Dépression post-accident vasculaire cérébral chez les patients hospitalisés à N’Djaména

Introduction: Depression is the most common psychiatric complication after stroke, with a worldwide prevalence estimated at 18–60%. It nevertheless remains under-recognised and under-diagnosed in our setting, where no epidemiological data are available. Methods: We conducted a 6-month prospective study (1 November 2025 – 1 May 2026) of patients hospitalised for stroke in the Neurology Department of the National General Reference Hospital (HGRN), N’Djamena. Depression was assessed with the MADRS (threshold > 20). Results: Of 98 patients, 33 had post-stroke depression (PSD), a prevalence of 33.67%. The mean age of depressed patients was 58.51 ± 13.71 years (range: 30–84 years) and 57.58% were male. The prevalence of depression was 38.71% among married patients. At 3 months, 6 depressed patients (18%) had a favourable outcome under treatment. Conclusion: Post-stroke depression is common and affects both functional and vital prognosis. Further studies are needed to better understand its determinants and to open the way to new therapeutic interventions.
