Alzheimer's disease progresses most rapidly in highly educated people, according to the Journal of Neurology, Neurosurgery and Psychiatry.
The study, organized by scientists from Columbia University in New York, involved 312 patients aged 65 and older with Alzheimer's disease. The disease was diagnosed in all patients about 5 years ago.
Patients underwent a series of tests to assess their neurological functions.
Tests showed that all patients had a deterioration in mental abilities, but the disease progressed most rapidly in highly educated people. Each additional year of education corresponded to an additional 0.3% deterioration in mental abilities. Memory and speed of thinking were especially noticeable in educated patients.
These changes occurred regardless of age, mental capacity at the time of diagnosis, the presence of cerebrovascular disease or depression.
According to scientists, one of the possible explanations is given by the so-called theory"
According to this theory, highly educated people have more neural connections between cells in their brains, or these neural connections work more efficiently.
Therefore, when the first lesions associated with Alzheimer's disease appear (protein deposition in the form of "senile plaques" and the formation of so-called neurofibrillary glomeruli), educated people better resist the disease. However, in the future, the disease has a greater impact on them than on less educated people, due to the greater level of damage.
Alzheimer's disease is the most common cause of dementia that develops in old and old age. The first symptoms may appear after 40 years, and after 70 years of age the incidence of the disease reaches 30%.

The higher the height, the more happiness
Experts from the Gallup research group came to an interesting conclusion. It turns out the level of education, and even happiness, depends to a certain extent on a person's height. The higher, the happier. Focusing on the average American, Gallup claims that a person who is 178 centimeters tall is about 15% happier than someone who falls short of the standard.

Marijuana will help fight senile dementia
The active ingredient in marijuana, which is banned as a narcotic drug in the US, Russia and most EU countries, can significantly slow the progression of Alzheimer's disease. According to experimenters at the Scripps Research Institute in California, the substance delta-9-tetrahydrocannabinol in marijuana prevents the degradation of the important neurotransmitter acetylcholine and does so better than currently used drugs.
