Psychomotor retardationPsychomotor retardation involves a slowing down of thought and a reduction of physical movements in an individual. It can cause a visible slowing of physical and emotional reactions, including speech and affect. Psychomotor retardation is most commonly seen in people with major depression and in the depressed phase of bipolar disorder; it is also associated with the adverse effects of certain drugs, such as benzodiazepines. Particularly in an inpatient setting, psychomotor retardation may require increased nursing care to ensure adequate food and fluid intake and sufficient personal care.
Psychotic depressionPsychotic depression, also known as depressive psychosis, is a major depressive episode that is accompanied by psychotic symptoms. It can occur in the context of bipolar disorder or major depressive disorder. It can be difficult to distinguish from schizoaffective disorder, a diagnosis that requires the presence of psychotic symptoms for at least two weeks without any mood symptoms present. Unipolar psychotic depression requires that psychotic symptoms occur during severe depressive episodes, although residual psychotic symptoms may also be present in between episodes (e.
Tic disorderTic disorders are defined in the Diagnostic and Statistical Manual of Mental Disorders (DSM) based on type (motor or phonic) and duration of tics (sudden, rapid, nonrhythmic movements). Tic disorders are defined similarly by the World Health Organization (ICD-10 codes). The fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published in May 2013, classifies Tourette syndrome and tic disorders as motor disorders listed in the neurodevelopmental disorder category.
History of mental disordersHistorically, mental disorders have had three major explanations, namely, the supernatural, biological and psychological models. For much of recorded history, deviant behavior has been considered supernatural and a reflection of the battle between good and evil. When confronted with unexplainable, irrational behavior and by suffering and upheaval, people have perceived evil. In fact, in the Persian Empire from 550 to 330 B.C., all physical and mental disorders were considered the work of the devil.
PsychoanalysisPsychoanalysis is a set of theories and therapeutic techniques that deal in part with the unconscious mind, and which together form a method of treatment for mental disorders. The discipline was established in the early 1890s by Sigmund Freud, whose work stemmed partly from the clinical work of Josef Breuer and others. Freud developed and refined the theory and practice of psychoanalysis until his death in 1939.
Individual psychologyIndividual psychology (Individualpsychologie) is a psychological method or science founded by the Viennese psychiatrist Alfred Adler. The English edition of Adler's work on the subject (1925) is a collection of papers and lectures given mainly between 1912 and 1914. The papers cover the whole range of human psychology in a single survey, and were intended to mirror the indivisible unity of the personality. In developing the concept of individual psychology, Adler broke away from the psychoanalytic school of Sigmund Freud.
Temporal lobe epilepsyIn the field of neurology, temporal lobe epilepsy is an enduring brain disorder that causes unprovoked seizures from the temporal lobe. Temporal lobe epilepsy is the most common type of focal onset epilepsy among adults. Seizure symptoms and behavior distinguish seizures arising from the medial temporal lobe from seizures arising from the lateral (neocortical) temporal lobe. Memory and psychiatric comorbidities may occur. Diagnosis relies on electroencephalographic (EEG) and neuroimaging studies.
RelapseIn internal medicine, relapse or recidivism is a recurrence of a past (typically medical) condition. For example, multiple sclerosis and malaria often exhibit peaks of activity and sometimes very long periods of dormancy, followed by relapse or recrudescence. In psychiatry, relapse or reinstatement of drug-seeking behavior, is the recurrence of pathological drug use, self harm or other symptoms after a period of recovery. Relapse is often observed in individuals who have developed a drug addiction or a form of drug dependence, as well as those who have a mental disorder.
NeurocognitionNeurocognitive 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 (i.e. at the cellular and molecular level). 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.
