Increased Plasma Cortisol Levels Associated With Alzheimer Progression
March 1st 2007Increased plasma cortisol levels (correlated with increased hypothalamic-pituitary-adrenal axis activity) may be associated with more rapid disease progression in Alzheimer-type dementia (AD). In a study conducted at the Washington University School of Medicine in St Louis, Dr John Csernansky and colleagues assessed 33 patients with very mild or mild AD and 21 persons without AD annually for up to 4 years, using the Clinical Dementia Rating Scale and various neuropsychological tests. Plasma was obtained from each patient and assessed for cortisol level.

Comorbidity of Bipolar and Panic Disorders and Its Consequences
March 1st 2007Panic disorder occurs in about 1 in 5 individuals who have bipolar disorder. Anxiety amplifies the distress caused by depression and mania, but pharmacological approaches are tricky and under-studied. Frequent comorbidity and evidence of a possible genetic relationship of bipolar and panic disorders are suggestive of a causal relationship between the 2. Thus, it may be fruitful to look more closely at evidence for common biological abnormalities in both disorders to find a pathophysiological mechanism that links mania, depression, and panic attacks. Mood episodes and panic attacks can both be modeled as the result of deficits in amygdala-mediated emotional conditioning. From this model, some insight may be gained for potentially helpful treatment strategies for the 2 disorders when they occur together.

The Impact of Abnormal Insulin Levels on Cognitive Function in Older Adults
November 1st 2006By now, many clinical researchers and practitioners recognize the strong association between cognitive impairment and type 2 diabetes, which, in its early stages, is characterized by hyperinsulinemia and insulin resistance. Although this relationship has not been observed uniformly, more than 20 large-scale epidemiologic studies have reported a link between type 2 diabetes and in creased risk of cognitive impairment and dementia, including Alzheimer disease (AD), the most common type of dementia.

Pinpointing the Cause of Non-Alzheimer Dementia
November 1st 2006Many 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.

Since its initial description by Kahlbaum (1828-1899) over a century ago, catatonia has been associated with psychiatric, neurologic, and medical disorders. Contemporary authors view catatonia as a syndrome of motor signs in association with disorders of mood, behavior, or thought. Some motor features are classic but infrequent (eg, echopraxia, waxy flexibility) while others are common in psychiatric patients (eg, agitation, withdrawal), becoming significant because of their duration and severity.
