You are right to expect us to show some interest in clinical neuroses.
Their close clinical relationship with psychoneurotic disorders actually requires such an interest. So, let me tell you that we distinguish three pure forms of clinical neurosis: Neurasthenia, anxious neurosis, hypochondria.
The symptoms of clinical neurosis often constitute the core and the initial stage of the psychoneurotic symptom. A relationship of this kind is clearly observed between neurasthenia and conversion neurosis, known as conversion hysteria, between anxious neurosis and anxious hysteria, as well as between hypochondria and the forms of neurosis that we will examine later, namely paranoia (early dementia and paranoia).
