New research adds to the growing work linking an infection caused by the Toxoplasma gondii parasite to suicide attempts. About 10-20 percent of people in the United States have T. gondii, in their bodies.
Through a combination of genetic and psychological testing, researchers have identified factors that mitigate against PTSD. In combat, soldiers who avoided threats were more likely to develop PTSD as a result of traumatic experiences, the study found.
Researchers analyze the atomic structure of two types of human serotonin receptors. Their findings could explain why some drugs, which interact with these receptors, occasionally have harmful effects.
A synthetic compound, decynium-22, is able to turn off SERT in the brain, enhancing the effectiveness of SSRIs.
A new study confirms MDPV, a recreational drug commonly known as "bath salts", could be more addictive than methamphetamine.
Researchers discover a low dose of psilocybin erased conditioned fear responses in mice. They suggest the agent could be a potential treatment for PTSD and related conditions.
Researchers suggest serotonin metabolism in the pineal gland could play a role in the underlying cause of depression. The findings were based on biochemical changes which were seen to be in association with improvements in depression.
Researchers identify a molecular pathway which accelerates the time taken for antidepressants to work in mouse models.
Researchers find a genetic component to pro-social behavior is also linked to social anxiety.
