<unk>  (LENAS) is an extremely rare kind of leukoencephalopathy and is classified as a neurodegenerative disease. LENAS is a cause of severe and subacute dementia that results from damage to certain areas of the brain. This damage is to a type of brain tissue called white matter and axon damage due to swellings which are termed<unk> . The rarity and unknown prevalence of this disease may be due to most symptoms being similar to other common disorders, leading to misdiagnosis. LENAS normally has an adult onset (but also can be present in childhood), which can present on MRIs that mimics progressive multiple sclerosis and is thus misdiagnosed for this instead. The genetic etiology of LENAS is known to follow an autosomal dominant pattern through a mutation in the CSF1R gene.
