Is transcranial magnetic stimulation a new treatment of Bulimia Nervosa?

17.01.2008
A group of investigators of the Innsbruck University (Austria) reports on a new modality of treatment for bulimia nervosa, transcranial magnetic stimulation, in the 2008 January issue of Psychotherapy and Psychosomatics. Transcranial magnetic stimulation is a non-invasive, neurophysiological method, which affects cortical neurons with a short magnetic pulse.

Bulimia nervosa (BN) is often associated with depressive symptoms and treatment with antidepressants has shown positive effects. A shared deficient serotonergic transmission was postulated for both syndromes. The left dorsolateral prefrontal cortex was argued to regulate eating behaviour and to be dysfunctional in eating disorders.

Fourteen women meeting DSM-IV criteria for BN were included in a randomised placebo-controlled double-blind trial. In order to exclude patients highly responsive to placebo, all patients were first submitted to a one-week sham treatment. Randomisation was followed by 3 weeks of active treatment or sham stimulation. As the main outcome criterion we defined the change in binges and purges. Secondary outcome variables were the decrease of the Hamilton Depression Rating Scale (HDRS), the Beck Depression Inventory (BDI) and the Yale-Brown Obsessive Compulsive Scale (YBOCS) over time.

The average number of binges per day declined significantly between baseline and the end of treatment in the two groups. There was no significant difference between sham and active stimulation in terms of purge behaviour, BDI, HDRS and YBOCS over time.

These preliminary results indicate that repetitive transcranial magnetic stimulation (rTMS) in the treatment of BN does not exert additional benefit over placebo. A larger number of patients might clarify a further role of rTMS in the treatment of BN.

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Im Focus: Basel researchers succeed in cultivating cartilage from stem cells

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
