ADEM Diagnosis and Tests No one test can spot ADEM. Doctors most often diagnose it with MRI (pictures of your brain made with a large magnet and radio waves) and a lumbar puncture (fluid drawn from around the spinal cord and then tested). Your doctor will try to rule out conditions with similar symptoms.
Encephalitis is inflammation of the active tissues of the brain caused by an infection or an autoimmune response. The inflammation causes the brain to swell, which can lead to headache, stiff neck, sensitivity to light, mental confusion and seizures.
ICD-10 | Cerebral infarction, unspecified (I63. 9)
The National Institute of Neurological Disorders and Stroke (NINDS) has described encephalopathy as a term for “any diffuse disease of the brain that alters brain function or structure” and says the “hallmark of encephalopathy is an altered mental status.” It then proceeds to list a hodge-podge of acute and chronic ...
Autoimmune encephalitis (AE) is a type of brain inflammation where the body's immune system attacks healthy cells and tissues in the brain or spinal cord. It is a rare, complex disease that can cause rapid changes in both physical and mental health.
Seronegative autoimmune encephalitis is a subcategory of autoimmune encephalitis diagnosed when autoimmune antibodies are not detected in cerebrospinal fluid (CSF) or serum [2-3].
Acute disseminated encephalomyelitis (ADEM) is characterized by a brief but widespread attack of inflammation in the brain and spinal cord that damages myelin – the protective covering of nerve fibers. ADEM often follows viral or bacterial infections, or less often, vaccination for measles, mumps, or rubella.
Inflammation of the meninges, the membranes that surround the brain and spinal cord, is called meningitis; inflammation of the brain itself is called encephalitis. Myelitis refers to inflammation of the spinal cord. When both the brain and the spinal cord are involved, the condition is called encephalomyelitis.
In most but not all cases, ADEM occurs only once, while patients with MS have further, repeated attacks of inflammation in their brains and spinal cords. In most cases, ADEM patients do not develop new scars on a repeat MRI scan whereas MS patients typically experience new scars on their follow-up MRI scans.
