Hypobulia is one of the main syndromic formations identified by the German psychiatrist Ernst Kretschmer, the founder of the “anatomical trend” in psychiatry. Kretschmer based his classification on the idea of different variations in the structure of the human body and personality. For example, asthenics have an elongated figure, always dress so that their legs are visible, and love long shoes. Kretschmer introduced the phenomenon of dissimulation into psychological science, by which he understood one of the methods of mental self-defense, that is, people demonstrated non-aggressive behavior after displaying aggressiveness in order to achieve positive results (for example, receiving the highest reward, help, work, etc.). Based on this, and also taking into account constitutional features, Kretschmer identified various forms of hypobulia: asthenic, schizoid, psychasthenic and hyperbulic.
For example, asthenic people are characterized by increased sensitivity to surrounding external stimuli. They are more likely than other people to be injured or infected (for example: various infections), since their nervous system is in a state of heightened excitement, distracted, and overexerted. People with an asthenic constitution are sensitive to any changes in climate, weather, pressure, temperature, lighting, noise, touch and environmental odors
