[Gerstmann's syndrome in a 9 year old boy]

Area of Science:

• Neuroscience
• Developmental Psychology
• Clinical Neurology

Background:

• Gerstmann's syndrome is characterized by finger agnosia, agraphia, acalculia, and right-left confusion, typically associated with left angular gyrus lesions.
• Its diagnostic value is debated due to varied underlying mechanisms for each component.
• The syndrome is rarely diagnosed in children due to the slow functional development of parietal lobes in early life.

Observation:

• A 9-year-old learning-disabled, right-handed boy presented with a clear diagnosis of Gerstmann's syndrome.
• Neuropsychological assessments confirmed acalculia, right-left disorientation, agraphia, and finger agnosia.
• No prior evidence of this dysfunction was noted at age 5.
• The patient had a history of perinatal asphyxia and neonatal seizures.
• Cranial CT and MRI revealed an infarcted lesion at the parietal-occipital lobe junction.

Findings:

• This case highlights the potential for Gerstmann's syndrome to develop in childhood following early neurological insults.
• The findings underscore the importance of comprehensive neuropsychological evaluation in children with learning disabilities and a history suggestive of brain injury.
• The lesion location at the parietal-occipital confluence correlates with the observed neurological deficits.

Implications:

• Early identification of Gerstmann's syndrome in children is critical for timely intervention.
• Specialized psychopedagogic supervision can mitigate the impact of associated learning disorders.
• This case contributes to understanding the later manifestation of Gerstmann's syndrome in pediatric populations.
