Uncommon yet impactful - case-based reflections on rare neurologic disorders

Area of Science:

• Neurology
• Genetics
• Rare Diseases

Background:

• Rare diseases collectively affect millions globally, posing diagnostic challenges, especially in neurology.
• Overlapping symptoms and limited awareness often delay recognition and management of rare neurologic disorders.

Purpose of the Study:

• To highlight diagnostic and therapeutic complexities in rare neurologic disorders.
• To emphasize the importance of timely and accurate diagnosis for patient outcomes.

Main Methods:

• Presentation of three illustrative case studies of rare neurologic disorders.
• Detailed analysis of diagnostic pathways, genetic findings, and therapeutic interventions.

Main Results:

• Case 1: CSF1R-related disorder diagnosis delayed by misattribution to traumatic brain injury, missing timely intervention.
• Case 2: MAPT gene variant (pallidopontonigral degeneration) diagnosed early due to family history, highlighting hereditary disease management challenges.
• Case 3: Concurrent spinocerebellar ataxia types 3 and 8 due to dual mutations, showcasing clinical ambiguity from co-occurring rare variants.

Conclusions:

• Accurate and timely diagnosis is vital to prevent unnecessary testing and guide personalized therapies for rare neurologic diseases.
• Early recognition facilitates access to emerging treatments and support systems for patients with rare neurologic conditions.
