This study presents a unique case of developmental colour agnosia, a rare condition where individuals cannot recognize colors. The patient

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Clinical Neurology

Background:

  • Colour agnosia is the inability to recognize colors despite intact color perception, memory, and naming abilities.
  • Previous cases of selective colour agnosia have been linked to left hemisphere damage.

Observation:

  • A 43-year-old man presented with a stroke in his right cerebellar hemisphere.
  • During assessment, the patient demonstrated an inability to name colored patches, indicating selective colour agnosia.

Findings:

  • Detailed assessment confirmed selective colour agnosia in the patient.
  • The patient reported this deficit since birth, predating the stroke.
  • The cerebellar infarct was in an area not typically associated with color processing, suggesting a developmental origin.

Implications:

  • This case suggests that developmental colour agnosia can occur independently of typical left-hemisphere color processing areas.
  • It highlights the potential role of cerebellar structures in color recognition or the possibility of alternative processing pathways.
  • This finding expands our understanding of the neural basis of color agnosia and its developmental forms.
