Summary: Treatments for melancholy together with ECT and antidepressants improve mind connectivity in these with medical melancholy.

Scientists consider that the construction of the grownup mind is mostly inflexible and incapable of fast modifications; now new work has proven that this isn’t true.
German researchers have proven that in-patient therapy for melancholy can result in a rise in mind connectivity, and people sufferers who reply properly to this therapy present a better improve in connectivity than those that don’t.
Presenting the work on the European College for Neuropsychopharmacology Congress in Vienna, lead researcher, Professor Jonathan Repple mentioned:
Commenting, Dr Eric Ruhe, Rabdoud University Medical Center, Nijmegen, the Netherlands mentioned:
“This means that the brain structure of patients with serious clinical depression is not as fixed as we thought, and we can improve brain structure within a short time frame, around 6 weeks.
“We found that if this treatment leads to an increase in brain connectivity, it is also effective in tackling depression symptoms. This gives hope to patients who believe nothing can change and they have to live with a disease forever, because it is “set in stone” of their mind”.
The researchers, working on the University of Muenster in Germany, studied 109 sufferers with severe melancholy (Major Depressive Disorder) and in contrast them with 55 wholesome controls. Their brains have been scanned utilizing an MRI scanner which had been set as much as establish which components of the mind have been speaking with different components, figuring out the extent of connections throughout the mind.
The sufferers have been then handled for melancholy, some with electroconvulsive remedy (ECT), some with psychological remedy or remedy, some with a mixture of all therapies. After therapy they have been then rescanned and the variety of connections recounted. They have been additionally retested for signs of melancholy.
Professor Repple (now Professor of Predictive Psychiatry on the University of Frankfurt) mentioned:
“We found that treatment for depression changed the infrastructure of the brain, which goes against previous expectations. Treated patients showed a greater number of connections than they had shown before treatment.
“Moreover, those who showed the most response to treatment had developed a greater the number of new connections than those who showed little response.
“A second scan showing that there are no time effects in healthy controls supports our findings that we see something that is related to the disease and more importantly the treatment of this disease.
We found these changes took place over a period of only around 6 weeks, we were surprised at the speed of response. We don’t have an explanation as to how these changes take place, or why they should happen with such different forms of treatment”.
“This is a very interesting and difficult to perform study in which the authors repeated MRI-scans to reveal changes in structural connectivity over time in patients treated for depression.
The results align very much with our current belief that the brain has much more flexibility in adaptation over (even short) time than was previously thought. Indeed a major idea of what treatment of depression (and other psychiatric illnesses) invoke is plastic changes over time. This has been proposed as a common mechanism for antidepressants, psychotherapy and electroconvulsive therapy.

However, the amount of research to elucidate what changes are necessary or specific for response to treatment or remission of the depression is limited.
Moreover, the next question is whether different treatments have the possibility to specifically change targeted brain networks or vice versa whether we can use the disturbances in brain-networks as measured in the present study to choose which therapy will be helpful.
The fact that the observed changes over time could not be associated with a form of treatment is a pity, but as the authors themselves suggest a topic for further research.
“First these results should be replicated in independent samples which hopefully is going to happen soon.
“Second further elaboration on this approach would be daunting and should be supported firmly as this work might help to bridge the current gap between neuroscience and evidence based patient care”.
This is an impartial remark, Dr Ruhe was not concerned on this examine.
