MENTAL DISORDERS DON'T HINDER HEADACHE TREATMENT

Contrary to long-standing thinking, medications may offer comparable headache relief to those with and without mental disorders.

For an especially miserable time, mix recurring headaches with depression, anxiety or both. But people in such a fix have cause for optimism, courtesy of a team led by psychologist Bernadette Heckman of Ohio University in Athens.

Drug treatments for headaches work just as well for patients with these psychiatric disorders as for those with no such problems, Heckman and her colleagues report in the November Pain.

Researchers and clinicians generally assume that the presence of one or more psychiatric ailments worsens headache symptoms and thus the prospects for successful treatment. Heckman and her colleagues conducted one of the few prospective studies to test that conviction.

“Contrary to conventional clinical wisdom, many patients with psychiatric disorders responded favorably to headache treatment,” Heckman says.

The team found that, during six months of treatment at any of four outpatient headache clinics, rates of improvement in headache frequency and intensity were about the same for patients with depression, anxiety, a combination of the two or no psychiatric disorders.

In a comment published with the new study, psychologist Todd Smitherman of the University of Mississippi in Oxford and psychiatrist Donald Penzien of the University of Mississippi Medical Center in Jackson say that the new findings “give us pause to reconsider our earlier predictions” that people with mental disorders respond poorly to headache treatment.

Why Antidepressants Don't Live Up to the Hype

In the '90s, Americans grew fond of the idea that you can fix depression simply by taking a pill — most famously fluoxetine (better known as Prozac), though fluoxetine is just one of at least seven selective serotonin reuptake inhibitors (SSRIs) that have been prescribed to treat hundreds of millions of people around the world.

But in the past few years, researchers have challenged the effectiveness of Prozac and other SSRIs in several studies. For instance, a review published in the Journal of Affective Disorders in February attributed 68% of the benefit from antidepressants to the placebo effect. Likewise, a paper published in PLoS Medicine a year earlier suggested that widely used SSRIs, including Prozac, Effexor and Paxil, offer no clinically significant benefit over placebos for patients with moderate or severe depression. Meanwhile, pharmaceutical companies maintain that their research shows that SSRIs are powerful weapons against depression. (Here's a helpful blog post that summarizes the debate.)

Now a major new study suggests that both critics and proponents might be right about SSRIs: the drugs can work, but they appear to work best for only a subset of depressed patients — those with a limited range of psychological problems. People whose depression is compounded with, say, substance abuse or a personality disorder may not get much help from SSRIs — which is unfortunate for the 45% to 60% of patients in the U.S. who have been diagnosed with a common mental disorder like depression and also meet the criteria for at least one other disorder, like substance abuse. (Multiple diagnoses are known in medical parlance as comorbidities.)

Which antidepressants are most effective?

The glut of antidepressant drugs on the market and the ads for them may have you – not to mention doctors – wondering how to tell one from the other. But a new study sheds light on which ones may be most effective in battling the blues.

Topping the list of a dozen prescription antidepressants reviewed: Zoloft and Lexapro. Patients taking those drugs in trials were also the least likely to drop out. But because Zoloft, made by New York-based Pfizer, is now off patent and available in relatively cheap, generic form, it may be the better choice for patients starting antidepressant therapy, write authors of the study published today in The Lancet, who are from Italy, Greece, England and Japan.

Anti-depressants' 'little effect'

New generation anti-depressants have little clinical benefit for most patients, research suggests.

A University of Hull team concluded the drugs actively help only a small group of the most severely depressed.

Marjorie Wallace, head of the mental health charity Sane, said that if these results were confirmed they could be "very disturbing".

But the makers of Prozac and Seroxat, two of the commonest anti-depressants, said they disagreed with the findings.

A spokesman for GlaxoSmithKline, which makes Seroxat, said the study only looked at a "small subset of the total data available".
