• In anger / Prompted by rage — A Latin phrase translated as 'by an angry person' or 'under the impulse of rage'. In psychopathology, clinical psychology, and forensic psychiatry, it describes acts, statements, or assaults committed during an intense affective state, where extreme rage temporarily narrows the field of consciousness and reduces the patient's capacity to control impulses or evaluate consequences.
• Abasic — A medical term describing a person affected by abasia, characterized by the partial or total inability to walk or maintain an erect posture, despite muscular strength, sensation, and coordination of the limbs being completely preserved in the recumbent position. It is encountered in organic neurological conditions (frontal or cerebellar lesions, extrapyramidal syndromes) or in psychogenic conversion disorders (classical hysteria, presenting as astasia-abasia syndrome).
• Abasic (feminine) — The feminine form of the adjective abasic, used to describe a female patient, a disorder, or a clinical manifestation (such as a posture or a gait disturbance) characterized by the inability to walk, despite the preservation of muscle strength in the recumbent position. In medical literature, it is frequently used to qualify the psychogenic or organic nature of a motor dysfunction specific to female patients or an anatomical element.
• Abasia — A neurological and neuropsychiatric symptom characterized by the total or partial inability to walk, whereas muscular strength, coordination of movements in the recumbent position, and sensation in the legs remain completely intact. It can have an organic cause, linked to lesions of the frontal lobe, cerebellum, or vestibular pathways, or a functional (psychogenic) cause, encountered within conversion (dissociative) disorders, where it is frequently associated with astasia (the inability to stand).
• To form an abscess / To abscess — A pathological process where a localized acute purulent inflammation or bacterial infection evolves into a distinct abscess, accumulating pus and causing necrosis of the surrounding tissues.
• Abscessation / Abscess formation — The pathological process of abscess formation; the transformation of an acute inflammation or diffuse inflammatory infiltrate (such as cellulitis or phlegmon) into a well-circumscribed purulent collection, accompanied by liquefactive tissue necrosis.
• Abscessation / Process of abscessing — The action or process of forming an abscess; the nominalized form describing the transition of an inflammatory cell infiltrate into a circumscribed purulent collection.
• Abdominalgia — A clinical term used to describe any form of pain localized within the abdomen. In psychiatric semiology and psychosomatic medicine, abdominalgia represents one of the most common somatic complaints, often being the clinical expression of a conversion disorder, generalized anxiety, or a masked depressive episode, where organic investigations reveal no structural lesion.
• Abebe phenomenon — An eponym used in transcultural psychiatry, ethnopsychiatry, and clinical anthropology studies to illustrate trance phenomena, possession, or dissociative disorders specific to the Horn of Africa (the Abebe manifestation or syndrome). The term analyzes how severe psychic conflicts, collective traumas, or acute stress are culturally shaped into dissociative convulsive seizures, structured mystic hallucinations, or altered states of personality integrated into local medical folklore.
• Abeceda (archaic alphabet) — An archaic regional variant for 'abecedar' (primer) or 'alfabet' (alphabet), historically used in Transylvania and Banat, stemming from Slavic and Hungarian roots. In clinical psycholinguistics and speech therapy, the term is studied within primary literacy assessment tests to identify early signs of developmental dyslexia, agraphia, or during language re-education in aphasic patients who suffered stroke injuries in cortical language areas (Broca and Wernicke).
• Abelard complex — A cultural and clinical eponym derived from the medieval philosopher Peter Abelard, used in the history of psychiatry, psychoanalysis, and sexology (the Abelard complex or syndrome). The term denotes a specific type of neuro-psychic structure or castration complex, characterized by the forced sublimation of sexual impulses into rigid intellectual or mystic achievements following severe somatic or psychic trauma. It also analyzes the dynamics of obsessive interdependence in couples with symmetrical intellectual fixations.
• Abeona developmental archetype — A mythological and cultural eponym transposed into developmental psychology and pediatric psychoanalysis (the Abeona complex, syndrome, or archetype). The concept denotes the protective maternal instinct of guiding and facilitating a child's first independent steps outside the secure family space. In the semiology of attachment, pathological manifestations of the Abeona type refer to severe parental separation anxiety (neurotic overprotection) that blocks the infant's motor and cognitive autonomy development.
• Act of aberrating — The act of aberrating; the process of moving away, wandering, or deviating from a straight line, a scientific truth, a logical rule, or a moral norm. Figuratively and in daily language, it represents uttering absurd statements devoid of logic or real basis. In an old technical sense, it indicated the temporary wandering of a flow or trajectory from its initial coordinates.
• Abkhazia — A geographical region located on the eastern coast of the Black Sea and the southern slope of the Greater Caucasus. In the field of balneoclimatology and Eastern European medical history, Abkhazia is internationally recognized as a premier therapeutic climatic zone, famous for its sanatoriums in Gagra or Sukhumi, built for the recovery of patients with chronic respiratory ailments, pulmonary tuberculosis, and cardiovascular diseases due to ionized mountain-marine air.
• Abhorrence / Loathing act — The act of abhorring and its result; the psychic process or external manifestation of a deep feeling of rejection, ultimate detestation, hatred, or unyielding aversion. In medical terminology and behavioral analysis, the term indicates the psychic dynamics through which an individual expresses somatic or ideational repulsion, serving as an important indicator in evaluating the intensity of affective disorders or conditioned aversions.
• Abiotrophic — A quality referring to abiotrophy; characterized by a gradual loss of vitality, progressive degeneration, or an inability for normal nutrition and development of certain cells, tissues, or organs, caused by intrinsic or genetic factors, in the absence of an obvious external cause.
• Abiotrophy — A biological phenomenon or state characterized by the gradual loss of vitality, diminution of physiological resistance, and progressive degeneration of certain cells, tissues, or organs. This process of early degradation or functional decline is determined by internal, constitutional, or genetic factors, manifesting in the absence of obvious external aggressions.
• To abjudicate — To deprive someone of a right, a property, or a status through a court ruling or an official decision; to legally contest and revoke a title or asset previously held by a person. In modern procedural law, the term is rarely used, being replaced by concepts such as expropriation, forfeiture of rights, or revocation of a title.
• Abjuration — The act of abjuring and its result; the public, solemn, and formal renunciation of a belief, doctrine, or sacred promise. In a historical context, abjuration represented a written legal-religious act, often required for the reconciliation of an individual with the ecclesiastical community from which they had been excluded.
• Abjuration (variant) — A neologistic form or rare variant for 'abjurare'; the actual act by which a person renounces their faith or principles through a solemn declaration. In certain older theological or legal texts, the term designated the written formula or ritualistic text that the accused had to read aloud.
