Borderline personality disorder (BPD) is a personality disorder characterized by a pervasive, long-term pattern of significant interpersonal relationship instability, a distorted sense of self, and intense emotional responses. People diagnosed with BPD frequently exhibit self-harming behaviours and engage in risky activities, primarily due to challenges regulating emotional states to a healthy, stable baseline. Symptoms such as dissociation, a pervasive sense of emptiness, and an acute fear of abandonment are prevalent among those affected.
Substance intoxication is a transient condition of altered consciousness and behavior associated with recent use of a substance. It is often maladaptive and impairing, but reversible. If the symptoms are severe, the term "substance intoxication delirium" may be used. Slang terms for the state include: getting high (generic), and being stoned, cooked, or fried.
Antisocial personality disorder (ASPD) is a personality disorder defined by a chronic pattern of behavior that disregards the rights and well-being of others. People with ASPD often exhibit behavior that conflicts with social norms, leading to issues with interpersonal relationships, employment, and legal matters. The condition generally manifests in childhood or early adolescence, with a high rate of associated conduct problems and a tendency for symptoms to peak in late adolescence and early adulthood.
Hypersexuality is a medical condition that causes unwanted or excessive sexual arousal, causing people to engage in or think about sexual activity to a point of distress or impairment. It is controversial whether it should be included as a clinical diagnosis used by mental healthcare professionals. Nymphomaniac and sex maniac were terms previously used for the condition in women and men, respectively.
Individuals who experience depersonalization feel divorced from their own personal self as not belonging to the same identity.]] Depersonalization is a dissociative phenomenon characterized by a subjective feeling of detachment from oneself, manifesting as a sense of disconnection from one's thoughts, emotions, sensations, or actions, and often accompanied by a feeling of observing oneself from an external perspective. Subjects perceive that the world has become vague, dreamlike, surreal, or strange, leading to a diminished sense of individuality or identity. Sufferers often feel as though they are observing the world from a distance, as if separated by a barrier "behind glass". They maintain insight into the subjective nature of their experience, recognizing that it pertains to their own perception rather than altering objective reality. This distinction between subjective experience and objective reality distinguishes depersonalization from delusions, where individuals firmly believe in false perceptions as genuine truths. Depersonalization is also distinct from derealization, which involves a sense of detachment from the external world rather than from oneself.
Kleptomania is the inability to resist the urge to steal items, usually for reasons other than personal use or financial gain. First described in 1816, kleptomania is classified in psychiatry as an impulse control disorder. Some of the main characteristics of the disorder suggest that kleptomania could be an obsessive-compulsive spectrum disorder, but also share similarities with addictive and mood disorders.
Dialectical behavior therapy (DBT) is an evidence-based psychotherapy that began with efforts to treat personality disorders and interpersonal conflicts. Evidence suggests that DBT can be useful in treating mood disorders and suicidal ideation as well as for changing behavioral patterns such as self-harm and substance use. DBT evolved into a process in which the therapist and client work with acceptance and change-oriented strategies and ultimately balance and synthesize them—comparable to the philosophical dialectical process of thesis and antithesis, followed by synthesis.
Dissociation is a concept that has been developed over time and which concerns a wide array of experiences, ranging from a mild emotional detachment from the immediate surroundings, to a more severe disconnection from physical and emotional experiences. The major characteristic of all dissociative phenomena involves a detachment from reality, rather than a false perception of reality as in psychosis.
Daydreaming is a stream of consciousness that detaches from current external tasks when one's attention becomes focused on a more personal and internal direction.
Psychopathology is the study of mental illness. It includes the signs and symptoms of all mental disorders. The field includes abnormal cognition, maladaptive behavior, and experiences which differ according to social norms. This discipline is an in-depth look into symptoms, behaviors, causes, course, development, categorization, treatments, strategies, and more.
Depersonalization-derealization disorder is a mental disorder in which the person has persistent or recurrent feelings of depersonalization and/or derealization. Depersonalization is described as feeling disconnected or detached from one's self. Individuals may report feeling as if they are an outside observer of their own thoughts or body, and often report feeling a loss of control over their thoughts or actions. Derealization is described as detachment from one's surroundings. Individuals experiencing derealization may report perceiving the world around them as foggy, dreamlike, surreal, and/or visually distorted.
Dissociative disorders (DDs) are a range of conditions characterized by significant disruptions or fragmentation "in the normal integration of consciousness, memory, identity, emotion, perception, body representation, motor control, and behavior." Dissociative disorders involve involuntary dissociation as an unconscious defense mechanism, wherein the individual with a dissociative disorder experiences separation in these areas as a means to protect against traumatic stress. Some dissociative disorders are caused by major psychological trauma, though the onset of depersonalization-derealization disorder may be preceded by less severe stress, by the influence of psychoactive substances, or occur without any discernible trigger.
In psychology, emotional detachment, also known as emotional blunting, is a condition or state in which a person lacks emotional connectivity to others, whether due to an unwanted circumstance or as a positive means to cope with anxiety. Such a coping strategy, also known as emotion-focused coping, is used when avoiding certain situations that might trigger anxiety. It refers to the evasion of emotional connections. Emotional detachment may be a temporary reaction to a stressful situation, or a chronic condition such as depersonalization-derealization disorder. It may also be caused by certain antidepressants. Emotional blunting, also known as reduced affect display, is one of the negative symptoms of schizophrenia.
Absent-mindedness is a mental state wherein a person is forgetfully inattentive. It is the opposite mental state of mindfulness.
Internet addiction "disorder" (IAD), also known as problematic internet use, or pathological internet use, is a problematic compulsive use of the internet, particularly on social media, that impairs an individual's function over a prolonged period of time. Young people are at particular risk of developing internet addiction disorder, with case studies highlighting students whose academic performance declines as they spend more time online. Some experience health consequences from loss of sleep as they stay up to continue scrolling, chatting, and gaming.
Derealization is an alteration in the perception of the external world, causing those with the condition to perceive it as unreal, distant, distorted or in other words falsified. Other symptoms include feeling as if one's environment is lacking in spontaneity, emotional coloring, and depth. Described as "Experiences of unreality or detachment with respect to surroundings in the DSM-5, it is a dissociative symptom that may appear in moments of severe stress.
Personality disorders (PD) are a class of mental health conditions characterized by enduring maladaptive patterns of behavior, cognition, and inner experience, exhibited across many contexts and deviating from those accepted by the culture. These patterns develop early, are inflexible, and are associated with significant distress or disability. The definitions vary by source and remain a matter of controversy. Official criteria for diagnosing personality disorders are listed in the sixth chapter of the International Classification of Diseases (ICD) and in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM).
Fantasy-prone personality (FPP) is a disposition or personality trait in which a person experiences a lifelong, extensive, and deep involvement in fantasy. This disposition is an attempt, at least in part, to better describe "overactive imagination" or "living in a dream world". An individual with this trait may have difficulty differentiating between fantasy and reality and may experience hallucinations, as well as self-suggested psychosomatic symptoms. Closely related psychological constructs include daydreaming, absorption and eidetic memory.
Compulsive sexual behaviour disorder (CSBD), is an impulse control disorder. CSBD manifests as a pattern of behavior involving intense preoccupation with sexual fantasies and behaviours that cause significant levels of psychological distress, are inappropriately used to cope with psychological stress, cannot be voluntarily curtailed, and risk or cause harm to oneself or others. This disorder can also cause impairment in social, occupational, personal, or other important functions. CSBD is not an addiction, and is typically used to describe behavior, rather than "sexual addiction".
Absorption is a disposition or personality trait in which a person becomes absorbed in their mental imagery, particularly fantasy. This trait thus correlates highly with a fantasy prone personality. The original research on absorption was by Dutch American psychologist Auke Tellegen. The construct of absorption was developed in order to relate individual differences in hypnotisability to broader aspects of personality. Absorption has a variable correlation with hypnotisability (r = 0.13–0.89) perhaps because in addition to broad personality dispositions, situational factors play an important role in performance on tests of hypnotic susceptibility. Absorption is one of the traits assessed in the Multidimensional Personality Questionnaire.
