Tokyo, March 24 Knee pain in the elderly, which can damage the quality of life, can make them prone to depression, researchers say.

Osteoarthritis occurs when a joint becomes inflamed, usually because the protective cartilage and other tissues that cushion joints like the knee become damaged and worn over time.

Knee pain from osteoarthritis can make it harder to take care of yourself, which can damage your quality of life. In turn, it can lead to depression.

The study, led by Yuji Nishiwaki from the Toho University in Japan, showed that elderly who experienced knee pain at night while in bed, while putting on socks, or while getting in or out of a car were more likely to report having symptoms of depression.

Two years later, nearly all of them completed follow-up interviews. The participants answered questions about their knee pain and were evaluated for symptoms of depression.

Nearly 12 percent of the participants had developed symptoms of depression.

Another recently published study showed that both knee pain and functional impairments in elderly individuals are associated with the development of depressive symptoms.

“Examining elderly people’s responses to questions about pain at night and difficulties performing daily activities may be an efficient way of identifying those at high risk of developing depressive symptoms,” the researchers said. IANS

Stronger people have sharper brains: Study

Previous research by the group has already found that aerobic exercise can improve brain health

 If you thought hitting the gym only builds your physical strength, think again. A study of nearly half a million people has revealed that stronger people perform better in brain functioning tests.

Muscular strength, measured by handgrip, is an indication of how healthy our brains are, said the study published in the journal Schizophrenia Bulletin.

“Our study confirms that people who are stronger do indeed tend to have better functioning brains,” said study co-author Joseph Firth from NICM Health Research Institute, Western Sydney University, Australia.

Using data from the 475,397 participants from all around Britain, the new study showed that on average, stronger people performed better in brain functioning tests that included reaction speed, logical problem solving, and multiple different tests of memory.

The study, which used UK Biobank data, showed the relationships were consistently strong in both people aged under 55 and those aged over 55. Previous studies had only shown this applies in elderly people.

The findings also showed that maximal handgrip was strongly correlated with both visual memory and reaction time in over one thousand people with psychotic disorders such as schizophrenia.

“We can see there is a clear connection between muscular strength and brain health,” Firth, who is also an honorary research fellow at the University of Manchester in Britain, said. “But really, what we need now, are more studies to test if we can actually make our brains healthier by doing things which make our muscles stronger — such as weight training,” he added. Previous research by the group has already found that aerobic exercise can improve brain health. “These sorts of novel interventions, such as weight training, could be particularly beneficial for people with mental health conditions,” Firth said.

“Our research has shown that the connections between muscular strength and brain functioning also exist in people experiencing schizophrenia, major depression and bipolar disorder — all of which can interfere with regular brain functioning,” he added. “This raises the strong possibility that weight training exercises could actually improve both the physical and mental functioning of people with these conditions,” he said.
