OBJECTIVE: The aim of this study was to investigate whether specific neuropsychiatric domains could predict a conversion to dementia in those patients either with amnestic subtype of mild MCI (aMCI) or subcortical vascular MCI (svMCI).

METHODS: At baseline, all subjects underwent neuropsychological tests, Neuropsychiatric Inventory (NPI), and MRI. We compared the baseline NPI scores between converters (CV) and non-converters (NCV) both in the aMCI and svMCI groups.

RESULTS: The mean follow-up duration was 16.74±8.02 months (range: 4.2-43.9). At the second time point, about 30% of aMCI and svMCI patients converted to dementia with 7.5% of aMCI patients exhibiting improvement to normal cognitive state. In female aMCI patients, those who later improved to normal cognition exhibited higher baseline depression scores than the CV group. However, baseline depression scores were higher in the CV group than the NCV group in svMCI patients, and this difference was significant only in males.

CONCLUSION: Our results suggest that depression might serve as a predictive marker of conversion to dementia in patients with svMCI, albeit only in males. On the other hand, patients who later improved to normal cognition showed higher scores of depression at baseline in female aMCI patients, suggesting that longer follow-ups are warranted in female patients with aMCI and depression.
