One hundred eleven mildly to moderately insomniac patients participated in a double-blind, placebo-controlled study to establish the efficacy of diphenhydramine as an over-the-counter (OTC) sleep aid. A two-week crossover design was employed in which all patients received both diphenhydramine and placebo for one week each. The daily diphenhydramine dose was 50 mg at bedtime. Results obtained indicate that diphenhydramine improved various sleep parameters, including sleep latency, to a significantly higher degree than did placebo. In addition, patients on diphenhydramine reported feeling more restful the following morning and patients preferred the diphenhydramine drug to placebo despite experiencing more side effects. This study thus supports the use of 50 mg diphenhydramine as an OTC sleep aid in the treatment of temporary mild to moderate insomnia.
Posttraumatic stress disorder has long been linked to violent behavior. However, the exact nature of that association remains poorly characterized due to the limitations of knowledge in the area of phenomenology, contextual factors, the biology, and the nature of the aggression involved in the disorder. A clear understanding of the genesis of violence in posttraumatic stress disorder can be helpful to those involved in assessing psychiatric-legal issues relevant to the disorder and in its therapeutic management. In this article, we review the potential psychological links between post-traumatic stress disorder secondary to combat exposure and violent behavior and suggest a tentative classification of the main psychological causes of violence in that syndrome.
Dangerousness in the delusional misidentification syndromes is studied by reviewing a sample of 82 cases defined by either verbal threats or physical violence caused by a misidentification delusion. Eighty cases were obtained from a review of the anglophone psychiatric literature in which the patients exhibited some degree of dangerousness, to which we added 2 previously unreported cases.
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.
