This article reviews the antidepressant actions of ketamine, an N-methyl-D-aspartame glutamate receptor (NMDAR) antagonist, and offers a potential neural mechanism for intranasal ketamine's ultra-rapid actions based on the key role of NMDAR in the nonhuman primate prefrontal cortex (PFC). Although intravenous ketamine infusions can lift mood within hours,(More)
A growing body of evidence supports the hypothesis that exposures that damage or disrupt the developing central nervous system are associated with schizophrenia and related disorders (McGrath and Murray 2003). Associations for some prenatal exposures have now been replicated—for example, nutritional deprivation (St. Clair et al. 2005; Susser et al. 1996).(More)
Schizophrenia is a severe mental disorder of unknown etiology. Recent reports suggest that a number of environmental factors during prenatal development may be associated with schizophrenia. We tested the hypothesis that environmental lead exposure may be associated with schizophrenia using archived serum samples from a cohort of live births enrolled(More)
Schizophrenia and related disorders are adult-onset illnesses with no definitively established risk factors. Several studies report that exposures to infection and nutritional deprivation during early development may elevate the risk of later developing schizophrenia, specifically during the prenatal period. Preliminary evidence implicates lead exposure as(More)
BACKGROUND Approximately 21% of US children age 9 to 17 have a diagnosable mental illness with some degree of impairment. As early-onset mental illness may persist throughout the life span, effective primary mental health prevention programs are of paramount importance. METHODS We conducted a literature review of various preventive programs targeting(More)
A meta-analytic study of reports of brain tumors and psychiatric symptoms for the past 50 years was conducted to examine potential associations between tumor location and psychiatric symptoms. Results demonstrated that there is a statistically significant association between anorexia symptoms and hypothalamic tumors. For the rest of the brain regions a(More)
While second-generation antipsychotics treat negative as well as positive symptoms, recovery for persons with schizophrenia remains elusive, in part because there are no FDA-approved medications that treat the cognitive deficits of schizophrenia (CDS). Recent work has identified agents that, when added to antipsychotics, improve cognition in schizophrenia.(More)
The Symptoms of Trauma Scale (SOTS) is a 12-item, interview-based, clinician-rated measure that assesses the severity of a range of trauma-related symptoms. This pilot study evaluated its use and psychometric properties in an outpatient setting that provides treatment to survivors of chronic interpersonal trauma. Thirty participants completed self-report(More)
