Alexander's disease: unique presentation

Area of Science:

• Neuroscience
• Metabolic Disorders
• Genetics

Background:

• Subacute necrotizing encephalomyelopathy (Leigh syndrome) is a complex neurological disorder characterized by lactic acidosis and diverse clinical and pathological findings.
• While metabolic abnormalities are often associated with Leigh syndrome, many cases lack an identified metabolic defect.

Observation:

• A patient presented with clinical, metabolic, and neuroradiological features suggestive of Leigh syndrome.
• Unusual ocular motility abnormalities were noted in the patient.
• Neuropathological examination revealed the definitive diagnosis to be Alexander's disease.

Findings:

• The patient's presentation mimicked Leigh syndrome, including metabolic derangements and neurological symptoms.
• Alexander's disease was confirmed neuropathologically, a diagnosis not typically associated with the observed metabolic profile.
• This case represents a unique presentation of Alexander's disease with Leigh syndrome-like metabolic and clinical features.

Implications:

• This case highlights the importance of neuropathological confirmation for definitive diagnosis in complex neurological disorders.
• The findings expand the known clinical and metabolic spectrum of Alexander's disease.
• Further research may elucidate shared pathways or diagnostic challenges between Leigh syndrome and Alexander's disease.
