<unk>  is routinely diagnosed with the use of an MRI because the majority of clinical symptoms are non-specific. Before the use of such imaging equipment, it was unable to be diagnosed until autopsy. The patient usually has a history of alcohol use disorder or malnutrition and neurological symptoms are sometimes present and can help lead to a diagnosis. MBD can be told apart from other neural diseases due to the symmetry of the lesions in the corpus callosum as well as the fact that these lesions don't affect the upper and lower edges. There are two clinical subtypes of MBD Type A- Stupor and coma predominate. Radiological imaging shows involvement of the entire corpus callosum. This type is also associated with symptoms of the upper motor neurons. Type B- This type has normal or only mildly impaired mental status and radiologic imaging shows partial lesions in the corpus callosum.
