People are prone to psychological problems when they enter old age, especially after retirement. Especially some career-oriented people, who are workaholics before retirement and do not have many hobbies of their own, do not know how to live once they retire and are bored to the point of insomnia, early awakening, no interest in anything, and next they start to be depressed. Experts point out that when the elderly are about to retire, they should plan their post-retirement life in advance, participate in more community activities, establish new interpersonal circles and so on, to prevent depression in old age. One, do not think that the elderly depressed is normal Most people do not know much about depression, often think that “people are old, it will be like this”, and ignore the existence of mental illness. According to the survey, about 20% of diabetic patients have subclinical depressive symptoms, if the “unhappiness” is short-lived and mild, it is possible that the patient can recover on his or her own. If the depression persists (more than two weeks) and is more serious, making the patient feel pain or affecting his life and social interaction, it should be considered a psychiatric disease, and the elderly should be taken to the hospital for treatment in a timely manner, instead of letting it develop or ignoring it. Second, in the face of depression, what should the elderly children do? 1.Psychological care As depressed patients often lack self-confidence, pessimism and even despair, children should talk more with the patients, give more help and encouragement in life, and help them to build up confidence in life. 2.Close observation Children should strengthen observation, pay attention to the emotional changes of depressed patients and prevent them from committing suicide and self-injury. 3.Supervise the use of medication Patients should be supervised to use medication, especially those who are recovering from the disease, never stop medication just after the disease. Randomly stopping the medication will increase the chance of relapse, stopping the medication or not should be done under the guidance of the doctor. 4, life care Pay attention to the patient’s diet, to ensure adequate sleep. For those who are less ill, they should be encouraged to go out more often and do what they can and participate in relaxing activities, such as listening to music, playing chess, dancing, raising birds and fish, etc. 5.Encourage socialization Encourage depressed patients to return to the social circle of friends and relatives to receive the infection of others’ happiness, the power of this social support is very important for their recovery.
