How current screening methods miss mild cognitive impairment

Brains

Researchers at the University of California San Diego School of Medicine and Veterans Affairs San Diego Healthcare System have found that the screening tools currently used to identify mild cognitive impairment (MCI) often give a false-negative. This means that people who are likely to go on to develop Alzheimer’s may not be getting the timely care that they need. MCI ...

How laxatives can tell us more about Parkinson’s

Alzheimer's

Researchers from King’s College London have just undertaken a retrospective study to review laxative use among 79 patients with Parkinson’s disease. Each of the patients had been part of a gut-brain clinic that ran between August 2002 and July 2014. The results of the analysis showed that a combination of gut factors are linked to the disease mechanisms of Parkinson’s. ...

Why it’s impossible to tickle yourself

Eye

Most of us love to be tickled, although some of us may be more ticklish than others. However, one thing is for sure, we can’t tickle ourselves. But why is that so? Well, it’s all down to how we see, and how we perceive movement. Try this for starters. Close one of your eyes, then carefully push against the side ...

Scientists find new ways to grow blood vessels in the lab

blood-vessels

Scientists from the University of Bath’s Department of Pharmacy and Pharmacology have found a new way to produce 3D-networks of blood vessels. This means that it could be easier to grow tissues and organs for transplantation into patients, in the lab. These blood vessel networks are vital to ensure the survival of the tissues and yet so far being able ...

Why you still feel pain long after an injury has gone

sprained ankle

Scientists from King’s College London have revealed why chronic pain can persist long after the injury that caused it has healed. While the research is still in its infancy, it goes a long way to explain how seemingly innocuous injuries can leave ‘footprints’ at a molecular level, which ultimately lead to more lasting damage and long-term pain. Chronic pain is ...

New research suggests dementia may be caused by auto-inflammation

Dementia

New research published this month by the University of Adelaide has suggested that auto-inflammation may be a cause of dementia. This suggestion means that scientists may have to change their current thinking. This new theory developed by the Adelaide researchers puts forward the idea that an out-of-control immune system could be a cause for both dementia and other neurodegenerative diseases. ...

REM sleep important for creating memories – in mice

sleep

While some scientists have always suspected that we form our memories during REM (rapid eye movement) sleep, until now there hasn’t been any direct proof. However a team of researchers from McGill University have recently carried out a study which has shown that REM sleep, the part of sleep when we’re most likely to dream, is important for creating memories ...

New trial of robotic legs help patients to walk again

Robotic legs could allow paralysed people to walk again

In recent months there have been many reports of research teams and engineers developing pioneering techniques to enable people who have lost the use of their legs to walk again. Now a team from the School of Engineering and Digital Arts at the University of Kent are about to carry out the first clinical trials of a new set of ...

Risk of developing vascular dementia increased by high blood pressure

blood Pressure

While we’re already aware that having high blood pressure can cause all sorts of complications and medical conditions from heart attack to stroke, a new study carried out by The George Institute or Global Health suggests that having higher than normal blood pressure can also increase the risk of developing vascular dementia. Vascular dementia is on the increase around the world Vascular ...
