Death patients suffer from a deterioration in the quality of life that negatively affects them and their families, and dementia includes several diseases that affect memory and thinking, which results in difficulty in practicing daily activities, and while searching for drugs that treat this problem continues, some medications that provide protection from this disease are available.
The British Telegraph website published a report talking about 5 drugs that reduce the risk of dementia, which we get to know in this report:
Fire belt vaccine (herpes herpes)
Researchers from Stanford University in the United States conducted a study published in the Nature magazine in April 2025 that made it clear that eating a fiery belt (herpes) in the middle age and beyond is not only protected from the painful rash caused by the virus, but also increases the probability of prevention of dementia as well.
The study showed that the vaccine can protect a person from 5 people from dementia within 7 years.
Dr. Pascal Gildesitzer, the epidemic scientist at Stanford University and one of the study researchers, stated that these results encouraged him to seek to search for financing to conduct extensive research to test whether the fiery belt vaccine protects the deterioration of cognitive functions.
In recent years, theories have been explained by the fact that Alzheimer’s disease may be originally due to an infection.
Dr. Gildesitzer said that the varicella zoster virus – which affects children in the waterproof of the water – may remain in the nervous system for decades and then appears in the form of a fiery belt.
With age, the body’s immunity weakens and stimulates the virus, which in turn causes devastating consequences for the brain.
Disclosure drugs
Some of those who take the famous fatty medications from the statins family see that they have troublesome side effects and cause pain in the joints and muscles.
But in a new study by researchers from universities, centers and several hospitals in South Korea and analyzed health data for more than 570,000 people, they found a remarkable side effect of the sixties in the prevention of dementia.
This study was published on April 1, 2025 in the journal “Neuroscience .. Neurosurgery and Psychiatry”, and showed that taking cholesterol -reduced medications reduces the risk of dementia by 13%.
This preventive effect also benefits people who do not suffer from a high -density lipoprotein (LDL) or what is known as harmful cholesterol.
Dr. Francisco Tamaghenini, a specialist in dementia at the University of Reding, pointed out the emergence of a theory called the “fat invading model”, which links the appearance of Alzheimer’s disease, one of the most famous forms of dementia with fat.
It was explained that the layer of cells that isolate the brain from the blood circulation becomes more permeable with age, and this may be the result of excessive drinking of wine or exposure to many strikes of accidents or sports injuries.
Increasing the permeability of this barrier between the brain and blood may lead to harmful cholesterol and its entry into the brain, which may cause damage to nerve functions, and therefore harmful cholesterol drugs such as statins contribute to reducing the risk of developing Alzheimer’s.
Celandeville (Viagra)
A study conducted by researchers from several universities and research centers in the United Kingdom – including the University of Oxford – was published in June 2024 in the magazine “Serkiochen Reservation”, the ability of the Celandeville known as the commercial name “Vaghara” to increase blood flow to large and small blood vessels in the brain.
The study indicated that Viagra reduces vascular resistance, which leads to the development of dementia resulting from weak blood flow to the brain, according to the images of ultrasound and Magnetic Resonance Imaging.
Dr. Alstir Web, a nerve consultant at the United Kingdom’s Health Services Authority, said that Viagra may treat vascular dementia caused by a vascular dysfunction, and in addition to that it expands small blood vessels, and thus relieves pressure on large blood vessels, and reduces their sclerosis from age.
Dr. Tamaghenini said that Viagra increases the production of nitric oxide gas inside the body. This gas is very important in the process of “consolidating memories”, which is the process of converting short memories into long -term memories.
Simaglotide
Simiglotide is famous for its ability to lose weight, and it may have other benefits in the face of dementia.
One of the types of drugs that simulate the glutagon-1 (GLB-1), which helps to feel full for a longer period.
Researchers from Oxford University in the United Kingdom conducted a study of people with type 2 diabetes, and found that the drugs that mimic the hormone “GLB -1” reduce the risk of developing Alzheimer’s and other dementia compared to taking cetagleptin (Janovia), a drug that reduces blood sugar level, and this study was published in the “E Clinical Medicen” magazine in 2024.
Another study conducted at the University of Imperial London College of the United Kingdom showed patients with an early stage of Alzheimer’s that taking Liraglotide one of the drugs that mimic the hormone “GLB -1” for a year is the slower rate of their brain contraction by 50% compared to those who took the placebo (Placebo), and this study was published in Alzheimer’s and Death Journal in January 2025.
According to a professor of neuroscience at the University of Imperial London College, Professor Paul Edison, drugs that mimic the hormone “GLB -1” managed to associate a number of types of brain cells, in addition to that after studying these drugs on animals it was found that they were able to remove toxic proteins and stimulate the process of repairing neurons for themselves.
Dr. Edison believes that these drugs protect neurons from damage, and they also stimulate different enzyme chains, which in turn reduce inflammation and improve memory.
Tuberculosis
The fiery belt vaccine may not be alone to protect from dementia. Researchers have studied health data for more than 130 million people to search for drugs that protect from dementia.
The researchers believe that there is a possibility of the ability of the tuberculosis to prevent the decline in cognitive abilities caused by age.
The study was conducted by researchers from several universities around the world, and published in Alzheimer’s and Death Magazine in January 2025.
Dr. Ben Andrewwood, one of the study researchers and researcher in the psychiatry of the elderly at the University of Cambridge, indicates that tuberculosis may not have a direct impact on the prevention of dementia, and despite this, its effectiveness may lie in improving the immune system in general, and thus preventing dementia.
