Elderly people who smell rose, lemon and thinner may be less likely to suffer from dementia, the study says

Elderly people who can identify odors such as roses, paint thinners, lemons, and turpentine, and who have aural, visual, and tactile sensations have half the risk of developing dementia compared to peers with significant hypoesthesia. Researchers say it could be. Although multiple obstacles were key to researchers’ research, the team found that olfactory and sharp olfactory sensations were more strongly associated with dementia than touch, hearing, and vision. Participants with a 10% reduction in olfaction were 19% more likely to have dementia, but with a 1-3% increase in risk of corresponding reductions in vision, hearing, and touch.

In a study at the University of California, San Francisco (UCSF), the authors followed about 1,794 participants in their 70s for up to 10 years to see if sensory function correlated with the development of dementia. At enrollment, all participants did not develop dementia, but 328 participants, or 18%, developed symptoms during the course of the study.

Analysis revealed that 141 out of 328 (19%) people with moderate sensory levels had dementia. According to the survey, this compares to 83 (12%) in the good range and 104 (27%) in the bad range.

This study was funded by the National Institutes of Health, the National Institute for Aging and the Alzheimer’s Society.

“Sensory deficits can result from the same disease processes that affect cognition, such as underlying neurodegeneration or stroke. Alternatively, sensory deficits, especially hearing and vision, directly affect cognition. Or it may indirectly accelerate cognitive decline through social isolation, reduced athletic performance, and worsened mental health.” Weill Institute for Neurosciences, report. “The olfactory bulb, which is important for olfaction, is affected much earlier in the course of the disease. Although olfaction is thought to be a possible preclinical indicator of dementia, hearing and vision are It may play a greater role in facilitation,” adds Brenowitz.

Alzheimer’s disease is the most common cause of dementia among the elderly. The World Health Organization (WHO) defines dementia as a syndrome (usually of a chronic or progressive nature) with a diminished ability to perform memory, thinking, behavior, and daily activities. According to the National Institute for Aging, estimates vary, but experts 5.5 million Americans, Most of whom are over 65 and may have dementia due to Alzheimer’s disease. By 2050, the number of people over the age of 65 with Alzheimer’s disease will be 13.8 millionThe Alzheimer’s Association states that it prohibits the development of medical breakthroughs to prevent, delay, or cure Alzheimer’s disease.

In the current study, participants were recruited from a random sample of Medicare-qualified adults in a study of health, aging, and body composition. Cognitive tests were conducted at the beginning of the study and repeated every two years. “Dementia was defined by tests showing a significant reduction from baseline scores, documenting the use or hospitalization of dementia drugs as a primary or secondary diagnosis,” the study said.

The team performed a “multisensory test” in the 3-5th year, measuring hearing (hearing aids were not allowed), visual contrast sensitivity test (glasses were allowed), and vibration with the thumb of the thumb. Touch test, smell. Identifies unique odors such as paint thinner, rose, lemon, onion and turpentine. The authors found that participants who remained dementia-free generally tended to have “higher cognition” at enrollment and “no paresthesia”. Moderate people tended to have multiple mild disabilities or a single moderate to severe disability. The analysis showed multiple high- to moderate-risk participants with moderate to severe disability.

“Even cognitive impairments across multiple domains were associated with an increased risk of dementia, so people with cognitive decline may be eligible for intervention before the onset of dementia.” , A high-risk group of people,” from psychiatry and behavioral sciences, epidemiology and biostatistics, the UCSF department of neurology, and the VA health care system in San Francisco.

Among other findings, the study found that 780 participants with good polysensory function were more likely to be healthier than 499 participants with poor polysensory function, and some lifestyle It has been suggested that these habits may play a role in reducing the risk of dementia. The former group were more likely to graduate from high school (85% vs 72.1%), had less diabetes (16.9% vs 27.9%), and were slightly less likely to have cardiovascular disease, hypertension, and stroke, the team said.
