New study shows Tai Chi could lower your risk of DEMENTIA… a week after research revealed the martial art can ease Parkinson’s symptoms

The ancient Chinese martial art Tai Chi could lower the risk of dementia, according to a new study.

Scientists from Oregon Research Institute asked more than 200 people over 65 with declining memory to complete a virtual Tai Chi programme.

After five and a half months, they completed several tests to measure memory, orientation, sleep quality and depression – and results were compared to a group that did stretching exercises.

Those who did a specific type of Tai Chi – which involved saying words and phrases while holding positions designed to improve flexibility and balance – saw three times greater improvements in cognitive skills compared to the stretching group. Follow-up tests nearly a year later showed continued improvements.

Commenting on the results in the journal Annals of Internal medicine, the researchers said their findings show the exercise plan can ‘potentially lower the risk for developing dementia’. 

They added that the ‘magnitude of improvement’ seen in the study shows that Tai Chi could ‘slow or counter multiple years of cognitive decline and maintain functional capacity that is essential to living independently’. 

It comes a week after Chinese researchers found that practicing Tai Chi was linked to slower deterioration in patients with Parkinson’s Disease.

Experts from Shanghai Jiao Tong University in China followed 330 patients with the progressive neurological disease over three years, and found that those who did Tai  Chi had a slower decline, year-on-year, compared to those who didn’t.

 The team found improvements in many different types of Parkinson’s symptoms – those that affect movement like stiffness and tremor, and non-mobility problems like fatigue, speech problems and anxiety.

It’s estimated that around one in 10 Americans aged over 65 have dementia –  around 7million people. 

One noteworthy sufferer is Die Hard actor Bruce Willis, 68, who was recently diagnosed with frontotemporal dementia, as revealed by his former wife Demi Moore earlier this year. 

A common precursor for the condition is what’s known as mild cognitive impairment (MCI) – where memory, orientation and other cognitive functions are compromised, but not enough to constitute a dementia diagnosis.

Studies show that around 10-20 per cent of people over 65 with MCI go on to develop dementia within a year; it is a leading risk factor for the disease.

In the latest study, 304 older people with MCI were split into three groups: one did an hour of regular Tai Chi twice weekly for five and a half months, another did the same amount of simple stretching and the remainder did a special type of the martial art called cognitively enhanced Tai Chi.

All the groups received instructions via a video call, and completed the exercises at home.

At the end of the experiment, scores for memory, attention, language, orientiation and spacial awareness improved by three points, on average, for those in the enhanced Tai Chi group.

Those doing regular Tai Chi improved by 1.7 points, and those who stretched by just 0.3 points.

Researchers also found that the their ability to perform two tasks at once increased by 20 per cent, while there was no change in the stretching group.

Experts aren’t entirely sure what may be behind this promising benefit. However, it is thought that practicing thoughtful movements while remembering specific phrases improves connectivity between different parts of the brain. 

Other studies have found that physical activity, including Tai Chi, can increase the level of the brain hormone dopamine – which serves multiple functions including controlling movement and mood. 

One of the hallmarks of Parkinson’s Disease is a severe lack of dopamine, caused by the degeneration of nerve cells in the part of the brain called the substantia nigra, which controls movement.

IS BALLROOM DANCING GOOD FOR ELDERLY PEOPLE?

Elderly people are advised to take up tango and ballroom dancing to cut the risk of falling and injuring themselves.

In June 2017, dance scientist Dr Emma Redding, from Trinity Laban Conservatoire of Music and Dance, said dance classes could help prevent falls, which are the biggest cause of emergency hospital admissions for pensioners in Britain and kill almost 5,000 people every year.

The slower, structured dance styles of tango and ballroom provide ankle and core strength for older people, helping them keep their balance.

Older people are more at risk of falling because of muscle deterioration and a loss of balance that comes with age, as well as sight problems and the side effects of medications.

Dr Redding also said dance classes can help widowed people who are lonely, while the traditional music they waltz to can bring back valuable memories for those with dementia.

Speaking before giving a talk at Cheltenham Science Festival, she said: ‘Dancing, you take physical risks you would not on your own. You shift your weight from side to side, from front to back, as you would not do when walking.

‘This helps with ankle and core stability and makes people much more confident when moving in everyday life. 

‘The postural alignment is very important in preventing falls in older people and could help keep them safe.’ 

Dancing burns off six calories a minute in the average person, compared to 10 calories a minute for football.

This is particularly good for older people, who typically fail to achieve their guideline 150 minutes of moderate exercise and two of more days of strength exercises a week.
