Psychosurgery, also called neurosurgery for mental disorder (NMD), is the neurosurgical treatment of mental disorders. Psychosurgery has always been a controversial medical field. The modern history of psychosurgery begins in the 1880s under the Swiss psychiatrist Gottlieb Burckhardt. The first significant foray into psychosurgery in the 20th century was conducted by the Portuguese neurologist Egas Moniz who, during the mid-1930s, developed the operation known as leucotomy. The practice was enthusiastically taken up in the United States by the neuropsychiatrist Walter Freeman and the neurosurgeon James W. Watts who devised what became the standard prefrontal procedure and named their operative technique lobotomy, although the operation was called leucotomy in the United Kingdom. In spite of the award of the Nobel prize to Moniz in 1949, the use of psychosurgery declined during the 1950s. By the 1970s the standard Freeman-Watts type of operation was very rare, but other forms of psychosurgery, although used on a much smaller scale, survived. Some countries have abandoned psychosurgery altogether; in others, for example the US and the UK, it is only used in a few centres on small numbers of people with depression or obsessive-compulsive disorder (OCD). In some countries it is also used in the treatment of schizophrenia and other disorders.
Neuropsychology is a branch of psychology concerned with how a person's cognition and behavior are related to the brain and the rest of the nervous system. Professionals in this branch of psychology focus on how injuries or illnesses of the brain affect cognitive and behavioral functions.
Biological psychiatry or biopsychiatry is an approach to psychiatry that aims to understand mental disorder in terms of the biological function of the nervous system. It is interdisciplinary in its approach and draws on sciences such as neuroscience, psychopharmacology, biochemistry, genetics, epigenetics and physiology to investigate the biological bases of behavior and psychopathology. Biopsychiatry is the branch of medicine which deals with the study of the biological function of the nervous system in mental disorders.
The Institute of Psychiatry, Psychology & Neuroscience (IoPPN) is a leading centre for mental health and neuroscience research, education and training in Europe. It is dedicated to understanding, preventing and treating mental illness, neurological conditions, and other conditions that affect the brain. The IoPPN is a faculty of King's College London, England, and was previously known as the Institute of Psychiatry (IoP).
The Florey Institute of Neuroscience and Mental Health, more commonly known as The Florey, is an Australian medical research institute that undertakes research into treatments for brain and mind disorders. The institute's areas of interest include Parkinson's disease, stroke, motor neurone disease, addiction, epilepsy, multiple sclerosis, Autism, Huntington's disease, depression, schizophrenia, brain function in health and disease, heart failure, and dementia.
Professor Christos Pantelis is an Australian professor of medicine who is the Director of the Melbourne Neuropsychiatry Centre.
Neuropsychiatry is a branch of medicine that deals with psychiatry as it relates to neurology, in an effort to understand and attribute behavior to the interaction of neurobiology and social psychology factors. Within neuropsychiatry, the mind is considered "as an emergent property of the brain", whereas other behavioral and neurological specialties might consider the two as separate entities. Those disciplines are typically practiced separately.
Liaison psychiatry, also known as consultative psychiatry or consultation-liaison psychiatry, is the branch of psychiatry that specialises in the interface between general medicine/pediatrics and psychiatry, usually taking place in a hospital or medical setting. The role of the consultation-liaison psychiatrist is to see patients with comorbid medical conditions at the request of the treating medical or surgical consultant or team. Consultation-liaison psychiatry has areas of overlap with other disciplines including psychosomatic medicine, health psychology and neuropsychiatry.
Muriel Elaine Deutsch Lezak was an American neuropsychologist best known for her book Neuropsychological Assessment, widely accepted as the standard in the field. Her work has centred on the research, assessment, and rehabilitation of brain injury. Lezak was a professor of neurology at the Oregon Health and Science University School of Medicine.
Psychiatry is the medical specialty devoted to the diagnosis, prevention, and treatment of deleterious mental conditions. These include various matters related to mood, behaviour, cognition, perceptions, and emotions.
Forced Normalization (FN) is a psychiatric phenomenon in which a long term episodic epilepsy or migraine disorder is treated, and, although the electroencephalogram (EEG) appears to have stabilized, acute behavioral, mood, and psychological disturbances begin to manifest. If, or when, treatment for the disorder is halted, the disturbances go away, but the episodic spikes on the EEG reappear. H. Landolt coined the term 'Forced Normalization' in 1953 in response to a change he witnessed in epileptic EEGs, which monitor electrical activity in the brain. These changes were followed by abrupt behavioral changes in the patient. Landolt concluded that forced normalization is "the phenomenon characterized by the fact that, with the occurrence of psychotic states, the electroencephalography becomes more normal or entirely normal, as compared with previous and subsequent EEG findings." Forced normalization, as described by Landolt, was therefore an electrophysiological phenomenon with the electroencephalograph at its helm.
Perminder Sachdev is an Indian neuropsychiatrist based in Australia. He is a professor of neuropsychiatry at the University of New South Wales (UNSW), co-director of the UNSW Centre for Healthy Brain Aging, and clinical director of the Neuropsychiatric Institute at the Prince of Wales Hospital, Sydney. He is considered a trailblazer in the field of neuropsychiatry. Sachdev's research interests include ageing, vascular cognitive disorders such as vascular dementia, and psychiatric disorders.
Maxwell Richard Bennett is an Australian neuroscientist specializing in the function of synapses.
Professor Susan Rossell is a British researcher based at Swinburne University of Technology specialising in Neuropsychology and Neuroimaging. Originally from Nottingham, UK; she now resides in Melbourne, Australia. Her research on the neuropsychology of schizophrenia and body dysmorphic disorder is internationally recognised.
Elizabeth Scarr is an Australian scientist. Her research investigates the chemical changes in the brain associated schizophrenia and bipolar disorder.
Dr. Brigitte Kieffer is a French molecular neurobiologist known for her research of opiate receptors. Her areas of expertise include: molecular psychiatry, addiction, mood disorders, pain, and developmental disorders. Kieffer has international reputation in the field of opiate receptors, and has paved the way for better understanding of brain mechanisms involved in pain, mental illness, and drug addiction. She continues to pursue research and directs a team of over 300 people. Her discoveries have shed light on how substances like morphine or heroin can kill pain, and foster addiction.

He is Scientia Professor of Psychology at the University of New South Wales (UNSW) and director of the UNSW Traumatic Stress Clinic, based at UNSW and Westmead Institute for Medical Research. His main areas of research are posttraumatic stress disorder (PTSD) and prolonged grief disorder. On 13 June 2016 he was appointed a Companion of the Order of Australia (AC), for eminent service to medical research in the field of psychotraumatology, as a psychologist and author, to the study of Indigenous mental health, as an advisor to a range of government and international organisations, and to professional societies.
F. Markus Leweke is a German psychiatrist and psychotherapist. He is a professor and Chair in Youth Depression Studies at the Brain and Mind Centre of the University of Sydney, Australia and a work group leader at the Central Institute of Mental Health in Mannheim, Germany.
The Queensland Brain Institute (QBI) is an Australian neuroscience research institute, located in Brisbane at the St Lucia campus of The University of Queensland (UQ). Founding director Professor Perry Bartlett established the QBI in 2003 with assistance from The University of Queensland, Queensland State Government, and Chuck Feeney, founder of The Atlantic Philanthropies. The purpose-built facility was commissioned in 2004 and on 19 November 2007, the building was opened by former Queensland Premier Anna Bligh.
