Leukodystrophy is characterized by specific symptoms, including decreased motor function, muscle rigidity, and eventual degeneration of sight and hearing. While the disease is fatal, the age of onset is a key factor, as infants have a typical life expectancy of 2–8 years, while adults typically live more than a decade after onset.
These symptoms first start out with dysfunctions of the autonomic nervous system which result in symptoms such as abnormal functioning of both the bladder and bowel, recurrent blood pressure drops whenever patients stand up, and male erectile dysfunction. [8] [9] [10] Rarely, anhidrosis might also occur alongside these symptoms. [9] [8] [11] [10]
Recognition of the importance of this disorder as a cause of adult onset dementia and movement disorders was further heightened in 1997 at the Mayo Clinic when Dr. Zbigniew K. Wszolek identified a family with HDLS that was initially thought to be due to another disease process (FTDP-17), but only an autopsy of one and then other family members ...
The adult form commonly begins after age 16 often with an onset in the 4th or 5th decade of life and presents as a psychiatric disorder or progressive dementia. Adult-onset MLD usually progresses more slowly than the late infantile and juvenile forms, with a protracted course of a decade or more.
Leukoencephalopathy with neuroaxonal spheroids (LENAS), also known as adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP), hereditary diffuse leukoencephalopathy with spheroids (HDLS) and pigmentary orthochromatic leukodystrophy (POLD) [1] is an extremely rare kind of leukoencephalopathy and is classified as a neurodegenerative disease.
Leukoencephalopathy with vanishing white matter (VWM disease) is an autosomal recessive neurological disease. The cause of the disease are mutations in any of the 5 genes encoding subunits of the translation initiation factor eIF2B: EIF2B1, EIF2B2, EIF2B3, EIF2B4, or EIF2B5. The disease belongs to a family of conditions called the Leukodystrophies.
Time of onset also varies in frequency by location. Early infantile Krabbe Disease is the most common form of the disease overall, but Nordic communities tend to have even higher rates of early infantile onset Krabbe disease, while Southern European countries have higher incidences of late-onset cases.
It belongs to a group of disorders called leukodystrophies. It is characterized by early-onset enlargement of the head (macrocephaly) as well as delayed-onset neurological deterioration to include spasticity, epilepsy, and lack of muscular coordination. [1] MLC does not appear to be a disease that is fatal at birth or early in life despite its ...
