This monograph aims to provide a survey of recent research on the
pathogenesis of hypertensive encephalopathy. Or, in other words, to
relate experimental results directly to a clinical problem. I am
convinced that a very important task of experimental medical research is
to find applications to the relevant clinical problem as soon as
possible, and to avoid distraction by an increasingly over- whelming
accumulation of new information from all fields of scientific work. This
is undoubtedly easier for a clinician than for a scientist who is only
concerned with fundamental research; success- ful research for clinical
medicine thus requires that clinicians and scientific specialists in the
theoretical medical branches cooperate with each other. To fulfill this
aim the clinician must be able to think in pathophysiological terms to a
considerable extent, which will scarcely be possible if he is involved
in routine clinical medicine alone. Experimental work thus presents a
real challenge to the physician who wishes to solve a medical problem
and also possesses scientific curiosity. Besides an answer to his
question, he has the opportunity to obtain a real feeling for what he
has learned to call "physiologi- cal". I hope with my own experimental
work to provide a convincing example of how such work may serve as an
impressive reminder to the clinician of the possibly grave consequences
of underestimating a development in the course of a serious illness, for
instance a hyper- tensive episode following head injury.
