MDD is a common, debilitating disease prevalent in childhood and adolescence. Examination of cortical thickness in patients with MDD has not been widely studied, and WSU's team of researchers set out to determine if differences in cortical thickness might not only distinguish children with depression from healthy children who are not depressed but also from those with other psychiatric disorders such as OCD.
Using a new technique to measure cortical thickness of 24 MDD patients, 24 OCD patients and 30 healthy control patients, the research team led by David Rosenberg, M.D., the Miriam L. Hamburger Endowed Chair of Child Psychiatry and professor of psychiatry and behavioral neurosciences in the School of Medicine at Wayne State University, and Erin Fallucca, M.D., a psychiatry resident at Wayne State University and the Detroit Medical Center, observed cortical thinning in five regions of the brain and greater thickness in the bilateral temporal pole in MDD patients. In OCD patients, the only significantly different region from healthy control patients was a thinner left supramarginal gyrus.
"The findings from our study are very exciting," said Rosenberg. "By measuring cortical thickness, we were able to distinguish depressed children not only from healthy children without depression, but also from those with another psychiatric disorder, obsessive compulsive disorder."
The study also revealed that familial depressed patients, or children with at least one first-degree relative with depression, had distinct cortical thickness compared to children with no obvious family history of mood disorder.
"Depressed children with and without a family history of depression who met the same clinical criteria of depression and who appeared the same clinically, had completely different cortical thickness based on their family history of depression," said Rosenberg.
This study offers an exciting new way to identify more objective markers of psychiatric illness in children. "It may have potential treatment significance for one-third of depressed children who do not respond to any treatment, and also for many who only partially respond with continued functional impairment," said Rosenberg. "We have found a clue to guide us to look at subtypes of depression just as we would in other chronic medical illnesses like diabetes, such as insulin dependent and non-insulin dependent diabetes."

Young Sr. Psychiatric Research and Training Program, the World Heritage Foundation, the Schutt Foundation, the United Way, the National Alliance for Research on Schizophrenia and Depression and the Mental Illness Research Association.

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
