[Frontotemporal dementia in metachromatic leukodystrophy]

Area of Science:

• Neurology
• Neurodegenerative Diseases
• Genetics

Background:

• Metachromatic leukodystrophy (MLD) is a rare genetic disorder.
• It typically affects the white matter of the nervous system.
• MLD is characterized by arylsulfatase A deficiency, leading to sulfatide accumulation.

Observation:

• A 39-year-old woman presented with frontotemporal dementia symptoms.
• Clinical examination revealed no signs of polyneuropathy.
• This atypical presentation challenged initial diagnostic considerations.

Findings:

• The patient's neurological presentation mimicked frontotemporal dementia.
• Absence of polyneuropathy is an unusual feature for MLD.
• This case highlights the diverse clinical spectrum of MLD.

Implications:

• Frontotemporal dementia diagnosis should prompt consideration of MLD.
• Early identification of MLD is critical for potential therapeutic strategies.
• Recognizing atypical MLD presentations improves diagnostic accuracy and patient outcomes.
