Tim Crow
Timothy John Crow, (7 June 1938 – 10 November 2024) was a British psychiatrist and researcher. Much of his research was related to finding the causes of schizophrenia. He also had an interest in neurology and evolutionary theory. He was the Honorary Director of the Prince of Wales International Centre for Research into Schizophrenia and Depression. He qualified at the Royal London Hospital in 1964 and obtained a PhD at the University of Aberdeen, Scotland in 1970. He was a Fellow of the Royal College of Physicians, the Royal College of Psychiatrists and the Academy of Medical Sciences. Crow was, for twenty years, Head of the Division of Psychiatry of the Medical Research Council (MRC) Clinical Research Centre at Northwick Park Hospital and then a member of the External Scientific Staff of the MRC in Oxford. Research Neurobiology of reinforcement and motivation Crow worked in the Department of Physiology at the University of Aberdeen in the late 1960s and early 1970s, ...

CREDENTIAL
A credential is a piece of any document that details a qualification, competence, or authority issued to an individual by a third party with a relevant or ''de facto'' authority or assumed competence to do so. Examples of credentials include academic diplomas, academic degrees, Professional certification, certifications, security clearances, Identity document, identification documents, badges, passwords, user names, key (lock), keys, power of attorney, powers of attorney, and so on. Sometimes publications, such as scientific papers or books, may be viewed as similar to credentials by some people, especially if the publication was peer reviewed or made in a well-known Academic journal, journal or reputable publisher. Types and documentation of credentials A person holding a credential is usually given documentation or secret knowledge (''e.g.,'' a password or key) as proof of the credential. Sometimes this proof (or a copy of it) is held by a third, trusted party. While in some c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northwick Park Hospital
Northwick Park Hospital (NWPH) is a major National Health Service hospital situated in the town of Harrow, North West London, managed by the London North West University Healthcare NHS Trust. It is located off Watford Road in the London Borough of Brent; closely bordering the London Borough of Harrow. History The hospital was commissioned by the North West Metropolitan Regional Hospital Board in the late 1960s, designed by the British architect John Weeks and built by Trollope & Colls. The design of the hospital was largely inspired by British obsolescence studies, in which a loose-jointed medical complex was created with flexibility to withstand obsolescence's unpredictable effects. With only a fixed internal street system, the architects referred to the hospital as "an indeterminate architecture" with "no final plan" – free to grow and change over time. It was opened by the Queen on 10 October 1970. It takes its name from Northwick Park, which lies besides the hospital. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MRI Scans
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from computed tomography (CT) and positron emission tomography (PET) scans. MRI is a medical application of nuclear magnetic resonance (NMR) which can also be used for imaging in other NMR applications, such as NMR spectroscopy. MRI is widely used in hospitals and clinics for medical diagnosis, staging and follow-up of disease. Compared to CT, MRI provides better contrast in images of soft tissues, e.g. in the brain or abdomen. However, it may be perceived as less comfortable by patients, due to the usually longer and louder measurements with the subject in a long, confining tube, although "open" MR ...

Cerebral Ventricles
In neuroanatomy, the ventricular system is a set of four interconnected cavities known as cerebral ventricles in the brain. Within each ventricle is a region of choroid plexus which produces the circulating cerebrospinal fluid (CSF). The ventricular system is continuous with the central canal of the spinal cord from the fourth ventricle, allowing for the flow of CSF to circulate. All of the ventricular system and the central canal of the spinal cord are lined with ependyma, a specialised form of epithelium connected by tight junctions that make up the blood–cerebrospinal fluid barrier. Structure The system comprises four ventricles: * lateral ventricles right and left (one for each hemisphere) * third ventricle * fourth ventricle There are several foramina, openings acting as channels, that connect the ventricles. The interventricular foramina (also called the foramina of Monro) connect the lateral ventricles to the third ventricle through which the cerebrospinal fluid ca ...

CT Scan
A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists. CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry (medical), gantry to measure X-ray Attenuation#Radiography, attenuations by different tissues inside the body. The multiple X-ray measurements taken from different angles are then processed on a computer using tomographic reconstruction algorithms to produce Tomography, tomographic (cross-sectional) images (virtual "slices") of a body. CT scans can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is Contraindication, contraindicated. Since its development in the 1970s, CT scanning has proven to be a versatile imaging technique. While CT is most prominently used in medical diagnosis, i ...

Manic-depressive
Bipolar disorder (BD), previously known as manic depression, is a mental disorder characterized by periods of depression and periods of abnormally elevated mood that each last from days to weeks, and in some cases months. If the elevated mood is severe or associated with psychosis, it is called ''mania''; if it is less severe and does not significantly affect functioning, it is called ''hypomania''. During mania, an individual behaves or feels abnormally energetic, happy, or irritable, and they often make impulsive decisions with little regard for the consequences. There is usually, but not always, a reduced need for sleep during manic phases. During periods of depression, the individual may experience crying, have a negative outlook on life, and demonstrate poor eye contact with others. The risk of suicide is high. Over a period of 20 years, 6% of those with bipolar disorder died by suicide, with about one-third attempting suicide in their lifetime. Among those with the d ...

Thought Disorder
A thought disorder (TD) is a disturbance in cognition which affects language, thought and communication. Psychiatric and psychological glossaries in 2015 and 2017 identified thought disorders as encompassing poverty of ideas, paralogia (a reasoning disorder characterized by expression of illogical or delusional thoughts), word salad, and delusions—all disturbances of thought content and form. Two specific terms have been suggested—content thought disorder (CTD) and formal thought disorder (FTD). CTD has been defined as a thought disturbance characterized by multiple fragmented delusions, and the term ''thought disorder'' is often used to refer to an FTD: a disruption of the form (or structure) of thought. Also known as disorganized thinking, FTD results in disorganized speech and is recognized as a major feature of schizophrenia and other psychoses (including mood disorders, dementia, mania, and neurological diseases). Disorganized speech leads to an inference of disorgani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hallucinations
A hallucination is a perception in the absence of an external stimulus that has the compelling sense of reality. They are distinguishable from several related phenomena, such as dreaming ( REM sleep), which does not involve wakefulness; pseudohallucination, which does not mimic real perception, and is accurately perceived as unreal; illusion, which involves distorted or misinterpreted real perception; and mental imagery, which does not mimic real perception, and is under voluntary control. Hallucinations also differ from " delusional perceptions", in which a correctly sensed and interpreted stimulus (i.e., a real perception) is given some additional significance. Hallucinations can occur in any sensory modality— visual, auditory, olfactory, gustatory, tactile, proprioceptive, equilibrioceptive, nociceptive, thermoceptive and chronoceptive. Hallucinations are referred to as multimodal if multiple sensory modalities occur. A mild form of hallucination is known as ...

Delusions
A delusion is a fixed belief that is not amenable to change in light of conflicting evidence. As a pathology, it is distinct from a belief based on false or incomplete information, confabulation, dogma, illusion, hallucination, or some other misleading effects of perception, as individuals with those beliefs ''are'' able to change or readjust their beliefs upon reviewing the evidence. However: "The distinction between a delusion and a strongly held idea is sometimes difficult to make and depends in part on the degree of conviction with which the belief is held despite clear or reasonable contradictory evidence regarding its veracity." Delusions have been found to occur in the context of many pathological states (both general physical and mental) and are of particular diagnostic importance in psychosis, psychotic disorders including schizophrenia, paraphrenia, Mania, manic episodes of bipolar disorder, and psychotic depression. Types Delusions are categorized into four differe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychoses
In psychopathology, psychosis is a condition in which a person is unable to distinguish, in their experience of life, between what is and is not real. Examples of psychotic symptoms are delusions, hallucinations, and disorganized or incoherent thoughts or speech. Psychosis is a description of a person's state or symptoms, rather than a particular mental illness, and it is not related to psychopathy (a personality construct characterized by impaired empathy and remorse, along with bold, disinhibited, and egocentric traits). Common causes of chronic (i.e. ongoing or repeating) psychosis include schizophrenia or schizoaffective disorder, bipolar disorder, and brain damage (usually as a result of alcoholism). Acute (temporary) psychosis can also be caused by severe distress, sleep deprivation, sensory deprivation, some medications, and drug use (including alcohol, cannabis, hallucinogens, and stimulants). Acute psychosis is termed primary if it results from a psychiatri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endogenous Depression
Endogenous depression is an atypical subclass of major depressive disorder (clinical depression). It could be caused by genetic and biological factors. Endogenous depression occurs due to the presence of an internal (cognitive, biological) stressor instead of an external (social, environmental) stressor. Endogenous depression includes patients with treatment-resistant, non-psychotic, major depressive disorder, characterized by abnormal behavior of the endogenous opioid system but not the monoaminergic system. Symptoms vary in severity, type, and frequency and can be attributed to cognitive, social, biological, or environmental factors that result in persistent feelings of sadness and distress. Since symptoms are due to a biological phenomenon, prevalence rates tend to be higher in older adults. Due to this fact, biological-focused treatment plans are often used in therapy to ensure the best prognosis. Endogenous depression was part of the Kraepelinian dichotomy system. Signs an ...

Electroconvulsive Therapy
Electroconvulsive therapy (ECT) is a psychiatry, psychiatric treatment that causes a generalized seizure by passing electrical current through the brain. ECT is often used as an intervention for mental disorders when other treatments are inadequate. Conditions responsive to ECT include major depressive disorder, mania, and catatonia.FDAFDA Executive Summary Prepared for the January 27–28, 2011 meeting of the Neurological Devices Panel Meeting to Discuss the Classification of Electroconvulsive Therapy Devices (ECT). Quote, p. 38: "Three major practice guidelines have been published on ECT. These guidelines include: APA Task Force on ECT (2001); Third report of the Royal College of Psychiatrists' Special Committee on ECT (2004); National Institute for Health and Clinical Excellence (NICE 2003; NICE 2009). There is significant agreement between the three sets of recommendations." The general physical risks of ECT are similar to those of brief general anesthesia. Immediately fol ...
