Firstly, attention must be paid to pharmacological treatment. In terms of pharmacological therapy, the main treatments include cholinesterase inhibitors, which can increase the amount of acetylcholine in the central nervous system and improve the patient’s cognitive level. Glutamate receptor antagonists can also be used, and they have a certain therapeutic effect on moderate to severe dementia. Secondly, patients with dementia may exhibit psychiatric symptoms in the later stages, such as hallucinations. Under a doctor's advice, appropriate amounts of antipsychotic drugs can be used for treatment. Thirdly, medications that protect brain cells and nourish nerves can be administered to the elderly. Additionally, close nursing care is necessary to prevent accidents. (Please undertake medication under the guidance of a professional physician.)
