Study explains why a moody gut often accompanies depression

Mice with a genetic mutation linked to severe depression had impaired ability for neurons in the gut and brain to create serotonin. The reduction of serotonin in the gut led to a deterioration in the gut's lining, slowing the movement of contents through the GI tract and resulting in constipation. However, treatment with 5-HTP increased neurogenesis in the gut, restoring normal function.... Read More...

Possible link between autism and antidepressants use during pregnancy: Mouse Study

A new study in mice reveals a possible link between the use of SSRI antidepressants during pregnancy and an increased risk of autism-like symptoms in offspring. Offspring exposed to fluoxetine (Prozac) in utero were more likely to exhibit impaired neurotransmission caused by an overactive serotonin receptor in the prefrontal cortex, an area of the brain implicated in modulating social behaviors. However, treating the mice with a compound that blocks the receptor alleviated the behavioral problems and improved working memory.... Read More...

Fish are accumulating certain antidepressants, antibiotics and sun cream components

Antidepressants, such as the SSRI amitriptyline, antibiotics associated with developmental problems and sun cream components are contaminating water, and are being accumulated in fish. Exposure to the medications has effects on the molecular level to the fish. Researchers say this poses a problem as consumption of gilt-head bream is on the rise, and there could be a risk of the contaminants reaching humans via diet.... Read More...
