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.
My back ground story is here:

The Reason Many Face Sizable Extra Dementia Risk

Since you already have a sizable risk of dementia you'll have to ask your doctor the EXACT  definition of heavy traffic and measure it from your house so you can move away from it.
1. A documented 33% dementia chance post-stroke from an Australian study?   May 2012.
2. Then this study came out and seems to have a range from 17-66%. December 2013.
3. A 20% chance in this research.   July 2013.
The first study to identify a 10% increased dementia risk resulting from home location.
One-in-ten cases of dementia could be down to living near busy roads, new research finds.
Scientists had previously guessed that both traffic noise and air pollution may contribute to neurodegenerative disorders.
But this is the first study to find evidence of the link.
The results from a study of 6.6 million people in Canada.
It found that living within 50 metres of a busy road significantly raised the risk of dementia.
The study looked at the link between living near a busy road and developing:
  • multiple sclerosis,
  • Parkinson’s disease,
  • and dementia.
Only dementia risk was associated with living near a busy road.
The further people lived from a busy road, the more their risk reduced:
  • 7-11% higher risk for those living within 50 metres.
  • 4% higher risk for those living 50-100 metres away.
  • 2% higher risk for those living 101-200 metres.
  • No additional risk for those living more than 200 metres away.
Dr Hong Chen, the study’s first author, said:
“Despite the growing impact of these diseases, little is known about their causes and prevention.
Our study suggests that busy roads could be a source of environmental stressors that could give rise to the onset of dementia.
Increasing population growth and urbanisation has placed many people close to heavy traffic, and with widespread exposure to traffic and growing rates of dementia, even a modest effect from near-road exposure could pose a large public health burden.
More research to understand this link is needed, particularly into the effects of different aspects of traffic, such as air pollutants and noise.”
The study also found that exposure to both nitrogen oxide and fine particulate matter were both linked to dementia risk.
Although both are common pollutants, they did not explain the full risk, which may be attributable to other factors, such as noise pollution.
Dr Lilian Calderón-Garcidueñas, writing in a linked article, said:
“The significant association of newly diagnosed cases of dementia in the study period between 2001 and 2012 with the proximity to traffic road less than 50 m-300 m versus more than 300 m, and the robust observation of dementia involving predominantly urban versus rural residents, opens up a crucial global health concern for millions of people…
The health repercussions of living close to heavy traffic vary considerably among exposed populations, given that traffic includes exposures to complex mixtures of environmental insults…
We must implement preventive measures now, rather than take reactive actions decades from now.”
The study was published in the journal The Lancet (Chen et al., 2016).
