If You Don’t Use It, You Lose It


It was once believed that we are born with a certain number of brain cells, and that these slowly died off as we age. We know now that not only does the brain continually produce new neurons but that the connectivity between them becomes richer and more productive as we age, particularly if we stimulate the process through learning. And what we learn is important. Tasks which have no ‘end point’, where we can only get better with time and practise, can cause significant brain changes related to hearing, memory and mobility.

When it comes to communication, it has been shown that we can continuously grow our vocabulary and our capacity to make innovative associations between and among concepts. Similarly, reasoning and problem-solving skills tend to get sharper. There is no ‘end point’ in this kind of learning.

‘Open ended’ learning activities can include juggling, learning a language, playing an instrument, and even developing expertise in challenging games such as chess or bridge. Along with the ‘usual suspects’ (not smoking, keeping blood pressure, cholesterol and blood-sugar levels within recommended limits, eating a healthy diet, exercising and limiting alcohol consumption) we know now that open-ended learning is a potent preventative strategy against the onset and effects of dementia.

There is a good chance that you remember your wedding day. You can recall your favourite teacher at school. Holiday memories are often very strong because of the family connections involved. People around the world are ageing rapidly, and there are more than 900 million people over the age […]

The Power of Volunteering

Caring For Ageing Parents

They’ve cared for us all our lives, but what happens as our parents enter the challenging stage of old age and need support? The oft-circuitous journey of caring for ageing parents catches many of us off guard. We are torn between our desire to help and a deep sense of filial duty along with their need to maintain autonomy. The Australian population distribution has been changing with an increase of older people aged 65 and over. In the 2016 Australian Bureau of Statistics census report it is found that nearly one in every six people (16 per cent) was aged 65 years and over, an increase of 664,500 since 2011. Additionally, in 2016 there were almost half a million people […]
