Is multiple sclerosis a hereditary condition?

In part. Hereditary risk is one factor, but the interplay between genetic background and environment is likely in this disease. Identical twins studies show about a 30% risk for MS if one twin has the disease (certainly not 100%). Population studies show certain ancestry may increase or decrease risk (e.g. Northern european ancestry high, whereas asian, african, aboriginal very low).
NO. Although it occurs in those who are genetically susceptible, such as HLA-B-1*1501, in absence of added environmental factors, would not arise. Not a true heredity which is clearly passed from parents to children in any fashion, and familial incidence is truly rather low in offspring.
Multiple Sclerosis. A danish study does suggest that relatives of ms patients may be as much as seven times more likely to get the disease compared to people with no known relatives with the disease. This may be the result of common genetics.It could also be caused by common environmental exposures. No one knows for sure.. http://www.ncbi.nlm.nih.gov/pubmedhealth/pmh0001747/.

Is multiple sclerosis hereditary?

No proof. No conclusive proof that m s is transmitted by genetics ( hereditary) but slightly higher incidence is noted in some families. Read more...
Complex. Multiple sclerosis is an issue of genetic susceptibility, not the usual heredity, and risk runs about 3-5% if mother has it, 1-2% if father has it. But without specific environmental triggers, the disease will be unlikely to manifest. Read more...

What disease might mimic multiple sclerosis?

Several potentials. Cadasil, lupus, arteritis, clippers, pernicious anemia, cervical spondylosis, lyme disease, CNS lymphoma, sjogren's, melas. If you get the point, ms may be hard to diagnose, and often need to exclude other explanations. Patterns may or may not be different, and sometimes it is important to get testing and even several opinions. Read more...
Many. As dr. Mechanic said, there are mimics. Please see his answer for these. One thing he did not mention, is atypical migraines. Read more...

What disease has symptoms similar to that of multiple sclerosis?

Several. The confirmation of ms involves excluding several diseases that seem similar at times. Perhaps the biggest challenge is cadasil, a genetic disorder associated with migraines and small strokes. However, other disorders can cause confusion such as lupus, lyme disease, b-12 deficiency, sjogren's, arteritis, and a number of rare disorders. The MRI may seem similar in some of these cases.

Please help docs! Is multiple sclerosis hereditary?

Not primary cause. Ms is clearly influenced by genetics, as we are aware of risk profiles increasing genetic susceptibility and some genetic protective profiles; but, without a number of environmental influences, will not occur. So, like folks who get flu frequently, this is a vulnerability, but not a hereditary illness. Read more...

Which is inherited--muscular dystrophy or multiple sclerosis?

Muscular dystrophy. Muscular dystrophy is much more of an inherited disorder. Some are x-linked, others are autosomal. Heredity is not nearly as prominent in ms. Read more...
See answer below. Muscular dystrophies are inherited. Multiple sclerosis on the other hand is not thought of as a genetic disease. Read more...

Does multiple sclerosis have a hereditary component?

Yes. No single gene for MS has been found or likely to be found. Multiple genes have been identified which in different population studies worldwide seem to increase risk or protect against ms. The vast majority of these genes relate to immune system function. Genetic background, combined with environmental trigger likely trigger this disorder. Read more...

Not genetic disorder. Ms does seem to run in families, but does not occur as a hereditary condition. Rather, our genetic makeup confers either susceptibility or protection, and we have identified genes in both categories. Even if susceptible, without environmental influences, such as latitude, the disease will not occur. So, multiple factors play a role affecting our immune system expressions. Read more...

Is multiple sclerosis and sarcoidosis in the same disease family?

No relationship. Sarcoid affects lung, liver, predominantly, and brain far less frequently, and usually at base of brain, causing a bell's palsy perhaps. Ms affects brain and spinal cord, and stays within central nervous system. Does not affect lung or liver directly. Read more...

Are there effects of smoking to the disease multiple sclerosis? What are they?

BAD idea. Smoking increases risk of getting ms, and makes disease worse if pt does smoke. Very clear, in retrospect, that smoke is a mixture of many toxins, most of which can adversely affect the immune system. Stop smoking regardless of whether or not you have ms. Read more...

A friend of mine was recently diagnosed with primary progressive multiple sclerosis. Is this a fatal disease?

Cannot predict. Primary progressive ms is typically without rapid relapses, but also, without remission. Does not seem to respond well to meds employed in relapsing/remitting form. Most active therapy is symptomatic. However, research is ongoing with Gilenya (fingolimod) for ppms. Other drugs not yet on the market are being studied. Best bet is to get into one of these studies. Contact local medical school. Stay positive. Read more...
