Emotions affect a large proportion of psychiatric disorders and are involved in practically all psychopathological symptoms and syndromes. Unfortunately, many of the questions about emotions cannot be answered today or are hotly debated; this concerns the various research directions: Research is being conducted in Affective Neuroscience, Psychiatry, Psychology, and also in the Humanities. Another question that should be posed at the beginning is: Is the conscious experience of emotions the decisive factor, i.e., the experience of mood or the unconscious effects of emotionality, or could it also be the physical and mental phenomena associated with them? What can we consider as established when we try to explain the disturbance of emotions?
