First, elderly patients with depression need special care. It is better to have relatives. If relatives are busy at work, they can also ask someone to take care of them. In short, they shouldn't leave people for 24 hours. Nurses learn relevant health knowledge, understand patients' situation and master corresponding nursing skills.

Second, master the daily life of the elderly. Live a regular life, go to bed early and get up early, arrange outdoor activities for a period of time every day if possible, pay attention to climate change and actively prevent complications.

Third, we should pay attention to a balanced diet. Eat more foods rich in protein and vitamins, such as milk, eggs, lean meat, bean products, fruits and vegetables, and eat less sugar and starch.

Fourth, pay attention to mental health. Good at observation. From the subtle emotional changes of the old man, we can find his ambivalence and conflict, and make some psychological explanations, comfort and encouragement in a targeted manner.

Fifth, insist on taking medicine. Pay attention to the possible adverse reactions, that is, be patient, strictly follow the doctor's advice, do not add or subtract drugs at will, and report to the doctor as soon as possible if there is any situation. Sixth, prevent accidents. Because such patients often try to commit suicide, they should not be negligent and do some related preventive work.
