone may be an alternative. Talk to your doctor! Read more...
Change dose. You might have built up tolerance and need dose escalation. Titrate Gabapentin to 1200 mg 3xday or 900 4xday. If alreadymat 3600 mg per day consider switching to lyrica (pregabalin). Read more...
Still others. . Next in line would be Lyrica (pregabalin) and cymbalta. There are some others as well. Discuss your issues with your neurologist or who ever is managing your pain. Read more...
