Depressive symptoms in patients admitted to a semi-intensive stroke unit.

Aim of this study was to evaluate depressive symptoms in a semi-intensive Stroke Unit (SI-SU) by a scale specifically devised to assess depression in patients with stroke and to identify the symptoms better contributing to the early detection of post stroke depression (PSD). Fifty-four patients admitted to a SI-SU because of suffering from single, first-ever hemispheric stroke were enrolled. Depressive symptoms were assessed by the Post Stroke Depression Rating Scale (PSDRS). All patients were also evaluated by the National Institute of Health Stroke Scale (NIHSS), the modified Rankin scale, the Mini-Mental State Examination (MMSE) and the Frontal Assessment Battery (FAB). The PSDRS detected depressive symptoms in twenty-two patients (40%). The PSDRS scores were not influenced by severity of stroke, functional outcome, site of lesion and type of stroke. Three psychopathological factors were identified inside the PSDRS: "reactivity", "melancholic" and "apathetic", with significant inverse correlations with cognitive measures found only with the "apathetic" factor Less than one-half items of the PSDRS were able to identify overt depressive symptoms. Depressive symptoms are a frequent and early complication in patients referred to a SI-SU with the PSDRS being a suitable tool to detect depressive symptoms in acute phases of stroke.
