What are axonal spheroids?
Another feature of ALSP is swellings called spheroids in the axons of the brain, which are a sign of axon damage. Also common in ALSP are abnormally pigmented glial cells. Glial cells are specialized brain cells that protect and maintain neurons.
Is leukoencephalopathy hereditary?
Background Hereditary diffuse leukoencephalopathy with neuroaxonal spheroids (HDLS) is a hereditary, adult onset leukodystrophy which is characterised by the presence of axonal loss, axonal spheroids and variably present pigmented macrophages on pathological examination.
What is HDLS disease?
Summary. Listen. Hereditary diffuse leukoencephalopathy with spheroids (HDLS) is a neurological condition characterized by changes to certain areas of the brain. A hallmark of HDLS is leukoencephalopathy, which is damage to a type of brain tissue called white matter.
What is pigmented glia?
Abstract. Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is a rare white matter degenerative disease characterized by both axonal and glial injury due to a defect in the CSF1R gene.
When does Wallerian degeneration occur?
Wallerian degeneration is an active process of retrograde degeneration of the distal end of an axon that is a result of a nerve lesion. It occurs between 7 to 21 days after the lesion occurs.
Is leukoencephalopathy curable?
No treatment for progressive multifocal leukoencephalopathy has proved effective. However, if the disorder that has weakened the immune system is treated, people survive longer.
What are the symptoms of leukoencephalopathy?
Symptoms
- Clumsiness or loss of coordination.
- Difficulty walking.
- Facial drooping.
- Loss of vision.
- Personality changes.
- Trouble speaking.
- Weak muscles.
How long does Wallerian degeneration last?
Wallerian degeneration. Loss of axonal continuity due to an axotomy lesion causes breakdown of the distal axon over a period of 3–5 days.
What part of the brain does leukoencephalopathy affect?
Progressive multifocal leukoencephalopathy (PML) is a rare brain infection. It affects the substance in your brain that protects nerve cells. PML gets worse over time and may lead to neurological disabilities. Timely treatment may slow disease progression.
Can leukoencephalopathy be cured?
Treatment. The best way to treat PML is to fight whatever has made your immune system weak. You might take drugs that attack the virus that causes AIDS (HIV) or avoid drugs that affect your immune system. You also might need to avoid treatments like chemotherapy, which can put you at higher risk of infections.
