For patients with dementia, if the diagnosis is confirmed, the recommended treatment is as follows: First, it is very important to pay attention to nursing care. Patients with dementia often get lost, which can lead to a series of dangers, so it is necessary to take good care of them to prevent getting lost. Secondly, for the improvement of cognitive functions, it is recommended to use some cholinesterase inhibitors, which can increase the level of acetylcholine in the brain and improve the patient's cognitive functions to a certain extent. Third, symptomatic treatment should also be provided. Since patients with dementia often exhibit psychiatric symptoms, such as visual and auditory hallucinations, appropriate antipsychotic medications can be used for treatment. (Please use medication under the guidance of a professional physician.)
