Inherited white matter disorders in Japan: focusing on demyelinating leukodystrophy

Area of Science:

• Neurology
• Genetics
• Pediatrics

Background:

• Inherited cerebral white matter disorders are a group of rare, progressive neurological conditions affecting children.
• These disorders impact myelin development and maintenance, leading to significant disability.

Purpose of the Study:

• To review key inherited cerebral white matter disorders affecting children.
• To discuss the causes, symptoms, diagnostic imaging, and current treatment strategies for these rare diseases.

Main Methods:

• Systematic review of published literature on representative inherited white matter disorders.
• Categorization of disorders into demyelinating, astrocytic, and water homeostasis abnormalities.

Main Results:

• The review details adrenoleukodystrophy, Krabbe disease, metachromatic leukodystrophy, Alexander disease, vanishing white matter disease, megalencephalic leukoencephalopathy with subcortical cysts, and CLCN2-related leukoencephalopathy.
• Causes, symptoms, diagnostic imaging, and forefront treatments for each disorder were discussed.

Conclusions:

• Despite the rarity and small analyzed case numbers, effective radical treatments for these progressive white matter disorders are essential.
• Future research and therapeutic advancements are crucial for complete patient recovery.
