Probably, an important aspect is the anhedonia secondarily pro-
duced by neuroleptics.
Objective We want to evaluate if Paliperidone Palmitate reduces
addictive behaviors in a small group of psychotic patient who have
agreed to recived injection after the switch from other antipsy-
chotics.
Method We have identified four individual with chronic use of
drugs of abuse in aMental Health Center. These subjects were abus-
ing alcohol, cannabis, spice and benzodiazepine. We administered
before new treatment and after 2 months the Snaith-Hamilton
Pleasure Scale of Snaith et al. (1995) and the Leeds Dependence
Questionaire of Raistrick et al. (1994).
Results The hedonic tone tends to improve and the addictive
behavior decreased.
Conclusion The therapywith Paliperidone Palmitato is associated
with a reduction of the addictive behaviors but we need studies
with a larger number of patients.

Introduction Only few international studies have focused on
mental diseases among the hearing-impairedpopulation. However,
Fellinger et al. (2012) underline the high discrepancy between the
current and future demand of mental treatment and the simulta-
neous impeded access to health care.
Aims The aim of this multicenter project is to conduct the first
analysis of mental diseases among the hearing-impaired popu-
lation in Germany in order to quantify and qualify the specific
demands of treatment.
Objectives In order to achieve this aim, we compiled an extensive
questionnaire battery.
Methods This questionnaire battery measured sociodemo-
graphic data, non-verbal intelligence, quality of life, perception and
suffering from stress, psychosomatic symptoms as well as person-
ality traits.
Results Our three samples consisted of 21 hearing-impaired
patients with a history of mental diseases (EG-HI), 21 hearing-
impaired subjects without mental diseases (CG-HI) and 21 hearing
participants without any psychological disease (CG-H). Compared
to the two control groups, the EG-HI shows significantly higher
rates in different fields, i.e. participants perceive a lower quality
of life, suffer from more psychosomatic symptoms and show more
pronounced personality traits. The two control groups did not differ
significantly from each other.
Conclusions Certain psychological characteristics among
hearing-impaired patients can be detected which need to be
accounted for in treatment. Furthermore, a hearing impairment is
not inevitably linked to a reduced quality of life or even mental
disorders. Therefore, future research should focus on risk factors
and protective factors which could prevent mental diseases among
the hearing-impaired population.

Introduction Stuttering is a speech disorder characterized by
involuntary repetition, prolongation or cessation of a sound. This
dysfluencymay be developmental or acquired. Acquireddysfluency
can be classified as neurogenic or psychogenic.
Objectives This case report aims to describe and discuss a case
of psychogenic stuttering, providing an updated review on this
disorder.
Methods In and outpatient interviews were performed by Neu-
rology and Psychiatry. Investigation to exclude organic causes
included lab exams, electrocardiogram, electroencephalography,
computed tomography scan and magnetic resonance imaging. A
literature review in Science Direct database, with the keywords
“psychogenic stuttering”, was also conducted.
Results A 63-year-old man was admitted to the Beatriz Ângelo
Hospital with an acute stuttering. Speech was characterized by the
repetition of initial or stressed syllables, little affected by reading
out loud or singing. Comprehension, syntaxes and semantic were
not compromised, as weren’t sensory and motor abilities. Dur-
ing admission, stuttering characteristics changed. Multiple somatic
complaints and stress prior to the onset and bizarre secondary
behaviors were also detected. Work-up didn’t show an organic
etiology for that sudden change. An iatrogenic etiology was con-
sidered, as sertraline and topiramate were started for depression 1
month before. However, the stuttering pattern, the negative results,
the psychological and the social life events suggested a psychogenic
etiology.
Conclusions Psychogenic stuttering finds its origin in psycholog-
ical or emotional problems. It is best classified as a conversion
reaction. The differential diagnosis between psychogenic and neu-
rological stuttering can be challenging.

Objectives The revision of the differential diagnosis of simulation
cases versus real psychopathological cases. Analysis of a case of
the Ganser syndrome by revising the diagnosis criterions and their
historical characteristics.
Method We analyze the case of a 38-year-old male who came
to the community mental health team and reference hospital. Fol-
lowing symptoms were observed: involuntary movements of the
upper extremities associated with delirium coinciding with the
