Hoarding

November 01, 2007

Article

Many of the things that we busy ourselves with have no apparent utility. Blogging, playing games, and collecting come to mind. To declare that we are compelled to do these things may be too strong, but we do pursue these activities with little deliberation and without concern as to their usefulness. The ubiquity of these pursuits suggests that these activities or their variants helped humans survive at some point and that they now rest on innate brain programs.

Ameliorating Stressors May Alleviate MS

August 01, 2007

Article

For 2 decades Maggie McPhersun's physicians had attributed her fatigue, episodes of choking, and periodic imbalance and numbness to chronic fatigue or depression.

April 01, 2007

Article

Depression and cognitive impairment are common in patients with multiple sclerosis (MS) but often are overlooked.

Broken Sleep May Be Natural Sleep

March 01, 2007

Article

Once again your patient, an accountant and tax specialist, is complaining about his sleep. More nights than not he awakens at about 2 am. An hour goes by, sometimes 2, before he returns to sleep. You've prescribed 4 different hypnotics. Each gave the same unsatisfactory result. For 2 weeks, your patient got the 8 hours of uninterrupted sleep he-and you-seek, but then the old pattern returned. Following your instructions, he avoids caffeine, doesn't exercise after 6 pm, and confines his activities in bed to sleep, but to no avail. You refer him to a sleep laboratory, and the results there are entirely consistent with what he's been telling you. In the sleep lab he falls asleep at 11 pm, awakens at 2:30 am, returns to sleep at 4 am, and awakens for good at 7:30 am. He does not have sleep apnea, restless legs syndrome, or depression.

Ketamine and NMDA Receptor Antagonists for Depression

February 01, 2007

Article

In recent months, it's been the rare week that doesn't come with a report about the dangers of antidepressants. These drugs do have their drawbacks, but the dangers they pose are not their main problem. Their biggest shortcoming is that they don't work very well; fewer than half of the patients treated with them get complete relief, and that relief takes an unacceptably long time 2 o 3 weeks t kick in.

Finessing the Fine Line Between Pain Management and Opioid Addiction

Article

Up to 30% of patients for whom opioids are prescribed for chronic pain show an escalating pattern of opioid abuse characterized by taking more opioids than prescribed, seeking early refills, and finding additional sources of opioids. Although many of these drug-seeking patients are addicted to opioids, some are suffering not from addiction but from inadequate pain management, according to Martha Wunsch, MD, chair of Addiction Medicine and associate professor of pediatrics at Edward Via Virginia College of Osteopathic Medicine (VCOM) in Blacksburg.

Depression in Parkinson Disease

November 01, 2006

Article

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.
