Foreword
The recent interest in the relationship between the gut and well-being has been an
intriguing development within, till recently, the biosciences. Interestingly, from
that perspective, the focus has been largely in the area of physical well-being.
However, this is changing as the relationship between the gut and the brain, which,
though undeniably complex, begins to present compelling evidence for a significant
relationship with mental health. This is important as it allows us to consider the
emergence of some mental health problems in a novel way and allows us to contrast
this new evidence with existing models, irrespective of whether they be medical,
psychosocial or genetic models. A fundamentally exciting position also presents itself
with this emerging evidence base of the gut–brain axis for those of us working within
the clinical sphere, and that is the potential for interventions that may be effective and
also benign, particularly when one considers the side-effect profile that is associated
with many of the pharmacological interventions used within the mental health field.
The area of probiotics and mental health thus represents a comparatively new field, a
science in its infancy and yet, even at this early stage of evolution, finding novel and
robust outcomes with significant implications for potential intervention strategies.
Reflecting on the potential role of probiotics to help with mental health problems
provides a seductive context for a number of potential ‘thought experiments’. It is
thus plausible to consider in a scientific and robust way, the relationship between the
gut–brain axis and the manifestation of significant mental health problems within
an aetiological perspective. Thus, if we are able to establish a relationship between
for example, the gut–brain axis and depression, what does this mean in terms of
diagnosis, course and outcome? Given the complexity of diagnostic systems used
within clinical psychiatry, could this be considered a unitary model of depression,
embracing all accounts of diagnosed depression, or could this be the context to define
a new type of depression, with a different cause, treatment and outcome, to say,
for example, an endogenous depression defined within an aetiological model of low
5-Hydroxytriptamine (serotonin) levels, which would of course would likely define
a pharmacological intervention approach, usually with selective serotonin reuptake
inhibitors (SSRI’s). Considering just this single premise then, a constellation of
pertinent factors begins to emerge regarding, diagnosis, course and prognosis.
The above presents just one potential possibility that the area of probiotics
and mental health brings in facilitating innovation and renewal in the provision of
evidence-based mental health care. A second exciting possibility is that through
effective patient education in the link between the gut–brain axis and mental health
