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.

Construct validity of the NIH toolbox cognition battery in individuals with stroke

So prior to this our medical teams were completely blind in cognitive testing post stroke. Aren't you glad you were a guinea pig in your doctors unregistered research? I bet your doctor provided your results to no one.

Abstract: Study evaluated the construct validity of the National Institutes of Health (NIH) Toolbox (NIHTB) for the Assessment of Behavior and Neurological Function Cognition Battery (NIHTB-CB) in individuals with stroke. The NIHTB-CB provides a brief assessment (approximately 30 minutes) of key components of cognition. A total of 131 individuals with stroke (71 with mild stroke; 60 with moderate/severe stroke) completed the NIHTB-CB. Univariate analyses were conducted to examine the cognitive profiles of the two different stroke groups (mild versus moderate/severe stroke) on NIHTB-CB measures and composite scores. Pearson correlations were computed to evaluate relationships between NIHTB-CB and established measures to examine convergent and discriminant validity. Effect sizes and clinical impairment rates for the different NIHTB-CB measures and composite scores were also examined. Participants experiencing moderate-to-severe stroke had poorer performance than did individuals with mild stroke on several of the NIHTB cognition measures. Evidence of convergent validity was provided by moderate-to-strong correlations between the NIHTB measures and the corresponding standard neuropsychological test (Pearson correlation coefficients ranged from 0.31 to 0.88). Evidence of discriminant validity was provided by smaller correlations between different cognitive domains than correlations of measures within the same domain. Effect sizes for composite and subtest scores regarding stroke severity were generally moderate-to-large. In addition, 42 percent of the sample were exhibiting mild cognitive impairment (i.e., ≥2 low scores on fluid tests). Findings provide support for the construct validity of the NIHTB-CB in individuals with stroke.
