So rather than prevent a lot of disability by stopping the
neuronal cascade of death they went down the route of trying to ameliorate the problems. Damn it all, learn about cause and effect.

Abstract
BACKGROUND:
Cognitive
impairments occur frequently after stroke and contribute to significant
disability. Strategy training shows promise but has not been examined
in the acute phase of recovery.
OBJECTIVE:
We
conducted a single-blind randomized pilot study estimating the effect
of strategy training, relative to reflective listening (attention
control), for reducing disability and executive cognitive impairments.
METHODS:
Thirty
participants with acute stroke who were enrolled in inpatient
rehabilitation and had cognitive impairments were randomized to receive
strategy training (n = 15, 10 sessions as adjunct to usual inpatient
rehabilitation) or reflective listening (n = 15, same dose). The
Functional Independence Measure assessed disability at baseline,
rehabilitation discharge, 3, and 6 months. The Color Word Interference
Test of the Delis-Kaplan Executive Function System assessed selected
executive cognitive impairments (inhibition, flexibility) at baseline,
3, and 6 months.
RESULTS:
Changes
in Functional Independence Measure scores for the 2 groups over 6
months showed significant effects of group (F1,27 = 9.25, P = .005),
time (F3,74 = 96.00, P < .001), and group * time interactions (F3,74 =
4.37, P < .007) after controlling for baseline differences in stroke
severity (F1,27 = 6.74, P = .015). Color Word Interference Inhibition
scores showed significant effects of group (F1,26 = 6.50, P = .017) and
time (F2,34 = 4.74, P = .015), but the group * time interaction was not
significant (F2,34 = 2.55, P = .093). Color Word Interference Cognitive
Flexibility scores showed significant effects of group (F1,26 = 23.41, P
< .001), time (F2,34 = 12.77, P < .001), and group * time
interactions (F2,34 = 7.83, P < .002). Interaction effects suggested
greater improvements were associated with strategy training.
CONCLUSIONS:
Strategy
training shows promise for addressing disability in the first 6 months
after stroke. Lessons from this pilot study may inform future clinical
trials.
