Sleepwalking (Rae
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 the 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 ha ... [...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 n ...

National Library Of Medicine
The United States National Library of Medicine (NLM), operated by the United States federal government, is the world's largest medical library. Located in Bethesda, Maryland, the NLM is an institute within the National Institutes of Health. Its collections include more than seven million books, journals, technical reports, manuscripts, microfilms, photographs, and images on medicine and related sciences, including some of the world's oldest and rarest works. the acting director of the NLM was Stephen Sherry. History The precursor of the National Library of Medicine, established in 1836, was the Library of the Surgeon General's Office, a part of the office of the Surgeon General of the United States Army. The Armed Forces Institute of Pathology and its Medical Museum were founded in 1862 as the Army Medical Museum. Throughout their history the Library of the Surgeon General's Office and the Army Medical Museum often shared quarters. From 1866 to 1887, they were ho ...

Insomnia
Insomnia, also known as sleeplessness, is a sleep disorder where people have difficulty sleeping. They may have difficulty falling asleep, or staying asleep for as long as desired. Insomnia is typically followed by daytime sleepiness, low energy, irritability, and a depression (mood), depressed mood. It may result in an increased risk of accidents of all kinds as well as problems focusing and learning. Insomnia can be short term, lasting for days or weeks, or long term, lasting more than a month. The concept of the word ''insomnia'' has two distinct possibilities: insomnia disorder (ID) or insomnia symptoms, and many abstracts of randomized controlled trials and systematic reviews often underreport on which of these two possibilities the word refers to. Insomnia can occur independently or as a result of another problem. Conditions that can result in insomnia include psychological stress, chronic pain, heart failure, hyperthyroidism, heartburn, restless leg syndrome, menopause ...

Sexomnia
Sexsomnia, also known as sleep sex, is a distinct form of parasomnia, or an abnormal activity that occurs while an individual is asleep. Sexsomnia is characterized by an individual engaging in sexual acts while in non-rapid eye movement ( NREM) sleep. Sexual behaviors that result from sexsomnia are not to be mistaken with normal nocturnal sexual behaviors, which do not occur during NREM sleep. Sexual behaviors that are viewed as normal during sleep and are accompanied by extensive research and documentation include nocturnal emissions, nocturnal erections, and sleep orgasms. Sexsomnia can present in an individual with other pre-existing sleep-related disorders. Sexsomnia is most often diagnosed in males beginning in adolescence. Although they may appear to be fully awake, individuals who have sexsomnia often have no recollection of the sexual behaviors they exhibit while asleep. As a result, the individual that they share the bed with notices and reports the sexual behavior. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourette Syndrome
Tourette syndrome (TS), or simply 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 disorder, 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 Tourette syndrome#Epidemiology, estimated to hav ...

Migraine
Migraine (, ) is a complex neurological disorder characterized by episodes of moderate-to-severe headache, most often unilateral and generally associated with nausea, and light and sound sensitivity. Other characterizing symptoms may include vomiting, cognitive dysfunction, allodynia, and dizziness. Exacerbation or worsening of headache symptoms during physical activity is another distinguishing feature. Up to one-third of people with migraine experience aura, a premonitory period of sensory disturbance widely accepted to be caused by cortical spreading depression at the onset of a migraine attack. Although primarily considered to be a headache disorder, migraine is highly heterogenous in its clinical presentation and is better thought of as a spectrum disease rather than a distinct clinical entity. Disease burden can range from episodic discrete attacks to chronic disease. Migraine is believed to be caused by a mixture of environmental and genetic factors that influe ...

Neurosis
Neurosis (: neuroses) is a term mainly used today by followers of Freudian thinking to describe mental disorders caused by past anxiety, often that has been repressed. In recent history, the term has been used to refer to anxiety-related conditions more generally. The term "neurosis" is no longer used in condition names or categories by the World Health Organization's ''International Classification of Diseases'' (ICD) or the American Psychiatric Association's ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM). According to the ''American Heritage Medical Dictionary'' of 2007, the term is "no longer used in psychiatric diagnosis". Neurosis is distinguished from ''psychosis'', which refers to a loss of touch with reality. Its descendant term, ''neuroticism'', refers to a personality trait of being prone to anxiousness and mental collapse. The term "neuroticism" is also no longer used for DSM or ICD conditions; however, it is a common name for one of the Big Five p ...

Schizophrenia
Schizophrenia () is a mental disorder characterized variously by hallucinations (typically, Auditory hallucination#Schizophrenia, hearing voices), delusions, thought disorder, disorganized thinking and behavior, and Reduced affect display, flat or inappropriate affect. Symptoms Prodrome, develop gradually and typically begin during young adulthood and rarely resolve. There is no objective diagnostic test; diagnosis is based on observed behavior, a psychiatric history that includes the person's reported experiences, and reports of others familiar with the person. For a diagnosis of schizophrenia, the described symptoms need to have been present for at least six months (according to the DSM-5) or one month (according to the ICD-11). Many people with schizophrenia have other mental disorders, especially mood disorder, mood, anxiety disorder, anxiety, and substance use disorders, substance use disorders, as well as obsessive–compulsive disorder (OCD). About 0.3% to 0.7% of peo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Night Terror
Night terror, also called sleep terror, is a sleep disorder causing feelings of panic or dread and typically occurring during the first hours of stage 3–4 non-rapid eye movement (NREM) sleep and lasting for 1 to 10 minutes. It can last longer, especially in children. Sleep terror is classified in the category of NREM-related parasomnias in the International Classification of Sleep Disorders. There are two other categories: REM-related parasomnias and other parasomnias. Parasomnias are qualified as undesirable physical events or experiences that occur during entry into sleep, during sleep, or during arousal from sleep. Sleep terrors usually begin in childhood and usually decrease as age increases. Factors that may lead to sleep terrors are young age, sleep deprivation, medications, stress, fever, and intrinsic sleep disorders. The frequency and severity differ among individuals; the interval between episodes can be as long as weeks and as short as minutes or hours. This has cr ...

Apnea
Apnea (also spelled apnoea in British English) is the temporary cessation of breathing. During apnea, there is no movement of the muscles of inhalation, and the volume of the lungs initially remains unchanged. Depending on how blocked the airways are ( patency), there may or may not be a flow of gas between the lungs and the environment. If there is sufficient flow, gas exchange within the lungs and cellular respiration would not be severely affected. Voluntarily doing this is called holding one's breath. Apnea may first be diagnosed in childhood, and it is recommended to consult an ENT specialist, allergist or sleep physician to discuss symptoms when noticed; malformation and/or malfunctioning of the upper airways may be observed by an orthodontist. Cause Apnea can be involuntary—for example, drug-induced (such as by opiate toxicity), mechanically / physiologically induced (for example, by strangulation or choking), or a consequence of neurological disease or tra ...

Polysomnographies
Polysomnography (PSG) is a multi-parameter type of sleep study and a diagnostic tool in sleep medicine. The test result is called a polysomnogram, also abbreviated PSG. The name is derived from Greek and Latin roots: the Greek πολύς (''polus'' for "many, much", indicating many channels), the Latin ''somnus'' ("sleep"), and the Greek γράφειν (''graphein'', "to write"). Type I polysomnography is a sleep study performed overnight with the patient continuously monitored by a credentialed technologist. It records the physiological changes that occur during sleep, usually at night, though some labs can accommodate shift workers and people with circadian rhythm sleep disorders who sleep at other times. The PSG monitors many body functions, including brain activity (EEG), eye movements ( EOG), muscle activity or skeletal muscle activation ( EMG), and heart rhythm (ECG). After the identification of the sleep disorder sleep apnea in the 1970s, breathing functions, respiratory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sleep-related Breathing Disorder
A sleep-related breathing disorder is a sleep disorder in which abnormalities in breathing occur during sleep which may or may not be present while awake. According to the International Classification of Sleep Disorders, sleep-related breathing disorders are classified as follows: * Sleep apnea, including the more specific disorders of obstructive sleep apnea and central sleep apnea * Central hypoventilation syndromes * Obesity hypoventilation syndrome * Sleep-related hypoxemia disorder * Sleep-related hypoventilation due to a medication or substance, or due to a medical disorder * Isolated symptoms produced by breathing during sleep, including snoring and catathrenia. There are many different surgical procedures for sleep-related breathing disorders, sometimes collectively termed "sleep surgery". Severity of sleep apneas The most severe of the sleep apneas is obstructive sleep apnea. Apnea is obstructive only when polysomnography reveals a continued inspiratory effort, evidenc ...
