    Elevated cerebrospinal fluid levels of DOPA decarboxylase may aid in diagnosing Lewy body disorders like Parkinson's disease and dementia with Lewy bodies.

  • 2

    CSF DDC concentrations were significantly higher in Lewy body disorders compared to cognitively healthy controls and Alzheimer’s disease.

  • 3

    Models using CSF DDC, age, and sex showed strong diagnostic performance for distinguishing Lewy body disorders from other conditions.

  • 4

    Higher CSF DDC levels correlated with specific clinical features in dementia with Lewy bodies, such as parkinsonian symptoms and visual hallucinations.

  • 5

    The study suggests CSF DDC may reflect dopaminergic neuronal dysfunction, but further research is needed to confirm its diagnostic utility.
