Behind iatrogenic disturbances caused by psychological factors lies th
e dependence of present day medicine on the reductionist scientific pa
radigm of the 18th century. The latter excludes psychological and soci
al factors from the ''scientific equation''. Only absolute objectivity
and neutrality in the observer, and the avoidance of personality and
history in the patient, are held to be valid. The patient's individual
reality, as influencing his individual physiology, is not considered.
The results are errors in diagnosis (e.g. with patients suffering fro
m chronic pain), abuse (including sexual) of women patients, and insuf
ficient care of cancer patients. Psychological iatrogenic disturbances
can be reduced by training medical students in biopsychosocial interr
elations and by self-experience courses for physicians.
