LACK OF VITAMIN D AND MULTIPLE SCLEROSIS






Supplements of vitamin D



A major genetic study has confirmed the link between low levels of vitamin D and increased risk of multiple sclerosis.

Multiple sclerosis (MS), also called multiple sclerosis, disseminated sclerosis or polisclerosi, is a degenerative autoimmune disease that affects the central nervous system causing a wide spectrum of signs and symptoms. Multiple sclerosis affects the nerve cells making it difficult communication between the brain and spinal cord. Nerve cells transmit electrical signals through long fibers called axons, covered by myelin sheath. In multiple sclerosis, the immune defenses of the person attack and damage this sheath and axons are no longer able to effectively transmit signals. The name multiple sclerosis comes from the scars (sclerosis) that are formed in the white matter of the spinal cord and brain. The causes of multiple sclerosis are not clear to this day: some theories propose both genetic causes, is infectious; also they were highlighted correlations with environmental risk factors. The disease can manifest itself with a wide range of neurological symptoms and can progress to physical and cognitive disability. To date no cure has not been found.

Multiple sclerosis affects 2.3 million people worldwide.

The study signed by the team of Brent Richards at McGill University in Canada, published in PLoS Medicine, was conducted on a sample of 14,498 people to 24,091 controls, and has revealed that people with genetically lower levels of vitamin D have twice the risk of being diagnosed with multiple sclerosis.

"The results show that if a child is born with genes associated with a deficiency of vitamin D has twice the risk of developing adult multiple sclerosis, says Benjamin Jacobs service Infant Royal National Orthopedic Hospital in London. This might be because the lack of vitamin D causes multiple sclerosis or because there are other complex genetic interactions. " Will require an additional test to see if you can prevent the onset of the disease by intervening on levels of vitamin D.
