Summary: “Implication
of Gut Microbiome in Brain Chemistry and Behavior” is an observation of the
roles of gut microbiome, and its effect on bodily, and brain health. The
article refers to advanced research techniques that link the gut’s microbiome
to the brain, behavior development, immune, metabolic, and physiologic
function. The study targeted weak microbiomes with Probiotic bacteria, such as
that found in yogurt, kefir, or Kombutcha. Scientists found chemical changes in
the brain with the administration of these beneficial bacteria, and observed
that brain functions such as levels of anxiety, mood, and memory were
positively affected. Further in the article, this is expanded with the
statement that “Researches have drawn links between gastrointestinal pathology
and psychiatric neurological conditions such as anxiety, depression, autism,
schizophrenia, and neurodegenerative disorders...” They also explain that such
symptoms can be the result of abnormal circumstances such as leaky gut, which
disrupts gut homeostasis, and allows bacteria to grow throughout the body with
minimum check. The study concludes with further support through animal testing,
linking the disruption of gut microbiomes in mice to levels of stress, anxiety,
and multiple neurotransmitters such as dopamine, and proteins involved in
neural synapse development. Much like with PRO-biotics, there are many strains
of bacteria. The article argues that determining the strain, genus, or species
of gut bacteria may eventually lead us towards finding more focused treatments.
The links between gut, and brain are still being explored today.
Reflection: This
article is extremely relevant to the knowledge we have gained on the importance
of gut homeostasis and how it relates to overall health. We know that disruption
of gut balance has much more than just a local effect on body function. When
the Gut Biome is out of balance, such as in a situation where one has taken
antibiotics; the gut must then be repopulated with beneficial bacteria or one
may experience elevated levels of anxiety, stress, or other (seemingly) non-gut
related cognitive affects. Antibiotics
are nondiscriminatory in their role. When we use such medicines, the harmful
bacteria we are targeting is removed, or reduced alongside the bacteria that
our body needs. This leads to a (voluntary) imbalance, which is usually in the
interest of the patient; but it is important to rebuild positive bacteria in
what is ultimately a new gut biome. I, myself have experienced anxiety, and
other cognitive changes as a result of an antibiotic course. With the help of
probiotics, I slowly saw many of these symptoms disappear, or improve as my gut
came closer to a healthy balance.
I also
believe that as Psych students, it is important to consider the role of the
gut, before turning directly to medicines (in cognitive cases). The nutrition
that we receive, and habits of gut health we practice go a long way in our
mental functioning, and much of the time; children, and students are not
consuming the correct foods to facilitate normative cognitive functioning. Many
doctors do not consider the patients diet when considering treatment and such an
oversight can lead to permanent damage that could ultimately be solved by
healthier eating habits.
This study offers many questions to be examined in patients with diseases being linked to poor gut biome. In future studies, it would be interesting to see if the onset of disease can be linked to a specific period of illness or drug treatment. It would also be interesting to investigate if certain illnesses or antibiotics could lead to the increase the risk for a specific disease such as schizophrenia.
