What is neurosis in psychology?
Neurosis, a term that is generally outmoded in modern psychology, refers to mental disorders characterized by distress, anxiety, or depression. Neuroses can impair a person’s ability to function in areas of life such as work and relationships, but not to the point of incapacitation.
Psychoanalytic theory suggests that neuroses arise from conflict between drives, impulses, and motives within the mind. Sigmund Freud believed that repressed, unacceptable thoughts and feelings are stored in the unconscious mind, causing anxiety. The mind then uses defense mechanisms to keep these thoughts from becoming conscious.
Examples of conditions once labeled as neuroses include obsessive-compulsive disorders, somatoform disorder (also known as somatic symptom disorder), anxiety disorders, and depression.

How do people with neurosis usually feel or act?
The terms neurosis and psychoneurosis are generally outmoded terms that lack the precision required for psychological diagnosis and are no longer used for that purpose. Neuroses were associated with feelings of unhappiness or distress, such as anxiety and depression, that threatened to impair a person’s ability to function in work and relationships; however, they were not severe enough to be incapacitating, and a connection to reality was maintained.
Various conditions have been described as types of neuroses, such as anxiety disorders, obsessive-compulsive disorders, somatoform disorders (also known as somatic symptom disorder), depression, and post-traumatic stress disorder.

What are some common types of neuroses?
The term neurosis is generally outmoded and lacks the precision required for psychological diagnosis, so it is no longer used for that purpose. It was used to refer to mental disorders characterized by unhappiness, anxiety, or distress that threatened to impair a person’s ability to function in work and relationships, but not severely enough to be incapacitating.
Examples of conditions that had been described as types of neuroses include:
* Anxiety disorders were frequently described as neuroses, with anxiety as the principal feature. Types of anxiety disorders include phobias, panic disorder, and generalized anxiety disorder.
* Obsessive-compulsive disorders are characterized by intrusive, anxiety-provoking thoughts or images (obsessions) that lead to repetitive, ritualized thoughts or acts (compulsions) to reduce the anxiety.
* Somatoform disorders (also known as somatic symptom disorders) were also once labeled as a neurosis. This condition is characterized by the manifestation of maladaptive behaviors as physical symptoms, such as blindness or paralysis, that occur in the absence of any obvious cause.
* Post-traumatic stress disorder is a syndrome that can affect individuals who have endured a highly traumatic event. Symptoms include nightmares, anxiety, and guilt.
* Depression, when neither excessively severe nor prolonged, was also regarded as a neurosis.4 Britannica SourcesCreated from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles. -
How does neurosis differ from psychosis?
Psychosis and neurosis are both mental illnesses, but psychosis is more severe. Psychosis can cause hallucinations (sensory perceptions not shared by others), delusions (beliefs not credible to others), and defects in judgment. A person experiencing psychosis may not be able to take care of themselves and may require hospitalization.
Neurosis, on the other hand, is a less-severe mental disorder. The symptoms of neurosis can be disabling, but a person experiencing neurosis has a sense of reality and a personality that sets them apart from psychotics. Types of neuroses include anxiety disorders, obsessive-compulsive disorders, and depression.

What are possible causes of neurosis?
The term neurosis is generally outmoded and refers to mental disorders characterized by distress, anxiety, or depression. The causes of mental disorders, including what was once called neurosis, are complex and can involve a combination of factors.
Possible causes:
* Genetic predisposition Research indicates that genetics may play a role in the development of certain mood and anxiety disorders. Studies show that individual differences in neuroticism are substantially heritable.
* Biochemical imbalances Mental disorders may stem from biochemical imbalances in the brain.
* Intrapsychic conflict Conflicting motives, drives, and feelings within the mind may cause neurotic symptoms.
* Faulty learning processes Behavioral theories suggest that neurotic symptoms, like phobias, can be learned behaviors resulting from conditioning.
* Stressful life events Stressful events can trigger the onset of mental disorders.
* Childhood experiences Traumatic events, deprivations, and frustrations during childhood can lead to unresolved conflicts that influence personality development and increase the likelihood of neurosis.5 Britannica SourcesCreated from Britannica articles using AI.

How can neurosis be treated or managed?
Several therapeutic approaches can treat or manage neurosis, including psychoanalytic, cognitive, and interpersonal approaches. Psychoanalytic therapy helps patients understand repressed memories and feelings. Cognitive and interpersonal approaches address thoughts and perceptions contributing to "neurotic" symptoms, replacing them with realistic interpretations.
Cognitive behavior therapy (CBT) is a common psychotherapy that helps people change inaccurate or negative thinking patterns, manage emotions, and deal effectively with stress. CBT techniques include cognitive restructuring, behavioral experiments, exposure, relaxation-based strategies, and social and communication skills training.
Additionally, psychiatrists may use psychotropic drugs, but the exact treatment depends on the patient’s condition.

neurosis, generally outmoded term used to refer to mental disorders characterized by anxiety, depression, or other feelings of unhappiness or distress. Neuroses typically were associated with a sense of distress and a deficit in functioning to the extent that they threatened to impair a person’s ability to function in virtually any area of life, including work and relationships. However, they generally were not severe enough to be incapacitating, and a connection to reality was maintained (in contrast to persons with psychoses, who experience some loss in their contact with reality).
Psychiatrists first used the term neurosis in the mid-19th century to categorize symptoms thought to be neurological in origin; the prefix psycho- was added some decades later when it became clear that mental and emotional factors were important in the etiology of those disorders. The terms neurosis and psychoneurosis later were used interchangeably, although the shorter version was more common. Both terms, however, lack the precision required for psychological diagnosis and are no longer used for that purpose.
Theories
An influential view held by the psychoanalytic tradition was that neuroses arise from intrapsychic conflict (conflict between different drives, impulses, and motives held within various components of the mind). Central to psychoanalytic theory, which was founded by Austrian neurologist Sigmund Freud, is the postulated existence of an unconscious part of the mind which, among other functions, acts as a repository for repressed thoughts, feelings, and memories that are disturbing or otherwise unacceptable to the conscious mind. These repressed mental contents are typically sexual or aggressive urges or painful memories of an emotional loss or an unsatisfied longing dating from childhood.
Anxiety arises when unacceptable and repressed drives threaten to enter consciousness; prompted by anxiety, the conscious part of the mind (the ego) tries to deflect the emergence into consciousness of the repressed mental contents through the use of defense mechanisms, such as repression, denial, or reaction formation. Neurotic symptoms were thought to emerge when a previously impermeable defense mechanism broke down and a forbidden drive or impulse threatened to enter consciousness. See also psychoanalysis.
While the psychoanalytic theory remained influential, another prominent view, associated with behavioral psychology, represented neurosis as a learned, inappropriate response to stress that can be unlearned. A third view, stemming from cognitive theory, emphasized the way in which maladaptive thinking—such as the fear of possible punishment—promotes an inaccurate perception of the self and surrounding events.
Types
Various conditions had been described as types of neuroses, though their descriptions as such are obsolete. Examples of such conditions include obsessive-compulsive disorders, which are characterized by the irresistible entry of unwanted ideas, thoughts, or feelings into consciousness or by the need to repeatedly perform ritualistic actions that the person performing the actions perceives as unnecessary or unwarranted. Obsessive ideas may include recurrent violent or obscene thoughts; compulsive behavior includes rituals such as repetitive hand washing or door locking, which are carried out in response to an obsession. The tricyclic antidepressant drug clomipramine and the selective serotonin reuptake inhibitor (SSRI) fluoxetine (Prozac) have been effective in treating many patients with obsessive-compulsive disorders.
Somatoform disorder (also known as somatic symptom disorder) was also once labeled as a neurosis. This condition is characterized by the manifestation of maladaptive behaviors as physical symptoms, such as blindness, paralysis, or deafness; physical symptoms typically occur in the absence of any obvious cause, including organic disease. Hysteria, later more commonly referred to as conversion disorder, was among the earliest syndromes to be treated by psychoanalysts, who thought that such symptoms result from fixations or arrested stages in an individual’s early psychosexual development.
Anxiety disorders were also frequently described as neuroses, with anxiety being the principal feature. Anxiety manifests itself either in relatively short, acute anxiety attacks or in a chronic sense of nameless dread. Persons undergoing anxiety attacks may experience digestive symptoms, excessive perspiration, headaches, heart palpitations, restlessness, insomnia, disturbances in appetite, and impaired concentration. Phobia, a type of anxiety disorder, is represented by inappropriate fears that are triggered by specific situations or objects. Some common objects of phobias are open or closed spaces, fire, high places, dirt, and bacteria.
Depression, when neither excessively severe nor prolonged, was also regarded as a neurosis. Depression often is associated with feelings of sadness and hopelessness as well as with pessimism, listlessness, fatigue, delays in thought and action, reduced appetite, and difficulty sleeping. Likewise, post-traumatic stress disorder, a syndrome that can affect individuals who have endured some highly traumatic event, such as a natural disaster, torture, or incarceration in a concentration camp, was considered a type of neurosis. The symptoms include nightmares, a diffuse anxiety, and guilt over having survived when others perished.
Treatment
Psychiatrists and psychologists treated neuroses in a variety of ways. The psychoanalytic approach involved helping patients to become aware of repressed impulses, feelings, and traumatic memories underlying their symptoms, thereby enabling them to achieve deeper self-understanding. In some instances, treatment centered on reconditioning a patient through a process known as desensitization; someone afraid of heights, for example, would be gradually exposed to progressively greater heights over several weeks.
Other learning approaches included modeling more effective behavior, wherein the patient learns by example. Cognitive and interpersonal approaches included discussing thoughts and perceptions that contributed to a patient’s “neurotic” symptoms, eventually replacing them with more realistic interpretations of external events and the patient’s internal responses to them. Many psychiatrists preferred physical approaches, such as psychotropic drugs (including antianxiety agents, antidepressants, and antipsychotic drugs) and electroconvulsive (shock) therapy. Many psychiatrists advocated combinations of these approaches, the exact nature of which depended on the patient’s condition.
Although many such approaches, including various forms of psychotherapy, remain common in the treatment of anxiety, depression, and other mental disorders, some have been supplanted by more-modern therapeutic strategies. Examples of newer treatment approaches that may be used include dialectical behavior therapy, transcranial magnetic stimulation, and eye movement and desensitization reprocessing therapy.
