Well shit, enriched environment has been out there since 2011. Is your stroke hosital using this intervention? Or is incompetence reigning supreme?

Ischemic stroke is the second leading cause of death worldwide.
Ischemia-induced cognitive dysfunction may result in a poor quality of
life. Synaptic plasticity plays a key role in cognition promotion. An
enriched environment (EE), which can attenuate cognitive deficits in
chronic cerebral hypoperfusion, has been shown to facilitate synaptic
plasticity. However, the effect of EE on synaptic plasticity in
bilateral cerebral hemispheres in stroke remains unclear. This study
used a permanent middle cerebral artery occlusion mouse model, which was
divided into standard housing and EE groups. The Morris water maze test
was performed to detect the cognitive function. Electron microscopy was
used to determine the synapse numbers. The expression of SYN and GAP-43
was then quantified by immunofluorescence staining and Western blot
analysis. Compared with the standard housing, EE promoted the cognitive
function recovery in the mice with stroke. Moreover, EE increased the
synapse numbers and the expression of SYN and GAP-43 in both the
ipsilateral and contralateral hemispheres (
P < 0.05). A
further correlation analysis revealed a positive correlation between the
cognitive function outcomes and the relative expression of GAP-43 and
SYN. Furthermore, the correlation of the expression of GAP-43 and SYN
with cognitive function was higher in the contralateral brain than in
the ipsilateral brain. In conclusion, an EE may promote cognitive
function
via bilateral synaptic remodeling after cerebral
ischemia. Also, the contralateral brain may play an important role in
the recovery of cognitive function
