How To Prevent Alzheimer's Disease

What is Alzheimer's disease? 

Alzheimer's disease is a common neurodegenerative disease, with a general onset age of over 65 years old. Very few people develop the disease before the age of 65. Taking the age of 65 as the boundary, those that appear after the age of 65 are called late-onset Alzheimer's disease, and those that appear before the age of 65 are called early-onset Alzheimer's disease. Early-onset Alzheimer's is relatively rare, and it is largely influenced by genetics. This answer is about late-onset Alzheimer's after age 65, not the rare early-onset form.

How do you know if you or someone around you has Alzheimer's?

Currently, diagnosing Alzheimer's requires a professional with a nationally licensed physician. You can find physicians specializing in this field in neurology or geriatric medicine in a tertiary hospital.

Due to the similar symptoms of cognitive impairment in Alzheimer's and aging, it is difficult to diagnose, so physicians may need to investigate through a variety of examination methods. When you and the elderly seek medical treatment, please be patient with the process. The more inspection methods, the more accurate the diagnosis will be able to help doctors.

When visiting a doctor, you may encounter the following inspection methods:

(1) Neuropsychological examination: The short intelligence test MMSE is the most common one, which can assess the degree of cognitive impairment in the elderly. But its limitation is that the recognition rate of early Alzheimer's is not high enough to distinguish Alzheimer's from other types of dementia.

(2) Talking with family members: Since the patient is usually not aware of his own abnormality, his primary caregiver or family member can provide a lot of valuable information. Therefore, intentional attention to the behavior of the elderly, especially the changes in memory, speech expression, emotional management, reading, and writing, will help doctors make a better diagnosis.

(3) Marker examination: Some marker examinations of blood, cerebrospinal fluid, urine, etc. can be used as auxiliary indicators for the diagnosis of Alzheimer's disease. In addition, doctors will investigate other diseases based on the patient's past history and chief complaints.

(4) Imaging: Magnetic resonance imaging (MRI), positron tomography (PET) and other medical imaging methods can more intuitively help doctors investigate other brain lesions. It should be reminded that some hospitals do not have the conditions to use imaging, and the cost of testing is relatively high.

Diagnosis may be misdiagnosed and missed. In order to ensure the accuracy and reliability of the diagnosis, you can be more patient and go to different hospitals for multiple diagnoses.

Can Alzheimer's be cured?

Unfortunately, as mentioned earlier, Alzheimer's cannot be completely cured at present, but there are still drugs for treatment. In foreign countries, several drugs have been proven to reduce cognitive impairment in Alzheimer's patients within a certain period of time. For example, there are two types of drugs approved by the U.S. Food and Drug Administration (FDA), one is a cholinesterase inhibitor and the other is memantine. Both classes of drugs can improve symptoms of cognitive impairment in patients, such as memory impairment and reasoning abilities. However, the brain's neuron cells and the connections between neurons can be damaged by this disease. This damage is medically irreversible. At this stage, we cannot cure this. These medicines, which improve symptoms, work within a certain period of time. But whether they can completely stop the progression of Alzheimer's disease remains controversial. While an effective cure has yet to be found, humanity will not stop. As of today, in China, among the public information on the drug and clinical trial registration and information publicity platform, 31 projects are in the stage of new drug clinical trials, and 26 drugs have been completed. Clinical Trials. Since 2019 alone, five drugs have entered clinical trials. Internationally, among the clinical trials published on http://clinicaltrials.gov, 199 new drugs are undergoing clinical trials. Technology is accelerating and people's life expectancy is increasing. I believe you can witness the day when a cure for Alzheimer's disease is developed.

What is the natural herb for Alzheimer's disease?

Cistanche can increase the protein expression levels of nicotinic acetylcholine receptor (nAChR) α3 and α7 receptor subunits in SH-SY5Y cells, and resist the levels of α3 and α7 receptor subunits caused by Aβ25-35 The reduction of Aβ can reduce the cell damage and the increase of lipid peroxidation level caused by Aβ; it can also promote the axon growth of pheochromocytoma (PC12) cells in patients with Alzheimer's disease, and increase the brain of patients with Alzheimer's disease. The level of nerve growth factor (NGF) in glioma (Giiomas, C6) cells, as well as the hippocampal axon growth, neuronal differentiation, and synapse formation in the hippocampus of patients with Alzheimer’s disease, can stimulate Alzheimer's The secretion of NGF in the cerebral cortex and hippocampus of patients with Alzheimer's disease significantly improves the learning and memory ability of patients with Alzheimer's disease. These effects show that the Chinese medicine Cistanche is an excellent product for treating Alzheimer's disease.
