Well the Acute disseminated encephalomyelitis is considered to be the part of the multiple sclerosis borderlines because it involves autoimmune demyelination. This disease is rare and the rate of affected people is about eight per one million people every year. Acute disseminated encephalomyelitis occurs mostly in children but overall it is seen that it can affect people of any age and related to any gender. Mostly this disease occurs to the children from the age around five to eight years. The death rate is 5% and according to research full recovery is seen in more than 60% patients. And about 70 to 90% patients recover with minor problems and disability. From two months to six months is the average recovery time.

Acute disseminated encephalomyelitis that is also known as ADEM produces inflammatory lesions in the spinal cord and in the brain and especially in the white matter. Normally these are found in the central and subcortrical white matter and in the cortical white junction of cerebellum, cerebral hemispheres, spinal cord and brainstem. In some cases the gray matter and the white matter of the basal ganglia, thalami and cortex may also be involved.

If a person suffers from a number of demyelinating episode then it is known as multiphasic disseminated encephalomyelitis or recurrent disseminated encephalomyelitis. The treatments for acute disseminated encephalomyelitis are available but most of them aggressive in behaviour and no controlled treatment are conducted on acute disseminated encephalomyelitis. The most common treatment of acute disseminated encephalomyelitis is the treatment by giving high doses of intravenous corticosteroids. These intravenous corticosteroids are mostly dexamethasone or methylprednisolone  and this procedure is followed for 3 to 6 weeks from lower doses to the maximum.
