"Mental disorders are [most frequent in American adult populations--3.7% of all people annually]--and are [even higher in Hispanic/Latino and African-American populations]--so the prevalence rates for mental disorders within the United States should be measured and adjusted to eliminate racial discrimination. Researchers and practitioners, especially in primary care settings are using mental disorder rates to improve the quality of care for their patients and to quantify the mental health needs of Americans." - Anonymous Online Contributor

What is the primary cause of mental disorders?

"There are differences of the prevalence of the mental disorders depending of gender, age and educational level. In our study we found out that alcoholism causes the strongest mental disorders in women younger and older than 40 years while the main mental disorder cause was anxiety. Depression and schizophrenia are more common among men younger and older than 40 years." - Anonymous Online Contributor

Unverified Answer

How does lorazepam and fmri work?

"A significant increase in response to task-modality stimuli occurs after single intravenous doses of lorazepam. This effect is blunted by administration of a second dose of lorazepam. Lorazepam seems to work by altering processing of mental information during the course of a task in terms of response speed and reaction time, indicating that psychopharmacology might alter neural substrates during cognitive tasks." - Anonymous Online Contributor

Has lorazepam and fmri proven to be more effective than a placebo?

"The current study suggests that lorazepam was significantly more effective than a placebo in reducing anxiety levels in patients with insomnia. This is evident in all subjective assessments of insomnia symptoms and the EDSS score." - Anonymous Online Contributor
