Problems solved by technology

[0004] In recent years, cognitive dysfunction in patients with depression has attracted more and more attention from scholars at home and abroad. Studies have found that cognitive dysfunction in patients with depression may be independent of depressive symptoms, and some patients have impaired cognitive function. Improves with depressive symptoms, however, a significant proportion of patients suffer from cognitive impairment even when they are euthymic
In turn, impairment of cognitive function also hinders the recovery of psychological function, which in turn causes persistent difficulties in work, family, and social function
There are also studies that believe that after antidepressant treatment in elderly patients with cognitive impairment, some cognitive functions will be improved, but not necessarily to a normal level, especially memory and executive function, the development of elderly depression. Risk of developing progressive dementia may increase
