Results Suicidal behavior were more frequent among females
with previous psychiatric history. The most used method was
medication overdose. Psychiatric comorbidity like depression and
substance abuse were commonly present. The majority of suicide
attempt patients were discharged without hospitalization.
Conclusions The emergency room is a vital setting for suicide
prevention and may be the only access to healthcare available for
some patients. The physicians must be capable to quickly assess the
potential lethality of a suicidal behavior and create a safe treatment
plan to prevent future suicide attempts.

Suicide risk assessment and
prevention interventions in military
veterans
A. Teo

Introduction Concerns over suicide among military veterans has
been as issue of major public and policy concern, particularly by
the Veterans Health Administration (VHA), which is the largest
integrated health care system in the United States.
Objectives and aims The reasons for suicide risk and means to
reduce risk in this population have been under active investiga-
tion and implementation. The aim of this presentation is to review
recent trends in suicide risk assessment and suicide prevention
interventions within the VHA in the United States.
Methods A literature review consisting of an electronic database
search of PubMed, “gray literature” search, and manual search for
articles related to suicide in military personnel and veterans was
conducted.
Results In recent years, annual VHA rates of completed sui-
cide have ranged from approximately 34 to 40 suicides per
100,000 person-years, rates significantly higher than the general
US population. Risk assessment methods examined in military vet-
eran populations have primarily included self-report instruments,
scales, and checklists. Recently, “big data” approaches to analysis
of electronic medical records have shown promise in stratifying
veterans into high- and low-risk groups. VHA suicide prevention
initiatives have included extensive staff hiring, development of
research centers and data-sharing agreements focused on suicide,
a national telephone crisis line, routine suicide risk assessment and
screening, and suicide safety plans.
Conclusions Military veterans in the US receiving care in the VHA
have a variety of risk factors for suicide and continue to be at ele-
vated risk despite implementation of numerous suicide prevention
initiatives.

A new evidence-based
neuropsychological model of suicidal
propensity and suicide based in
depression
L.-H. Thorell
Linkoping University, Linkoping, Sweden
Introduction Objectively validated models of the depressed
suicide are lacking. Early observations that electrodermal hypore-
activity was strongly related to suicide in depression required an
untraditional statistical approach that was applied on materials
from published materials with between themselves totally con-
firming results.
Objectives A plausible explanation model of the relationship had
to be developed.
Aims The aims were to investigate the nature of electrodermal
hyporeactivity and its possible causes and connections to other
suicide relevant factors and to formulate a coherent model of the
depressed suicide.
Methods Published materials with in- and outpatients (in
total > 900 patients) comprising follow-up of suicide and tests of
habituation of the electrodermal response were analysed. Symp-
tomatology, gender, age and other variables were considered and
so were knowledge and theories from other scientists.
Results The apparent loss of or considerably reduced specific
electrodermal orienting (curiosity) responses in future depressed
suicide victims showed clear relationships to and clear indepen-
dence of considered important suicidal factors.
Conclusions Loss of specific orienting responses indicates loss
of hippocampal CA3 plasticity. CA3 areas are early and centrally
positioned in the information processing of neocortical sensory
input supporting the hypothesis of a particular neuropsychologi-
cal dysfunction disabling normal cognitive and emotional curiosity
reactions to everyday events. It is proposed that this dysfunction
may make the depressed person ready to leave the everyday life
and fearless of imminent pain – a loss of two important barriers
against suicide.
It seems righteous to propose this basically objectively validated
model as a plausible explanation of the depressed suicide.

Attempted suicide among patients
attending neuropsychiatry
department – a study from tertiary
care neuroscience hospital in
Bangladesh
M.M.J. Uddin
National Institute of Neurosciences and Hospital, Psychiatry, Dhaka,
Bangladesh
Introduction Attempted suicide is a growing problem with sig-
nificant clinical and public health importance globally as well as
developing countries like Bangladesh. Psychiatric disorders are the
most common reasons for suicide or suicidal behavior among other
causes of such behavior.
Objective The objective of the study was to find out the sui-
cide attempters among the patients with psychiatric disorders
attending the neuropsychiatry department of National Institute of
Neurosciences and Hospital (NINS&H), Dhaka, Bangladesh.
Methodology This descriptive cross-sectional study was done in
NINS&H, Dhaka, Bangladesh from July 2013 to August 2014. Psy-
chiatric diagnoses of the patients were done by the psychiatrist
following Diagnostic and Statistical Manual of Mental Disorders
– IV-Text Revision (DSM-IV-TR) diagnostic criteria. Ethical issues
were maintained strictly.
Results Total 63 patients were found with history of single or
more than one suicidal attempt out of 954 patients. Among the sui-
cidal attempters, 34 (53.97%) were male and majority 38 (60.32%)
belonged to 20 years to 40 years age group. In this study, the most
common methods of suicidal attempt were found taking over dose
of sedatives and multiple drugs 22 (34.92%), ingestion of pesticides
and other corrosive agents 17 (26.98%) and hanging 14 (22.22%).
Psychiatric disorders wise distributions of suicidal attempters were
found major depressive disorder 18 (28.57%), borderline personal-
ity disorder 14 (22.22%), schizophrenia and related disorders 10
(15.87%).
