Loss of smell may point to dementia risk among elderly

ELDERLY

New York, Sep 30: Facing smell loss may be an important early sign marking older adults at higher risk of cognitive decline which leads to dementia, a finding that may help develop new treatments and preventative interventions for the neurodegenerative disease, researchers say.

“Loss of the sense of smell is a strong signal that something has gone wrong and significant damage has been done,” said lead author Jayant M. Pinto, Professor at the University of Chicago.

For the study, published in the Journal of the American Geriatrics Society, the team conducted a long-term study of nearly 3,000 adults, aged 57 to 85.

The results showed that participants who could not identify at least four out of five common odours were more than twice as likely as those with a normal sense of smell to develop dementia within five years.

Nearly 80 percent of those who provided only one or two correct answers also had dementia, with a dose-dependent relationship between degree of smell loss and incidence of dementia.

“These results show that the sense of smell is closely connected with brain function and health,” Pinto said.

The olfactory system or sense of smell also have stem cells which self-regenerate. Thus, “a decrease in the ability to smell may signal a decrease in the brain’s ability to rebuild key components that are declining with age, leading to the pathological changes of many different dementias”, noted co-author Martha K. McClintock, Professor at the varsity.

Losing the ability to smell can have a substantial impact on lifestyle and well-being, as smells influence nutrition and mental health.

“Being unable to smell is closely associated with depression as people don’t get as much pleasure in life,” Pinto said.

Cycling, walking in nature may improve your mental health

walk-walking

London, Oct 20: People who commute — walking or cycling — through natural environments are more likely to develop better mental health than those who commute less, according to a new study.

Natural environments included all public and private outdoor spaces that contain ‘green’ and/or ‘blue’ natural elements such as street trees, forests, city parks and natural parks/reserves and all types of water bodies.

“Mental health and physical inactivity are two of the main public health problems associated with the life in urban environments. Urban design could be a powerful tool to confront these challenges and create healthier cities. One way of doing so would be investing in natural commuting routes for cycling and walking,” said Mark Nieuwenhuijsen from the University of Barcelona.

For the study, published in the journal, Environment International, the research team examined nearly 3,600 participants who answered a questionnaire about their commuting habits and their mental health.

The findings showed that respondents commuting through natural environments on a daily basis had on average a 2.74 point higher mental health score compared to those who commuted through natural environments less frequently.

This association was even stronger among people who reported active commuting, the team said.

“From previous experimental studies we knew that physical activity in natural environments can reduce stress, improve mood and mental restoration when compared to the equivalent activity in urban environments,” said first author Wilma Zijlema from the varsity.

“Although this study is the first of its kind to our knowledge and, therefore, more research will be needed, our data show that commuting through these natural spaces alone may also have a positive effect on mental health.”
