Abstract EN
Our objectives were to perform a longitudinal assessment of mental status in early stage Parkinson’s disease (PD) patients, with brief neuropsychological tests, in order to find predictive factors for cognitive decline.
Sixty-one, early stage, and nondemented patients were assessed twice, over a 2-year interval, with a global cognitive test (mini-mental state examination (MMSE)) and a frontal function test (frontal assessment battery (FAB)) and motor function scales.
Dementia and hallucinations were diagnosed according to the DSM-IV criteria.
Cognitive function scores did not decrease significantly, except for FAB lexical fluency score.
Four patients presented with dementia at followup.
The MMSE score below cut-off, worse gait dysfunction, the nontremor motor subtype, and hallucinations were significantly related to dementia.
Rigidity and speech dysfunction were related to dementia and a decrease in FAB scores.
We can conclude that decline in the MMSE and FAB scores is small and heterogeneous in the early stages of PD.
Scores below cut-off in the MMSE could be helpful to predict dementia.
Nontremor motor deficits could be predictive factors for frontal cognitive decline and dementia.
