during which the full symptom criteria, for a manic, hypomanic
or a depressive episode had been met. He was also reported to be
hyperactive, impulsive, and had difficulty concentrating and focus-
ing since he was seven. Laboratory evaluations were within normal
limits. Results of screening forms provided by parents and teachers
supported the presence of attention deficit and hyperactivity dis-
order (ADHD). ASRS, YMRS, STAXI, SCID-I, Diagnostic Interview for
Adult ADHD (DIVA) were the psychometric evaluations carried out
in order better to characterize the clinical situation.
Results He was considered as fulfilling DSM-5 criteria for
ADHD and DMDD, and started on sertraline 50mg/day and
OROS methylphenidate 36mg/day. At the following visits, temper
tantrums were much reduced and there were moderate improve-
ment in ADHD symptoms.
Conclusions By defining the adult manifestations of DMDD accu-
rately, clinicians will be able to improve diagnosis and care.

Introduction The term, acute and transient psychosis, is com-
prehended as a heterogeneous group of disorders, which share,
as a common feature, the abrupt and brief deployment of
typical psychotic behaviour, either polymorph, delusional, or
schizophreniform. This diversity of symptoms may also be present
in other psychotic disorders, for which, some authors question its
reliability.
Objetive To analyse the clinical manifestations present in acute
and transient psychotic disorders (ATPD), and determine the dif-
ferences between its different subcategories.
Method Retrospective chart review study of adult patients
admitted in our psychiatric unit between 2011 and 2015, with a
mean diagnosis of ATPD at hospital discharge. Diagnostic criteria
was according to the International Classification of Diseases (ICD-
10). Symptoms were divided under operative procedures, as set
out in psychopatologic descriptions. For methodological reasons,
statistical analysis was conducted between polymorphic features
group (PM) and nonpolymorphic group (NPM). Chi-squared test
and Fisher’s exact test (as appropriate) were performed, usingMed-
Calc software.
Results Thirty-nine patients met the inclusion criteria. Acute
polymorphic psychotic disorder with and without symptoms of
schizophrenia (39%), acute schizophrenia-like psychotic disorder
(20%), acute predominantly delusional psychotic disorder (23%),
other and NOS (18%). There were statistically significant differ-
ences between PM and NPM groups in emotional turmoil (>PM,
P = 0.0006), grossly disorganized or abnormal motor behaviour
(>PM, P = 0.0038), and type of onset (sudden >PM, P = 0.0145).
Conclusion Currently, the same concept encompasses two cate-
gories (PM and NPM) to be differentiated. The ATPD construct is
under review, due its long-term instability.

Introduction In the recent decades, there is a growing interest in
gender differences in psychotic disorders. Also, in the field of acute
and transient psychosis, according to various studies, women seem
to have higher prevalence and long-term diagnostic stability.
Objectives To determine whether there are gender differences in
clinical features of acute and transient psychotic disorders (ATPD).
Methods Descriptive cross-sectional study in the adult patients
with ATPDwere admitted between 2011 and 2015 in our acute psy-
chiatricward. Diagnostic criteriawas according to the International
Classification of Diseases (ICD-10). Descriptive and inferential
statistic procedures for clinical symptoms and diagnostic subcat-
egories were performed, using the MedCalc software, version 15.8.
Results Thirty-nine patients met the inclusion criteria. Males
were (MG) 41%, females (FG) 59%. There were some statistically
significant differences between gender in the polymorphic features
group (>FG, P = 0.048), and in the presence of acute stress (>FG,
P = 0.0277). Length of stay was also different, but without statis-
tical significance (>MG, P= 0.0607). In contrast, symptomatic sets,
family history of psychosis, and type of onset (sudden or acute)
were similar for both groups.
Conclusions The gender differences seem to be in favour of a
higher prevalence of polymorphic psychotic symptoms, in relation
to stressful events in women. Somehow, these factors could be a
condition, which would determine a greater diagnostic stability in
female patients, even in cases of recurrences.

Introduction The new edition of the DSM has introduced some
changes involving differences, sometimes significant, in the con-
ceptualization and classification of mental pathology. One of the
most important has been the case of mental retardation.
Objectives and aims Discuss, with a clinical and pragmatic per-
spective, the relevance of those changes in the diagnosis and
classification of mental retardation in DSM.
Methods A 45-year-old woman diagnosed with mental retarda-
tion is admitted in a psychiatric rehabilitation unit for behavioral
disorders and psychotic symptoms. Once controlled the symptoms
and studied the patient, a disability not corresponding with the
diagnosis presented (mild mental retardation according to DSM IV)
is shown. Clinicians start a reevaluation of the diagnosis.
Results A comprehensive rehabilitation programaccording to the
pathology and deterioration of the patient is designed. With the
diagnosis review is possible to find new resources and community
programs, better fit for the patient needs.
