1、 Definition of Alzheimer's disease
Dementia: acquired and persistent intellectual impairment syndrome due to brain dysfunction.
Alzheimer's disease: refers to a syndrome characterized by cognitive, behavioral and personality changes caused by the dysfunction of the elderly brain.
2、 Classification of Alzheimer's disease
1. Senile dementia caused by cerebrovascular disease;
Cerebral vascular dementia caused by brain degeneration;
3. There are mixed dementia of cerebrovascular dementia and senile dementia at the same time;
Dementia caused by systemic diseases such as hypothyroidism, hepatic encephalopathy and pulmonary encephalopathy.
3、 Symptoms of Alzheimer's disease
Early symptoms
Memory, working ability, emotional instability, irritability. Aggressive, loss of interest in daily activities and personality changes, but still maintain the ability to live independently.
2 Intermediate symptoms
The memory declines seriously, unable to be competent for work, and the recent events can hardly be remembered, even the major events in life; the judgment, understanding and calculation are significantly reduced, and the patients do not know friends or even relatives when they are serious; the physical activity is not flexible, and the patients can take care of themselves except for eating, dressing and defecating, and the rest of their lives need help from others Brain atrophy and slow wave increase were found in EEG.
3 late symptoms
Extremely obvious dementia state, dull and indifferent expression, bedridden, unable to carry out normal conversation, fragmented language, some walking unsteadily, staggering or limb contracture, patients' life completely unable to take care of themselves, extensive brain atrophy can be found in CT examination of the head, and comprehensive slow wave can be seen in EEG.
4、 Functional food for improving Alzheimer's disease
1 energy
The study found that people who ate more energy had a higher risk of Alzheimer's disease. Therefore, energy intake should be strictly controlled for the elderly.
2 protein
Research shows that the intake of plant protein, such as soybean protein, can reduce the incidence of Alzheimer's disease.
3 fat
There are a large number of senile plaques on the skin and brain surface of Alzheimer's disease patients, which are also the products of fat metabolism disorders, so the intake of fat should be limited for the elderly.
However, some unsaturated fatty acids, such as DHA, play a positive role in improving Alzheimer's disease, which can delay brain atrophy and improve memory loss.
4 lecithin
Lecithin can increase the ability of memory, thinking and analysis, delay brain decline and improve Alzheimer's disease.
5 carbohydrates
Carbohydrates are the basis of brain health. Brain cells are different from ordinary cells. They need higher energy sources, mainly carbohydrates.
6 vitamins
(1) vitamin C and vitamin E: prevent cerebral vascular sclerosis and senile dementia.
(2) vitamin B12 and folic acid: it is good for the production of immune protein and the improvement of Alzheimer's disease.
7 mineral elements
(1) zinc: strengthen memory, delay brain aging.
(2) aluminum: it is an important factor causing brain diseases (try to avoid excessive aluminum intake).
(3) septum: induce Alzheimer's disease.
8. Plant active ingredients
(1) alkaloids: efficient cholinesterase inhibitors
(2) saponins: good for the treatment of Alzheimer's disease
(3) phenolic ketones: beneficial to the prevention and treatment of Alzheimer's disease
(4) polysaccharides: prevention and treatment of Alzheimer's disease
