Having someone to talk to could help stave off Alzheimer’s in middle-aged people, study claims
Having a ‘good listener’ among your friends and family can help prevent Alzheimer’s and slow down the rate at which the brain ages by up to four years, according to researchers.
They found older adults with a healthy social support network had brains that were, in functioning terms, four years younger than those who did not have the same kind of people around them.
It is not just a case of being there for the elderly to talk to, the effects can start to work on adults younger than 55 too, said the study by New York University’s Grossman School of Medicine.

They analysed brain cognitive function – one of the signs of degenerative ageing diseases such as Alzheimer’s – on 2,171 volunteers with an average age of 63 for the specialist online journal JAMA Network Open.
The results were clearly better for those who, said the report, ‘simply had someone available most of all of the time whom you can count on to listen to you when you need to talk.’
Lead researcher, Joel Salinas, said: ‘This study adds to growing evidence that people can take steps, either for themselves or the people they care about most, to increase the odds they’ll slow down cognitive aging or prevent the development of symptoms of Alzheimer’s disease — something that is all the more important given that we still don’t have a cure for the disease.’
Without the ‘good listener’, brain function can start to decline in adults during their 40s and 50s to the point where their brains are four years ‘older’ than those with a good listener to hand.
Salinas added: ‘These four years can be incredibly precious. Too often we think about how to protect our brain health when we’re much older, after we’ve already lost a lot of time decades before to build and sustain brain-healthy habits.
‘But today, right now, you can ask yourself if you truly have someone available to listen to you in a supportive way, and ask your loved ones the same.
‘Taking that simple action sets the process in motion for you to ultimately have better odds of long-term brain health and the best quality of life you can have.’
The research recommends that doctors should look at the social history of patients to see if they people around them they can talk to.
As well as ageing the brain, the lack of such support can also lead to isolation and depression.
Salinas said: ‘Loneliness is one of the many symptoms of depression, and has other health implications for patients.
‘These kinds of questions about a person’s social relationships and feelings of loneliness can tell you a lot about a patient’s broader social circumstances, their future health, and how they’re really doing outside of the clinic.’
To look at brain function, the volunteers – part of a long term health study in the US – were assessed on the kind of contact they had with others and whether it included such factors as listening but also good advice, love and affection and emotional support.
The researchers then used MRI scans as well to measure cerebral brain volume – lower volumes mean lower cognitivie function.
The study added: ‘While there is still a lot that we don’t understand about the specific biological pathways between psychosocial factors like listener availability and brain health, this study gives clues about concrete, biological reasons why we should all seek good listeners and become better listeners ourselves.’
