Genetic Testing for Depression Drugs

Peter ForsterCosts of Treatment, Major Depression, Testing, Treatments of Depression

Genetic testing for depression drugs is a new approach to selecting medications that may have value, especially in patients with treatment resistant depression. We have been using the Genecept Assay for patients with treatment resistant depression and have found that the results improve our ability to choose effective treatments. Patients who have failed multiple adequate trials of medications are much less likely to …

TMS Mechanism of Action – Changes in Brain Connectivity?

Peter ForsterBasic Science, Treatments of Depression

TMS’s mechanism of action has been unclear. Transcranial magnetic stimulation affects activity locally in the region of the brain that is stimulated, but does that explain how it works? Since it affects local activity in every patient, why does it not work for everyone? A new article in Biological Psychiatry suggests that it may be changes in brain connectivity that …

Exercise and Stress – How Exercise Prevents Depression

Peter ForsterMajor Depression, Physical Conditions and Health, Treatments of Depression

Exercise seems to reduce stress. But how does this work? And what about exercise effects on depression? An article in the New York Times summarizes a recent publication in the journal Cell which may explain how exercise prevents depression. A wealth of research shows that regular exercise reduces the risk of depression. A very large study in Britain, for example, suggested that …

TMS Outcomes – Long Term Study

Peter ForsterMajor Depression, Treatments of Depression

TMS outcomes have seemed favorable for patients with treatment resistant major depression, but what are the long term effects of TMS (transcranial magnetic stimulation)? TMS is a non-invasive technique for stimulating brain activity in parts of the brain that seem to be turned off in depression – the dorsolateral prefrontal cortex. TMS uses magnets to stimulate the brain and the …

Blood Test for Depression

Peter ForsterBasic Science, Diagnosis, Major Depression, Psychobiology, Testing, Treatments of Depression

How many times has a new patient in the clinic asked, “isn’t there a blood test for depression?” Always in the past we had to say that there were no reliable tests that could identify depression. There was some evidence that functional brain imaging could do so but the technique was expensive and experimental. In an article published in the …

Cortisol and Depression

Peter ForsterPsychobiology

A middle aged man with depression came in today for his first psychiatric evaluation. He had lots of questions about the relationship between cortisol and depression, because his first serious depression, at age 45, occurred in the context of a severe work stress. And this work stress was associated with many physical manifestations of stress – fatigue, severely disrupted sleep, …

Huge Victory on Mental Health Parity in California

Peter ForsterCosts of Treatment, Policy

On September 10th the California Supreme Court let stand a California Appeals Court decision that the California mental health parity law requires coverage of treatment that may have no equivalent in other medical specialties. Specifically, the Appeals Court held that Blue Shield of California must cover residential treatment for eating disorders. The Court noted that residential treatment was among the …

Genetic Testing Guides Treatment for Bipolar or Depression

Peter ForsterDiagnosis, Testing

We have been using a relatively new assay from a company called Genomind (the Genecept test) in some of our patients with bipolar and/or depression. The test involves a saliva sample which is analyzed for ten gene variants that may be useful in guiding treatment. So far we find that in about half of the patients with treatment resistant depression …

Treatment of Fatigue in Patients with Depression or Bipolar

Peter ForsterBipolar Treatment, Diagnosis, Physical Conditions and Health, Treatments of Depression

Treatment of depression in patients with depression or bipolar is often complicated. If medications are prescribed, will they make mood symptoms worse, or have other significant adverse effects? And yet fatigue is common in people with a history of depression (it occurs in up to 10% of the general population and is much more common in women, who have a …

Low Frequency Magnetic Stimulation is Rapid Antidepressant

Peter ForsterBipolar Treatment, Treatments of Depression

There is a lot of interest in an article that just appeared in Biological Psychiatry about a new magnetic stimulation technique that may be associated with rapid antidepressant effects in both unipolar and bipolar depression. Researchers at McLean Hospital were studying Low Frequency Magnetic Stimulation as a way of imaging the brains of bipolar patients and discovered that many of …
