Introduction Chronic excessive alcohol consumption may lead
to structural and functional damage of the brain. Alcohol-related
cognitive impairments are well-established and confirmed by neu-
ropsychological and neuroimaging studies. However, the influence
of each neuropathological mechanisms is still under discussion.
This topic is increasingly becoming focus of attention in psychiatry.
Objectives Review the neuropathology, clinical features, neu-
ropsychology and management of alcohol-related cognitive
impairments.
Aims Evaluate clinical impact, management and prognosis of
alcohol-related cognitive impairments.
Methods A literature searchwas performed on PubMed andMed-
scape database.
Results According to our literature research, there is a debate
concerning the relative contributions of the direct toxic effect of
alcohol and the impact of thiamine deficiency on the alcohol-
related cognitive impairments. Research about this issue is
challenging, considering the multiple patterns of alcohol abuse, the
personal and lifestyle factors, and the vulnerability of specific brain
regions. The cognitive decline is linked to neuroanatomical alter-
ations and primarily affects executive functions, episodic memory,
and visuospatial capacities. These deficits may range from mild to
severe but usually remain undiagnosed, unless they are specifi-
cally investigated. Maintenance of lasting abstinence is associated
with cognitive recovery, but some impairments may persist and
interfere with the prognosis.
Conclusion Recognizing and screening for alcohol-related cogni-
tive impairments is crucial to offer significant benefits to patients
by optimising management strategies.

Introduction The Internet is commonly used in modern society;
however, Internet use may become a problematic behaviour. There
is an increasing need for research on problematic Internet use (PIU)
and its’ associated risk factors.
Objectives This study aims to explore the prevalence and health
correlates of problematic Internet use among South Korean adults.
Methods We recruited the participants aged between 18 and
84 years old among the online panel of an online research ser-
vice. The sample size of the survey was 500. Of these 500
participants, 51.4% ( n = 257) were men and 48.6% (n = 243) were
women. A participant was classified as a problematic Internet
use (PIU) if his/her total score of Young’s Internet Addiction
Scale (YIA) was above 50. Stress Response Index (SRI), Fager-
strom test for nicotine dependence, lifetime average caffeine
consumption, and sociodemographic query form were used in the
collection of data. The t test and chi-square test were used for data
analysis.
Results One hundred ninety-seven (39.4%) of the participants
was classified into the PIU group. There was no difference of gen-
der and education between PIU and normal users. However, PIU
group was younger (mean 39.5 years) than normal users (mean
45.8 years). PIU group was more likely to have high levels of
perceived stress, nicotine dependence, and drink more often caf-
feinated beverages ( P< 0.05).
Conclusions These data indicate that problematic Internet use is
associated with perceived stress level, nicotine and caffeine use
in South Korean Internet users. More research is needed to bet-
ter understand the relationship between Internet use and mental
health issues.

Introduction Exercise addiction is a condition described by
a craving for physical training resulting in excessive exercise
behaviour and withdrawal symptoms. It has not been accepted as
a mental disorder and further research is needed to examine the
pathology of the condition.
Objectives Exercise addiction is suggested to have links to
other mental disorders and risks in terms of negative con-
sequences such as injuries. Treatment for exercise addiction
faces several challenges as the condition is associated with
ambivalence, and studies based on controlled interventions are
missing.
Aims The aim of this study was to examine and interpret the
existing research on links, risks and challenges faced in treatment
interventions.
Methods A literature review was conducted in the databases
PubMed, PsycINFO and Scopus with the terms: “exercise addiction,
excessive exercise” and/or “comorbidity, eating disorder, depres-
sion, anxiety, personality, pain, injury, illness, social isolation,
stress, intervention, treatment”.
Results Exercise addiction seems to be associatedwith eating dis-
order pathology, obsessive-compulsive behaviour and personality
