Suicidal children grow up : rates and psychosocial risk factors for suicide attempts during follow-up

OBJECTIVE Rates and psychosocial risk factors for suicide attempts during a 6 to 8-year follow-up period were compared for 25 predominantly prepubertal inpatient suicide attempters, 28 inpatient suicidal ideators, 16 nonsuicidal inpatients, and 64 nonpatients. METHOD Standard research instruments were used to interview subjects and parents. Cox proportional hazard regression analyses were used to identify risk factors for a suicide attempt in the follow-up. RESULTS No deaths occurred during follow-up. Suicide attempters were six times and suicidal ideators were three times more likely than were nonpatients to attempt suicide during follow-up. Poor social adjustment and mood disorder close to a recurrent suicide attempt were the strongest risk factors. CONCLUSIONS Risk assessment should focus on identifying symptoms of mood disorders and impaired social adjustment in children with histories of suicide attempts and psychiatric hospitalization.

Suicidal Children Grow Up: Suicidal Behavior and Psychiatric Disorders among Relatives

OBJECTIVE This paper reports comprehensive data on psychiatric symptoms and disorders and medical problems of first- and second-degree biological relatives of prepubertal children who have contemplated or attempted suicide. METHOD Standard family study and family history interview techniques were used to obtain information about psychopathology and medical illness in 488 first- and 1,062 second-degree relatives of 25 child psychiatric inpatients who reported suicide attempts, 28 child psychiatric inpatients who contemplated suicide, 16 nonsuicidal child inpatients, and 54 normal children. RESULTS Suicidal behavior in children was associated with suicidal behavior in their families, although no first-degree relatives committed suicide. More first-degree relatives of child suicide attempters, compared to first-degree relatives of normal children, had antisocial personality disorder, assaultive behavior, and substance abuse. Mood disorders in first-degree relatives were not associated with child suicidal behavior. No significant associations were identified for psychopathology of second-degree relatives and child suicidal behavior. CONCLUSIONS The results suggest the importance of evaluating familial psychopathology during assessments of suicidal children. Self-directed and externally directed violence, antisocial personality disorder, and substance abuse of relatives of suicidal children should be studied to elucidate the etiology of youth suicidal behavior.

EEG theta activity and pain insensitivity in self-injurious borderline patients

The principal aim of this study was to investigate possible neurophysiological underpinnings of self-injurious behavior in women with borderline personality disorder (BPD). Pain report and EEG power spectrum density during a laboratory pain procedure, a 4-min 10 degrees C cold pressor test (CPT), were compared among four groups; female inpatients with BPD who do (BPD-P group, n = 22) and do not (BPD-NP group, n = 19) report pain during self-injury, female inpatients with major depression (n = 15), and normal women (n = 20). The BPD-NP group reported less pain intensity during the CPT compared to the other groups. Total absolute theta power was significantly higher in the BPD-NP group compared to the Depressed (P = 0.0074) and Normal (P = 0.0001) groups, with a trend toward being significantly higher compared to the BPD-P group (P = 0.0936). Dissociative Experience Scale scores were significantly higher in the BPD-NP group compared to the Depressed and Normal groups (maximum P = 0.0004), and significantly higher in the BPD-P group compared to the Normal group (P = 0.0016). Beck Depression Inventory and Sheehan Patient Rated Anxiety Scale scores were significantly lower in the Normal group compared to all patient groups. Theta activity was significantly correlated with pain rating (Pearson partial r = -0.43, P = 0.0001) and Dissociative Experiences Scale score (Pearson partial r = 0.32, P = 0.01).

Suicidal Children Grow Up: Suicidal Episodes and Effects of Treatment during Follow-up

OBJECTIVES This paper describes risk for first recurrent suicidal episodes in follow-up of suicidal child psychiatric inpatients. It identifies relations between suicide attempts in follow-up and psychosocial and psychopharmacological treatments. METHODS First suicidal episodes involving either suicidal ideation or a suicide attempt in a 6 to 8 year follow-up period were rated for 69 child psychiatric inpatients and 64 children selected from the community. Psychiatric treatments were determined from reports from multiple sources. RESULTS Forty-five percent of 133 subjects reported a suicidal episode during follow-up. Children who reported suicidal ideation or a suicide attempt were greater than twice as likely to report a suicidal episode in follow-up than were children from the community. Children treated with antidepressants in follow-up were more likely to attempt suicide than were those not treated with antidepressants. CONCLUSIONS Close follow-up of suicidal children is warranted to identity risk and to intervene to prevent suicidal episodes. Lack of efficacy of naturalistic treatments implies that controlled treatment studies are needed to determine effective intervention for suicidal children.

Personality Disorder Symptoms Predict Declines in Global Functioning and Quality of Life in Elderly Depressed Patients

The authors evaluated personality disorder symptoms as predictors of change in global functioning and quality of life among elderly depressed patients. Treated elderly patients (N=40) who no longer met RDC criteria for major depression were assessed for personality disorders, depression, global functioning, and quality of life after treatment of the acute episode and at 1-year follow-up. In interaction with persisting or recurrent depression, Cluster B personality disorder symptoms contributed to declines in global functioning and quality of life over a 1-year period. Personality disorder symptoms in elderly patients appear to operate as co-factors that amplify or exacerbate the impact of residual depression on long-term functioning and quality of life.

Treatment response of borderline inpatients : a growth curve analysis

This study examined the course of 40 hospitalized female borderline personality disorder patients over 25 weeks of inpatient treatment. Course was measured through weekly administration of the SCL-90-R. Level of identity and interpersonal problems, hypothesized by Kernberg to be at the center of the borderline patient’s pathology, were found to be powerful predictors of treatment course. Patients with the most severe identity and interpersonal problems reported more symptoms throughout treatment and increasing symptom levels over time. This was very different from patients with the lowest level of identity and interpersonal problems, who reported fewer symptoms overall and decreasing symptoms over time.

A prospective 5-year follow-up study on the behavioral disturbances of community-dwelling elderly people with Alzheimer disease.

The aim of the present study was to determine the longitudinal course of behavioral disturbances and to examine whether these disturbances are stage dependent during the course of Alzheimer disease (AD). One hundred seven community-dwelling patients with probable AD were assessed up to six times annually by using a validated and reliable rating scale, the Troublesome Behavior Scale, for assessing the frequencies of behavioral disturbances. The subjects were divided into three groups according to their baseline global function as assessed by the Clinical Dementia Rating (CDR; 1 = mild, 2 = moderate, 3 = severe). At the end of the 5-year observation period, 31 subjects were still active participants, 52 had died, 20 lived in institutions, and 4 had stopped participating. The patterns of their behavioral disturbance changes depended to a considerable extent on the baseline severity of the illness. The behavioral disturbance frequencies generally peaked at the CDR 2 stage and followed a downward trend thereafter. Considerable individual variations in the disturbance frequencies during the course of the illness were observed. Knowing the behavioral course of AD will enable clinicians to better counsel families and appraise the results of treatments for behavioral symptoms.

Impact of Depressive Symptoms on Conversion from Mild Cognitive Impairment Subtypes to Alzheimer’s Disease: A Community-Based Longitudinal Study

BACKGROUND While longitudinal studies have investigated the relationships between mild cognitive impairment (MCI) subtypes and dementia subtypes, the results have been contradictory. In addition, some research shows that depression accompanied by MCI might increase the risk of Alzheimers disease (AD). OBJECTIVE The aim of this study is to longitudinally investigate the relationships between MCI subtypes and dementia subtypes, with special attention to the effect of comorbid depressive symptoms in a Japanese rural community. METHODS Non-demented participants (n = 802) completed a baseline and follow-up study. Outcomes were conversion to dementia especially AD, MCI, or no conversion. A complementary log-log analysis was conducted to investigate the risk of dementia and AD in amnestic MCI (aMCI) compared to nonamnestic MCI (naMCI) groups. The impact of depressive symptoms on the transition from MCI to AD and from cognitively normal to MCI or AD was also analyzed. RESULTS The risk of developing dementia, in particular AD, for the aMCI group was significantly higher than that for the naMCI group. In the aMCI group, the presence of depressive symptoms increased the risk of developing AD, but depressive symptoms in the naMCI group did not. In the cognitively normal group, the presence of depressive symptoms increased the risk of aMCI but not naMCI or AD. CONCLUSION MCI subtyping could be useful in finding a prodrome for dementia and in particular for AD. The differing impacts of depressive symptoms on the development of AD suggest that the relationship between depressive symptoms and cognitive impairment could differ in aMCI and naMCI patients.
