A smile is not just a smile, it can boost your memory!

Smile_memoryMay 6: A new study has revealed that humor and laughter can help lessen the damage that stress hormone cortisol has on memory and learning ability in the elderly. According to the researchers at Loma Linda University, there was a significant decrease in cortisol concentrations among both groups who watched a funny video and showed greater improvement in all areas of the memory assessment when compared to controls.

Gurinder Singh Bains said that their findings offer potential clinical and rehabilitative benefits that can be applied to wellness programs for the elderlyand the cognitive components, such as learning ability and delayed recall, become more challenging as people age and are essential to older adults for an improved quality of life.

The researchers said that the less stress one has the better their memory, as humor reduces detrimental stress hormones like cortisol that decrease memory hippocampal neurons, lowers the blood pressure, and increases blood flow and mood state.

The study revealed that the act of laughter-or simply enjoying some humor-increases the release of endorphins and dopamine in the brain, which provides a sense of pleasure and reward and the positive and beneficial neurochemical changes, in turn, make the immune system function better.

What are reasons for forgetfulness?

Forgetfulness, also called mild cognitive impairment, need not cause you much concern if it happens once in a while, but if you are forgettings quite often like Vicky, then it’s time to delve deeper into the cause of your forgetfulness.

Age, medical conditions, and emotional problems – all of these can contribute to forgetfulness. Most memory problems can be treated, so see your doctor if you or your loved one tend to forget stuff often. Here’s a 101 on the causes of forgetfulness.

1. Ageing

If you are in your 50s or 60s or maybe 70s, you may suddenly feel you are losing it. You stand in front of your refrigerator and you just don’t seem to recollect what it was that you wanted to take out of it. Or, you are discussing books with your friend and you are trying very hard to remember the title of the book you were reading the day before. These are the memory changes during normal ageing and you do not have to be alarmed, but they may also be the beginning symptoms of Alzheimer’s.

We start forgetting stuff because as we age the nerve impulses that travel between cells and cell membrane in the brain slows down. This decline in cognitive ability is not abrupt and progresses imperceptibly over decades, say scientists from the Johns Hopkins School of Medicine. It is natural and there is not much you can do to stop the progression of memory lapses other than try and socialize more and do things that help keep your memory sharp and you alert.

Researchers have found the rates of lung cancer are higher in young women than men.

The study, published in the journal Pediatrics, examined lung cancer rates in young adults in 40 countries across five continents and uncovered a trend of higher lung cancer rates in women compared with men in recent years.

The emerging trend was widespread, affecting countries across varied geographic locations and income levels.

The changes appeared to be driven by a rising rate of adenocarcinoma lung cancer among women, said the study researchers from University of Calgary in Canada.

Lung cancer rates have been higher among men than women because men started smoking in large numbers earlier and smoked at higher rates; however, recent studies have reported converging lung cancer incidence rates between sexes.

Among men, age specific lung cancer incidence rates generally decreased in all countries, while in women the rates varied across countries with the trends in most countries stable or declining, albeit at a slower pace compared to those in men.

For the findings, lung and bronchial cancer cases between 30-64 age group from 1993-2012 were extracted from cancer incidence in five continents.

The study found the higher emerging rates of lung cancer in young women compared to young men.

According to the researchers, future studies are needed to identify reasons for the elevated incidence of lung cancer among young women.

New York, Jul 30: Can the coronavirus spread through the air? Yes, it's possible.

The World Health Organisation recently acknowledged the possibility that Covid-19 might be spread in the air under certain conditions.

Recent Covid-19 outbreaks in crowded indoor settings — restaurants, nightclubs and choir practices — suggest the virus can hang around in the air long enough to potentially infect others if social distancing measures are not strictly enforced.

Experts say the lack of ventilation in these situations is thought to have contributed to spread, and might have allowed the virus to linger in the air longer than normal.

In a report published in May, researchers found that talking produced respiratory droplets that could remain in the air in a closed environment for about eight to 14 minutes.

The WHO says those most at risk from airborne spread are doctors and nurses who perform specialized procedures such as inserting a breathing tube or putting patients on a ventilator.

Medical authorities recommend the use of protective masks and other equipment when doing such procedures.

Scientists maintain it's far less risky to be outside than indoors because virus droplets disperse in the fresh air, reducing the chances of Covid-19 transmission.

Feb 22: The subjective feeling of well-being experienced by many people with the practice of meditation is associated with specific changes in the brain, according to a study which may lead to better clinical recommendations of the practice.

The study, published in the journal Brain and Cognition, examined the effects of the technique known as Transcendental Meditation (TM), which consists of the silent repetition of a meaningless sound.

In the study, the researchers from the IMT School for Advanced Studies Lucca in Italy, enrolled 34 healthy young volunteers and divided them in two groups.

They said the first group practised TM 40 minutes per day in two sessions of 20 minutes each, one in the morning and the other in the evening.

The second group, the scientists said, did not change its daily routine.

Using questionnaires, they also measured the anxiety and stress levels of all the participants at the beginning of the study, as well as the subjects' ability to manage stressful situations.

According to the researchers, the participants were also subjected to a functional magnetic resonance imaging (fMRI) brain scan, in order to measure the organ's activity at rest, and changes in the excitation among different cerebral areas.

They repeated the tests after three months, at the end of the study.

According to the study, the levels of anxiety and stress perceived by the subjects who followed the meditation program were significantly reduced in comparison with those of the volunteers who did not practice TM.

"Magnetic resonance imaging also shows that the reduction of anxiety levels is associated with specific changes in the connectivity between different cerebral areas, such as precuneus, left parietal lobe and insula, which all have an important role in the modulation of emotions and inner states," said study co-author Giulia Avvenuti from the IMT School for Advanced Studies Lucca.

"In the control group, instead, none of these changes was observed. The fact that Transcendental Meditation has measurable effects on the 'dialogue' between brain structures involved in the modulation of affective states opens new perspectives for the understanding of brain-mind relationships," said Pietro Pietrini, IMT School's Director, and co-author of the study.

"It also extends the results of recent research suggesting that drugs therapies and psychotherapy leverage on the same biological mechanism," Pietrini said.

According to the researchers, even a few months of practice of TM can have positive effects which can be correlated with measurable changes in the brain.
