Abnormal senile plaque induces Alzheimer’s disease

When people reach old age, they often grow brown spots on their skin. They vary in size and size. The spots are clearly defined and there is no itching.

This is the age spots or age spots, medically known as senile pigment spots.

銆€銆€First of all, the age spots on the skin have little effect on people.

However, sometimes similar senile plaques will grow into the human body, such as the liver, heart, nerve cells and brain tissue, and increase with age, causing people’s attention.

銆€銆€Studies have confirmed that senile pigmented plaques are most likely to accumulate in brain cells, while the hippocampus, which extends deep in the lower part of the brain, is particularly dense.

The hippocampus has two functions: one is due to memory, that is, it only records events that have been done or happened recently, but it is not preserved for a long time; the second is the memory of the sequence between the two events and their connections.This can be expected, speculation and other thinking activities.

銆€銆€Old people tend to be close to forgetfulness, and the distant things are clear, or the words are reversed three times and four times. The foreword is not followed. The first one is that the senile pigmentation spots cause damage to the hippocampus.

Hippocampal functional impairment is a gradual process, and dementia symptoms occur only when the lipofuscin pigment accumulates to a certain extent.
