1. What is the difference between and dementia?
Alzheimer's disease is a type of dementia. Dementia is a loss of thinking, memory and reasoning ability that can interfere with a person's daily life and activities. Alzheimer's disease is the most common cause of Alzheimer's disease. Other types of dementia include frontotemporal lobe disease, Lewy body dementia and vascular dementia .
Simply put, the scope of dementia described is greater than that of Alzheimer's disease.

2. What are the early symptoms of Alzheimer's disease?
Memory problems are usually one of the first signs of Alzheimer's disease, although different people may have different initial symptoms. Declining other aspects of thinking, such as not finding the right words, visual/spatial problems, and impaired reasoning or judgment, may also herald the early stages of Alzheimer's disease.
Minor cognitive impairment (MCI) is a disease that may also be an early sign of Alzheimer’s disease – but not everyone with MCI will suffer from Alzheimer’s disease. In addition to memory problems, motor difficulties and olfactory problems are also associated with MCI. If you have an MCI, be sure to see a doctor or specialist regularly to monitor any changes in memory or thinking.

3. What are the stages of Alzheimer's disease?
Alzheimer's disease is divided into several stages: preclinical, early, middle and late stages. During the preclinical stage of Alzheimer's disease, people appear to have no symptoms, but a buildup of pathological substances is happening in the brain.
As Alzheimer's disease progresses to the medium stage, memory loss and confusion will become more severe, and people may not be able to identify family and friends. As Alzheimer's disease becomes worse, people lose their ability to communicate. They may sleep more, lose weight, dysphagia . In the end, I cannot take care of myself and need comprehensive care.

4. What is the cause of Alzheimer's disease?
Scientists have not fully understood what causes Alzheimer's disease in most people. There may be genetic factors in early onset Alzheimer's disease that occurs between the 30s and 60s. Late-onset Alzheimer's disease usually develops in a person's 60s and is caused by a series of complex age-related brain changes that have occurred over decades. Causes may include genetic, environmental, and lifestyle factors. These factors have different effects on everyone.
5 caused by a series of complex age-related brain changes that have occurred over the past decades. Is Alzheimer's disease inherited?
Just because a family member has Alzheimer's disease does not mean that you are at a high risk of dementia. However, if more people in the family members suffer from dementia, it will undoubtedly increase a person's risk of late-onset Alzheimer's disease.
Rare premature onset Alzheimer's disease may be caused by mutations or changes in certain genes. If one of the mutations in one of these genes is inherited, the child will usually — but not always — have the disease. But this premature-onset dementia is rare.
6. Is there a cure for Alzheimer's disease?
At present, there is no cure for Alzheimer's disease. Currently, the Food and Drug Administration (FDA) has approved only a few drugs for treating Alzheimer's disease patients. Some drugs and interventions may help control behavioral symptoms, but do not help cure the disease. The latest drug, aduzumab, is still in clinical trials despite passing FDA pre-approval. Hope there is, but you still need to wait patiently.
7. Is there a way to prevent Alzheimer's disease?
At present, there is no clear evidence of what can prevent Alzheimer's disease or age-related cognitive decline.What we know is that a healthy lifestyle—including a healthy diet, physical exercise, proper weight and controlling hypertension —can reduce risks.
There are 12 mutable risk factors for that are supported by literature evidence: including low education, hypertension, hearing impairment, smoking, obesity, depression, lack of exercise, diabetes and less social contact (2019 version) , excessive drinking, traumatic brain injury and air pollution (newly added in 2020 version) . These 12 variable risk factors, together accounting for about 40% of global dementia, can fundamentally prevent or delay the occurrence of dementia.
