To identify rates of and risk factors for psychiatric diagnosis preceding the diagnosis of neurodegenerative disease. ⋯ Neurodegenerative disease is often misclassified as psychiatric disease, with behavioral-variant frontotemporal dementia patients at highest risk. While this study cannot rule out the possibility that psychiatric disease is an independent risk factor for neurodegenerative disease, when patients with neurodegenerative disease are initially classified with psychiatric disease, the patient may receive delayed, inappropriate treatment and be subject to increased distress. Physicians should consider referring mid- to late-life patients with new-onset neuropsychiatric symptoms for neurodegenerative disease evaluation.

Given the complex relationships between fibromyalgia and major depressive disorder (MDD), it has been suggested that fibromyalgia is a "masked" MDD. In experimental settings, fibromyalgia is associated with lowered pain thresholds (hyperalgesia) and deficient pain inhibition. Similarly, it has been recently proposed that the proneness of patients with MDD to develop chronic pain results from a deficit in pain inhibition. This cross-sectional study measured experimentally induced pain perception and inhibition in patients with MDD and patients with fibromyalgia. ⋯ Our results suggest that (1) fibromyalgia and MDD are both associated with signs of hyperalgesia, (2) hyperalgesia is more pronounced in fibromyalgia, and (3) the deficit of pain inhibition is specific to fibromyalgia. As such, these results suggest that there is an overlap between fibromyalgia and MDD, but that fibromyalgia can be distinguished from MDD in terms of DNIC efficacy.

Strategies for selecting treatment and mitigating risk in patients with chronic pain.
Although opioid analgesics treat more types of pain and are usually more potent than other classes of analgesics, opioids are ineffective for some patients and can cause adverse physiologic or psychiatric effects in others. If a prescriber determines that opioid treatment is appropriate for a patient, opioid medications can be used chronically with both effectiveness and safety. Responsible opioid prescribing requires risk management, including assessing patients for abuse risk, identifying and measuring functional outcomes, and monitoring for adverse medication effects. Prescribers should follow the Federation of State Medical Boards model policy for using controlled substances and transparently document risk management when treating pain.

To examine the prevalence of chronic major depressive disorder (CMDD) and dysthymic disorder, their sociodemographic correlates, patterns of 12-month and lifetime psychiatric comorbidity, lifetime risk factors, psychosocial functioning, and mental health service utilization. ⋯ Individuals with CMDD and dysthymic disorder share many sociodemographic correlates, comorbidity patterns, risk factors, and course. Individuals with chronic depressive disorders, especially those with dysthymic disorder, continue to face substantial unmet treatment needs.

Suicidal ideation is a medical emergency, especially when severe. Little research has been done on pharmacologic interventions that could address this problem. Ketamine, an N-methyl-D-asparate antagonist, has been reported to have antidepressant effects within hours. We examined the effects of a single dose of ketamine on suicidal ideation in subjects with treatment-resistant major depressive disorder (MDD). ⋯ Suicidal ideation in the context of MDD improved within 40 minutes of a ketamine infusion and remained improved for up to 4 hours postinfusion. Future studies with ketamine in suicidal ideation are warranted due to the potential impact on public health.
