Abstract
The aim of the present study was to investigate the relationships between poststroke depression (PSD), lesion location and cognitive deficits after stroke. We studied 20 patients within the first month after clinical onset (T1), and one year later (T2). PSD was observed in 55% of patients at T1 and 35% of patients at T2. At T1, depression was reliably correlated with dorsal lesions in the right-hemisphere and anterior lesions in the left hemisphere. Lesion location was no longer a significant factor determining PSD at T2. Changes in PSD, from T1 to T2, were inversely correlated with the performances in cognitive tests exploring the domains of attention, visuospatial learning, executive/motor functions, and with the global composite cognitive score. Our data suggest that: 1) in the mix of influences that may produce PSD, lesion location is the main factor determining mood changes after stroke in the first month; 2) PSD produces deficits in attention, learning, and executive/motor functions, without affecting language and other cognitive domains.
Sommario
Scopo di questo studio sono i rapporti tra la depressione post-stroke (PSD), la localizzazione della lesione cerebrovascolare e i disturbi cognitivi conseguenti alla lesione. Abbiamo studiato 20 pazienti entro il primo mese dall'episodio ictale (T1) ed un anno dopo (T2). La PSD era osservabile nel 55% dei pazienti a T1 e nel 35% dei pazienti a T2. A T1, la PSD era significativamente correlata con lesioni dorsali nell'emisfero di destra e con lesioni anteriori nell'emisfero di sinistra. Queste correlazioni non erano più significative a T2. Le variazioni della PSD da T1 a T2 erano inversamente correlate con le prestazioni dei pazienti a compiti cognitivi di attenzione, apprendimento visuospaziale, funzioni esecutivo/motorie, e con un punteggio cognitivo composito.
Questi dati suggeriscono che: 1) tra le numerose cause che possono produrre la PSD, la localizzazione della lesione sembra essere il fattore principale nel primo mese dopo l'episodio cerebrovascolare; 2) la PSD produce disturbi attentivi, di apprendimento visuospaziale ed esecutivi/motori senza determinare disturbi nella sfera del linguaggio e di altre funzioni cognitive.
