Rehabilitation After Stroke from Germany

A good explanation of how Germany does rehabilitation.
I did like this paragraph on brain reserve, which I want more research on, so I can increase my brain reserve again so I survive my next one. new word - leukoaraiosis
The decisive factor
here is the brain’s reserve capacity, i.e., the absence of
pre-existing damage in the form of subclinical vascular
lesions. Accordingly, persons who had led an active
lifestyle till just before the stroke (7) and those with no
more than a minor degree of leukoaraiosis (pre-existing
white-matter damage) have been found to recover particularly
well from stroke. In fact, the beneficial effect
of not having leukoaraiosis is of comparable magnitude
to that of thrombolysis. Thus, pre-existing brain
damage is more important than age as a determinant of
the chance of recovery (8)

Where is something similar for the US?, the ASA or NSA are falling down on their mission statements.
