The relation between cognitive impairment and clinical presentation in early stages of Parkinson’s disease

Objective: we studied patients in early stage of Parkinson’s disease (PD), after the onset of first motor signs of disease. We evaluated if any cognitive function were affected and if there was a link between such impairment and clinical and imagistic data. Material and Methods: 30 patients previously diagnosed with PD stage I and II were evaluated with COGTEST software. Conclusion: the research concluded that, even if cognitive impairment was detected in patients with tremor, significant deficits of attention, executive function and working memory were found in subjects with excessive rigidity.
