• Abulias — The plural form of the neological noun 'abulie', designating the pathological states characterized by the total absence or severe diminution of willpower, decision-making capacity, and the impulse to act. Frequently manifesting as core symptoms in major depressive episodes, schizophrenia, or neurological disorders of the frontal lobe, these disturbances block an individual's ability to initiate and sustain goal-directed activities, despite their physical and intellectual capacities remaining intact.
