Characteristics of suicide from 1998-2001 in metropolitan area

Psychiatric and psycho-social characteristics of suicide completers: a comprehensive evaluation of psychiatric case records and postmortem findings

Objectives

To explore the demographic, psychosocial and clinical characteristics of individuals known to the mental health services, who died by probable suicide in the West of Ireland.

Methods

Postmortem reports between January 2006 and May 2012 detailed 153 individuals who died by probable suicide, 58 of whom attended the mental health services. Relevant socio-demographic and clinical data was extracted from individuals’ lifetime case notes.

Results

Recurrent depressive disorder (44%) was the most common diagnosis and hanging the most common method of death (58%). Of individuals who died by hanging, 79% previously attempted suicide by the same method. For individuals with a documented history of depression, only 32% had antidepressants detected in their toxicology reports. Similarly, only one individual (20%) with schizophrenia had antipsychotics detected in their toxicology report.

Conclusions

Individuals who died by probable suicide, most commonly died by hanging and drowning; with previous attempts of hanging particularly prevalent in the group who subsequently died by hanging. At the time of death, less than one-third of individuals according to toxicology reports were taking the medication that was last prescribed to them by the mental health services suggesting a high rate of treatment non-concordance in individuals who died by probable suicide.

Depressed mood and cause-specific mortality: a 40-year general community assessment

PURPOSE

The current study describes how the excess mortality risk associated with depression translates into specific causes of death occurring during a 40-year follow-up period, with focus on deaths related to injuries, cardiovascular diseases, and cancer.

METHODS

Data come from a cross-sectional survey (Community Mental Health Epidemiology Study) conducted in the early 1970s in Washington County, Maryland. Random sampling for the survey resulted in 2762 interviews. For the current analyses, baseline depressed mood was linked to current participant vital status through the use of death certificates.

RESULTS

The relative subdistribution hazards for cardiovascular deaths (3.08 [1.74-5.45]) and fatal injuries (4.63 [1.76-12.18]) were significant during the entire 40-year period for young adults (18-39 years old at baseline). The relative subdistribution hazard for cardiovascular deaths during the first 15 years of follow-up was pronounced in elderly (≥ 65 years) males (2.99 [1.67-5.37]) subjects. There were no significant associations between depressed mood and cancer deaths.

CONCLUSIONS

Individuals in the general community with depressed mood may be at increased risk of deaths as the result of cardiovascular disease and injury, even several decades after exposure assessment. Young adults with depressed mood appear to be particularly vulnerable to these associations.

Suicidality in people taking antiepileptic drugs: What is the evidence?

Suicide is an important cause of premature death. In the general population, most people who commit suicide have a psychiatric problem at the time. People with epilepsy are thought to be at increased risk from suicide and suicidality (suicidal ideation or behaviour). Standardized mortality ratios estimated for suicide in people with epilepsy are usually between 3 and 5. Risk factors for suicide in people with epilepsy have been suggested, including early age of onset of seizures, temporal lobe epilepsy, severe seizures and recent control of seizures. Psychiatric co-morbidity also seems to be an important factor in people with epilepsy who commit suicide. In recent years, suicidality has been recognized as a complication of several groups of drugs and, most recently, antiepileptic drugs (AEDs) have been implicated. The US FDA performed a meta-analysis of 199 placebo-controlled studies of 11 AEDs used for seizure control, psychiatric or 'other' indications. There were four completed suicides in those taking AEDs and none in those taking placebo. The odds ratio for suicidal behaviour or ideation was 1.8 (95% CI 1.24, 2.66), suggesting that people taking AEDs are more at risk than those taking placebo. The odds ratio was significantly raised for people taking AEDs for epilepsy, but not for the other indications. AEDs may affect mood by means of several mechanisms. In people with epilepsy, however, the concept of forced normalization (or alternative psychosis) may also play a part. In this situation, control of seizures (by AEDs or epilepsy surgery) may alternate with psychotic features or, less commonly, depression, although this is not fully understood. The risk of suicidal ideation and behaviour as adverse effects of AED treatment, although increased, seems low. As a result of the FDA's alert clinicians are supposed to inform patients and their families of this increased risk but it is important to place it in a proper perspective. Some people with epilepsy are more likely to develop psychiatric adverse effects with any AEDs, and these people should be followed closely whenever a new AED is introduced. Nonetheless, in people with epilepsy the risk of suicidality associated with AEDs needs to be balanced against the risk of not treating the seizures. In fact, the risk of stopping AEDs or refusing to start AEDs for the control of a seizure disorder may be significantly worse and may result in serious harm, including death of the patient.
