Does ADEM show up on MRI?
Sequential imaging by MRI is sometimes required to confirm the diagnosis of ADEM, as the occurrence of relapses, with new lesions on MRI, is not compatible with a diagnosis of monophasic ADEM, and suggests that the correct diagnosis is either multiphasic ADEM or MS, based upon the clinical symptoms and neuroimaging …
Do ADEM lesions go away?
Acute disseminated encephalomyelitis (ADEM) is a rare kind of inflammation that affects the brain and spinal cord, usually in children. It damages the coating that protects nerve fibers, called myelin. Symptoms may be severe, but they can be treated. Most people make a full recovery and don’t have another attack.
How do you diagnose ADEM?
MRI scanning: Magnetic resonance imaging (MRI) scanning is an important part of the diagnosis. In ADEM, there are usually widespread, multiple changes deep in the brain in areas known as the white matter. The white matter is the part of the brain and spinal cord that contains the nerve fibers.
Does ADEM cause brain damage?
ADEM typically damages white matter (brain tissue that takes its name from the white color of myelin), leading to neurological symptoms such as visual loss (due to inflammation of the optic nerve) in one or both eyes, weakness even to the point of paralysis, and difficulty coordinating voluntary muscle movements (such …
Can you have mild ADEM?
The extent and progression of ADEM symptoms vary between affected individuals and may depend on the location of the brain lesions and the age of onset. Some individuals may have a mild, limited form of the disorder, while others may develop more severe symptoms.
How can you tell the difference between ADEM and MS?
ADEM generally consists of a single attack, while MS involves multiple attacks. In this instance, an MRI of the brain can help. MRIs can differentiate between older and newer lesions. The presence of multiple older lesions on the brain is more consistent with MS.
How is ADEM treated?
ADEM is usually treated with steroid medications such as methylprednisolone (Solu-Medrol). This medication is administered intravenously for five to seven days. You may also need to take oral steroids, such as prednisone (Deltasone), for a short time.
