Young at heart – the secret to brain health





Recent research published in the Frontiers in Aging Neuroscience journal reveals that a ‘young at heart’ mentality could be the secret to brain health.  

Jeanyung Chey from Seoul National University in Korea wanted to investigate the link between subjective and real brain age. Her team recruited 68 healthy people aged 59-84 years and performed MRI brain scans on each of them to analyse the amount of grey matter in different areas.

The participants also completed a questionnaire about how old they were and whether they felt older or younger than their actual age. Their cognitive abilities and perceived health were also assessed.

The participants who said they felt younger than their actual age were more likely to get a better score on a memory test. Also, they appeared to consider themselves more healthy, and were less likely to be depressed. 

It wasn't just performance results that were better. Participants who felt younger had increased grey matter volume in the inferior frontal gyrus and the superior temporal gyrus — areas of the brain associated with language, speech, and sound.

"We found that people who feel younger have the structural characteristics of a younger brain, said Chey. "Importantly, this difference remains robust even when other possible factors, including personality, subjective health, depressive symptoms, or cognitive functions, are accounted for."

The researchers don't know for sure whether younger brain characteristics are responsible for someone's subjective age or not, but they think those who feel older may be more aware of the ageing process of their brains.

Another possible explanation is that people who feel younger engage in more physical and mental activity, and lead a generally more stimulating life, that improves their brain health. Those who feel older may have resigned themselves to their age and stopped being so agile and spritely, which impacts their cognitive abilities.

"If somebody feels older than their age, it could be a sign for them to evaluate their lifestyle, habits and activities that could contribute to brain ageing. They should take measures to better care for their brain health," said Chey.

2016 update on Rike Park, Tbilisi: from construction to busy park

From a flat patch of uninteresting dirt, Rike Park in Tbilisi, Georgia, has transformed in four years (from 2014-2016) into a busy park full of trees, flower beds, sculptures, fountains, and events. Rike (Rikhe) Park is on the left bank of the Mt’k’vari River (the Kura River) near the Old City of Tbilisi. The Peace Bridge links the right bank to Rike Park. Rike Park is below the hillside Presidential Palace and, via cable car, it is the starting point for the ride to Sololaki Ridge (with the Narikala Fortress and the Mother of Georgia statue). The glass box-shaped cable car terminus was opened on 23 June 2012, and since then the park has continually developed into a ‘people’s park’ where people can walk around, eat at the nearby restaurants, sit next to the statue of American president Ronald Reagan, climb the steps to Avlabari district, and access the sights of Meidan Square, the Peace Bridge, the Metekhi Church, the Old City, the waterfall, the sulphur baths, and t...

The acacia thorn trees of Kenya

There are nearly 800 species of acacia trees in the world, and most don’t have thorns. The famous "whistling thorn tree" and the Umbrella Thorn tree of Kenya are species of acacia that do have thorns, or spines. Giraffes and other herbivores normally eat thorny acacia foliage, but leave the whistling thorn alone. Usually spines are no deterrent to giraffes. Their long tongues are adapted to strip the leaves from the branches despite the thorns. The thorny acacia like dry and hot conditions. The thorns typically occur in pairs and are 5-8 centimetres (2-3 inches) long. Spines can be straight or curved depending on the species.

Hop on hop off bus tourism comes to Tbilisi, Georgia

City Sightseeing buses have arrived in Tbilisi. The iconic red double-decker buses, a feature of many cities around the world since the company was established in Seville, Spain in 1999, is now in six continents and almost 100 cities. The company established its Tbilisi business in November 2013, with its operations commencing in February 2014. The 90-minute tour stops at 11 major locations in Tbilisi (with 2 to 5 minute waiting times at each location): the Old City (where it commences), Freedom Square, Rose Revolution Square, Marjanishvili Square, the Dry Bridge, Konka, Avlabari, Metekhi, Akhundov Museum, the Sulfur Baths, and European Square. Passengers can hop off at any stop and see the sights, hopping back onto the next bus at any time. Alternatively, passengers can remain on the bus for the whole tour and take photographs when the bus stops at each location. There are one day (24-hour) passes (for 35 lari – about $20) and 48-hour passes for 55 lari, with family d...
