Andreas Müller

Andreas Müller


Andreas is an expert in the study of the human brain. For the past 17 years he has been the CEO of the Bündner Brain and Trauma Foundation has been exploring the links between biology and mental disorders – for example in ADHD. Previously the head of the School Psychology Service Graubünden together with the world-famous Russian neurophysiologist Yuri Kropotov, in 2003 he initiated his first research project: recordings of brainwaves of 250 healthy children and adolescents to create a database. As early as 2004, the database was expanded by 540 adults. Together with people from Norway and Russia, the people of Grisons formed the basis of an index database on the human brain. Müller has been CEO of the Brain and Trauma Foundation in Grisons since 2006.

Comparatively new to Müller’s research is that mental illness can be objectively detected by quantitative comparisons of measurements with the so-called EEG. Müller likes to make use of a comparison from another area of ​​medicine: “Psychiatry is today at the point where surgery in the invention of the X-ray apparatus was more than 100 years ago.” Muller and his colleagues have studied the biological causes of Attention-Deficit / Hyperactivity Disorder (ADHD) with particular interest. According to Müller, this research focus has come from everyday practice as a child and adolescent psychologist. “Our research must benefit patients exclusively.” ADHD visible in black on white, Muller has since lectured internationally on this topic in South Korea, United States, Israel, Brazil and more. For the method, among other things, the patients have to analyze images on the PC for 22 minutes and click on the correct sequence with a computer mouse. “Persons affected by ADHD are very hard-eyed anyway,” says Müller. Because the brain waves were measured during the test, the researchers could also objectively detect the disorder – black and white. The method enables a virtually unequivocal diagnosis of ADHD, says Müller. “Thanks to the measurements, we also know what we need to do in therapy.” In addition to detailed instructions for the procedure in non-drug therapies, he mentions the great advantages of prescribing drugs such as Ritalin. “In conventional diagnoses, around two-thirds of patients respond to the medication. The method provides virtually 100% responder quality. This same method has been expanded to understanding chronic pain, anxiety, Parkinson’s disease, and more.
