weight loss for the past month. In the days preceding his presen-
tation, he has experienced worsening irritability and rapid speech,
and has been responding to internal stimuli and displaying odd
repetitive movements of his extremities. On interview, the patient
reported non-compliance to his prescribed Lithium and Paroxetine
for the past threemonths. He also noted recently smokingmetham-
phtamine on a daily basis for the past month and intermittently
abusing cannabis, benzodiazepines and cocaine. His urine drug
screen was positive for cannabinoids and amphetamines and the
rest of his medical workup was within normal limits. On physical
exam, he exhibited involuntary writhing and twisting movements
of his extremities. An atypical antipschotic was prescribed, after
which his choreoathetotic movements resolved within 24 hours.
The purpose of this poster is to highlight the possibility of devel-
oping chorea as a result of methamphetamine use, given the rarity
of such cases, and to discuss whether the resolution of his neu-
rological symptoms were a result of antipsychotic administration
or were simply due to the natural course of methamphetamine
discontinuation during hospitalization.

Introduction Anxiety and depression, as well as alcohol use are
widespread among teenagers, and constitute a huge public health
burden worldwide.
Objective To study the link between alcohol consumption and
emotional distress (anxiety and depression) among adolescents.
Methods We conducted a cross-sectional study in May and June
2016. The sample consisted of 314 pupils from 4 colleges and
schools in Sfax (Tunisia). Alcohol Use Disorders Test (AUDIT) was
used to evaluate alcohol dependence. Anxiety and depression levels
were evaluated using the “Hospital Anxiety and Depression Scale”
(HADS).
Results Themean agewas 16 yearswith a sex ratio of 1.08. Among
the participants, 18.9% reported having drunk alcohol at least once
and 42.37% of them still consume. The main reasons for alcohol ini-
tiation were the search of new experiences (78%) or pleasure and
well-being (39%) and the curiosity (49.15%). According to AUDIT,
1.7% of alcohol users presented an alcohol misuse and 20% pre-
sented dependence.
The prevalence of anxiety and depression were respectively 56.1%
and 23.7%. Anxiety was correlated to alcohol experimentation
(P = 0.03) and non-supportive environment (P = 0.003). Depression
was correlated to alcohol experimentation (P = 0.001), AUDIT score
(P = 0.009), somatic histories ( P = 0.02), physical abuse (P = 0.02),
non-supportive environment (P = 0.016) and graduating class level
(P = 0.005).
Conclusion Our study highlights the close association between
alcohol consumption and emotional distress in adolescence, which
seems to be bi-directional. When attempting to reduce the risk
of alcohol consumption, we should focus a particular attention
on adolescents studying in graduating class, reinforce adolescents’
family support and prevent physical abuse.

Aim The aims of the present study was to investigate the long-
term stability of problematic gaming among adolescents, and
whether problematic gaming at wave 1 (W1) were associated with
problematic gambling at wave 2 (W2), three years later.
Methods Data from the SALVe-Cohort, including adolescents
in Västmanland born in 1997 and 1999, at two waves were
analyzed (W1, n = 1868; 1035 girls, W2, n = 1576; 914 girls).
Adolescents self-rated the Gaming Addiction Identification Test
(GAIT), Problematic Gambling Severity Index (PGSI), and gam-
bling frequencies. Stability of gaming using Gamma correlation,
and Spearman’s rho was performed. General linear model anal-
ysis (GLM), and logistic regression analysis were performed,
adjusted for sex, age, and ethnicity using PGSI as dependent
variable, and GAIT as independent variable, for investigat-
ing associations between problematic gaming and problematic
gambling.
Results Problematic gaming was stable over time, = 0.810,
P ≤ 0.001, and = 0.555, P ≤ 0.001. Furthermore, problematic gam-
ing at wave 1 increased the probability of having problematic
gambling three years later, GLM F = 3.357, 2 = 0.255, P ≤ 0.001,
and logistic regression OR = 5.078 (95% CI: 1.388–18.575), P = 0.014.
Male sex was associated with higher probability of problematic
gambling.
Conclusions The present study highlights the importance of
screening for problematic gambling among problematic gamers in
order not to overlook possible coexisting gambling problems. The
stability of problematic gaming indicates a need for development
and evaluation of treatment for problematic gaming and also for
coexisting gambling problems.

Introduction Autism and substance use disorder (SUD) is not the
co-morbidity that is commonly considered. Yet these conditions
have more commonalities than one would suspect.
Objective We will consider the evidence for co-morbidity
between ASD and Addiction (Substance Use Disorders (SUD) and
explore the influence of gender.
Method A pilot study of 80 admissions to an adult ASD unit will
be presented.
Results The co-morbidity ASD and SUD in this study was very
high (65% of the inpatients). There were no gender differences in
prevalence in total but addiction to medication (32% in woman
vs. none in man) and eating disorders (24% in women vs. 9%
in man) was far more common in women whereas addiction to
drugs (13% in man vs. none in women) was far more common
in man.
Conclusions There are clear indications that a possible co-
morbidity of substance abuse disorder should be considered in
cases of individuals with autism spectrum disorders. There are no
gender differences in prevalence of co-morbidity ASD and SUD in
