The synthetic psychosis substances
induced: A clinical case study

The presentation intends to examine a new kind of clinical psychi-
atric syndrome, called by the author “synthetic psychosis”, which
can occur in people who abuse novel psychoactive substances
(NPS). This syndrome will be considered from both a psychopatho-
logical and a phenomenological perspective. The contemporary
trend of poly-abuse of NPS in young people can lead to a sort of
very intense paraphrenic state characterised by continuous hal-
lucinations and formed by a mental automatism syndrome and
by secondary (interpretative) delusions. The clinical case of G.,
discussed in this paper, is an exemplary case of this synthetic
psychosis. The psychopathological understanding of the core sym-
ptomatology of the patient examined has been fundamental for the
successive therapeutic approach. If this attempt at understanding
is ineffective, the frequent consequences include: the worsening
of the psychopathology and addiction; the patient’s admission into
a psychiatric hospital; his/her arrest for crimes related to antiso-
cial behaviour; a diffusion of infective diseases commonly found
in addicts; more frequent overdoses; aggressive behaviour; an
increase in the costs of public health system and, finally, the suicide
of the patient

Introduction
Corollary discharges (CDs) are the reason most
people cannot tickle themselves. They are the brain’s way of distin-
guishing whether a stimulus is associated with one’s own actions
or something else. In neural terms, CDs are copies of motor plans
that are propagated to sensory cortex where they can be compared
with inputs. A range of phenomena associated with schizophre-
nia from auditory hallucinations to visual processing difficulties
to the ability of patients to tickle themselves can be explained as
pathologies in CD mechanisms. Auditory hallucinations for exam-
ple involve patients failing to perceive themselves as the author of
their own inner speech.
Objectives and aims
To test whether schizophrenia is associated
with a structural network disruption that could impair CD signals
involved in language processing, adolescents with schizophrenia
were examined using magnetic resonance imaging and compared
to healthy controls.
