As unpleasant as it may sound, scientists claim that smelling your own farts could actually help protect your brain from Alzheimer’s disease.
According to a study carried out by researchers at Johns Hopkins Medicine, a chemical responsible for the foul smell of flatulence may play a role in slowing down cognitive decline and protecting brain cells linked to Alzheimer’s.
The key compound involved is hydrogen sulfide, the gas that gives flatulence its familiar rotten-egg odor. Researchers say this gas may help protect aging brain cells and reduce damage associated with neurodegenerative diseases.
“Our new data firmly link aging, neurodegeneration and cell signaling using hydrogen sulfide and other gaseous molecules within the cell,” said Dr. Bindu Paul, an associate professor at Johns Hopkins Medicine and co-author of the study.
Alzheimer’s affects millions of people, with symptoms ranging from memory loss to anxiety, hallucinations, and movement issues, making any potential protective discovery significant.
To investigate the effects of hydrogen sulfide, scientists used genetically modified mice designed to mimic human Alzheimer’s disease.
The mice were injected with a compound called NaGYY, which slowly releases hydrogen sulfide throughout the body. After 12 weeks, the animals were tested for changes in memory and motor function.
The results were striking.
Researchers found that mice treated with the hydrogen sulfide compound showed a 50% improvement in both cognitive ability and physical movement compared to untreated mice.
The treated mice were more active and demonstrated noticeably better memory.
“The results showed that the behavioral outcomes of Alzheimer’s disease could be reversed by introducing hydrogen sulfide,” the research team stated.
The human body naturally produces small amounts of hydrogen sulfide to help regulate various biological functions. However, levels of the gas decrease with age.
Researchers explained that when hydrogen sulfide levels drop, an enzyme called glycogen synthase beta can interact too closely with a protein known as Tau. This can lead to Tau clumping inside neurons, blocking communication between brain cells and eventually causing them to die.
“This leads to the deterioration and eventual loss of cognition, memory and motor function,” the team explained.
While the study focused on mice, researchers say the findings open the door to potential drug development aimed at slowing or preventing Alzheimer’s disease by mimicking the protective effects of hydrogen sulfide.
The Johns Hopkins team continues to study how sulfur-based compounds interact with proteins linked to Alzheimer’s in hopes of designing future treatments.
So while no one is suggesting deliberately inhaling unpleasant smells, the science behind flatulence may turn out to be more beneficial than anyone expected.
