Reelin is a secreted extracellular matrix protein approximately 410 kDa mol. wt that is reduced in brains of patients with schizophrenia, autism, bipolar disorder and major depression. Recent reports also indicate its near absence in sera of some patients with an autosomal recessive form of lissencephaly. Moreover, Reelin is involved not only in normal cortical lamination of the brain during mammalian embryogenesis but is also implicated in cell signaling systems subserving cognition in adult brain. Here, we show that blood levels of Reelin and its isoforms are altered in three psychiatric disorders, namely, schizophrenia, bipolar disorder and major depression. The changes include significant increases in 410 kDa Reelin moiety of 49% in schizophrenic patients (p < 0.022) of four ethnic compositions (Caucasian, Vietnamese, Hmong and Laotian) and non-significant increases in depressed patients by 34% vs control blood. In contrast, 410 kDa Reelin levels decreased by 33% in bipolar blood, albeit non-signficantly, vs. controls. There was a significant increase of 90% (p < 0.0061) in 330 kDa Reelin in Caucasian schizophrenics; the depressed value was elevated by 30% vs. control but non-significantly. Again, in contrast, bipolar 330 kDa value decreased by 31% vs control (p < 0.0480). Finally, all 180 kDa Reelin values varied minimally in schizophrenics vs controls. In contrast, the 180 kDa Reelin values dropped significantly by 49% (p < 0.0117) and 29% (p < 0.0424) in bipolar and depressed patients, respectively, compared with controls. The alterations in blood Reelin values appear to be specific since levels of two other blood proteins, ceruloplasmin and albumin did not vary significantly between all psychiatric subjects and controls. These findings suggest that blood Reelin levels and its isoforms may be used as potential peripheral markers to diagnose presence of several psychiatric disorders and may also serve as targets for future therapeutic interventions.
War trauma experienced in childhood, early malnutrition from famines, head trauma, and excess Khat use in male adolescents provide partial explanations for the large number of young psychotic Somali men seen in the clinic from 2001 to 2009.
There has been increased philosophical, psychological, and, more recently, psychiatric interest in the moral emotions, most specifically the emotions of guilt, shame, regret, and remorse. Interest in these emotions has not been in their role as symptoms of a particular mental illness, but in their presence in everyday life and in their importance in defining our character and our very humanity. Moral emotions are those emotions that arise in the context of life experiences and daily choices that bear upon our perceptions of the rightness or wrongness of particular actions or inactions. Human beings have a moral scanner that constantly provides both a cognitive judgment and a feeling tone of ease or unease in the moral evaluation of life's moment-to-moment activities. This paper discusses the intersection of psychiatry and the moral emotions, providing case examples and a review of empirical studies to illustrate the relevance of patients' concerns about their moral choices to psychiatric evaluation and practice.
Among the respondents to the questionnaire, slightly more than half used no-suicide contracts, indicating that such contracts are not universally accepted as standard practice among these psychiatrists. More data are needed to determine the effectiveness of no-suicide contracts in preventing suicide.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
