New findings may lead to treatment for anxiety in Rett Syndrome

The classic form of Rett Syndrome (RTT) shows us a child who is the picture of anxiety: she wrings her hands, hyperventilates, trembles. The sinister progression of the disorder, which usually begins to manifest between the ages of 6-18 months, includes loss of acquired skills, speech and mobility, sometimes an autistic-like withdrawal, sometimes months of inconsolable crying.

Studies suggest new brain protein may help in treating schizophrenia, insomnia and anxiety

Pittsburgh, June 22 A small protein in the brain that has only recently been discovered and, paradoxically, induces both profound wakefulness and a less anxious state, may represent a novel target for the treatment of psychotic behavior and schizophrenia, according to new research presented at the 6th International Congress of Neuroendocrinology (ICN 2006). ICN 2006 is being held at the David L....

Oxytocin raises aggression, cuts anxiety during lactation; similar effects on virgin rats

STEAMBOAT SPRINGS, Colorado (July 18, 2005) Maternal aggressive/protective behavior is recognized throughout mammalian species, especially during lactation. When hiking, we warn our kids not to approach bear cubs, or to get between a cub and the mother. While driving and you see a fawn, you know a doe can't be too far away and will run headlong to protect it....... The same neurohypophyseal (NH)...

Histamine, anxiety and alcoholism

In the brain, histamine regulates a wide variety of physiological processes, including water and food intake, sleep-wake cycles, endocrine homeostasis, locomotion, and memory and learning. In a new study, researchers have found that decreased levels of brain histamine, which are associated with a functional polymorphism of histamine N-methyltransferase (HNMT) called Thr105 allele, may also resul...
