Biography

Kahn studied medicine from 1972 to 1979 at the University of Groningen, and then specialized in psychiatry and neurology at the University of Utrecht and the Academic Medical Center, respectively. He is a registered neuropsychiatrist since 1986. In 1990 he obtained his Ph.D. with professors Herman van Praag and David de Wied as mentors at the University of Utrecht on the thesis Serotonin Receptor Hypersensitivity in Panic Disorder: an Hypothesis.^{[7] [8]}

Kahn served in the Royal Netherlands Army as a first lieutenant in 1980 and 1981.^[9]

Following residencies in the Netherlands, he attended the Albert Einstein College of Medicine in New York City for a research fellowship in biological psychiatry. From there he completed psychiatry residencies at Mount Sinai Hospital and then acted as the chief of the psychiatry research unit at the Bronx VA Hospital.^[10] In 1993 he returned to the Netherlands be the chair of psychiatry at the University Medical Center. He led the Brain Center Rudolf Magnus^[11] —a multi-discipline center for research in fundamental neuroscience, psychiatry, neurology, neurosurgery and rehabilitation medicine—for over 10 years, until 2017.

Research

Kahn studies biological causes of psychiatric disorders such as schizophrenia and has led numerous consortia examining the brain changes that play a role in schizophrenia. He has coordinated several international trials to optimize the treatment of schizophrenia.

He is known for helping establish proof that schizophrenia debuts with cognitive dysfunction, preceding the onset of the first incidence of psychosis by more than a decade. He and associates further showed that brain volume is one of the most heritable characteristics, paving the way to link brain volumes in health and disease to genetic variation.^{[15] [16]}

Grants and trials

As of 2020, Kahn is the principal investigator or co-principal investigator on 13 active grants related to child development and drug augmentation for onset schizophrenia to prevent psychosis and cognitive therapy symptoms.^[17]
