Pr Pierre Flor-Henry

Professeur de psychiatrie clinique, Directeur de la Clinique de psychiatrie adulte et Directeur des Diagnostics cliniques et du Centre de recherches  de l’Hôpital Alberta à Edmonton – Canada.

In 1993 Flor-Henry undertook the Directorship of the Clinical Diagnostics and Research Centre (CDRC), Alberta Hospital Edmonton. All four positions have been held concurrently through present day. Much of Pierre Flor-Henry’s clinical and research is conducted in the CDRC which he established and directs. The CDRC is dedicated to offering clinical psychophysiological and neurophysiological assessments that contribute to the diagnosis and treatment of patients. The philosophy of the CDRC is to provide continuous improvement in the provision of assessment and treatment services through fundamental research and program evaluation. The CDRC provides a variety of tests of brain activity that is unique to a psychiatric facility in its breadth and scope. Assessments include clinical EEG recordings, electrocardiograms, multi-channel EEG brain mapping as well as auditory, somatosensory, and cognitive evoked potential recordings. Other assessments include recordings of autonomic nervous system modalities such as skin conductance and digital pulse volume. Basic research is conducted in the analysis of brain electrical activity in order to improve the understanding of abnormal cerebral mechanisms associated with mental illness and to improve the quality of assessment and treatment. The Alberta College of Physicians and Surgeons in Canada awarded the Clinical Diagnostics and Research Centre full accreditation status as an electroencephalography and evoked potential neurophysiology laboratory. In recent years, Flor-Henry has engaged in multi-channel EEG investigations using source localization (LORETA) in a variety of psychiatric disorders: schizophrenia, mania, depression, multiple personality, chronic fatigue, fibromyalgia… Also, he has investigated in a similar way, differences in EEG organization of normal males and females, of cerebral activity during verbal and spatial cognitive tasks, and of male/female difference in the psychoses. In addition to his extensive empirical research, he has written, edited, and published a number of books integrating the findings in these areas along with theoretical reviews on the implications of disrupted lateral hemispheric organization in psychiatric conditions.In 2007, Dr. Flor-Henry was named the 2007 recipient for the Career Contribution Award from the EEG and Clinical Neuroscience Society. This award was given in recognition of his lifetime contributions to clinical neurophysiology in psychiatry.

« My most important initial contribution to research was the demonstration in the study of epileptic psychosis that schizophrenia relates to left and manic-depressive states to right hemisphere epilepsies (1969). This was the first time that schizophrenia was related to dominant fronto-temporal dysfunction. The publication of these findings has triggered an enormous amount of research, internationally, in the last thirty years on laterality and psychopathology. My own research has extended these early findings to the study of the patterns of cerebral disorganization in a variety of mental disorders with neuropsychological and quantitative EEG approaches: i.e., in depression and psychopathy; in schizophrenia, mania and depression; in sexual deviations; in hysteria and multiple personality; in obsessive compulsive disorder; in normal controls task, age, gender effects. I have written and edited a number of books integrating the findings in this area. I have published a number of theoretical reviews on the implications of disrupted lateral hemispheric organization. In recent years my research has been focussed on multi-channel statistical EEG cartography, source localization and electrodermal psychophysiology in the study of male/female differences and resting, verbal and spatial cognitive states in normals and in psychopathological states. »
