Euthymia (medicine)

Last updated

In psychiatry and psychology, euthymia is a normal, tranquil mental state or mood. [1] People with mood disorders, including major depressive disorder and bipolar disorder, experience euthymia as a stable mood state that is neither depressive nor manic. Achieving and maintaining euthymia is the goal of treatment for bipolar patients in particular. [2]

Etymology

The term euthymia is derived from the Greek words ευeu'well' and θυμόςthymos'spirit'. [3] The word “thymos” had four meanings: life energy, feelings/passions, desire/will, and thought/intelligence; and was also tied to the social dimension e.g. seeking honor from others. [3] The verb form "euthymeo” meant both “I am happy, in good spirits” and “I make others happy, I reassure and encourage”. [2]

Democritus, who coined the philosophical concept of euthymia, said that euthymia is achieved when "one is satisfied with what is present and available, taking little heed of people who are envied and admired and observing the lives of those who suffer and yet endure". This was later amended in the translation given by the Roman philosopher Seneca the Younger in which euthymia means a state of internal calm and contentment. Seneca was also the first to link the state of euthymia to a learning process; in order to achieve it, one must be aware of psychological well-being. Seneca’s definition included a caveat[ clarification needed ] about detachment from current events. Later, the Greek biographer Plutarch removed this caveat with his definition which focused more on learning from adverse events. [2]

History

In 1958, Marie Jahoda gave a modern clinical definition of mental health in the terms of positive symptoms by outlining the criteria for mental health: "autonomy (regulation of behavior from within), environmental mastery, satisfactory interactions with other people and the milieu, the individual’s style and degree of growth, development or self-actualization, the attitudes of an individual toward his/her own self". In her definition she acknowledged the absence of disease as being necessary, but not enough, to constitute positive mental health, or euthymia. [2]

Expansion of clinical concept

The traditional clinical concept of euthymia is an absence of disorder. This turns out to be insufficient: patients considered to be in remission, i.e. not displaying symptoms meeting the threshold for diagnosis, still show impairments in psychological well-being compared to healthy subjects. [4] : 40 

Carol Ryff (1989) was the first to develop a comprehensive scale that could assess euthymia: the six-factor model of psychological well-being. The 84-item scale includes facets of self-acceptance, positive relations with others, autonomy, environmental mastery, purpose in life, and personal growth. [2] Garamoni et al (1991) described euthymia as having a balance between the positive and negative in six dimensions of cognition and affects similar to the Ryff factors. Having too much positivity in one factor is not euthymia: for example, a person with too little "purpose in life" would lack a sense of meaning in life, while one with too much would have unrealistic expectations and hopes. [4] : 41 

The concept of resilience (or, resistance to stress) was added again in the 2000s by authors in the field. Fava and Bech (2016)'s definition can be seen as a modern example: [4] : 42 

Medical applications of the expanded concept

In 1987, Kellner R published the Symptom Questionnaire, containing 24 items referring to positive feelings and 68 referring to the negative. With the inclusion of positive feelings such as relaxation and friendliness, the SQ was found to be more sensitive to the effects of psychotrophic medication. [4] : 41  A number of other scales, such as the WHO-5, PWB, AAQ-II, CIE, have been developed to also measure the positive side of euthymia. [4] : 43 

Macro-analysis and micro-analysis are techniques used by clinicians to combine the assessments of psychological well-being and distress. Using both fields may offer more insight into the planning of treatment: for example, well-being therapy (WBT) can be used to help a patient self-observe and increase periods of well-being, while cognitive behavioral therapy (CBT) can be used to target distress. [4] : 45  Other therapies that focus on aspects of well-being include mindfulness-based cognitive therapy (MBCT), acceptance and commitment therapy (ACT) which focus on flexibility, and the less-proven Pedasky and Mooney's strengths-based CBT and forgiveness therapy. [4] : 46 

A few clinical trials have been done using a sequential model, where patients who have responded to antidepressants are tapered off the drug and then given a combination cognitive-wellbeing therapy. Although the results have been impressive with regard to relapse rates, it is unclear how much is due to this added well-being component. [4] : 46  In a different trial setup, anxiety patients who have responded to behavioral theapy and mood disorder patients who have responded to medication are assigned to either CBT or WBT for residual symptoms. While both achieved a significant reduction of symptoms, WBT provided more benefit in terms of observer rating and PWB scores. WBT may also be applicable to cyclothymic disorder. MBCT seem to be an effective add-on to treatment-as-usual in treatment-resistant depression. [4] : 47

Cognitive behavioral therapy (CBT) is a form of psychotherapy that aims to reduce symptoms of various mental health conditions, primarily depression, PTSD and anxiety disorders. Cognitive behavioral therapy focuses on challenging and changing cognitive distortions and their associated behaviors to improve emotional regulation and develop personal coping strategies that target solving current problems. Though it was originally designed to treat depression, its uses have been expanded to include many issues and the treatment of many mental health and other conditions, including anxiety, substance use disorders, marital problems, ADHD, and eating disorders. CBT includes a number of cognitive or behavioral psychotherapies that treat defined psychopathologies using evidence-based techniques and strategies.

Psychosis is a condition of the mind or psyche that results in difficulties determining what is real and what is not real. Symptoms may include delusions and hallucinations, among other features. Additional symptoms are disorganized thinking and incoherent speech and behavior that is inappropriate for a given situation. There may also be sleep problems, social withdrawal, lack of motivation, and difficulties carrying out daily activities. Psychosis can have serious adverse outcomes.

Specific phobia is an anxiety disorder, characterized by an extreme, unreasonable, and irrational fear associated with a specific object, situation, or concept which poses little or no actual danger. Specific phobia can lead to avoidance of the object or situation, persistence of the fear, and significant distress or problems functioning associated with the fear. A phobia can be the fear of anything.

Abnormal psychology is the branch of psychology that studies unusual patterns of behavior, emotion, and thought, which could possibly be understood as a mental disorder. Although many behaviors could be considered as abnormal, this branch of psychology typically deals with behavior in a clinical context. There is a long history of attempts to understand and control behavior deemed to be aberrant or deviant, and there is often cultural variation in the approach taken. The field of abnormal psychology identifies multiple causes for different conditions, employing diverse theories from the general field of psychology and elsewhere, and much still hinges on what exactly is meant by "abnormal". There has traditionally been a divide between psychological and biological explanations, reflecting a philosophical dualism in regard to the mind–body problem. There have also been different approaches in trying to classify mental disorders. Abnormal includes three different categories; they are subnormal, supernormal and paranormal.

Schizoaffective disorder is a mental disorder characterized by symptoms of both schizophrenia (psychosis) and a mood disorder - either bipolar disorder or depression. The main diagnostic criterion is the presence of psychotic symptoms for at least two weeks without prominent mood symptoms. Common symptoms include hallucinations, delusions, disorganized speech and thinking, as well as mood episodes. Schizoaffective disorder can often be misdiagnosed when the correct diagnosis may be psychotic depression, bipolar I disorder, schizophreniform disorder, or schizophrenia. This is a problem as treatment and prognosis differ greatly for most of these diagnoses. Many people with schizoaffective disorder have other mental disorders including anxiety disorders.

<span class="mw-page-title-main">Thought disorder</span> Disorder of thought form, content or stream

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, neologisms, paralogia, 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 of thought. Also known as disorganized thinking, FTD results in disorganized speech and is recognized as a major feature of schizophrenia and other psychoses. Disorganized speech leads to an inference of disorganized thought. Thought disorders include derailment, pressured speech, poverty of speech, tangentiality, verbigeration, and thought blocking. One of the first known cases of thought disorders, or specifically OCD as it is known today, was in 1691. John Moore, who was a bishop, had a speech in front of Queen Mary II, about "religious melancholy."

A mood swing is an extreme or sudden change of mood. Such changes can play a positive or a disruptive part in promoting problem solving and in producing flexible forward planning. When mood swings are severe, they may be categorized as part of a mental illness, such as bipolar disorder, where erratic and disruptive mood swings are a defining feature.

<span class="mw-page-title-main">Creativity and mental health</span> Concept in psychology

Links between creativity and mental health have been extensively discussed and studied by psychologists and other researchers for centuries. Parallels can be drawn to connect creativity to major mental disorders including bipolar disorder, autism, schizophrenia, major depressive disorder, anxiety disorder, OCD and ADHD. For example, studies have demonstrated correlations between creative occupations and people living with mental illness. There are cases that support the idea that mental illness can aid in creativity, but it is also generally agreed that mental illness does not have to be present for creativity to exist.

Thought broadcasting is a type of delusional condition in which the affected person believes that others can hear their inner thoughts, despite a clear lack of evidence. The person may believe that either those nearby can perceive their thoughts or that they are being transmitted via mediums such as television, radio or the internet. Different people can experience thought broadcasting in different ways. Thought broadcasting is most commonly found among people who have a psychotic disorder, specifically schizophrenia.

Mental disorders are classified as a psychological condition marked primarily by sufficient disorganization of personality, mind, and emotions to seriously impair the normal psychological and often social functioning of the individual. Individuals diagnosed with certain mental disorders can be unable to function normally in society. Mental disorders may consist of several affective, behavioral, cognitive and perceptual components. The acknowledgement and understanding of mental health conditions has changed over time and across cultures. There are still variations in the definition, classification, and treatment of mental disorders.

Mindfulness-based cognitive therapy (MBCT) is an approach to psychotherapy that uses cognitive behavioral therapy (CBT) methods in conjunction with mindfulness meditative practices and similar psychological strategies. The origins to its conception and creation can be traced back to the traditional approaches from East Asian formative and functional medicine, philosophy and spirituality, birthed from the basic underlying tenets from classical Taoist, Buddhist and Traditional Chinese medical texts, doctrine and teachings.

<span class="mw-page-title-main">Psychological intervention</span>

In applied psychology, interventions are actions performed to bring about change in people. A wide range of intervention strategies exist and they are directed towards various types of issues. Most generally, it means any activities used to modify behavior, emotional state, or feelings. Psychological interventions have many different applications and the most common use is for the treatment of mental disorders, most commonly using psychotherapy. The ultimate goal behind these interventions is not only to alleviate symptoms but also to target the root cause of mental disorders.

<span class="mw-page-title-main">Bipolar disorder in children</span>

Bipolar disorder in children, or pediatric bipolar disorder (PBD), is a rare mental disorder in children and adolescents. The diagnosis of bipolar disorder in children has been heavily debated for many reasons including the potential harmful effects of adult bipolar medication use for children. PBD is similar to bipolar disorder (BD) in adults, and has been proposed as an explanation for periods of extreme shifts in mood called mood episodes. These shifts alternate between periods of depressed or irritable moods and periods of abnormally elevated moods called manic or hypomanic episodes. Mixed mood episodes can occur when a child or adolescent with PBD experiences depressive and manic symptoms simultaneously. Mood episodes of children and adolescents with PBD are different from general shifts in mood experienced by children and adolescents because mood episodes last for long periods of time and cause severe disruptions to an individual's life. There are three known forms of PBD: Bipolar I, Bipolar II, and Bipolar Not Otherwise Specified (NOS). The average age of onset of PBD remains unclear, but reported age of onset ranges from 5 years of age to 19 years of age. PBD is typically more severe and has a poorer prognosis than bipolar disorder with onset in late-adolescence or adulthood.

Bipolar II disorder (BP-II) is a mood disorder on the bipolar spectrum, characterized by at least one episode of hypomania and at least one episode of major depression. Diagnosis for BP-II requires that the individual must never have experienced a full manic episode. Otherwise, one manic episode meets the criteria for bipolar I disorder (BP-I).

<span class="mw-page-title-main">Grandiose delusions</span> Subtype of delusion

Grandiose delusions (GDs), also known as delusions of grandeur or expansive delusions, are a subtype of delusion characterized by the extraordinary belief that one is famous, omnipotent, wealthy, or otherwise very powerful or of a high status. Grandiose delusions often have a religious, science fictional, or supernatural theme. Examples include the extraordinary belief that one is a deity or celebrity, or that one possesses fantastical talents, accomplishments, or superpowers.

Cyclothymia, 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.

Cognitive behavioral therapy for insomnia (CBT-I) is a technique for treating insomnia without medications. Insomnia is a common problem involving trouble falling asleep, staying asleep, or getting quality sleep. CBT-I aims to improve sleep habits and behaviors by identifying and changing the thoughts and the behaviors that affect the ability of a person to sleep or sleep well.

A cognitive vulnerability in cognitive psychology is an erroneous belief, cognitive bias, or pattern of thought that predisposes an individual to psychological problems. The vulnerability exists before the symptoms of a psychological disorder appear. After the individual encounters a stressful experience, the cognitive vulnerability shapes a maladaptive response that increases the likelihood of a psychological disorder.

Schizophrenia is a primary psychotic disorder, whereas, bipolar disorder is a primary mood disorder which can also involve psychosis. Both schizophrenia and bipolar disorder are characterized as critical psychiatric disorders in the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5). However, because of some similar symptoms, differentiating between the two can sometimes be difficult; indeed, there is an intermediate diagnosis termed schizoaffective disorder.

Epigenetics of bipolar disorder is the effect that epigenetics has on triggering and maintaining bipolar disorder.
