Leslie Iversen obituary
Neuropharmacologist who searched for new gateways for drugs to treat the brain and mindAfflictions of the mind and brain, from stroke to schizophrenia, remain among the most challenging to treat, even after more than half a century of discoveries about the brain ’s biochemistry and how it responds to drugs. The neuropharmacologist Leslie Iversen, who has died aged 82, devoted his career to making sense of the interplay of signalling molecules in the nervous system that might provide sites where drugs could act.After directing laboratories in both the public sector and the pharmaceutical industry, in his later years Ivers...

Do we have to age?
The biologist Andrew Steele thinks ageing is a disease that can be treated. But if we had a cure for getting old, what would that mean for us?When the biologist Andrew Steele tells people his thoughts on ageing – that we might one day cure it as if it were any other disease – they are often incredulous and sometimes hostile. Once, at a friend’s wedding, he left a group of guests mildly incensed for suggesting that near-future humans might live well into their 100s. A similar thing happens at dinner p arties, where the responses are more polite but no less sceptical. He understands the reaction. We think of ageing as ...

Statins do not cause muscle aches and pains, study finds
UK researchers seek to dispel concerns over pills prescribed for those at higher risk of heart attack and strokesStatins are generally not the cause of the muscle aches and pains that stop some people taking the pills prescribed to protect them against serious heart problems, according to a novel study that hopes to dispel some of the concerns.Two million people in the UK who are at higher risk of heart attack and strokes are eligible for statins, but many people refuse them or have stopped taking them because of sometimes alarming and widespread reports of muscle pain. But the study funded by the National Institute of Hea...

Taboo stops south Asian people in UK seeking help for dementia, says charity
Exclusive: Alzheimer ’s Society says fear of embarrassment or misunderstanding stops thousands coming forwardThousands of south Asian people living with dementia in the UK are being denied access to help and support because stigma and taboo deter them from getting diagnosed, a charity has warned.People from south Asian communities are more likely to develop dementia than the general UK population due to being at higher risk of other illnesses, such as heart disease, stroke and diabetes, that increase the risk of dementia.Continue reading...

Balancing on one leg may be useful health test in later life, research suggests
People who cannot stand on one leg for 10 seconds are found to be almost twice as likely to die within 10 yearsIf you have difficulty standing on one leg, it could be a sign of something more serious than overdoing it at the office summer drinks party. Middle-aged and elderly people who cannot balance on one leg for 10 seconds are almost twice as likely to die within 10 years than those who can, research suggests.How well a person can balance can offer an insight into their health. Previous research, for instance, indicates that an inability tobalance on one leg is linked to a greater risk of stroke. People with poor balan...

Blobs of human brain planted in rats offer new treatment hope
Scientists suggest patient ’s own cells could be grown in the lab and used to repair stroke or trauma injuriesBlobs of human brain tissue have been transplanted into the brains of rats in work that could pave the way for new treatments for devastating brain injuries.The groundbreaking study showed that the “human brain organoids” – sesame seed-sized balls of neurons – were able to integrate into the rat brain, linking up with their blood supplies and communicating with the rat neurons.Continue reading...

A measurement for chronic pain is a scientific holy grail – and we’re getting closer | Abdul-Ghaaliq Lalkhen
People who have chronic pain without a visible injury are often not believed, but new research can help visualise that painMost people, including doctors, do not appreciate that the organ that produces pain is the brain. A broken bone, damaged tissue or a bleeding wound is often the focus, but the experience of pain is the sum total of more than just the physical injury – it is the result of information sent from our nerves being filtered through an individual’s unique psychological makeup, genetics, gender, beliefs, expectations, motivations and emotional context. Pain is therefore an individual experience, and often ...
