A new study from Ohio State University, US, suggests that sociability, especially later in life, may bring many mental and physical health benefits — it can protect against cognitive decline.
For their research, the scientists included mice aged 15–18 months. As a part of an experiment, they were divided into two groups. One group was housed in pairs modeling “an old couple”. The other mice were placed into groups containing 6 rodents. They were given the conditions modeling housing condition for 3 months.
Having analyzed the received results, the scientists concluded that mice that were living in a group were better in remembering new locations and new things.
The researchers insist that it is important for people to make decisions about choosing a place to live when they get older, as these choices could either facilitate social activities or prevent individuals from maintaining a rich social life.
A new research from the University of Edinburgh, UK, suggests that cheap cilostazol tablets may reduce damage to arteries, which lead to blood clots, resulting in strokes and cognitive decline.
The researchers plan to assess the medications’ ability to cut the risk of lacunar strokes and dementia within the next three years.
Dr. Doug Brown from the Alzheimer’s Society says: “With no new dementia drug in 15 years – but one person every three minutes developing it – the race is on to find desperately needed drugs that can prevent people getting dementia. Finding an existing drug which can prevent dementia would be a huge breakthrough.”
A recent research suggests that people with high blood sugar experience worse long-term cognitive decline compared to their peers with the normal level of blood sugar.
For their study, a team of researchers tracked 5,189 participants, including 55% women, whose average age was 66 years. They analyzed their level of cognitive function between 2004–2005 and 2014–2015. Over time, the scientists monitored levels of HbA1c, or glycated hemoglobin, a measure of blood sugar control.
The analysis of the received data showed that participants with greater levels of HbA1c experienced much higher rate of decline.
The researchers, led by epidemiologist Wuxiang Xie from Imperial College London, explain in their paper: “Our findings suggest that interventions that delay diabetes onset, as well as management strategies for blood sugar control, might help alleviate the progression of subsequent decline over the long-term.”
Recently, the researchers discovered that drinking tea on a regular basis can more than halve the risk of cognitive decline in senior adults, especially in those with a genetic risk of the Alzheimer’s disease. The research was published in The American Journal of Public Health.
For their study, lead investigator Feng Lei from the Department of Psychological Medicine at National University of Singapore’s (NUS Yong Loo Lin School of Medicine and colleagues analyzed data from 957 Chinese adults aged 55 and older. The scientists collected information about tea consumption of the participant between 2003 and 2005. They recorded how much tea the participants drank, how often and what type of tea they drank.
Having analyzed the collected data, the researchers concluded that those who consumed tea on a daily basis had 50% lower risk of cognitive decline, compared to those who drank tea seldom.
According to a new study, a rambling and non-specific speech might be the early sign of the coming mental decline – Alzheimer’s disease or dementia. Researchers managed to find evidence that people with mild cognitive impairment are more likely to use more words than necessary and they usually need more time to find the right words compared to their healthy counterparts.
For the study, the researchers compared the language abilities of 22 healthy young persons, 24 senior persons, and 22 people with MCI. Patients with MCI gave long and redundant with their answers to simple questions.
Lead researcher Janet Cohen Sherman from Massachusetts General Hospital explains: “They were much less concise in conveying information, the sentences they produced were much longer, they had a hard time staying on point and I guess you could say they were much more roundabout in getting their point across.”
