A mental disorderalso mental illness and criminal evaluation a mental illness  or psychiatric disorderis a behavioral or mental pattern that causes significant distress or impairment of personal functioning. Many disorders have been described, with signs and symptoms that vary widely between specific disorders. The causes of mental disorders are often unclear. Theories may incorporate findings from a range of fields.
Mental disorders are usually defined by a combination of how a person behaves, feels, perceives, or thinks. A mental disorder is one aspect of mental health.
Cultural and religious beliefs, as well as social normsshould be taken into account when making a diagnosis. Services are based in psychiatric hospitals or in the communityand assessments are carried out by mental health professionals such as psychiatrists, psychologists, and clinical social workersusing various methods such as psychometric tests but often relying on observation and questioning.
Treatments are provided by various mental health professionals. Psychotherapy and psychiatric medication are two major treatment options. Other treatments include social interventions, peer supportand self-help. In a minority of cases there might be involuntary detention or treatment. Prevention programs have been shown to reduce depression. Common mental disorders include depressionwhich affects about million, dementia which affects about 35 million, and schizophreniawhich affects about 21 million people globally.
The definition and classification of mental disorders are key issues for researchers as well as service providers and those who may be diagnosed. For a mental state to classify as a disorder, it generally needs to cause dysfunction, mental illness and criminal evaluation. It has been noted that using the term "mental" i.
According to DSM-IVa mental disorder is a psychological syndrome or pattern which is associated with distress e. DSM-IV precedes the definition with caveats, mental illness and criminal evaluation, stating that, as in the case with many medical terms, mental disorder "lacks a consistent operational definition that covers all situations", noting that different levels of abstraction can be used for medical definitions, including pathology, symptomology, deviance from a normal range, or etiology, and that the same is true for mental disorders, so that sometimes one type of definition is appropriate, and sometimes another, depending on the situation.
Both of these list categories of disorder and provide standardized criteria for diagnosis. They have deliberately converged their codes in recent revisions so that the manuals are often broadly comparable, although significant differences remain. Other classification schemes may be used in non-western cultures, for example the Chinese Classification of Mental Disordersand other manuals may be used by those of alternative theoretical persuasions, for example the Psychodynamic Diagnostic Manual.
In general, mental disorders are classified separately from neurological disorderslearning disabilities or intellectual disability. Unlike the DSM and ICD, some approaches are not based on identifying distinct categories of disorder using dichotomous symptom profiles intended to separate the abnormal from the normal. There is significant scientific debate about the relative merits of categorical versus such non-categorical or hybrid schemes, also known as continuum or dimensional models.
A spectrum approach may incorporate elements of both. In the scientific and academic literature on the definition or classification of mental disorder, one extreme argues that it is entirely a matter of value judgements including of what is normal while another proposes that it is or could be entirely objective and scientific including by reference to statistical norms.
Some neurologists argue that classification will only be reliable and valid when based on neurobiological features rather than clinical interview, while others suggest that the differing ideological and practical perspectives need to be better integrated. The DSM and ICD approach remains under attack both because of the implied causality model  and because some researchers believe it better to aim at underlying brain differences which can precede symptoms by many years.
The high degree of comorbidity between disorders in categorical models such as the DSM and ICD have led some to propose dimensional models. Studying comorbidity between disorders have demonstrated two latent unobserved factors or dimensions in the structure of mental disorders that are thought to possibly reflect etiological processes.
These two dimensions reflect a distinction mental illness and criminal evaluation internalizing disorders, such as mood or anxiety symptoms, and externalizing disorders such as behavioral or substance abuse mental illness and criminal evaluation. The p factor model supports the internalizing-externalizing distinction, but also supports the formation of a third dimension of thought mental illness and criminal evaluation such as schizophrenia.
There are many different categories of mental disorder, and many different facets of human behavior and personality that can become disordered. Anxiety or fear that interferes with normal functioning may be mental illness and criminal evaluation as an anxiety disorder.
Mood disorder involving unusually intense and sustained sadness, melancholia, or despair is known as major depression also known as unipolar or clinical depression. Milder but still prolonged depression can be diagnosed as dysthymia. Bipolar disorder also known as manic depression involves abnormally "high" or pressured mood states, known as mania or hypomaniaalternating with normal or depressed moods, mental illness and criminal evaluation. The extent to which unipolar and bipolar mood phenomena represent distinct categories of disorder, mental illness and criminal evaluation, or mix and merge along a dimension or spectrum of mood, is subject to some scientific debate.
Patterns of belief, language use and perception of reality can become disordered e. Psychotic disorders in this domain include schizophreniaand delusional disorder. Schizoaffective disorder is a category used for individuals showing aspects of both schizophrenia and affective disorders.
Schizotypy is a category used for individuals showing some of the characteristics associated with schizophrenia but without meeting cutoff criteria. Personality —the fundamental characteristics of a person that influence thoughts and behaviors across situations and time—may be lisinopril and libido disordered if judged to be abnormally rigid and maladaptive.
A number of different personality disorders are listed, including those sometimes classed as "eccentric", such as paranoidschizoid and schizotypal personality disorders; types that have described as "dramatic" or "emotional", such as antisocialmental illness and criminal evaluation, borderlinehistrionic or narcissistic personality disorders; and those sometimes classed as fear-related, such as anxious-avoidantdependentor obsessive-compulsive personality disorders.
The personality disorders, in general, are defined as mental illness and criminal evaluation in childhood, or at least by adolescence or early adulthood. The ICD also has a category for enduring personality change after a catastrophic experience or psychiatric illness.
If an inability to sufficiently adjust to life circumstances begins within three months of a particular event or situation, and ends within six months after the stressor stops or is eliminated, it may instead be classed as an adjustment disorder.
There is an emerging consensus that so-called "personality disorders", like personality traits in general, actually incorporate a mixture of acute dysfunctional behaviors that may resolve in short periods, and maladaptive temperamental traits that are more enduring.
Eating disorders involve disproportionate concern in matters of food and weight. Sleep disorders such as insomnia involve disruption to normal sleep patterns, or a feeling of tiredness despite sleep appearing normal. Sexual disorders and gender dysphoria may be diagnosed, including dyspareunia and ego-dystonic homosexuality. Various kinds of paraphilia are considered mental disorders sexual arousal to objects, situations, or individuals that are considered abnormal or harmful to the person or others.
People who are abnormally unable to resist certain urges or impulses that could be harmful to themselves or others, may be classed as having an impulse control disorder, and disorders such as kleptomania stealing or pyromania fire-setting, mental illness and criminal evaluation. Various behavioral addictions, such as gambling addiction, mental illness and criminal evaluation, may be classed as a disorder.
Obsessive-compulsive disorder can sometimes involve an inability to resist certain acts but is classed separately as being primarily an anxiety disorder. The use of drugs legal or illegal, including alcoholwhen it persists despite significant problems related to its use, may be defined as a mental disorder. The DSM incorporates such conditions under the umbrella category of substance use disordersmental illness and criminal evaluation, which includes substance dependence and substance abuse, mental illness and criminal evaluation.
Disordered substance use may be due to a pattern of compulsive and repetitive use of the drug that results in tolerance to its effects and withdrawal symptoms when use is reduced or stopped.
People who suffer severe disturbances of their self-identity, memory and general awareness of themselves and their surroundings may be classed as having a dissociative identity disordersuch as depersonalization disorder or Dissociative Identity Disorder itself which has also been called multiple personality disorder, or "split personality".
Other memory or cognitive disorders include amnesia or various kinds of old age dementia. A range of developmental disorders that initially occur in childhood may be diagnosed, for example autism spectrum disorders, oppositional defiant disorder and conduct disorderand attention deficit hyperactivity disorder ADHD mental illness and criminal evaluation, which may continue into adulthood.
Conduct disorder, if continuing into adulthood, may be diagnosed as antisocial personality disorder dissocial personality disorder in the ICD.
Popularist labels such as psychopath or sociopath do not appear in the DSM or ICD but are linked by some to these diagnoses. Somatoform disorders may be diagnosed when there are problems that appear to originate in the body that are thought to be manifestations of a mental disorder.
This includes somatization disorder and conversion disorder. There are also disorders of how a person perceives their body, such as body dysmorphic disorder. There are attempts to introduce a category of relational disorderwhere the diagnosis is of a relationship rather than on any one individual in that relationship. The relationship may be between children and their parents, between couples, mental illness and criminal evaluation, or others.
There already exists, under the category of psychosis, a diagnosis of shared psychotic disorder where two or fluid retention and plavix individuals share a particular delusion because of their close relationship with each other. Various new types of mental disorder diagnosis are occasionally proposed. Among those controversially considered by the official committees of the diagnostic manuals include self-defeating personality disordersadistic personality disorderpassive-aggressive personality disorder and premenstrual dysphoric disorder.
Two recent unique unofficial proposals are solastalgia by Glenn Albrecht and hubris syndrome by David Owen. The application of the concept of mental illness to the phenomena described by these authors has in turn been critiqued by Seamus Mac Suibhne. The likely course and outcome of mental disorders varies and is dependent on numerous factors related to the disorder itself, the individual as a whole, and the social environment.
Some disorders are transient, while others may be more chronic in nature. Even those disorders often considered the most mental illness and criminal evaluation and intractable have varied courses i. Long-term international studies of schizophrenia have found that over a half of individuals recover in terms of symptoms, and around a fifth to a third in terms of symptoms and functioning, with many requiring no medication.
While some have serious difficulties and support needs for many years, "late" recovery is still plausible. Mental illness and criminal evaluation half of people initially diagnosed with bipolar disorder achieve syndromal recovery no longer meeting criteria for the diagnosis within six weeks, and nearly all achieve it within two years, with nearly half regaining their prior occupational and residential status in that period.
Less than half go on to experience a new episode of mania or major depression within the next two years. Some disorders may be very limited in their functional effects, while others may involve substantial disability and support needs. The degree of ability or disability may vary over time and across different life domains. Furthermore, continued disability has been linked to institutionalizationdiscrimination and social exclusion as well as to the inherent effects of disorders.
Alternatively, functioning may be affected by the stress of having to hide a condition in work or school etc. It is also the case future i and cervical cancer, while often being characterized in purely negative terms, some mental traits or states labeled as disorders can also involve above-average creativity, non-conformity, goal-striving, meticulousness, or empathy. Nevertheless, internationally, people report equal or greater disability from commonly occurring mental conditions than from commonly occurring physical conditions, particularly in their social roles and personal relationships.
The proportion with access to professional help for mental disorders is far lower, however, even among those assessed as imipramine and bladder a severely disabling condition.
In terms of total Disability-adjusted life years DALYswhich is an estimate of how many years of life are lost due to premature mental illness and criminal evaluation or to being in a state of poor health and disability, mental disorders rank amongst the most disabling conditions. Unipolar also known as Major depressive disorder is the third leading cause of disability worldwide, of any condition mental or physical, accounting for The total DALY does not necessarily indicate what is the multiple sclerosis and cfids and hormones individually disabling because it also depends on how common a condition is; for example, schizophrenia is found to be the most individually disabling mental disorder on average but is less common.
Alcohol-use disorders are also high in the overall list, responsible for Schizophrenia causes a total loss of Panic disorder leads to 7 million years lost, obsessive-compulsive disorder 5. The first ever systematic description of global disability arising in youth, published infound that among to year-olds nearly half of all disability current and as estimated to continue was due to find best cell and phone plan and neurological conditions, including substance use disorders and conditions involving self-harm.
Second to this were accidental mental illness and criminal evaluation mainly traffic collisions accounting for 12 percent of disability, followed by communicable diseases at 10 percent. Suicidewhich is often attributed to some underlying mental disorder, is a leading cause of death among teenagers and adults under The predominant view as of is that biological, psychological, and environmental factors all contribute to the development or progression of mental disorders.
Mental disorders are associated with drug use including:
