Increased suicide risk and clinical correlates of suicide among patients with Parkinson's disease

IntroductionParkinson's disease (PD) is a debilitating, neurodegenerative condition frequently complicated by psychiatric symptoms. Patients with PD may be at higher risk for suicide than the general population, but previous estimates are limited and conflicting. The aim of this study is to estimate the suicide rate based on the clinical case registry and to identify risk factors for suicide among patients diagnosed with PD.MethodsThe target sample consisted of 4362 patients diagnosed with PD who were evaluated at a general hospital in Seoul, South Korea, from 1996 to 2012. The standardized mortality ratio for suicide among PD patients was estimated. In order to identify the clinical correlates of suicide, case-control study was conducted based on retrospective chart review. The 29 suicide cases (age: 62.3 ± 13.7 years; females: 34.5%) were matched with 116 non-suicide controls (age: 63.5 ± 9.2 years; females 56.9%) by the year of initial PD evaluation.ResultsThe SMR for suicide in PD patients was 1.99 (95% CI 1.33–2.85). Mean duration from time of initial diagnosis to suicide among cases was 6.1 ± 3.5 years. Case-control analysis revealed that male, initial extremity of motor symptom onset, history of depressive disorder, delusion, any psychiatric disorder, and higher L-dopa dosage were significantly associated with suicide among PD patients. Other PD-related variables such as UPDRS motor score were not significantly associated with death by suicide.ConclusionSuicide risk in PD patients is approximately 2 times higher than that in the general population. Psychiatric disorders, and also L-dopa medication need further attention with respect to suicide.     

Risk factors for suicide among patients with schizophrenia

In order to assess risk factors for suicide among patients with schizophrenia, we compared 32 patients with schizophrenia who committed suicide during an 11 year follow-up with a control group of 64 schizophrenics who did not commit suicide. A history of previous suicide attempts was the factor most strongly related to suicide. In females we found an increased risk for suicide among unmarried, divorced or widowed and among those living alone. In males we found an increased risk among those with a history of alcohol abuse. In contrast to findings in other studies, distribution of age and sex and a history of depressive episodes were factors not associated with an increased risk for suicide. We conclude that suicidal acts among schizophrenics are often impulsive and difficult to predict. Traditional risk scales are of limited value in the clinical assessment of suicidal risk.     

Temperaments mediate suicide risk and psychopathology among patients with bipolar disorders

BackgroundSeveral studies have demonstrated that bipolar II (BD-II) disorder represents a quite common, distinct form of major mood disorders that should be separated from bipolar I (BD-I) disorder. The aims of this cross-sectional study were to assess temperament and clinical differences between patients with BD-I and BD-II disorders and to assess whether temperament traits are good predictors of hopelessness in patients with bipolar disorder, a variable highly associated with suicidal behavior and ideation.MethodParticipants were 216 consecutive inpatients (97 men and 119 women) with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR), BD who were admitted to the Sant'Andrea Hospital's psychiatric ward in Rome (Italy). Patients completed the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego—Autoquestionnaire, the Beck Hopelessness Scale (BHS), the Mini International Neuropsychiatric Interview (MINI), and the Gotland Scale of Male Depression.ResultsPatients with BD-II had higher scores on the BHS (9.78 ± 5.37 vs 6.87 ± 4.69; t_143.59 = ?3.94; P < .001) than patients with BD-I. Hopelessness was associated with the individual pattern of temperament traits (ie, the relative balance of hyperthymic vs cyclothymic-irritable-anxious-dysthmic). Furthermore, patients with higher hopelessness (compared with those with lower levels of hopelessness) reported more frequently moderate to severe depression (87.1% vs 38.9%; P < .001) and higher MINI suicidal risk.ConclusionTemperaments are important predictors both of suicide risk and psychopathology and may be used in clinical practice for better delivery of appropriate care to patients with bipolar disorders.     

Proximal risk factors and suicide methods among suicide completers from national suicide mortality data 2004-2006 in Korea

This study was conducted to examine differences in proximal risk factors and suicide methods by sex and age in the national suicide mortality data in Korea. Data were collected from the National Police Agency and the National Statistical Office of Korea on suicide completers from 2004 to 2006. The 31?711 suicide case records were used to analyze suicide rates, methods, and proximal risk factors by sex and age. Suicide rate increased with age, especially in men. The most common proximal risk factor for suicide was medical illness in both sexes. The most common proximal risk factor for subjects younger than 30 years was found to be a conflict in relationships with family members, partner, or friends. Medical illness was found to increase in prevalence as a risk factor with age. Hanging/Suffocation was the most common suicide method used by both sexes. The use of drug/pesticide poisoning to suicide increased with age. A fall from height or hanging/suffocation was more popular in the younger age groups. Because proximal risk factors and suicide methods varied with sex and age, different suicide prevention measures are required after consideration of both of these parameters.     

Elevated suicide risk among patients with multiple sclerosis in Sweden

Results from previous studies of suicide risk among patients with multiple sclerosis (MS) are inconsistent. This may be explained partly by differences in methodology and study populations. The purpose of our study was to investigate suicide risk among hospital patients with MS in Sweden. During the period 1969-1996, 12,834 cases were recorded in the Swedish Hospital Inpatient Register, with 77,377 hospital admissions, in which MS was a primary or secondary diagnosis at discharge. The mean follow-up time for the whole cohort was 9.9 (SD 7.3) years. When the data for these MS patients were linked to the Swedish Causes of Death Register for the same period, 5,052 (39.4%) were found to have died. Among the 5,052 deaths, suicide was an underlying cause of death in 90 cases (1.8%). The mean period between the initial admission date with an MS diagnosis at discharge and the date of death for the 90 MS suicide cases was 5.8 (SD 5.1) years. This was significantly shorter (p = 0.002) than the mean of 7.9 (SD 6.4) years for MS cases who died due to other causes. Suicide risk, calculated as the standardized mortality ratio (SMR), was significantly elevated (SMR = 2.3) among both male and female MS cases compared with the general population. Suicide risk was particularly high in the first year after initial admission with an MS diagnosis, and among younger male MS cases. The mean age at the time of suicide was 44.5 (SD 12.4) years, and 58% of the suicides were committed within 5 years after the first admission with an MS diagnosis. The crude suicide rate among MS patients during the study period was 71 per 100,000 person-years. The rate was significantly higher (p < 0.001) in males (114) than in females (47), with an odds ratio of 2.4 (95% CI: 1.6-3.8). These findings have implications for suicide preventive measures in neurological practice.     

Increased rate of suicide among patients with Huntington''s disease.

The proportion of deaths attributed to suicide was examined among 506 deceased individuals with diagnosed or suspected Huntington's Disease from New England USA. Comparison of this proportion with that of the general population indicated that the odds of a death being due to suicide in the Huntington's disease group is 8.2 times that of the Massachusetts population for persons aged 50 to 69 yr, but no difference appears in the 10 to 49 yr age group. Among the 157 Huntington's disease patients for whom cause of death was known, the corresponding odds estimates are 23.0 for the 50 to 69 yr age group and 2.7 for the 10 to 49 yr age group. More than half of the suicides occurred in individuals who showed early signs of the illness but who had not been diagnosed, suggesting that suicide may occur more frequently in the early stages of the illness.     

Predictors of serious suicide attempts among patients with panic disorder

Of 74 panic disorder subjects followed up after 7 years, five reported serious suicide attempts and three had completed suicide. Compared with subjects who had not made serious attempts, the serious suicide attempters (including the three suicides) were younger, and fewer of them were married. Also, the serious attempt group had an earlier, more gradual onset of illness. More of the serious attempters had personality disorders and coexisting major depression. At the time of original assessment, the serious attempters had more severe symptoms. These data suggest that among patients with panic disorder, serious suicidal behavior is associated with more severe psychopathology.

Excess suicide among formerly hospitalized child psychiatry patients

The authors report suicide risk among 1331 child psychiatry inpatients followed up for 4 to 15 years in a record-linkage study. Age- and sex-matched comparisons were made with the general population of Iowa (the state from which most of the subjects were selected). Suicide rates were higher than expected for both sexes, but the excess (9 suicides) was significant only for males. No suicides occurred earlier than age 17. The risk of suicide was 80 times that expected for schizophrenic patients and 25 times that expected for patients with organic mental disorders. Unlike follow-up studies of adult inpatients, a significant excess of suicide was not associated with affective disorder, substance abuse, neurosis, or anorexia nervosa. Clinical variables indicating more complicated psychiatric disturbance were associated with an even greater rate of suicide; these variables included multiple hospitalizations, a hospital stay of more than 15 days, and the presence of a medical diagnosis.     

Death and suicide among former child and adolescent psychiatric patients

Background

Postnatal depression has received considerable research and clinical attention, however anxiety and stress in the postpartum has been relatively ignored. Along with the widespread use of the Edinburgh Postnatal Depression Scale (EPDS), depression has become the marker for postnatal maladjustment. Symptoms of anxiety tend to be subsumed within diagnoses of depression, which can result in anxiety being minimized or overlooked in the absence of depression. Some researchers have identified the need to distinguish between postnatal depression and anxiety, and to discern cases where depression and anxiety co-exist. The aim of this study was to assess the prevalence of postnatal distress using the EPDS and the Depression Anxiety Stress Scales (DASS-21).

Method

As part of a larger cross-sectional study, the EPDS and DASS-21 were administered to a convenience sample of 325 primiparous mothers, who ranged in age from 18 to 44 years (M = 32 years). Recruited through mother's groups and health centres in Melbourne Australia, inclusion was limited to mothers whose babies were aged between 6 weeks and 6 months. Analyses included comparisons between the classifications of women according to the EPDS and the DASS-21, and an exploration of the extent to which the EPDS identified anxious-depressed women.

Results

The EPDS identified 80 women (25%) as possibly depressed (using a cut-off of over 9), of which the DASS-21 corroborated 58%. In the total sample, 61 women (19%) were classified by the DASS-21 to be depressed. Using broader criteria for distress, it was revealed by the DASS-21 that a further 33 women (10%) showed symptoms of anxiety and stress without depression. A total of 41 women (13%) had symptoms of anxiety either in isolation or in combination with depression. The DASS-21 identified 7% of the sample as being both anxious and depressed. This at-risk sub-group had higher mean EPDS and DASS-depression scores than their depressed-only counterparts.

Conclusion

The prevalence of anxiety and stress in the present study points to the importance of assessing postnatal women for broader indicators of psychological morbidity than that of depression alone. The DASS-21 appears to be a useful instrument for this purpose.     

Where schizophrenic patients commit suicide: a review of suicide among inpatients and former inpatients

OBJECTIVE: To review the literature on suicide of inpatients with schizophrenia, to identify suicide risk factors as well as typical patterns of behavior and to suggest a rationale and strategies for future interventions. METHOD: A computerized MedLine, Excerpta Medica and PsycLit search supplemented by an examination of cross-references and reviews. RESULTS: Up to half the suicides among patients with schizophrenia occur during inpatient admission. Inpatient suicides were found among those of a young age group who were predominantly single, childless and socially isolated. The vast majority experienced an illness characterized by long duration and prolonged psychiatric hospitalizations or multiple admissions and discharges. Up to 50% of the suicides occurred in the first few weeks and months following discharge from the hospital. The paranoid subtype of schizophrenia, where positive symptoms prevail and negative symptoms are few, is associated with a suicide risk that is three times greater than that associated with nonparanoid subtypes and eight times greater than the risk associated with the deficit subtype. CONCLUSIONS: Treatment of suicide is a major problem among inpatients with schizophrenia. Evidence suggests that suicide is generally carried-out by patients who have been recently discharged or by those who manage to get away from the hospital. Strategies aimed at preventing this phenomenon have been introduced to the medical personnel, but suicide in these patients does not seem to have been reduced. We emphasize the need to establish guidelines for the prevention of suicide in hospitalized patients with schizophrenia.     

Attitudes towards suicide and suicidal patients among medical students.

Medical students' attitudes towards suicide and suicidal patients were studied. The aim was also to determine whether attitudes differ between students in the beginning and end of studies. A questionnaire including own attitudes on death and suicide and psychosocial circumstances was filled in by 63% of first and final year students (306 of 485). The calculation included a factor analysis on items describing the attitudes to suicidal patients. Attitudes towards patients became influenced by the knowledge of mental disorders and by biological aspects of behaviour during the education. Final year students more often consider suicide to be an expression of psychiatric disease and thought that people trying to commit suicide were not responsible for their own actions. Thirty-four percent and 44% (ns) in the first and last years, respectively, reported suicidal ideas some time in their lives. Students with such a history of suicide thoughts were less optimistic about the possibility to help. Ongoing depressive/anxious symptoms were prevalent in 36/305 (12%) of students, but did not seem to affect their attitudes to patients. Female students had sought psychological/psychiatric help more often than males (26% and 10%, P < 0.01).     

Differential medication adherence among patients with schizophrenia and comorbid diabetes and hypertension

OBJECTIVES: Global patient characteristics may affect adherence across all medications in a regimen, making medication-specific risk factors for adherence problems less important. Medication adherence was examined among patients with schizophrenia and comorbid physical conditions for consistency across therapeutic classes. METHODS: A national sample of veterans was selected according to use of medication for schizophrenia, diabetes, and hypertension (N=1,686). Adherence to each medication type was assessed with medication possession ratios (MPRs). Multilevel logistic models were used to study the impact of medication type on adherence, as well as the effect of other medication characteristics (such as the average days of medication supplied per refill), health service use, and patients' sociodemographic characteristics. RESULTS: Adherence was only modestly correlated across types of medication. Information about antipsychotic adherence explained only 13% and 16% of the variance in patients' antihypertensive and hypoglycemic MPRs, respectively. In unadjusted analyses, patients were more likely to have poorer adherence (MPR less than .8) to their antipsychotics (35%) than to their hypoglycemic (29%) or antihypertensive medications (26%) (p<.001). However, when analyses controlled for the average days' supply and other regimen characteristics, hypoglycemic and antihypertensive medications were associated with an increased risk of poor adherence relative to antipsychotics (both adjusted odds ratios=1.5, p<.001). CONCLUSIONS: Patients with schizophrenia and comorbid physical conditions demonstrated important differences in adherence across medications in their regimen, reinforcing the importance of medication-specific factors in determining adherence behavior. The lower levels of adherence observed for antipsychotics may be associated with the shorter refill intervals for these medications.     

Circumstances of suicide among individuals with schizophrenia

Very little is known about the circumstances surrounding suicides in people with schizophrenia. Between September 1989 and August 1998, 15 and 100 suicide victims with and without schizophrenia, respectively, were examined from the Maryland Brain Collection (MBC). Next-of-kin interview and medical record review following death collected demographic and clinical characteristics, family history, psychiatric symptoms, and variables surrounding the suicide. Individuals with schizophrenia exhibited significantly more lifetime depressive symptoms than those without schizophrenia. Jumping from a height was the most frequently used method among people with schizophrenia (40%), whereas gunshot wounds were most common among persons without schizophrenia (37%). A trend was noted for a smaller proportion of those with schizophrenia (20%) to plan the suicide, compared to 47% of those without the disorder. Suicide in schizophrenia is a significant clinical problem; thus, prior suicidal activity and depressive symptoms should be addressed because opportunities to intervene immediately before the act are limited.
