The basic methods of treatment for cerebral atherosclerotic mental disorder and early vascular dementia are: 1. Improving cerebral circulation by appropriate activities 2. Regulating blood pressure, controlling high blood pressure and high blood sugar, which is the basic treatment. 3, improve cerebral blood circulation to increase cerebral blood flow and promote the establishment of collateral circulation. Low-molecular dextran, compound salvia injection and Chuanxiongzin are selected. 4. Hyperbaric oxygen therapy can greatly reduce the disability rate of cerebral infarction. It is suitable for early application. 5.The vasodilator dihydroergot alkaloids, 6.Cholinesterase inhibitors such as lithospermidine A and other drugs can be used. 7.Calcium channel blockers such as nimodipine and guilizine are used. 8.Anti-platelet aggregation agents such as aspirin or clopidogrel are used. This treatment can improve and slow down the progression of the disease. The presence of psychiatric symptoms can be treated symptomatically with antipsychotic drugs or antidepressants or anti-anxiety drugs. In general, the earlier the onset of treatment for cerebrovascular disease mental disorders, dementia, the better the results, too late treatment may not be very effective, especially in patients in the middle and late stages. In the case of Alzheimer’s disease, which is known as dementia, there are no specific drugs. For mild to moderate Alzheimer’s disease, you can take the cholinesterase inhibitor Donepezil tablets (Enrichment) 5mg per day at bedtime. 1 month is not effective, increase the dose to 10mg per day at bedtime. 3-6 months is a course of treatment, about one third effective, but not cured. Or Cabalatine tablets (Esnon), start with 1.5mg twice a day, and the maximum dose is 6mg twice a day. Or Staphylococcus aurantium tablets 0.1-0.2mg twice a day, the maximum daily dose should not exceed, 1-2 months a course of treatment. The glutamate receptor antagonist memantine tablets are recommended for the treatment of moderate to severe Alzheimer’s disease dementia at 10-20 mg per day. The current outcome of Alzheimer’s disease may not be very effective, especially in patients with intermediate to advanced stages. There is no specific treatment for advanced Alzheimer’s disease to bring the disease into remission, and the prognosis is poor, with an average of about 8-10 years from onset to death, but some patients can have the disease for more than 15 years, with rare spontaneous remission or self-resolution. Eventually, the disease develops into severe dementia, and death often occurs due to secondary physical diseases or failure such as bed sores, fractures, pneumonia, and malnutrition. Therapies such as hormone therapy and stem cell transplantation currently do not treat this disease. The presence of psychiatric symptoms can be treated symptomatically with antipsychotic drugs or antidepressants or anti-anxiety drugs. Patients with advanced dementia often have to be cared for as much as, or even more difficult than, caring for a small child.
