“…Regarding the methods of suicide attempt, individuals with schizophrenia tended to make attempts of moderate to extreme lethality [28], [29] or often died by violent means [30]. In the present study as well, the ratio of ‘absolutely dangerous’ methods was significantly higher in the F2 group, and patients in the F2 group tended to make suicide attempts by more serious methods such as ‘jumping from a height’ and ‘jumping in front of a moving train or high-speed car’.…”

Recent reports suggest a lifetime suicide risk for schizophrenia patients of approximately 5%. This figure is significantly higher than the general population suicide risk consequently, detection of those at risk is clinically important. This study was undertaken to define the characteristics of suicide attempts by schizophrenia patients compared with attempts by patients with mood disorders. All patients were diagnosed using the ICD-10 criteria. The study population comprised 65 patients with F2 disorders (schizophrenia, schizotypal and delusional disorders), i.e., “the F2 group”, and 94 patients with F3 disorders (mood disorders), i.e., “the F3 group”, who presented in the clinical setting of consultation-liaison psychiatry. The F2 group had a significantly younger mean age and significantly higher ratios of ‘past/present psychiatric treatment’ and ‘more than 3 months interruption of psychiatric treatment’. In contrast, the ratios of ‘physical disorder comorbidity’, ‘alcohol intake at suicide attempt’ and ‘suicide note left behind’ were significantly higher in the F3 group. The F2 group attempted suicide by significantly more serious methods. Furthermore, ‘hallucination-delusion’ was the most prevalent motive in the F2 group and was the only factor that showed a significant association with the seriousness of the method of suicide attempt (OR = 3.36, 95% CI: 1.05–11.33).

“…Specific risk factors linked to schizophrenia that increase seriousness of suicide attempts include: illness chronicity with many acute psychotic episodes and remissions, a prevalence of positive symptoms (such us suspiciousness and delusions), awareness of the illness' disabling effects and fear of further disability, despair and loss of confidence (Harkavy-Friedman et al, 2003;De Hert et al, 2001;Funahashi et al, 2000;Nieto, Vieta, Gasto, Vallejo, & Cirera, 1992). The presence of elevated impulsive and aggressive traits increases the lethality of suicide attempts and generally leads to employing serious methods, like jumping from heights, jumping before a train, hanging, firearms, stabbing or burning oneself (Huisman et al, 2010;Koeda et al, 2012;Nieto et al, 1992).…”

BACKGROUNDSuicide in psychiatric illnesses is mostly seen in mood disorders followed by schizophrenia. This study is an attempt to compare the risk factors associated with suicide in bipolar affective disorder and schizophrenia. MATERIALS AND METHODSThe study was a descriptive comparative study. Thirty patients with schizophrenia and thirty patients with bipolar affective disorder with suicidal ideation and/or suicidal attempts were analysed for their socio-demographic and illness characteristics. RESULTSAll the patients had suicidal ideations and there were 16 suicide attempters. There were more illiterates with bipolar disorder. The younger bipolar patients tended to have higher scores for suicidal ideation and intent. The suicidal ideation increased with the level of education (p= 0.027). All patients had depression. All suicidal attempts were associated with severe suicidal ideation. The severity of suicidal ideation increased with the number of previous attempts. CONCLUSIONThis study justifies the need for regular followup and screening for suicidal ideations in both schizophrenia and bipolar disorders considering the aforementioned factors. Of the various mood disorders, depression is most frequently associated with suicide. Untreated depression has a lifetime risk of suicide from 2.2% to 15%. Mania, though rare has also been shown to lead to increased suicide risk. Other, Competing Interest: None. Submission 24-06-2017, Peer Review 18-07-2017, Acceptance 24-07-2017, Published 31-07-2017.

E-mail: saravanajothi@gmail.com DOI: 10.14260/jemds/2017 Male gender, family history of suicide, suicidal ideation, psychotic symptoms, former suicide attempts, hopelessness, comorbid personality disorders, substance use and anxiety disorders have been found to be contributing determinants towards completed suicide in many prospective cohort studies. (3) In people with schizophrenia, it has been demonstrated that there is a suicide risk of 5%. (4) Risk factors in schizophrenia include early onset of disease, male gender, unemployed, higher levels of education, rural, comorbid physical illness, depression, positive symptoms and presence of insight. KEYWORDS Financial orIn a retrospective study by Takao Ishii et al, (5) comparison of the characteristics of suicide attempters among schizophrenics and those with unipolar and bipolar mood disorders found differing characteristics among the groups in relation to their age, comorbidities, severity of attempt and treatment interruption. The study did not include patients with suicidal ideations and included patients with both unipolar and bipolar mood disorder. This study focused on the patients diagnosed with schizophrenia and bipolar disorder harbouring suicidal ideations and/or attempts in the Indian population. The study also tried to seek an association between suicide attempt and mania, for which much literature is not available.
