Schizophrenia (/ˌskɪtsɵˈfrɛniə/ or /ˌskɪtsɵˈfriːniə/) is a mental disorder often characterized by abnormal social behavior and failure to recognize what is real. Common symptoms include false beliefs, unclear or confused thinking, auditory hallucinations, reduced social engagement and emotional expression, and lack of motivation. Diagnosis is based on observed behavior and the person's reported experiences. Genetics and early environment, as well as psychological and social processes, appear to be important contributory factors. Some recreational and prescription drugs appear to cause or worsen symptoms. The many possible combinations of symptoms have triggered debate about whether the diagnosis represents a single disorder or a number of separate syndromes. Symptoms Self-portrait of a person with schizophrenia, representing that individual's perception of the distorted experience of reality in the disorder Positive and negative Onset Causes Genetic Environment Substance use Mechanisms Diagnosis

Syndrome Definition[edit] A syndrome can refer to the traits that suggest the presence of a disease, or indicate a greater likelihood of developing the disease.[2] The term syndrome derives from the Greek σύνδρομον, meaning "concurrence".[3] Usage[edit] Medicine[edit] August Natterer August Natterer (1868–1933), also known as Neter, was a schizophrenic German outsider artist. Hexenkopf (The Witch's Head), ca. 1915 Biography[edit] August Natterer, given the pseudonym Neter by his psychiatrist to protect him and his family from the immense social stigma associated with mental illness at the time, was born in 1868 in Schornreute near Ravensburg, Germany, the son of a clerk and the youngest of nine children. Natterer studied engineering, got married, travelled widely, and had a successful career as an electrician but was suddenly stricken with delusions and anxiety attacks.[1] On April Fool's Day 1907 he had a pivotal hallucination of the Last Judgment during which "10,000 images flashed by in half an hour.

Psychiatry Initial psychiatric assessment of a person typically begins with a case history and mental status examination. Psychological tests and physical examinations may be conducted, including on occasion the use of neuroimaging or other neurophysiological techniques. Mental disorders are broadly diagnosed in accordance with criteria listed in diagnostic manuals such as the widely used Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association, and the International Classification of Diseases (ICD), edited and used by the World Health Organization.

Schizophrenia Definition Schizophrenia is a chronic and severe mental disorder that affects how a person thinks, feels, and behaves. People with schizophrenia may seem like they have lost touch with reality. Although schizophrenia is not as common as other mental disorders, the symptoms can be very disabling. Signs and Symptoms Symptoms of schizophrenia usually start between ages 16 and 30. Neurasthenia Neurasthenia is a term that was first used at least as early as 1829 to label a mechanical weakness of the actual nerves, rather than the more metaphorical "nerves" referred to by George Miller Beard later. Neurasthenia is currently a diagnosis in the World Health Organization's International Classification of Diseases (and the Chinese Society of Psychiatry's Chinese Classification of Mental Disorders). However, it is no longer included as a diagnosis in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders. Americans were said to be particularly prone to neurasthenia, which resulted in the nickname "Americanitis"[2] (popularized by William James). Another, rarely used, term for neurasthenia is nervosism.[3]

Teen Slender Man Stabber Claims Sexual Abuse in Hospital, Denied House Arrest Last week, a Wisconsin judge denied the teenage girls involved in the so-called "Slender Man stabbing" their request to live under house arrest. The girls were hoping to return home while awaiting trial, but instead both will stay in custody, their bail set at $500,000 each. Thirteen-year-old Morgan Geyser and 14-year-old Anissa Weier were arrested in May 2014 after reportedly stabbing their friend, Payton Leutner, 19 times. Leutner survived. Geyser and Weier said they were acting under the orders of Slender Man, a fictional Internet character who they claim told them to murder Leutner. Drapetomania Drapetomania was a supposed mental illness described by American physician Samuel A. Cartwright in 1851 that caused black slaves to flee captivity.[1]:41 Today, drapetomania is considered an example of pseudoscience,[2]:2 and part of the edifice of scientific racism.[3] Etymology[edit] The term derives from the Greek δραπετης (drapetes, "a runaway [slave]") + μανια (mania, "madness, frenzy").[4] Description[edit]

CNS - 'Slenderman' Stabber Breaks Down in Court WAUKESHA, Wis. (CN) — For the first time since she was charged with the near-fatal stabbing of her middle-school classmate, Morgan Geyser cried in court Friday as the judge denied her request to live under house arrest while awaiting trial. Waukesha County Circuit Court Judge Michael Bohren was no more merciful with Geyser's co-defendant, Anissa Weier, who admittedly collaborated with Geyser in the May 2014 stabbing of their school friend at a forest near her house. Payton Leutner survived the attack after a bicyclist found her crawling from the forest with 19 stab wounds. All the girls were 12 at the time of the attempted murder, as it has been charged. The assailants have claimed they did it to please Slenderman, a fictional internet boogeyman they believed they could live with if they completed the murder.
