The management of elder mistreatment: the physician's role.

The physical abuse, psychological abuse, exploitation, and neglect of older adults constitute a serious and under-recognized public health problem throughout the world. Clinicians often misinterpret the health effects of elder mistreatment (EM) as caused by underlying disease or the aging process. Clues to mistreatment include the patient's appearance, recurrent urgent-care visits for the same diagnosis, missed appointments, suspicious physical findings, and implausible explanations for injuries. Avoiding confrontation and emphasizing treatment of abuse-related health conditions help the clinician maintain a therapeutic alliance with the victim and abuser. Victim safety should be the paramount concern. Victims with decisional capacity should be apprised of the chronic, progressive nature of EM. Clinical strategies to stop abuse include hospitalization and closer monitoring through office visits and home nursing. In most U.S. states, laws require that clinicians report at least physical abuse to the local adult protective services agency or to law enforcement. Mandated reporting, while offering potential social and legal remedies, raises ethical concerns regarding the physician-patient relationship.

Motor dysfunction and risk for schizophrenia.

Motor dysfunction is associated with schizophrenia, and recent longitudinal studies indicate that it precedes the onset of clinical symptoms. Of particular interest is the heightened occurrence of involuntary movements, which are apparent as early as infancy and suggest the presence of subcortical brain abnormalities. In this article, we present the results of a study of spontaneous movements in adolescents with schizotypal personality disorder (SPD). SPD is a syndrome that has been shown to be genetically linked with schizophrenia and is often observed prior to the early adult onset of schizophrenia. Systematic coding of videotapes of diagnostic interviews revealed that the SPD group showed significantly more involuntary movements of the head, trunk, and upper limbs than did normals and adolescents with other personality disorders. There were no diagnostic group differences in the rate of voluntary movements. Salivary cortisol, measured before the interview, was positively correlated with involuntary movements. Taken together, the findings provide further support for the hypothesized etiologic relation between SPD and schizophrenia. Based on a neural diathesis-stress model, potential underlying mechanisms are discussed.
