Treatments for dementia include improving memory, improving cognition, enhancing nursing care, and symptomatic treatment. 1. Improvement of memory. If the patient has obvious symptoms of memory loss, brain cell activation drugs can be taken orally to improve the patient’s memory, such as fenugreek, olanzapine and so on. 2. Improve cognitive ability. If the cognitive ability is obviously reduced, the cognitive ability can be improved by using lithopone methyl, donepezil and so on. 3. Strengthen nursing care. Patients with dementia lose the ability of daily life in the late stage, and it is necessary to strengthen nursing care to prolong the life. 4. Symptomatic treatment. Accompanied by severe insomnia can be used diazepam, lorazepam and so on. Antipsychotic drugs, such as olanzapine, should be used if there are obvious psychiatric symptoms. Dementia is recommended to be treated under the guidance of a doctor’s interview.
