A new study adds to the growing body of research linking inflammation to depression. Researchers found the molecule histamine directly inhibits the release of serotonin in the brain by attaching to inhibitory receptors on serotonin neurons in mice.
Researchers report histamines can help improve memory of objects up-to 25 days longer than normal in mice, as well as improving people's long term memory test scores. The study suggests taking histamines may help alleviate symptoms of memory disorders such as Alzheimer's and other dementias.
Histamines may help to reduce tics associated with Tourette syndrome, a new mouse study finds.
