End of the Cartesian era: the evidence linking somatic and psychiatric disorders
background Patients in the twentyfirst
century are not best served by a medical system
based on a cartesian split of somatic and mental
health. The first reason is that models of
ontogenesis of psychiatric and somatic disorders
are showing convergence - both are considered
outcomes of vulnerabilities that are programmed
early in life, the further expression of which is contingent
on environmental exposures interacting
with (epi)genetic factors.
aim Recent work suggests that pathways
to somatic and psychiatric disorders are shared to
a degree, as evidenced by research showing that
factors typically associated with psychiatric disorders,
such as childhood trauma and trait-anxiety,
also predict somatic disorders whilst somatic
alterations in for example the immune system
have been associated with a range of psychiatric
disorders.
methods Thus, it is attractive to
hypothesise that dysregulation of central control
of basic somatic and mental processes may become
pleiotropically expressed across a range of systems.
The second reason is that patients do not
experience separate somatic and mental health
areas of health - their experience is unitary and
unmet health care needs are unlikely to be met by
a system that is fractured and does not take into
account their health experience at the most basic
level.
results MedPsych units can be seen as a
means to upgrade the outdated cartesian system
found in most hospitals to a system that can cater
for patients whose expression of ill-health requires
a concerted and integrated approach from somatic
and mental health specialists.
conclusion Over the last 10 years, the
MedPsych unit in mumc has gradually found a
position from which integrated care can be organised
and carried out effectively, albeit in a still
limited fashion.
