Psychology is the study of the human mind. This medical speciality studies behaviour of human beings and also their internal and external motivations.
A psychologist is a professional who has undergone both university training and personal training (personal development through psychotherapy).
The patient is supported in the questioning he/she has decided to do of him/herself. A psychologist is not a doctor and cannot therefore prescribe medical drugs. His/her profession is above all one of listening and assisting.
