Depression in patients with cerebral microangiopathy

Abstract

Cerebral microangiopathy (CMA) is one of the significant causes of depression in the elderly. Close associations of the risk of developing depression with white matter hyperintensity, the presence of lacunar infarcts, and other markers of vascular disease are shown. The available data suggest that various vascular mechanisms, in particular, involvement of small vessels of the brain, generalized microvascular and endothelial dysfunction, metabolic risk factors, – are risk factors for the development of depression. Pathogenetic mechanisms include cerebral hypoperfusion and immune dysregulation. Depression is also a common complication of coronavirus infection, occurring both in the acute and postCOVID periods. The same mechanisms as in vascular depression are involved in the pathogenesis of the development of post-COVID depressive disorders. Given the complexity of the mechanisms of development of depressive disorders in patients with CMA, the presence of severe comorbid vascular pathology, antidepressants with an optimal ratio of efficacy and safety should be preferred. Agomelatine (Valdoxan) is one of such drugs.
