Personality disorderPersonality disorders (PD) are a class of mental disorders characterized by enduring maladaptive patterns of behavior, cognition, and inner experience, exhibited across many contexts and deviating from those accepted by the individual's 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.
Dementia praecoxDementia praecox (meaning a "premature dementia" or "precocious madness") is a disused psychiatric diagnosis that originally designated a chronic, deteriorating psychotic disorder characterized by rapid cognitive disintegration, usually beginning in the late teens or early adulthood. Over the years, the term dementia praecox was gradually replaced by the term schizophrenia, which initially had a meaning that included what is today considered the autism spectrum. The term dementia praecox was first used by German psychiatrist Heinrich Schüle in 1880.
Id, ego and super-egoIn psychoanalytic theory, the id, ego and super-ego are three distinct, interacting agents in the psychic apparatus, defined in Sigmund Freud's structural model of the psyche. The three agents are theoretical constructs that Freud employed to describe the basic structure of mental life as it was encountered in psychoanalytic practice. Freud himself used the German terms das Es, Ich, and Über-Ich, which literally translate as "the it", "I", and "over-I". The Latin terms id, ego and super-ego were chosen by his original translators and have remained in use.
Dissociation (psychology)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 loss of reality as in psychosis. The phenomena are diagnosable under the DSM-5 as a group of disorders as well as a symptom of other disorders through various diagnostic tools.
Defence mechanismIn psychoanalytic theory, a defence mechanism (American English: defense mechanism) is an unconscious psychological operation that functions to protect a person from anxiety-producing thoughts and feelings related to internal conflicts and outer stressors. Defence mechanisms (Abwehrmechanismen) are unconscious psychological processes employed to defend against feelings of anxiety and unacceptable impulses at the level of consciousness.
Dissociative identity disorderDissociative identity disorder (DID), formerly known as multiple personality disorder, split personality disorder or dissociative personality disorder, is a member of the family of dissociative disorders classified by the DSM-5, DSM-5-TR, ICD-10, ICD-11, and Merck Manual for diagnosis. It remains a controversial diagnosis, despite rigorous study in the scientific literature since 1975. Dissociative identity disorder is characterized by the presence of at least two distinct and relatively enduring personality states.
Schizoid personality disorderSchizoid personality disorder (ˈskɪtsɔɪd,_ˈskɪdzɔɪd,_ˈskɪzɔɪd, often abbreviated as SzPD or ScPD) is a personality disorder characterized by a lack of interest in social relationships, a tendency toward a solitary or sheltered lifestyle, secretiveness, emotional coldness, detachment, and apathy. Affected individuals may be unable to form intimate attachments to others and simultaneously possess a rich and elaborate but exclusively internal fantasy world.
Sigmund FreudSigmund Freud (frɔɪd , ˈziːkmʊnt ˈfʁɔʏt; born Sigismund Schlomo Freud; 6 May 1856 – 23 September 1939) was an Austrian neurologist and the founder of psychoanalysis, a clinical method for evaluating and treating pathologies seen as originating from conflicts in the psyche, through dialogue between patient and psychoanalyst, and the distinctive theory of mind and human agency derived from it. Freud was born to Galician Jewish parents in the Moravian town of Freiberg, in the Austrian Empire.
Borderline personality disorderBorderline personality disorder (BPD), also known as emotionally unstable personality disorder (EUPD), is a personality disorder characterized by a long-term pattern of intense and unstable interpersonal relationships, distorted sense of self, and strong emotional reactions. Those affected often engage in self-harm and other dangerous behaviors, often due to their difficulty with returning their emotional level to a healthy or normal baseline. They may also struggle with a feeling of emptiness, fear of abandonment, and dissociation.
Narcissistic personality disorderNarcissistic personality disorder (NPD) is a personality disorder that involves self-loathing, a fragile self-esteem and compensatory self-importance. It is also associated with primitive defence mechanisms and a superiority complex that protect the individual psychologically. The conduct of one's life is often disingenuous in the patient population and the avoidance of the appearance of inferiority (dependence) is common. Research has pointed that agreeableness is exceedingly low translating to lack of empathy and altruism.
Sublimation (psychology)In psychology, sublimation is a mature type of defense mechanism, in which socially unacceptable impulses or idealizations are transformed into socially acceptable actions or behavior, possibly resulting in a long-term conversion of the initial impulse. Sigmund Freud believed that sublimation was a sign of maturity and civilization, allowing people to function normally in culturally acceptable ways.
NeuroticismIn the study of psychology, neuroticism has been considered a fundamental personality trait. In the Big Five approach to personality trait theory, individuals with high scores for neuroticism are more likely than average to be moody and to experience such feelings as anxiety, worry, fear, anger, frustration, envy, jealousy, pessimism, guilt, depressed mood, and loneliness. Such people are thought to respond worse to stressors and are more likely to interpret ordinary situations, such as minor frustrations, as appearing hopelessly difficult.
Psychological traumaPsychological trauma (mental trauma, psychotrauma, or psychiatric trauma) is an emotional response caused by severe distressing events such as accidents, violence, sexual assault, terror, or sensory overload. Short-term reactions such as psychological shock and psychological denial are typically followed. Long-term reactions and effects include bipolar disorder, uncontrollable flashbacks, panic attacks, insomnia, nightmare disorder, difficulties with interpersonal relationships, and post-traumatic stress disorder (PTSD).
Perfectionism (psychology)Perfectionism, in psychology, is a broad personality trait characterized by a person's concern with striving for flawlessness and perfection and is accompanied by critical self-evaluations and concerns regarding others' evaluations. It is best conceptualized as a multidimensional and multilayered personality characteristic, and initially some psychologists thought that there were many positive and negative aspects.
Psychoanalytic theoryPsychoanalytic theory is the theory of personality organization and the dynamics of personality development relating to the practice of psychoanalysis, a clinical method for treating psychopathology. First laid out by Sigmund Freud in the late 19th century, psychoanalytic theory has undergone many refinements since his work. The psychoanalytic theory came to full prominence in the last third of the twentieth century as part of the flow of critical discourse regarding psychological treatments after the 1960s, long after Freud's death in 1939.
Repression (psychoanalysis)Repression is a key concept of psychoanalysis, where it is understood as a defense mechanism that "ensures that what is unacceptable to the conscious mind, and would if recalled arouse anxiety, is prevented from entering into it." According to psychoanalytic theory, repression plays a major role in many mental illnesses, and in the psyche of the average person. American psychologists began to attempt to study repression in the experimental laboratory around 1930.
Individual psychologyIndividual psychology (Individualpsychologie) is a psychological method or science founded by the Viennese psychiatrist Alfred Adler. The English edition of Adler's work on the subject (1925) is a collection of papers and lectures given mainly between 1912 and 1914. The papers cover the whole range of human psychology in a single survey, and were intended to mirror the indivisible unity of the personality. In developing the concept of individual psychology, Adler broke away from the psychoanalytic school of Sigmund Freud.
Rational emotive behavior therapyRational emotive behavior therapy (REBT), previously called rational therapy and rational emotive therapy, is an active-directive, philosophically and empirically based psychotherapy, the aim of which is to resolve emotional and behavioral problems and disturbances and to help people to lead happier and more fulfilling lives. REBT posits that people have erroneous beliefs about situations they are involved in, and that these beliefs cause disturbance, but can be disputed and changed.
Histrionic personality disorderHistrionic personality disorder (HPD) is defined by the American Psychiatric Association as a personality disorder characterized by a pattern of excessive attention-seeking behaviors, usually beginning in early adulthood, including inappropriate seduction and an excessive desire for approval. People diagnosed with the disorder are said to be lively, dramatic, vivacious, enthusiastic, extroverted and flirtatious. HPD lies in the dramatic cluster of personality disorders.
Conversion disorderConversion disorder (CD), or functional neurologic symptom disorder, is a diagnostic category used in some psychiatric classification systems. It is sometimes applied to patients who present with neurological symptoms, such as numbness, blindness, paralysis, or fits, which are not consistent with a well-established organic cause, which cause significant distress, and can be traced back to a psychological trigger. It is thought that these symptoms arise in response to stressful situations affecting a patient's mental health or an ongoing mental health condition such as depression.
