Mania in the context of Hallucination

Euphoria (/juːˈfɔːriə/ yoo-FOR-ee-ə) is the experience (or affect) of pleasure or excitement and intense feelings of well-being and happiness. Certain natural rewards and social activities, such as aerobic exercise, laughter, listening to or making music and dancing, can induce a state of euphoria. Euphoria is also a symptom of certain neurological or neuropsychiatric disorders, such as mania. Romantic love and components of the human sexual response cycle are also associated with the induction of euphoria. Certain drugs, many of which are addictive, can cause euphoria, which at least partially motivates their recreational use.

Hedonic hotspots – i.e., the pleasure centers of the brain – are functionally linked. Activation of one hotspot results in the recruitment of the others. Inhibition of one hotspot results in the blunting of the effects of activating another hotspot. Therefore, the simultaneous activation of every hedonic hotspot within the reward system is believed to be necessary for generating the sensation of an intense euphoria.

A mood disorder, also known as an affective disorder, is any of a group of conditions of mental and behavioral disorder where the main underlying characteristic is a disturbance in the person's mood. The classification is in the Diagnostic and Statistical Manual of Mental Disorders (DSM) and International Classification of Diseases (ICD).

Mood disorders fall into seven groups, including: 1. abnormally elevated mood, such as mania or hypomania; 2. depressed mood, of which the best-known and most researched is major depressive disorder (MDD) (alternatively known as clinical depression, unipolar depression, or major depression); and 3. moods which cycle between mania and depression, known as bipolar disorder (BD) (formerly known as manic depression). 4. There are several subtypes of depressive disorders or psychiatric syndromes featuring less severe symptoms such as dysthymic disorder (similar to MDD, but longer lasting and more persistent, though often milder) and cyclothymic disorder (similar to but milder than BD).

Arithmomania (from Greek arithmós, "number", and maníā, "compulsion") is a mental disorder that may be seen as an expression of obsessive–compulsive disorder (OCD). Individuals experiencing this disorder have a strong need to count their actions or objects in their surroundings.

For example, individuals with arithmomania may feel compelled to count steps while climbing or descending stairs or to tally the number of letters in words. They often feel compelled to repeat an action a specific number of times to avert a perceived catastrophe. Other examples include counting tiles on floors or ceilings, lines on highways, or touching objects a specific number of times, such as doorknobs or tables.

Bipolar disorder (BD), previously known as manic depression, is a mental disorder characterized by periods of depression and 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 does not significantly affect functioning, it is called hypomania. During mania, an individual behaves or feels abnormally energetic, happy, or irritable, and often makes impulsive decisions with little regard for the consequences. There is usually sleep disturbance during manic phases. During periods of depression, the individual may experience crying, have a negative outlook, and demonstrate poor eye contact. Over a period of 20 years, 6% of those with BD died by suicide, with about one-third attempting suicide in their lifetime. Among those with BD, 40–50% overall and 78% of adolescents engaged in self-harm.

While the causes of this mood disorder are not clearly understood, genetic and environmental factors are thought to play a role. Genetic factors may account for up to 70–90% of the risk of developing BD. Environmental risks include a history of child abuse and long-term stress. The condition is classified as bipolar I disorder if there has been at least one manic episode, with or without depressive episodes, and as bipolar II disorder if there has been at least one hypomanic episode (but no full manic episodes) and one major depressive episode. It is classified as cyclothymia if there are hypomanic episodes with periods of depression that do not meet the criteria for major depressive episodes.If these symptoms are due to drugs or medical problems, they are not diagnosed as BD.

Electroconvulsive therapy (ECT) is a 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.

The general physical risks of ECT are similar to those of brief general anesthesia. Immediately following treatment, the most common adverse effects are confusion and transient memory loss. Among treatments for severely depressed pregnant women, ECT is one of the least harmful to the fetus.

A thought disorder (TD) is a multifaceted construct that reflects abnormalities in thinking, language, and communication. Thought disorders encompass a range of thought and language difficulties and include poverty of ideas, perverted logic (illogical or delusional thoughts), word salad, delusions, derailment, pressured speech, poverty of speech, tangentiality, verbigeration, and thought blocking. One of the first known public presentations of a thought disorder, specifically obsessive–compulsive disorder (OCD) as it is now known, was in 1691, when Bishop John Moore gave a speech before Queen Mary II, about "religious melancholy."

Two subcategories of thought disorder are content-thought disorder, and formal thought disorder. CTD has been defined as a thought disturbance characterized by multiple fragmented delusions. A formal thought disorder is a disruption of the form (or structure) of thought.Also known as disorganized thinking, FTD affects the form (rather than the content) of thought. FTD results in disorganized speech and is recognized as a key feature of schizophrenia and other psychotic disorders (including mood disorders, dementia, mania, and neurological diseases). Unlike hallucinations and delusions, it is an observable, objective sign of psychosis. FTD is a common core symptom of a psychotic disorder, and may be seen as a marker of severity and as an indicator of prognosis. It reflects a cluster of cognitive, linguistic, and affective disturbances that have generated research interest in the fields of cognitive neuroscience, neurolinguistics, and psychiatry.

Ideas of reference and delusions of reference describe the phenomenon of an individual experiencing innocuous events or mere coincidences and believing they have strong personal significance. It is "the notion that everything one perceives in the world relates to one's own destiny", usually in a negative and hostile manner.

In psychiatry, delusions of reference form part of the diagnostic criteria for psychotic illnesses such as schizophrenia, delusional disorder, schizoaffective disorder and bipolar disorder with mania, as well as for schizotypal personality disorder. To a lesser extent, their presence can be a hallmark of paranoid personality disorder, as well as body dysmorphic disorder. They can be found in autism during periods of intense stress. They can also be caused by intoxication, such as from stimulants like methamphetamine. Psychedelics like psilocybin have also been reported to produce ideas of reference during experiences.

Hypomania (literally "under mania" or "less than mania") is a psychiatric behavioral syndrome characterized essentially by an apparently non-contextual elevation of mood (i.e., euphoria) that contributes to persistently disinhibited behavior.

The individual with the condition may experience irritability, not necessarily less severe than full mania; the presence of marked irritability is a documented feature of hypomanic and mixed episodes in bipolar II disorder. According to DSM-5 criteria, hypomania is distinct from mania in that there is no significant functional impairment; mania, by DSM-5 definition, does include significant functional impairment and may have psychotic features.

Cyclothymia (/ˌsaɪkləˈθaɪmiə/, siy-kluh-THIY-mee-uh), also known as cyclothymic disorder, psychothemia / psychothymia, bipolar III, affective personality disorder and cyclothymic personality disorder, is a mental and behavioural disorder that involves numerous periods of symptoms of depression and periods of symptoms of elevated mood. These symptoms, however, are not sufficient to indicate a major depressive episode or a manic episode. Symptoms must last for more than one year in children and two years in adults.

The cause of cyclothymia is unknown. Risk factors include a family history of bipolar disorder. Cyclothymia differs from bipolar disorder in the fact that major depression and mania are not found.

Surgency is a temperament dimension that considers an individual’s disposition toward positive affect. The APA Dictionary of Psychology defines it as "a personality trait marked by cheerfulness, responsiveness, spontaneity, and sociability but at a level below that of extraversion or mania."

Reginald Robin Farquharson (3 October 1930 – 1 April 1973) was an academic whose interest in mathematics and politics led him to work on game theory and social choice theory. He wrote an influential analysis of voting systems in his doctoral thesis, later published as Theory of Voting, and conjectured the Gibbard–Satterthwaite theorem together with the philosopher and logician Michael Dummett.

Farquharson diagnosed himself as suffering from bipolar disorder (manic depression), and episodes of mania made it difficult for him to obtain a permanent university position and also resulted in him losing commercial employment. In later years, he dropped out of mainstream society, and became a prominent counter-cultural figure in late-1960s London. Farquharson wrote an account of his unconventional life in his 1968 book, Drop Out!, in which he described a week of being homeless in London.In 1973 he died from burns associated with an arson, for which two persons were convicted of unlawful killing.

Potomania (From Greek pōtō "drink (liquor)" + mania) is a specific hypo-osmolality syndrome related to massive consumption of beer, which is poor in solutes and electrolytes. With little food or other sources of electrolytes, consumption of large amounts of beer or other dilute alcoholic beverages leads to electrolyte disturbances, where the body does not have enough nutrients known as electrolytes, namely sodium, potassium, and magnesium. The symptoms of potomania are similar to other causes of hyponatremia and include dizziness, muscular weakness, neurological impairment and seizures, all related to hyponatremia and hypokalaemia. While the symptoms of potomania are similar to other causes of hyponatremia and acute water intoxication, it should be considered an independent clinical entity because of its often chronic nature of onset, pathophysiology, and presentation of symptoms.

Fluoxetine, sold under the brand name Prozac, among others, is an antidepressant medication of the selective serotonin reuptake inhibitor (SSRI) class used for the treatment of major depressive disorder, anxiety, obsessive–compulsive disorder (OCD), panic disorder, premenstrual dysphoric disorder, and bulimia nervosa. It is also approved for treatment of major depressive disorder in adolescents and children 8 years of age and over. It has also been used to treat premature ejaculation. Fluoxetine is taken by mouth.

Common side effects include loss of appetite, nausea, diarrhea, headache, trouble sleeping, dry mouth, and sexual dysfunction. Serious side effects include serotonin syndrome, mania, seizures, an increased risk of suicidal behavior, and an increased risk of bleeding. Antidepressant discontinuation syndrome is less likely to occur with fluoxetine than with other antidepressants. Fluoxetine taken during pregnancy is associated with a significant increase in congenital heart defects in newborns. It has been suggested that fluoxetine therapy may be continued during breastfeeding if it was used during pregnancy or if other antidepressants were ineffective.
