Treatment of depression in the elderly: The first one is pharmacotherapy. It is recommended to use new antidepressants, such as selective pentothal reuptake inhibitors, such as paroxetine, citalopram, escitalopram, sertraline, fluoxetine, etc. The somatic side effects of this class of drugs are relatively minor and may occasionally affect the appetite of the elderly. Some patients may also suffer from insomnia or drowsiness, which can be relieved by taking drugs to promote digestion and appetite, or by taking benzodiazepine anxiolytics. As treatment proceeds, the adverse effects will slowly ease or even disappear, and the antidepressant effects will slowly emerge. The starting dose of medication for depression in the elderly should be small and the dosage should be increased slowly, and the response of the elderly should be closely observed. The second treatment method is psychotherapy, which is mostly supportive psychotherapy, that is, more communication with the elderly, respect, care and comfort, encourage the elderly to express and vent their bad emotions, and also help the elderly to deal with difficulties in life, such as interpersonal problems and self-worth problems. Because the ability of the elderly to comprehend and change will decline with age, cognitive therapy, behavioral therapy or psychoanalysis is not performed.
