Neuropathology of hereditary diffuse leukoencephalopathy with axonal spheroids (HDLS)

Abstract

Hereditary diffuse leukoenchephalopathy with axonal spheroids (HDLS) is a disease showing progressive dementia and convulsion in humans at the age around 40's. HDLS usually shows autosomal dominant inheritance, but frequently has de novo occurrence. The causative gene is reported to be a gene encoding the colony stimulating factor 1 receptor (CSF1R). Neuropathological examination reveals severe loss of axons with axonal spheroids in the cerebral white matter. Microglia and astrocytes are upregulated in the lesions.
