And the researchers think they know why - in short, a unique white blood cell that functions as a go-between for the brain, immune system and gut.
The good news is the team also
discovered two remedies which can reverse the damage.
How the Gut Affects
Memory and Brain Health
When compared to the control mice, those who lost their healthy bacteria performed worse in memory tests, and the production of new brain cells (neurogenesis) stopped within the hippocampus.
The team ran a subsequent experiment, where they compared untreated mice to mice who had healthy gut bacteria, but low levels of Ly6Chi - either due to genetics or administered antibodies that destroy white blood cells.
What they found is that mice with low Ly6Chi displayed the same memory and neurogenesis problems as the mice in the previous study who had lost gut bacteria.
Moreover, when researchers replaced Ly6Chi into mice treated with antibiotics, their memory and neurogenesis improved.
As luck would have it, the problematic side effects of antibiotics can be reversed.
When mice were given probiotics or exercised on a wheel after receiving antibiotics, they regained their memory and neurogenesis.
Interestingly, when the mice were given a fecal transplant (which helps to recolonize broad gut bacteria), the team did not see an improvement in brain cell health, as with the probiotic treatment.
The findings of the study are yet
another reason as to why antibiotics should be used judiciously -
and reserved for only the most serious infections.
The Centers for Disease Control (CDC) director Tom Frieden has warned of "nightmare bacteria" that have developed due to the overuse of antibiotics, resulting in strains which can cause fatal, untreatable infections.
Some of the most dangerous antibiotic-resistant strains include:
One of the more disturbing developments in recent years is NDM-1, otherwise known as "New Delhi metallo-beta-lactamase 1" - a bacterial gene that transfers "super-resistance" to conventional antibiotics.
According to Dr. Joseph Mercola:
The CDC stresses that antibiotics are useless for illness caused by viruses - like colds, influenza, most sore throats, bronchitis, and many sinus and ear infections.
Regrettably, antibiotics have historically been prescribed by physicians for these ailments in an attempt to avoid secondary bacterial infections.
Furthermore, one of the most significant
causes of antibiotic-resistant bacteria is their enormous overuse
by the agricultural industry, where 24.6 million pounds
of antibiotics are given to livestock each year.
