The majority
of cerebral aneurysms are small,
unsymptomatic and
unlikely to
rupture.
However,
aSAH is a
life-threatening
condition,
which
can
leave
patients
with profound
physical
and cognitive
deficits.
Modifiable
risk factors
include smoking, hypertension
and excessive alcohol intake.
Healthcare
professionals
have an
important role,
through
public health education,
in reducing the
incidence of aSAH.
