Aprosexia, Hyperprosexia, and Paraprosexia are closely related medical and neuro-psychiatric phenomena associated with attention and concentration. They typically occurs in patients suffering traumatic brain injuries.
Patients suffering traumatic brain injury experience profound disturbance of the basic functions of the cognitive, behavioral, emotional and intellectual systems. Such patients' ability to regulate interaction between the ego and the external world is greatly diminished and they typically exhibit inflexible, concrete and sometimes inappropriate behaviors.
