Depression is a frequent psychiatric complication after a stroke. In a Sub-Saharan Africa, the majority of the studies are about their prevalence, but the incidence of post-stroke depression was rarely estimated. We aimed to estimate this incidence in Parakou, Benin. We had conducted a dynamic cohort study with 203 stroke patients in the department of neurology of the university hospital in Parakou. Patients with a history of depression were excluded. Patients were followed during a period of 21 months from January 1, 2013 to September 30, 2014. Depression was defined according to the criteria of DSM-IV. They were 18 to 99 years old with an average age of 58.4±14.2 years. In average, consultation was made 54.3h±112.9h after onset symptoms. Concerning the type of stroke, 45.8% were ischemic, 31% hemorrhagic and 23.2% were indeterminate. The cumulative incidence of depression was 30%. The incidence rate of depression was 18.5 per 100 person-years. The factors associated with the occurrence of depression were initial coma, initial severity of stroke, disability and history of diabetes. The incidence of depression remains very high and must be evaluated. Considering the associated factors of depression in post-stroke and including them among the management strategies could reduce overall burden.
