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.
Alzheimer dementia (AD) represents a profound global health concern. By the year 2050, the prevalence of AD in the United States is expected to reach 15 million. At present, there are 4.5 million cases in the United States, which equals an estimated cost of $100 billion each year in medical and family expenses.
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.
A possible link between diabetes and cognitive dysfunction, specifically Alzheimer disease (AD), is becoming increasingly apparent. Indeed, compared with AD risk in healthy persons, the risk of AD development is 65% to 100% greater in persons with diabetes.
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.
Your patient has pain and numbness that extends from the shoulder to the hand. You suspect a herniated cervical disk, but the MRI scan comes back normal. What else could the culprit be?
A review of the book, "Principles and Practice of Geriatric Psychiatry."
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.
The obvious sometimes bears repeating: Sick people have trouble thinking. They may be suffering from a delirium, a dementia or a more subtle disturbance of cognition caused by fever, drugs, infection, inflammation, trauma, hypoxemia, metabolic derangement, hypotension, tumor, intracranial pathology, pain and so forth.
Can sociodemographic and clinical variables predict outcome in cases of schizophrenia? Results from studies related to prognostic variables for schizophrenia have yielded interesting yet inconsistent results.
With an application to certify its use in depression before the FDA, transcranial magnetic stimulation (TMS) has become a hot topic in the expanding field of device-based treatment modalities.
The following 3 cases illustrate the diagnostic challenges related to differentiating brain injury and posttraumatic stress disorder (PTSD) in patients presenting to the emergency department (ED) in the acute period following a traumatic injury. Such patients pose a dilemma for ED clinicians because of the interplay between head injury and PTSD in the clinical presentation of cognitive impairments in the aftermath of trauma.
Any survivor of a traumatic event is at increased risk for the development of a stress disorder. Considering the number of persons affected by events related to the global war on terrorism and several recent large-scale natural disasters, it seems inevitable that the number of persons who will experience a stress disorder will increase. It is also probable that many of these persons will at some point seek treatment in or be brought to an emergency department (ED).
The presentation of patients to the emergency department following trauma is often complicated by the behavioral reaction to the accident that brought them there. In some cases, the mental reaction to psychological trauma is the primary presenting phenomenon. ED physicians and staff often use medication to treat the acute effects of psychological trauma. However, there is little empiric evidence to support this practice.
The prevalence and debilitating nature of some of the personality disorders has impeded the study of psychopharmacology in these conditions. However, important advances have been made in the last several years.
This article focuses on data concerning the efficacy of mood stabilizers in the treatment of BPD.
Antidepressants may have a protective effect on the hippocampal atrophy seen in patients with severe, untreated depression. This atrophy may be caused by an overabundance of glucocorticoids.
