Deans' stroke musings: The Cattell-Horn-Carroll model of cognitive abilities

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 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:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. 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 lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

The Cattell-Horn-Carroll model of cognitive abilities

If this is the best out there in the world, is your doctor/stroke department using it to determine your cognitive problems post-stroke? Or are they using cheap, just good enough testing? Or any testing at all? I was tested and even though I passed the hardest section of a memory test asking you to sort letters and numbers low to high the doctor refused to consider me normal.

The Cattell-Horn-Carroll model of cognitive abilities

The Cattell-Horn-Carrol (CHC) theory of cognitive abilities represents the most accurate and psychometrically validated understanding of the structure of human cognitive abilities currently available (Alfonso, Flanagan, & Radwan, 2005; James, Jacobs, & Roodenburg, 2015). The theory is grounded in more than fifty years of factor analytic research, and developmental studies of cognitive abilities, genetic heritability research, and neurocognitive analyses have all contributed to its validity base (Evans, Floyd, McGrew, & Leforgee, 2002).
CHC theory consists of two components; a taxonomy of cognitive abilities, and a set of theoretical explanations as to how and why people differ in terms of their various cognitive abilities, which is embedded within the taxonomy (Schneider & McGrew, 2012). It combines the Cattell-Horn Fluid-Crystallised (Gf-Gc) and Carroll three-stratum models to provide a broad taxonomic umbrella for testing hypotheses regarding various aspects of human cognitive abilities and understanding the structure of human intelligence (McGrew, 2009; Newton & McGrew, 2010). The current model of CHC theory includes 16 broad cognitive abilities, which are subsumed by over 80 narrow abilities, with the broad abilities described as follows (Flanagan & Dixon, 2013; McGrew 2009; Newton & McGrew, 2010; Schneider & McGrew, 2012):
