Decreased plasma nesfatin-1 levels in patients with generalized anxiety disorder.

Nesfatin-1, a recently discovered satiety molecule, is localized in neurons of the hypothalamus and brain stem and colocalized with stress-related substances. However, the relation between nesfatin-1 and stressor related behaviors like anxiety and/or fear has not yet been investigated in human subjects. In the present study, our aim was to investigate whether there was a relationship between plasma nesfatin-1 levels and generalized anxiety disorder.

Psychopathological profile of patients with different forms of bruxism.

The aim of the current study was to evaluate the prevalence of psychopathological symptoms in patients who self-reported different forms of bruxism by means of clinical and anamnestic diagnostic criteria. Eighty-five participants were divided into four groups as sleep bruxers (12), awake bruxers (24), sleep-awake bruxers (33), and non-bruxers (16). A self-report symptom inventory questionnaire (Symptom Checklist-90-Revised (SCL-90-R)) was filled out by all groups to determine their psychopathological symptoms.
