Historical Dictionary of Psychiatric Syndromes

• 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.
