[Neurodegeneration with brain iron accumulation]

Area of Science:

• Neurology
• Genetics
• Radiology

Background:

• Neurodegeneration with brain iron accumulation (NBIA) is a complex group of rare neurological disorders characterized by progressive neurodegeneration and iron deposition in the brain.
• While NBIA1 (pantothenate kinase-associated neurodegeneration) has been recognized for a century, other NBIA subtypes, including NBIA4, are more recently identified, presenting diagnostic challenges.

Observation:

• A 16-year-old male presented with neurodegenerative symptoms that began at age eight.
• The patient exhibited typical magnetic resonance imaging (MRI) findings indicative of iron accumulation in the basal ganglia, a hallmark of NBIA.

Findings:

• The diagnostic process involved detailed gait analysis to assess motor function and specific genetic testing to confirm the subtype of NBIA.
• The patient was diagnosed with NBIA4, underscoring the importance of advanced diagnostic tools for rare neurodegenerative conditions.

Implications:

• This case emphasizes the diagnostic utility of MRI in identifying basal ganglia iron deposition, crucial for NBIA diagnosis.
• The integration of gait analysis and genetic testing is vital for accurate subtyping and understanding the heterogeneity of NBIA syndromes.
• Early and precise diagnosis of NBIA4 facilitates appropriate patient management and contributes to the broader understanding of neurodegenerative diseases.
