Deans' stroke musings

Changing stroke rehab and research worldwide now.Time is Brain!Just think of all the trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 493 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It's quite disgusting that this information is not available from every stroke association and doctors group.

Blueberry concentrate improves brain function in older people

I wonder how many real blueberries this would be?I do 1-2 pints a week in my cereal.

Drinking concentrated blueberry juice improves brain function in older people, according to research by the University of Exeter.

In the study, healthy people aged 65–77 who drank concentrated blueberry juice every day showed improvements in cognitive function, blood flow to the brain and activation of the brain while carrying out cognitive tests. There was also evidence suggesting improvement in working memory.

Blueberries are rich in flavonoids, which possess antioxidant and anti–inflammatory properties.

Dr Joanna Bowtell, head of Sport and Health Sciences at the University of Exeter, said: “Our cognitive function tends to decline as we get older, but previous research has shown that cognitive function is better preserved in healthy older adults with a diet rich in plant–based foods.

“In this study we have shown that with just 12 weeks of consuming 30ml of concentrated blueberry juice every day, brain blood flow, brain activation and some aspects of working memory were improved in this group of healthy older adults.”

Of the 26 healthy adults in the study, 12 were given concentrated blueberry juice – providing the equivalent of 230g of blueberries – once a day, while 14 received a placebo.

Before and after the 12–week period, participants took a range of cognitive tests while an MRI scanner monitored their brain function and resting brain blood flow was measured. Compared to the placebo group, those who took the blueberry supplement showed significant increases in brain activity in brain areas related to the tests.

The study excluded anyone who said they consumed more than five portions of fruit and vegetables per day, and all participants were told to stick to their normal diet throughout.

Previous research has shown that risk of dementia is reduced by higher fruit and vegetable intake, and cognitive function is better preserved in healthy older adults with a diet rich in plant–based foods. Flavonoids, which are abundant in plants, are likely to be an important component in causing these effects.

The new paper, “Enhanced task–related brain activation and resting perfusion in healthy older adults after chronic blueberry supplementation”, was published in the journal Applied Physiology, Nutrition and Metabolism.

The research was carried out in association with the University of the West of England, and the concentrated blueberry juice (BlueberryActive) and some funding for the study was provided by CherryActive Ltd, which produces cherry, beetroot and blueberry products in concentrate and capsule form.
