The emergence of PSD can lead to adverse emotional experiences for patients and also affect rehabilitation outcomes. Due to the relatively hidden occurrence of post stroke depression and the presence of post stroke language disorders in some patients, the treatment of post stroke depression is more difficult. The lower concentration of 5-HT in the intercellular space of the brain is associated with depression. The raphe nuclei contains serotonergic neurons whose main function is to produce 5-HT. The activation of serotonin neurons has an inhibitory effect on depression. For patients with post-stroke depression, the combination of acupuncture and medical treatment can effectively reduce the incidence of post-stroke depression on the basis of traditional treatment methods. With the establishment of the "biological psychological social" medical model, the mechanism of post stroke depression has begun to be addressed through humanized thinking. Pay more attention to the quality of life of patients with post-stroke depression. It is particularly important to seek more systematic treatment for post-stroke depression. Therefore, it is necessary to study the treatment mechanism of post stroke depression (PSD).
