Patients with PD may be at more than twice the risk for the development of malignant melanoma than the general population, according to research by John M. Bertoni, MD, PhD, professor and chair of the Department of Neurology at Creighton University, Omaha, and colleagues.1 He presented the results of this research at the American Neurological Association's 131st Annual Meeting this past October in Chicago.

To evaluate the degree to which newer antipsychotic agents are implicated in parkinsonism and whether drug-induced parkinsonism (DIP) is being adequately recognized, Christine D. Esper, MD, clinical instructor in neurology, and Stewart A. Factor, DO, professor of neurology at Emory University in Atlanta, performed a retrospective review of 354 consecutive patients in whom parkinsonian symptoms were newly diagnosed at a movement disorders clinic in 2004-2005

In a recent article on genetic counseling in psychiatry, Christine Finn, MD, and Jordan W. Smoller, MD, ScD, noted that family and twin studies have documented the familiality and heritability of schizophrenia, bipolar disorder, major depression, anxiety disorders, autism, attention-deficit/hyper- activity disorder (ADHD), and Tourette syndrome, among others, and that molecular genetic studies have begun to identify possible susceptibility loci for several of these disorders, most notably schizophrenia.

It may come as a surprise, especially given its low repute in the popular mind since the 1980s, but electroconvulsive therapy (ECT) is making a comeback, both as a recommended treatment for depression and in public awareness.

Prevalence of depression in PD is estimated to range from 7% to 76%. The variation is largely attributed to the diversity of the populations under study, differences in the definition of depression, and the fact that some studies used point prevalence and other studies used monthly prevalence. Also, the prevalence of depression varies with fluctuations of cognitive status and other comorbidities that are an integral part of PD.

Effective antiepileptic therapy depends on balancing seizure control and tolerability, said Manoj Raghavan, MD, PhD, during a presentation at the midyear meeting of the American Epileptic Society in Chicago this past June. Tolerability places a ceiling on how far you can go in controlling seizures using medications alone, he commented.

Many physicians, including psychiatrists, may shy away from seeing elderly patients with symptoms of dementia because they imagine that there are a large number of alternative diagnoses and that differential diagnosis is complicated. In fact, however, the number of possible diagnoses in most situations is relatively small and the diagnosis of dementia in older patients is certainly feasible in primary care psychiatry.

The setting of a fast-paced emergency department (ED) or psychiatric emergency service makes it especially difficult to sensitively elicit and address an individual patient's needs and concerns. When considering the myriad differences in culture that come into play between a patient and a psychiatrist or other mental health care clinician, optimal diagnosis and treatment can be even more challenging, as the cases described here illustrate. The important influence of culture cannot be stressed enough. Taking the time to understand "where the patient is coming from" can prevent an already stressful, highly emotionally charged situation from becoming even more convoluted.

The editors of Pediatric Neuropsychiatry must have drawn on their experiences and the feedback they received on their first book, Textbook of Pediatric Neuropsychiatry (American Psychiatric Press, 1998), for this text.

Typically, delirium worsens at night ("sundowning"), with lucid intervals often present in the morning. It is important to realize that delirium may appear before any abnormal laboratory values are detected and may persist after the resolution of these abnormalities.

Complaints of persistent memory loss in otherwise well-functioning individuals after recovery from a psychiatric illness through electroconvulsive therapy (ECT) are best viewed as a conversion reaction or a somatoform disorder. The Camelford experience is a model for the complaints of ECT's profound personal memory losses.

Agitation in the Elderly

While dementia is marked by such cognitive deficits as disorientation, memory loss and changes in intellectual functioning, these are not the symptoms that cause the most distress to caregivers.
