Sleep Walk
Sleepwalking, also known as somnambulism or noctambulism, is a phenomenon of combined sleep and wakefulness. It is classified as a sleep disorder belonging to the parasomnia family. It occurs during slow wave stage of sleep, in a state of low consciousness, with performance of activities that are usually performed during a state of full consciousness. These activities can be as benign as talking, sitting up in bed, walking to a bathroom, consuming food, and cleaning, or as hazardous as cooking, driving a motor vehicle, violent gestures and grabbing at hallucinated objects.Swanson, Jenifer, ed. "Sleepwalking". ''Sleep Disorders Sourcebook''. MI: Omnigraphics, 1999. 249–254, 351–352. Although sleepwalking cases generally consist of simple, repeated behaviors, there are occasionally reports of people performing complex behaviors while asleep, although their legitimacy is often disputed. Sleepwalkers often have little or no memory of the incident, as their consciousness has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Everett Millais
Sir John Everett Millais, 1st Baronet, ( , ; 8 June 1829 – 13 August 1896) was an English painter and illustrator who was one of the founders of the Pre-Raphaelite Brotherhood. He was a child prodigy who, aged eleven, became the youngest student to enter the Royal Academy Schools. The Pre-Raphaelite Brotherhood was founded at his family home in London, at 83 Gower Street (now number 7). Millais became the most famous exponent of the style, his painting '' Christ in the House of His Parents'' (1849–50) generating considerable controversy, and he produced a picture that could serve as the embodiment of the historical and naturalist focus of the group, ''Ophelia'', in 1851–52. By the mid-1850s, Millais was moving away from the Pre-Raphaelite style to develop a new form of realism in his art. His later works were enormously successful, making Millais one of the wealthiest artists of his day, but some former admirers including William Morris saw this as a sell-out (Millais ...

Restless Leg Syndrome
Restless legs syndrome (RLS), also known as Willis-Ekbom disease (WED), is generally a long-term disorder that causes a strong urge to move one's legs. There is often an unpleasant feeling in the legs that improves somewhat by moving them. This is often described as aching, tingling, or crawling in nature. Occasionally, arms may also be affected. The feelings generally happen when at rest and therefore can make it hard to sleep. Due to the disturbance in sleep, people with RLS may have daytime sleepiness, low energy, irritability and a depressed mood. Additionally, many have limb twitching during sleep. RLS is not the same as habitual foot tapping or leg rocking. Risk factors for RLS include low iron levels, kidney failure, Parkinson's disease, diabetes mellitus, rheumatoid arthritis, pregnancy and celiac disease. A number of medications may also trigger the disorder including antidepressants, antipsychotics, antihistamines, and calcium channel blockers. There are two main typ ...

Serotonergic Agents
Serotonergic () or serotoninergic () means "pertaining to or affecting serotonin". Serotonin is a neurotransmitter. A synapse is serotonergic if it uses serotonin as its neurotransmitter. A serotonergic neuron ''produces'' serotonin. A substance is serotonergic if it produces its effects via interactions with the serotonin system, such as by stimulating or blocking neurotransmission. A serotonergic or serotoninergic agent is any chemical that modifies the effects of serotonin in the body. Some different types of serotonergics drugs include the following: * Serotonin receptor agonists and antagonists * Serotonin reuptake inhibitors * Serotonin releasing agent A serotonin releasing agent (SRA) is a type of drug that induces the release of serotonin into the neuronal synaptic cleft. A selective serotonin releasing agent (SSRA) is an SRA with less significant or no efficacy in producing neurotransmitter e ...s See also References Parasympathetic nervous system Neurochem ...

Antidepressants
Antidepressants are a class of medication used to treat major depressive disorder, anxiety disorders, chronic pain conditions, and to help manage addictions. Common side-effects of antidepressants include dry mouth, weight gain, dizziness, headaches, sexual dysfunction, and emotional blunting. There is a slight increased risk of suicidal thinking and behavior when taken by children, adolescents, and young adults. Discontinuation syndrome may occur after stopping any antidepressant which resembles recurrent depression. Some research regarding the effectiveness of antidepressants for depression in adults has found benefits, whilst other research has not. Evidence of benefit in children and adolescents is unclear. The twenty-one most commonly prescribed antidepressant medications are more effective than placebo for the short-term (acute) treatments of adults with major depressive disorder. There is debate in the medical community about how much of the observed effects of antidepr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serotonin
Serotonin () or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter. Its biological function is complex and multifaceted, modulating mood, cognition, reward, learning, memory, and numerous physiological processes such as vomiting and vasoconstriction. Approximately 90% of the serotonin that the body produces is in the intestinal tract. Biochemically, the indoleamine molecule derives from the amino acid tryptophan, via the (rate-limiting) hydroxylation of the 5 position on the ring (forming the intermediate 5-hydroxytryptophan), and then decarboxylation to produce serotonin. Serotonin is primarily found in the enteric nervous system located in the gastrointestinal tract (GI tract). However, it is also produced in the central nervous system (CNS), specifically in the raphe nuclei located in the brainstem, Merkel cells located in the skin, pulmonary neuroendocrine cells and taste receptor cells in the tongue. Additionally, serotonin is stored in blood platelets a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetic Linkage
Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction. Two genetic markers that are physically near to each other are unlikely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be more ''linked'' than markers that are far apart. In other words, the nearer two genes are on a chromosome, the lower the chance of recombination between them, and the more likely they are to be inherited together. Markers on different chromosomes are perfectly ''unlinked'', although the penetrance of potentially deleterious alleles may be influenced by the presence of other alleles, and these other alleles may be located on other chromosomes than that on which a particular potentially deleterious allele is located. Genetic linkage is the most prominent exception to Gregor Mendel's Law of Independent Assortment. The first experiment to demonstra ...

Daily Mirror
The ''Daily Mirror'' is a British national daily tabloid. Founded in 1903, it is owned by parent company Reach plc. From 1985 to 1987, and from 1997 to 2002, the title on its masthead was simply ''The Mirror''. It had an average daily print circulation of 716,923 in December 2016, dropping to 587,803 the following year. Its Sunday sister paper is the ''Sunday Mirror''. Unlike other major British tabloids such as '' The Sun'' and the ''Daily Mail'', the ''Mirror'' has no separate Scottish edition; this function is performed by the '' Daily Record'' and the '' Sunday Mail'', which incorporate certain stories from the ''Mirror'' that are of Scottish significance. Originally pitched to the middle-class reader, it was converted into a working-class newspaper after 1934, in order to reach a larger audience. It was founded by Alfred Harmsworth, who sold it to his brother Harold Harmsworth (from 1914 Lord Rothermere) in 1913. In 1963 a restructuring of the media interests of the Harm ...

Tourette Syndrome
Tourette syndrome or Tourette's syndrome (abbreviated as TS or Tourette's) is a common neurodevelopmental disorder that begins in childhood or adolescence. It is characterized by multiple movement (motor) tics and at least one vocal (phonic) tic. Common tics are blinking, coughing, throat clearing, sniffing, and facial movements. These are typically preceded by an unwanted urge or sensation in the affected muscles known as a premonitory urge, can sometimes be suppressed temporarily, and characteristically change in location, strength, and frequency. Tourette's is at the more severe end of a spectrum of tic disorders. The tics often go unnoticed by casual observers. Tourette's was once regarded as a rare and bizarre syndrome and has popularly been associated with coprolalia (the utterance of obscene words or socially inappropriate and derogatory remarks). It is no longer considered rare; about 1% of school-age children and adolescents are estimated to have Tourette's, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Migraine
Migraine (, ) is a common neurological disorder characterized by recurrent headaches. Typically, the associated headache affects one side of the head, is pulsating in nature, may be moderate to severe in intensity, and could last from a few hours to three days. Non-headache symptoms may include nausea, vomiting, and sensitivity to light, sound, or smell. The pain is generally made worse by physical activity during an attack,as PDF although regular physical exercise may prevent future attacks. Up to one-third of people affected have : typically, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neurosis
Neurosis is a class of functional mental disorders involving chronic distress, but neither delusions nor hallucinations. The term is no longer used by the professional psychiatric community in the United States, having been eliminated from the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM) in 1980 with the publication of DSM III. However, it is still used in the ICD-10 Chapter V F40–48. Neurosis should not be mistaken for ''psychosis'', which refers to a loss of touch with reality. Nor should it be mistaken for ''neuroticism'', a fundamental personality trait proposed in the Big Five personality traits theory. Etymology The term is derived from the Greek word ''neuron'' (νεῦρον, 'nerve') and the suffix ''-osis'' (-ωσις, 'diseased' or 'abnormal condition'). The term ''neurosis'' was coined by Scottish doctor William Cullen in 1769 to refer to "disorders of sense and motion" caused by a "general affection of the nervous system." Cullen used the te ...

Schizophrenia
Schizophrenia is a mental disorder characterized by continuous or relapsing episodes of psychosis. Major symptoms include hallucinations (typically hearing voices), delusions, and disorganized thinking. Other symptoms include social withdrawal, decreased emotional expression, and apathy. Symptoms typically develop gradually, begin during young adulthood, and in many cases never become resolved. There is no objective diagnostic test; diagnosis is based on observed behavior, a history that includes the person's reported experiences, and reports of others familiar with the person. To be diagnosed with schizophrenia, symptoms and functional impairment need to be present for six months ( DSM-5) or one month (ICD-11). Many people with schizophrenia have other mental disorders, especially substance use disorders, depressive disorders, anxiety disorders, and obsessive–compulsive disorder. About 0.3% to 0.7% of people are diagnosed with schizophrenia during their lifetim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
