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]
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.
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.
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.
The neurological disorders and symptoms which occur with VWM are not specific to countries; they are the same all over the world. [4] Neurological abnormalities may not always be present in those who experience onset as adults. Symptoms generally appear in young children or infants who were previously developing fairly normally. [citation needed]
A new study is illuminating how “forever chemicals” can alter our brain cells by impairing the genes that maintain healthy neurons, the cells of our nervous system.
An average clinical profile from published studies shows that the median onset age for HDLS patients is 44.3 years with a mean disease duration of 5.8 years and mean age of death at 53.2 years. [ 2 ] [ 11 ] As of 2012, there have been around 15 cases identified with at least 11 sporadic cases of HDLS.
