13-year, 9-month-old biracial female with no prior medical history presented with a new onset neurodegenerative disorder following a bullying incident. This case highlights the role of neuropsychology in the characterization of neurodegenerative disorders in a pediatric population. Patient presented with 4-week history of progressive ataxia, nystagmus, and poor memory. Concern for anoxic brain injury from the bullying led to an MRI showing T2 hyperintensity in the bilateral cerebellar peduncles, pons, and midbrain with a "hot cross bun" sign. A deletion in the EPRS gene was found, known to cause hypomyelinating leukodystrophy 15; however, this mutation was not thought to explain her condition. She was diagnosed with a neurodegenerative disorder, type unknown, and severe expressive language disorder. Educational evaluation (age 8) showed low average to average cognitive functioning. Current testing showed intact effort with impaired cognitive functioning and bilateral speeded fine motor dexterity. Expressive and receptive language skills were below average to impaired; speech was slowed and dysarthric. Verbal memory was impaired, but visual memory and executive functioning testing were intact. Parent ratings indicated below average to impaired adaptive functioning. Patient received therapy for the bullying trauma and exhibited no trauma symptoms at this evaluation. Despite the unclear diagnosis, this patient experienced a significant decline in motor and speech/expressive language skills due to an unidentified neurodegenerative disorder. Neuropsychological evaluation also confirmed impacts on intelligence and receptive language and ruled out trauma and psychiatric contributions. This case highlights the role of neuropsychology in multidisciplinary work-up of an unidentified neurodegenerative condition.
