"Dr Richard Greenwood says at launch of study into traumatic head injuries ........
"The study, published in the Journal of the American Medical Association Psychiatry, tested 220,000 people .......... "
It doesn't necessarily mean that this is a new study
and the quote doesn't include any dates, calls for papers, abstracts ....
I don't see any up to date news unless I read the BBC web-site, because we don't buy daily papers
Went off to do a google and found that the study 'was published on Wed.' in journal JAMA Psychiatry but it doesn't state which Wednesday
and I sourced this via the Times in India
Also, unless Richard has examined Michael or spoken closely to his Consultants and seen recent scans, he is only able to generalise and give opinions based on his experience ........only time will tell if there is anywhere near a 'good' improvement. James Cracknell is the other recent brain injury sports person and he is open about his problems now and those he has been told to expect.
