Neurology is the branch of medicine dealing with the diagnosis and treatment of all categories of conditions and disease involving the nervous system, which comprises the brain, the spinal cord and the peripheral nerves. Neurological practice relies heavily on the field of neuroscience, the scientific study of the nervous system.
Neurocognitive functions are cognitive functions closely linked to the function of particular areas, neural pathways, or cortical networks in the brain, ultimately served by the substrate of the brain's neurological matrix. Therefore, their understanding is closely linked to the practice of neuropsychology and cognitive neuroscience – two disciplines that broadly seek to understand how the structure and function of the brain relate to cognition and behaviour.
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.
Cognitive neuropsychology is a branch of cognitive psychology that aims to understand how the structure and function of the brain relates to specific psychological processes. Cognitive psychology is the science that looks at how mental processes are responsible for the cognitive abilities to store and produce new memories, produce language, recognize people and objects, as well as our ability to reason and problem solve. Cognitive neuropsychology places a particular emphasis on studying the cognitive effects of brain injury or neurological illness with a view to inferring models of normal cognitive functioning. Evidence is based on case studies of individual brain damaged patients who show deficits in brain areas and from patients who exhibit double dissociations. Double dissociations involve two patients and two tasks. One patient is impaired at one task but normal on the other, while the other patient is normal on the first task and impaired on the other. For example, patient A would be poor at reading printed words while still being normal at understanding spoken words, while the patient B would be normal at understanding written words and be poor at understanding spoken words. Scientists can interpret this information to explain how there is a single cognitive module for word comprehension. From studies like these, researchers infer that different areas of the brain are highly specialised. Cognitive neuropsychology can be distinguished from cognitive neuroscience, which is also interested in brain-damaged patients, but is particularly focused on uncovering the neural mechanisms underlying cognitive processes.
The attempts to derive the links between the damage to specific brain areas and problems in behaviour are known throughout the history for 3 millennia. However, the first systematic neuropsychological assessment and a battery of the behavioural tasks to investigate specific aspects of behavioural regulation was developed by Alexander Luria in 1942-1948. Luria was working with big samples of brain-injured Russian soldiers during and after the second World War. Among many insights from Luria's rehabilitation practice and observations, was the fundamental discovery of the involvement of frontal lobes of the cortex in plasticity, initiation, planning and organization of behaviour. His Go/no-go task, which was one of the tasks screening for the frontal lobe damage, "count by 7", hands-clutching, clock-drawing task, drawing of repeatitive patterns, word associations and categories recall and others became standard components of neuropsychological assessment and mental status screening. Considering the originality and multiplicity of neuropsychological components offered by Alexander Luria, he is recognized as a father of neuropsychological assessment. Alexander Luria's neuropsychological battery was adapted in the United States in the form of Luria-Nebraska neuropsychological battery in 1970s. Then the tasks used in this battery were borrowed in more modern neuropsychological batteries and in the Mini–mental state examination test for screening of demenia.
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 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).
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.
Autoscopy is the experience in which an individual perceives the surrounding environment from a different perspective, from a position outside of their own body. Autoscopy comes from the ancient Greek autós and skopós.
A neurological disorder is any disorder of the nervous system. Structural, biochemical or electrical abnormalities in the brain, spinal cord or other nerves can result in a range of symptoms. Examples of symptoms include paralysis, muscle weakness, poor coordination, loss of sensation, seizures, confusion, pain, tauopathies, and altered levels of consciousness. There are many recognized neurological disorders, some are relatively common, but many are rare.
Pediatric neuropsychology is a sub-speciality within the field of clinical neuropsychology that studies the relationship between brain health and behaviour in children. Many pediatric neuropsychologists are involved in teaching, research, supervision, and training of undergraduate and graduate students in the field.
Some of the research that is conducted in the field of psychology is more "fundamental" than the research conducted in the applied psychological disciplines, and does not necessarily have a direct application. The subdisciplines within psychology that can be thought to reflect a basic-science orientation include biological psychology, cognitive psychology, neuropsychology, and so on. Research in these subdisciplines is characterized by methodological rigor. The concern of psychology as a basic science is in understanding the laws and processes that underlie behavior, cognition, and emotion. Psychology as a basic science provides a foundation for applied psychology. Applied psychology, by contrast, involves the application of psychological principles and theories yielded up by the basic psychological sciences; these applications are aimed at overcoming problems or promoting well-being in areas such as mental and physical health and education.
Alice Medalia is an American clinical neuropsychologist and international leader in the field of psychiatric rehabilitation. She is best known for her work treating cognitive deficits in people with psychiatric disorders. This subspecialty is known as cognitive remediation.
Psychology encompasses a vast domain, and includes many different approaches to the study of mental processes and behavior. Below are the major areas of inquiry that taken together constitute psychology. A comprehensive list of the sub-fields and areas within psychology can be found at the list of psychology topics and list of psychology disciplines.
The following outline is provided as an overview of and topical guide to psychiatry:
The American Neuropsychiatric Association (ANPA) is a non-profit organization of professionals in neuropsychiatry, behavioral neurology and the clinical neurosciences, with over 700 members from around the world. Established in 1988, its mission is to improve the lives of people with disorders at the interface of psychiatry and neurology, with the vision of transforming recognition, understanding and treatment of neuropsychiatric disorders. It founded in 1988 by two academic physicians doubly certified in neurology and psychiatry, Barry S. Fogel and Randolph Schiffer.
