The author begins his investigation of hypochondria by defining the conditi
on and distinguishing between hypochondriacal symptoms and hypochondriacal
crises, the latter being stated to arise when the defensive function of the
former fails. After an enumeration of the main psychogenetic element obser
ved in the psychoanalytic psychotherapy of a sample population of eight pat
ients, he concentrates on the psychodynamic and psychostructural aspects an
d demonstrates by means of clinical examples how conflicts of separation an
d dependence give to oral-sadistic, anal-sadistic and progressive-perverse
defensive structures. Although regressive and progressive psychodynamic pro
cesses established between these structures may temporarily stabilise the p
sychic system to some extent, splits cause them to loom large in a hypochon
driacal world full of disintegrative anxiety that is accompanied by an aggr
essive excitation pervaded with threatening confusion and sexual perversion
, where the patient flees into quasi autistic withdrawal and tormenting sel
f-observation. Catastrophic states resulting fron earlier traumas are here
fused with more mature psychic elements owing to earlier traumas. The autho
r shows how instability in these structures, together with the failure of i
mportant ego and superego functions, may lead to a malignant regression and
the consequent pathogenic reintrojection of projections. When the psyche i
s threatened by a dynamic of this kind, hypochondriacal symptoms may ensure
as a last-ditch attempt by the patient to defend against psychic decompens
ation.
