Eye problems raise the risk of dementia by up to 60%
HEALTH problems with the eye significantly raise the risk of dementia, a study shows.
Patients with deteriorating vision are more likely to end up with an impaired ability to remember, think or make decisions, researchers said. They analysed data on 12,364 adults aged 55 to 73 and found the risk of dementia was 26 per cent higher in those with agerelated macular degeneration.
The equivalent figure was 11 per cent for cataract sufferers and 61 per cent for those with diabetes-related eye disease.
The researchers, from the Guangdong Academy of Medical Sciences in China, said they could not establish reasons for the links. However it could be that eye conditions are associated with well-known risk factors for dementia such as heart disease.
Prolonged stress raises the risk of high blood pressure and heart issues by up to 90 per cent, scientists say. Dr Kosuke Inoue, of Kyoto University in Japan, said his findings suggested that testing for stress hormones could be helpful to head off illness.
WE’VE just seen a red letter day in the annals of healthcare — it will also give anti-vaxxers something to think about.
A recent study has confirmed that a single dose of a newly created antibody called CIS43LS is highly effective against malaria, which in Africa alone causes 400,000 deaths a year, the majority in children.
Many are aware of the tablets you must take when travelling to regions where malaria is present — the problem is that while such drugs are helpful, they aren’t always effective.
In the latest study, the antibody was given by injection to 25 volunteers. The ‘vaccinated’ volunteers and a control group were then exposed to mosquitoes known to be infected with the malaria-causing parasite.
While all the volunteers were bitten, none of the injected group developed malaria, while most of the control group did — and were rescued by medication.
This is an outstanding triumph. Of course, we need to see data from larger studies before the new prevention is able to enter common use. But the application of this careful and diligent science, destined to save millions of lives, is one to challenge anti-vaxxer obduracy.
