Antidepressant drugs can get depression better, but cannot keep well

21.12.2006
In a paper published in the current issue of Expert Review of Neurotherapeutics, Giovanni A. Fava, Seung Park and Nicoletta Sonino (University of Bologna and SUNYAB at Buffalo) examine the evidence on the role of antidepressant drugs in preventing a depressive relapse. The news is rather depressing. But the role of psychotherapy much more encouraging.

Approximately 8 of 10 people experiencing a major depressive episode will have one or more further episodes during their lifetime, a recurrent major depressive disorder. Prolongation or lifelong pharmacotherapy has emerged as the main therapeutic tool for preventing relapse in depression. However, outcome after discontinuation of antidepressants does not seem to be affected by the duration of their administration. Loss of clinical effects, despite adequate compliance, has also emerged as a vexing clinical problem.

Use of intermittent pharmacotherapy with follow-up visits is another therapeutic option that would leave patients with periods free of drugs and side effects, in consideration of the fact that a high proportion of patients would discontinue the antidepressant anyway. However, the problems of resistance (the fact that a drug treatment may be associated with a diminished chance of response in those patients who successfully responded to it, but discontinued it) and of discontinuation syndromes are a substantial disadvantage of this therapeutic option.

In recent years, several controlled trials have suggested that a sequential use of pharmacotherapy in the treatment of the acute episode and psychotherapy in its residual phase may improve long-term outcome. Patients, however, should be motivated for psychotherapy and skilled therapists should be available.

It is important to discuss with the patient the various therapeutic options and to adapt strategies to the specific needs of patients.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
