Alzheimer’s disease has no cure, but a new study has just found something that could reverse it

When recent studies revealed that an annual flu shot can reduce your risk Alzheimer’s disease (AD) by 40%, the news made headlines. Any advances in the prevention or management of cognitive decline deserve attention, because the disease is so devastating and incurable.

“More … than 6 million Americans of all ages have Alzheimer’s disease,” says the Alzheimer’s Association, which notes that as people age, cases of Alzheimer’s disease will continue to rise. “By 2050, the number of people aged 65 and over with Alzheimer’s disease could reach 12.7 million, barring the development of medical breakthroughs to prevent, slow or cure Alzheimer’s disease. .”

However, a recent study revealed a promising new treatment for AD that may actually reverse cognitive decline. Read on to find out what it is.

Alzheimer’s disease is just one of the diseases that cause dementia.

The National Institute on Aging (NIA) describes Alzheimer’s disease as “a brain disorder that slowly destroys memory and thinking skills and, eventually, the ability to perform the simplest tasks. Alzheimer’s disease is the most common cause of dementia in the elderly,” they write.

The NIA explains that the term “dementia” refers to “the loss cognitive functioning– thinking, remembering and reasoning – so much so that it interferes with a person’s daily life and activities.”

Different diseases can lead to dementia, but the cause of AD and other forms of cognitive decline is unknown. “Neurodegenerative disorders cause progressive and irreversible loss of neurons and brain function,” the NIA explains, adding that other diseases that can cause dementia include Lewy body dementiafrontotemporal dementia and vascular dementia.

Cognitive decline has many different causes.

With no known cure for diseases like AD, the focus is on preventative measures, which continue to be discovered as we learn more about the causes of cognitive decline.

For example, Harvard Health reported in 2019 that there is a link between gingivitis (gum disease) and Alzheimer’s disease. “A recent study indicates that the bacteria that causes gingivitis may also be linked to Alzheimer’s disease,” the site reported, explaining that this type of bacteria is called Porphyromonas gingivalis and can travel from the mouth to the brain. “Once in the brain, the bacteria release enzymes called gingipains that can destroy nerve cells, which in turn can cause memory loss and possibly Alzheimer’s.”

This research led to the recommendation that flossing and brushing your teeth, as well as practicing good oral hygiene in general, can help reduce your risk of developing Alzheimer’s disease. And there is myriad other ways to help prevent cognitive decline.

Preventive measures remain the best bet against dementia.

Eat healthy has been found to contribute to good brain health; aerobic activities such as swimming and jogging have also proven beneficialand even unexpected habits like socializing have been shown to help prevent dementia. These are all research-based recommendations to help reduce the risk of dementia, but so far the drugs developed to treat the disease are not effective as a cure.

“Current drugs can’t cure alzheimer’s disease or other dementias, but they might be able to slow it down and make life easier,” says the Weill Institute for Neurosciences Memory and Aging Center. But “drugs may not work for everyone,” the site says, noting that drugs can make the condition worse or have side effects. unwanted.

However, Medical News Today reports that a new study has revealed promising data on the treatment of dementia– and it involves a hormone you may have heard of.

This hormone has shown promising results against cognitive decline.

Oxytocin, sometimes called “the love hormone”, may hold the key to reversing cognitive decline, “Oxytocin is a hormone that is produced in the hypothalamus and released into the bloodstream through the pituitary gland“, explains Harvard Health. Although it helps to facilitate the birthing process, “Our body also produces oxytocin when we are aroused by our sexual partner, and when we fall in love“, notes the site. “That’s why it earned the nicknames ‘love hormone’ and ‘cuddle hormone’.

A study published by Neuropsychopharmacology reports revealed that researchers at Tokyo University of Science found that “a cell-penetrating derivative of oxytocin administered to the nasal passages of mice with impaired memory reversed the rodent’s cognitive impairment.”

Ajay VermaPhD, says Medical News Today that new knowledge about hormones delivered through the nasal passages “could be applied to improve cerebral delivery of many drugs”. And while the results of oxytocin in the mice used for the study are promising, “We’ll have to wait and see how that translates to humans,” Verma said.
