阿尔兹海默症的现状
2017年8月29日北京
阿兹海默症(Alzheimer’s disease,AD)是一种不可逆、渐进性的脑部疾病,是最普遍的老人失智症。目前的药物治疗大多以缓解认知功能障碍和精神异常等为主,治标为主而不治本,AD 也没有具体的早期诊断方法,如何能早期发现、早期治疗也一直是学研医界努力的目标。
Dementia & Alzheimer's: They’re similar but not the same
Dementia & Alzheimer's: They’re similar but not the same
The terms dementia and Alzheimer’s are not interchangeable. The physical ailments the conditions cause (memory loss in particular) may seem similar. However the terms differ and are worth noting.
Dementia is not a specific disease. It’s an overall term that describes a wide range of symptoms associated with a decline in memory. It can also effect other thinking skills enough to reduce a person’s ability to perform everyday activities. Dementia is often incorrectly referred to as “senility” or “senile dementia”. The error reflects the widespread, incorrect belief that serious mental decline is a normal part of aging.
Alzheimer’s, however (also called Senile Dementia of the Alzheimer Type (SDAT) or simply Alzheimer’s) is a disease. It is the mon cause of dementia. The disease produces physical change in the brain. There is shrinking in some areas of the brain and widening in the others. This causes connections inside the brain to break and disrupt the brain’s electrical signals. Dementia can also be caused by a variety of other factors, but Alzheimer’s disease accounts for 50 to 80 percent of the cases.
Vascular dementia, which occurs after a stroke, is the second mon type. However, there are many other conditions that can cause symptoms of dementia. Some of these are reversible, such as thyroid problems and vitamin deficiencies.
Alzheimer’s is a progressive disease. The disease can be separated into three stages: early, middle, and late.
In the early stage, it is typical for a patient to forget words or misplace objects, forget something they just read, or ask the same question repeatedly. They also demonstrate difficulty with making plans and not remembering names when meeting new people.
