• Ab hoc et ab hac — A Latin phrase literally translated as 'from this one and from that one' or 'about this and about that'. In clinical psychology, neurology, and psychiatry, it describes a chaotic, incoherent speech with no logical connection between ideas, typical of patients experiencing delirium episodes, dementia, acute mental confusion, or severe intoxication with psychoactive substances.
• Abderaman — An eponym derived from the name of Caliph Abd ar-Rahman, used historically in early European and Romanian medical literature to describe a specific type of grandiose delusion with a mystic-exotic theme or religious monomania. In 19th-century psychiatric semiology, the term identified patients who assumed imperial or oriental caliphal identities during psychotic or manic episodes, studied within classic alienism.
• abdominoscopie — An archaic or historical diagnostic method consisting of the direct visual examination of the abdominal cavity and internal organs using an abdomenoscope inserted through a small incision in the belly wall. In early neuropsychiatric semiology, performing an abdominoscopy served as a differential diagnostic tool to exclude real tumoral or inflammatory pathologies in alienated patients presenting with severe somatic fixations, persistent hypochondriacal delusions, or pseudocyesis phenomena (imaginary pregnancy).
• Abdul — A cultural and historical eponym originating from an oriental proper name, sporadically used in early European and Romanian psychiatric semiology to describe a specific form of grandiose delusion with an exotic theme (Abdul delusion). In 19th-century insane asylums, the term characterized patients exhibiting mystic or political monomania, claiming to be sultans, oriental rulers, or Asian divinities, studied within classic eponymic psychoses.
• Abdul-Hamid — An eponym derived from the name of Ottoman sultans (such as Abdul-Hamid II), historically used in 19th-century European and Romanian psychiatric literature to describe a typical case of political monomania or persecutory delusion combined with megalomania. In classic alienism semiology, the term qualified psychotic states where patients, dominated by extreme pathological suspicion and fear of conspiracies (paranoia), simultaneously assumed an absolute autocratic identity and harbored obsessive fears of poisoning.
• Abdul-Medjid — A clinical eponym drawn from Ottoman imperial onomastics (Sultan Abdul-Medjid I), rarely used in the terminology of 19th-century Romanian and European asylums. It denoted a particular manifestation of melancholic delusion or exhaustion psychosis, characterized by ideas of unrealistic universal reform mixed with profound apathy, morbid sadness, and feelings of helplessness before destiny, with the patient considering himself a misunderstood or dethroned monarch.
• Abdulah — An archaic orthographic variant of the eponym 'Abdul' or 'Abdullah', rarely used in 19th-century medical-legal reports and clinical charts within early Romanian asylums. In the context of classic alienism, the term served as a generic semiotic descriptor to categorize manifestations of religious monomania or exotic grandiose delusion, where the patient identified himself as a prophet, caliph, or prince from oriental dynasties.
• Abdullah — A historical eponym derived from oriental dynastic or religious onomastics, used in 19th-century European and Romanian psychiatry. In classic alienist classifications by Esquirol and Baillarger, the term served to illustrate a specific type of mystic-exotic monomania or grandiose delusion, describing patients with severe psychotic or manic episodes who declared themselves absolute oriental sovereigns, blending ideas of secular power with religious infallibility.
• Abenceragi — A historical and cultural eponym derived from the name of the noble Moorish Abencerrages lineage of Granada, sporadically used in 19th-century classical psychiatric literature and psychoanalytic analyses (the Abenceragi syndrome or complex). In old alienism semiology, the term described a specific variant of melancholic delusion mixed with ideas of lost family pride, chronic resentment, and paranoid suspicion of plotted betrayal. It characterizes patients exhibiting an obsessive monomania centered on the symbolic revenge of a clan's honor or on experiencing a morbid, destructive nostalgia for an idealized glorious past.
• abenceraj — The singular form of the clinical eponym 'Abenceragi', designating a type of psychopathological structure characterized by romantic melancholia, deep chronic resentment, and paranoid ideas of dynastic betrayal. In 19th-century classical alienism, the term described a patient developing an obsessive monomania centered on the loss of honor or the idealized collapse of their clan, living in a strict defensive isolation.
• abera — To deviate from normal mental, cognitive, or behavioral manifestations; to express delusional, incoherent, or clinically illogical ideas during a psychotic episode, acute febrile state, or delirium. In early semiology, the term described the wandering of the mind or the deviation of an organ from its natural anatomical function or trajectory.
