Great breakthrough in medicine! Blood test can detect early Alzheimer's disease, so if you want to see if you have Alzheimer's disease, you only need to pass a simple blood test.
The University of Melbourne, Australia, and many universities in Japan jointly use a high sensitivity mass spectrometry analysis technology to detect beta amyloid protein content in blood samples, which can detect Alzheimer's disease in the early stage. The accuracy rate can reach 90%. The cost is low, the accuracy is high, the operation is convenient and fast, and it will not cause trauma to patients. In the future, it is expected to become a routine examination method for screening and diagnosis of this disease.
Alzheimer's disease, commonly known as Alzheimer's disease, was generally over 65 years old in the past. At present, the incidence of Alzheimer's disease is younger. Many diseases that were thought to be acquired only when they are old are also common among young people. Medical experts pointed out that poor diet, sedentary and other lifestyles are important factors leading to the younger disease.
Ten omens of Alzheimer's disease must be prevented
1. Memory disorder
It mainly occurs in the early stage, especially near memory disorder, that is, what happened dozens of hours or even minutes ago cannot be recalled. The patient's daily life is characterized by 'forgetting things in three aspects' and' forgetting after finishing ', asking questions or telling the same things repeatedly.
2. Language barrier
The difficulty in finding words is often the first language barrier in Alzheimer's disease, which is mainly manifested in the inability to find the right words when speaking. Due to the lack of substantive words, it is manifested as a series of empty words, or because of the difficulty in finding words, it is expressed with too many explanations, and finally becomes nagging.
3. Visual space skill barrier
In the early stage of Alzheimer's disease, visual spatial skill disorder is likely to appear. Its symptoms are that it is impossible to accurately determine the location of objects. Some dementia patients may get lost in the familiar environment in the early stage of the disease.
4. Difficulty in writing
Because of the difficulty in writing, the content and words are not satisfactory. For example, the meaning of a letter cannot be written clearly. This is often the first symptom that draws the attention of family members, especially some old people with good cultural accomplishment. It is believed that writing errors are related to far memory impairment.
5. Loss of recognition and use
Agnosia refers to the inability of the patient to recognize an object, even though the tactile or visual elements of the object can be recognized at this time. Loss of use refers to the inability to carry out purposeful actions that have been learned, even though there are normal activities and subjective wishes.
6. Calculation obstacle
It often appears in the middle stage of Alzheimer's disease, but it may also show up in the early stage, for example, when shopping, there is often no accounting or miscalculation. There are many reasons for the occurrence of dyscalculia, which may be due to the visual space disorder (unable to correctly calculate), or the lack of understanding of arithmetic operation requirements due to aphasia, or the primary dyscalculia.
7. Poor judgment and distraction
In the early stage of Alzheimer's disease, poor judgment, loss of generalization ability, distraction and other phenomena can occur.
8. Mental disorders
Mental symptoms in the early stage can be manifested as self-centered, manic, delusional, depression, personality change, delirium, etc., and the mood is not easy to control.
9. Personality changes
Character change is very significant in some patients, most of them become very sensitive and suspicious or very afraid, or become more and more grumpy and stubborn.
10. Behavior change, movement disorder
In the early stage, the movement of Alzheimer's patients is normal. In the middle stage of the disease, the behavior of the patients is childish and clumsy, and they often work without effect or purpose.
