New hope for schizophrenia sufferers

08.08.2005


Key research from the University of New South Wales (UNSW) could lead to the first early diagnostic tool for schizophrenia and bipolar disorder.



"At the moment we don’t have any biological tests for these conditions," said one of the authors, UNSW Associate Professor of Psychiatry, Philip Ward, who is based at Liverpool Hospital’s Schizophrenia Research Unit. "Our research could eventually lead to a simple, cost-effective and safe way to distinguish patients with schizophrenia from those suffering bipolar disorder. This is important because a patient can get treatment sooner and hopefully have a better outcome."

Auditory recovery cycle dysfunction in schizophrenia: A study using event-related potentials has just been published in the international journal Psychiatry Research.


"Sixty percent of patients with schizophrenia have auditory hallucinations," said co-author, UNSW PhD candidate Nathan Clunas. "So we decided to look at a particular brain wave-form which measures attention and attention deficits that can be found in these patients."

The researchers recorded the brain waves associated with pairs of sounds in 17 patients with schizophrenia. Subjects heard the sounds through a set of headphones, while performing a visual distraction task. The patients’ results were compared with those of a sex and age-matched healthy volunteer group.

"We were looking at what occurs about 100 milliseconds after the sounds were presented," said Nathan Clunas. "The distinctive pattern observed in healthy volunteers was disrupted in patients with schizophrenia.

"These findings may help us understand the problems patients with schizophrenia experience in focussing attention on everyday events," said Nathan Clunas.

The researchers are currently analysing the results of patients with bipolar disorder, to see whether different patterns of response to sounds are seen in these patients.

"Depending on the final results in the bipolar group, we may be on the way to developing a biological test," said Professor Ward.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
