Post-stroke depression.
Post-stroke depression (PSD) is among the most common emotional disorders afflicting stroke sufferers. Approximately one third of stroke survivors experience an early or later onset of depression. PSD impedes the rehabilitation and recovery process, jeopardizes quality of life and increases mortality. Diagnosis of PSD is challenging in the acute and chronic aftermath. Therefore, it often remains unrecognized and/or undertreated. The interaction between depression and stroke is very complex and the pathophysiological mechanisms have not as yet been fully elucidated, although an interaction between anatomical and psychosocial factors may be important in PSD development. Neurochemical changes and clinical findings are similar to endogenous depression. PSD is potentially treatable, although no conclusive benefits of antidepressant agents and nonpharmacological interventions have been observed. The efficacy of preventive strategies in PSD remains essentially undetermined.
