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.
Krabbe disease (KD) (also known as globoid cell leukodystrophy [3] or galactosylceramide lipidosis) is a rare and often fatal lysosomal storage disease that results in progressive damage to the nervous system. KD involves dysfunctional metabolism of sphingolipids and is inherited in an autosomal recessive pattern.
The incidence of metachromatic leukodystrophy is estimated to occur in 1 in 40,000 to 1 in 160,000 individuals worldwide. [13] There is a much higher incidence in certain genetically isolated populations, such as 1 in 75 in Habbanites (a small group of Jews who immigrated to Israel from southern Arabia), 1 in 2,500 in the western portion of the ...
The MRI of patients with VWM shows a well defined leukodystrophy. These MRIs display reversal of signal intensity of the white matter in the brain. Recovery sequences and holes in the white matter are also visible. [4] Over time, the MRI is excellent at showing rarefaction and cystic degeneration of the white matter as it is replaced by fluid.
A series of cases with megalencephalic leukodystrophy were described by the Indian neurologist Bhim Sen Singhal (1933-)in 1991. [14] [11] [15] However, it is sometimes referred to as Van der Knaap disease after the Dutch neurologist Marjo van der Knaap who described another series of cases with clinical and radiological features in 1995. [16 ...
Over time, affected children experience mental impairment, worsening seizures and progressive loss of sight, speech and motor skills. Batten disease is a terminal disease; life expectancy varies depending on the type or variation. [7] [8] Females with juvenile Batten disease show first symptoms a year later than males, but on average die a year ...
Life expectancy may be shortened by respiratory complications arising from weakness of the muscles that aid breathing and swallowing. It was first described in four patients by Vucic and colleagues [ 3 ] working at the Massachusetts General Hospital in the United States ; subsequent reports from the United Kingdom, [ 4 ] Europe and Asia [ 5 ...
Alexander disease is a very rare autosomal dominant leukodystrophy, which are neurological conditions caused by anomalies in the myelin which protects nerve fibers in the brain. The most common type is the infantile form that usually begins during the first two years of life.
