- Abstract
Introduction: We showed that the Clock Drawing Test (CDT) performed during the acute phase of cerebrovascular diseases predicted worsening of cognitive function defined based on a clinical judgement at a 3-month follow-up. The aim of this study was to verify the predictivity of the CDT on the worsening of cognitive status assessed with an extensive neuropsychological evaluation 6 months after the acute event. Methods: Patients with a stroke or transient ischemic attack underwent a baseline clinical, neuroimaging, and neuropsychological assessment, including the CDT. Premorbid cognitive status was evaluated by means of the Clinical Dementia Rating scale. Between 6 and 7 months after the acute event, all patients underwent a neuropsychological evaluation that included tests for executive function, attention, language, memory, and visuospatial abilities. Results: Fifty patients (29 males; mean age 72.2 years) were enrolled: 28 (56%) had no premorbid cognitive impairment, 15 (30%) had premorbid mild cognitive impairment (MCI), and 4 (8%) had premorbid dementia; for 3 patients, evaluation of premorbid status was not available. At follow-up, 11 (22%) had no cognitive impairment, 28 (56%) were diagnosed with MCI, and 11 (22%) dementia. In patients who were non-demented before the event, on regression analysis, the score obtained at CDT was predictive of decline of cognitive status at the 6-month follow-up (OR 1.65; 95% CI 1.08–2.52). Discussion: Our study confirms that administering the CDT during the acute phase of cerebrovascular diseases is informative with regard to the worsening of cognitive function after 6 months.
