A new study has revealed that blueberries may help treat post-traumatic stress disorder (PTSD).Ebenezer et al. have previously demonstrated that SSRIs increase levels of serotonin (5-HT) and the neurotransmitter norepinephrine (NE) and that the increased NE might reduce the effectiveness of SSRI therapy.

In the new study, researchers at Louisiana State University looked at the ability of blueberries to modulate neurotransmitter levels in a rat model of PTSD. Researchers supplemented some of the rats with a blueberry-enriched (2 percent) diet and others with a control diet. A third control group did not have PTSD and received a standard diet (without blueberries).
 
They found that PTSD rats who did not receive blueberries demonstrated a predictable increase in NE and 5-HT when compared with the control group. However, the PTSD rats that received blueberries showed a beneficial increase in 5-HT with no effect on NE levels, suggesting that blueberries could effectively modulate neurotransmitters in PTSD.
 
These findings indicated that non-pharmacological approaches might modulate neurotransmitters in PTSD. Further studies to understand the molecular mechanism of neuro-protection by BB could provide a potential therapeutic target for the treatment of PTSD.
