This optimistic book about recovery of function
after brain injury or disease is written by three neuroscientists
specifically to counter the belief that brain injury is
permanent and that the brain cannot be repaired. They point
out that this belief leads to often inappropriate or no
treatment, which then makes it a self-fulfilling prophecy.
However there is an increasingly extensive body of evidence
from laboratories around the world that given the right
conditions and specific chemicals, for example, normal
function can be restored. This literature is highly specialized,
highly technical, and often apparently unrelated to human
recovery. It is also produced at a prodigious rate. According
to a 1989 survey, fact-based knowledge doubled every 18
months at that time, and it was predicted that by the year
2010 it will double every 4 weeks. It is not surprising,
therefore, that members of a health-professional team have
difficulty keeping up with the clinical rehabilitation
literature, and that they do not have the time or the energy
to read studies on laboratory animals or tissue studies
which are not seen as high priority or of relevance to
their work.
