Disruptive Mood Dysregulation Disorder
Disruptive mood dysregulation disorder (DMDD) is a mental disorder in children and adolescents characterized by a persistently irritable or angry mood and frequent temper outbursts that are disproportionate to the situation and significantly more severe than the typical reaction of same-aged peers. DMDD was added to the DSM-5 as a type of depressive disorder diagnosis for youths. The symptoms of DMDD resemble those of attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), anxiety disorders, and childhood bipolar disorder . DMDD first appeared as a disorder in the ''Diagnostic and Statistical Manual of Mental Disorders'', Fifth Edition (DSM-5) in 2013 and is classified as a mood disorder. Treatments include medication to manage mood symptoms as well as individual and family therapy to address emotion-regulation skills. Children with DMDD are at risk for developing depression and anxiety later in life. Signs and symptoms Children with DMDD show s ...

Psychiatry
Psychiatry is the medical specialty devoted to the diagnosis, prevention, and treatment of mental disorders. These include various maladaptations related to mood, behaviour, cognition, and perceptions. See glossary of psychiatry. Initial psychiatric assessment of a person typically begins with a case history and mental status examination. Physical examinations and psychological tests may be conducted. On occasion, neuroimaging or other neurophysiological techniques are used. Mental disorders are often diagnosed in accordance with clinical concepts listed in diagnostic manuals such as the ''International Classification of Diseases'' (ICD), edited and used by the World Health Organization (WHO) and the widely used '' Diagnostic and Statistical Manual of Mental Disorders'' (DSM), published by the American Psychiatric Association (APA). The fifth edition of the DSM (DSM-5) was published in May 2013 which re-organized the larger categories of various diseases and expanded upon the p ...

ADHD
Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by excessive amounts of inattention, hyperactivity, and impulsivity that are pervasive, impairing in multiple contexts, and otherwise age-inappropriate. ADHD symptoms arise from executive dysfunction, and emotional dysregulation is often considered a core symptom. In children, problems paying attention may result in poor school performance. ADHD is associated with other neurodevelopmental and mental disorders as well as some non-psychiatric disorders, which can cause additional impairment, especially in modern society. Although people with ADHD struggle to focus on tasks they are not particularly interested in completing, they are often able to maintain an unusually prolonged and intense level of attention for tasks they do find interesting or rewarding; this is known as hyperfocus. The precise causes of ADHD are unknown in the majority of cases. Genetic factors play an import ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amygdala
The amygdala (; plural: amygdalae or amygdalas; also '; Latin from Greek, , ', 'almond', 'tonsil') is one of two almond-shaped clusters of nuclei located deep and medially within the temporal lobes of the brain's cerebrum in complex vertebrates, including humans. Shown to perform a primary role in the processing of memory, decision making, and emotional responses (including fear, anxiety, and aggression), the amygdalae are considered part of the limbic system. The term "amygdala" was first introduced by Karl Friedrich Burdach in 1822. Structure The regions described as amygdala nuclei encompass several structures of the cerebrum with distinct connectional and functional characteristics in humans and other animals. Among these nuclei are the basolateral complex, the cortical nucleus, the medial nucleus, the central nucleus, and the intercalated cell clusters. The basolateral complex can be further subdivided into the lateral, the basal, and the accessory basal nucle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Functional MRI
Functional magnetic resonance imaging or functional MRI (fMRI) measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases. The primary form of fMRI uses the blood-oxygen-level dependent (BOLD) contrast, discovered by Seiji Ogawa in 1990. This is a type of specialized brain and body scan used to map neural activity in the brain or spinal cord of humans or other animals by imaging the change in blood flow (hemodynamic response) related to energy use by brain cells. Since the early 1990s, fMRI has come to dominate brain mapping research because it does not involve the use of injections, surgery, the ingestion of substances, or exposure to ionizing radiation. This measure is frequently corrupted by noise from various sources; hence, statistical procedures are used to extract the underlying signal. ...

Antisocial Personality Disorder
Antisocial personality disorder (ASPD or infrequently APD) is a personality disorder characterized by a long-term pattern of disregard of, or violation of, the rights of others as well as a difficulty sustaining long-term relationships. Lack of empathy is often apparent, as well as a history of rule-breaking that can sometimes include law-breaking, a tendency towards substance abuse, and impulsive and aggressive behavior. Antisocial behaviors often have their onset before the age of 8, and in nearly 80% of ASPD cases, the subject will develop their first symptoms by age 11. The prevalence of ASPD peaks in people age 24 to 44 years old, and often decreases in people age 45 to 64 years. In the United States, the rate of antisocial personality disorder in the general population is estimated between 0.5 and 3.5 percent. In a study, a random sampling of 320 newly incarcerated offenders found ASPD was present in over 35 percent of those surveyed. Personality disorders are a class o ...

Remorse
Remorse is a distressing emotion experienced by an individual who regrets actions which they have done in the past that they deem to be shameful, hurtful, or wrong. Remorse is closely allied to guilt and self-directed resentment. When a person regrets an earlier action or failure to act, it may be because of remorse or in response to various other consequences, including being punished for the act or omission. People may express remorse through apologies, trying to repair the damage they've caused, or self-imposed punishments. In a legal context, the perceived remorse of an offender is assessed by Western justice systems during trials, sentencing, parole hearings, and in restorative justice. However, there are epistemological problems with assessing an offender's level of remorse. A person who is incapable of feeling remorse is often diagnosed with antisocial personality disorder, as characterized in the DSM IV-TR. In general, a person needs to be unable to feel fear, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emotional Dysregulation
Emotional dysregulation is a range of emotional responses that are poorly modulated and do not lie within a desirable scope of emotive response. Emotional dysregulation can be associated with an experience of early psychological trauma, brain injury, or chronic maltreatment (such as child abuse, child neglect, or institutional neglect/abuse), and associated disorders such as reactive attachment disorder. Emotional dysregulation may be present in people with psychiatric disorders such as attention deficit hyperactivity disorder, autism spectrum disorders, bipolar disorder, borderline personality disorder, complex post-traumatic stress disorder, and fetal alcohol spectrum disorders.Schore, A., (2003). ''Affect dysregulation and disorders of the self''. New York: Norton. In such cases as borderline personality disorder and complex post-traumatic stress disorder, hypersensitivity to emotional stimuli causes a slower return to a normal emotional state. This is manifested biological ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conduct Disorder
Conduct disorder (CD) is a mental disorder diagnosed in childhood or adolescence that presents itself through a repetitive and persistent pattern of behavior that includes theft, lies, physical violence that may lead to destruction, and reckless breaking of rules, in which the basic rights of others or major age-appropriate norms are violated. These behaviors are often referred to as " antisocial behaviors." It is often seen as the precursor to antisocial personality disorder, which by definition cannot be diagnosed until the individual is 18 years old. Conduct disorder may result from parental rejection and neglect and can be treated with family therapy, as well as behavioral modifications and pharmacotherapy. Conduct disorder is estimated to affect 51.1 million people globally Signs and symptoms One of the symptoms of conduct disorder is a lower level of fear. Research performed on the impact of toddlers exposed to fear and distress shows that negative emotionality (fear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Generalized Anxiety Disorder
Generalized anxiety disorder (GAD) is a mental and behavioral disorder, specifically an anxiety disorder characterized by excessive, uncontrollable and often irrational worry about events or activities. Worry often interferes with daily functioning, and individuals with GAD are often overly concerned about everyday matters such as health, finances, death, family, relationship concerns, or work difficulties."What Is Generalized Anxiety Disorder?" National Institute of Mental Health. Accessed 28 May 2008. Symptoms may include excessive worry, restlessness, , exhaustion, irritability, sweating, and |
Hypomanic Episode
Hypomania (literally "under mania" or "less than mania") is a mental and behavioural disorder, characterised essentially by an apparently non-contextual elevation of mood ( euphoria) that contributes to persistently disinhibited behaviour. The individual with the condition may experience irritability, not necessarily less severe than full mania; in fact, the presence of marked irritability is a documented feature of hypomanic and mixed episodes in Bipolar type II. 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. Characteristic behaviors of persons experiencing hypomania are a notable decrease in the need for sleep, an overall increase in energy, unusual behaviors and actions, and a markedly distinctive increase in talkativeness and confidence, commonly exhibited with a flight of creative ideas. Other sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manic Episode
Mania, also known as manic syndrome, is a mental and behavioral disorder defined as a state of abnormally elevated arousal, affect, and energy level, or "a state of heightened overall activation with enhanced affective expression together with lability of affect." During a manic episode, an individual will experience rapidly changing emotions and moods, highly influenced by surrounding stimuli. Although mania is often conceived as a "mirror image" to depression, the heightened mood can be either euphoric or dysphoric. As the mania intensifies, irritability can be more pronounced and result in anxiety or anger. The symptoms of mania include elevated mood (either euphoric or irritable), flight of ideas and pressure of speech, increased energy, decreased need and desire for sleep, and hyperactivity. They are most plainly evident in fully developed hypomanic states. However, in full-blown mania, they undergo progressively severe exacerbations and become more and more obscured ...

Oppositional Defiant Disorder
Oppositional defiant disorder (ODD) is listed in the DSM-5 under ''Disruptive, impulse-control, and conduct disorders'' and defined as "a pattern of angry/irritable mood, argumentative/defiant behavior, or vindictiveness". This behavior is usually targeted toward peers, parents, teachers, and other authority figures. Unlike conduct disorder (CD), those with ODD do not show patterns of aggression towards people or animals, destruction of property, theft, or deceit. It has certain links to attention deficit hyperactivity disorder (ADHD), and as many as one half of children with ODD also fulfill the diagnostic criteria for ADHD. History Oppositional defiant disorder was first defined in the ''DSM-III'' (1980). Since the introduction of ODD as an independent disorder, the field trials to inform its definition have included predominantly male subjects. Some clinicians have debated whether the diagnostic criteria would be clinically relevant for use with women, and furthermore, so ...
