OBJECTIVE: To examine the clinical symptoms and comorbid psychiatric disorders of depressed children and adolescents with and without clinically significant suicidal ideation. METHOD: Children and adolescents aged 7 to 17 years with current DSM-III-R major depressive disorder (MDD) (N = 135) were recruited between January 1987 and April 2002. Current MDD symptoms and lifetime comorbid psychiatric disorders were assessed using either a combination of the Schedule for Affective Disorders and Schizophrenia for School Age Children-Epidemiologic and -Present Episode versions or the -Present Lifetime version. Thirty-two percent (N = 43) of the depressed subjects were classified as suicidal (at least suicidal ideation with a plan). RESULTS: Depressed suicidal youth presented with a more severe episode (p = .001) and a poorer functional status (p = .019), were more hopeless (p = .001), and presented more frequently with insomnia (p = .011). There was an interaction between suicide x sex x pubertal status for severity of MDD (p = .013), the presence of hopelessness (p < .001), poor functional status (p = .023), and comorbidity with a lifetime history of any disruptive behavior (p = .019). Among pre-pubertal depressed males, suicidal boys had significantly increased severity of MDD (p = .025) and poorer functional status (p = .044) than non-suicidal boys. Among postpubertal depressed females, suicidal girls were more frequently hopeless (p = .008) and presented an increased severity of MDD (p = .022) and more frequent lifetime history of any disruptive behavior (p = .03) when compared with nonsuicidal girls. CONCLUSION: There appears to be a sex difference for some clinical features, particularly hopelessness, among depressed suicidal children and adolescents. Whether hopelessness is a sex-specific characteristic of depressed suicidal children and adolescents requires further study.  相似文献

BACKGROUND: The familial nature of early-onset major depressive disorder (MDD) has been documented in numerous family studies of adults and is supported by studies of offspring of parents with MDD, for whom the risk is more than 3-fold. None of the published high-risk studies have gone beyond 2 generations, and few have a longitudinal design. We report results of an approximately 20-year follow-up of families at high and low risk for depression. The first 2 generations were interviewed 4 times during this period. The offspring from the second generation are now adults and have children of their own, the third generation of the original cohort. OBJECTIVE: To examine the familial aggregation of psychiatric disorders and functioning in grandchildren by their parents' and grandparents' depression status. DESIGN: Longitudinal, retrospective cohort, family study. PARTICIPANTS: One hundred sixty-one grandchildren and their parents and grandparents. MAIN OUTCOME MEASURES: Lifetime rate of psychiatric disorder and functioning in grandchildren, stratified by parental and by grandparental depression status, collected by clinicians blind to diagnoses of previous generations and to previous interviews. RESULTS: There were high rates of psychiatric disorders, particularly anxiety disorders, in the grandchildren with 2 generations of major depression, with 59.2% of these grandchildren (mean age, 12 years) already having a psychiatric disorder. The effect of parental depression on grandchildren's outcomes differed significantly with grandparental depression status. Among families with a depressed grandparent, increased risk of anxiety (relative risk, 5.17; 95% confidence interval, 1.4-18.7; P = .01) and increased risk of any disorder (relative risk, 5.52; 95% confidence interval, 2.0-15.4; P = .002) were observed in grandchildren with a depressed parent as compared with those with nondepressed parents. The severity of parental depression, as measured by impairment, significantly increased the rate of a mood disorder in these grandchildren (relative risk, 2.44; 95% confidence interval, 1.1-5.5; P = .03). In contrast, among grandchildren with nonfamilial depression, ie, depressed parents with no depressed grandparents, there was no significant effect of parental MDD on grandchildren diagnoses. However, parental MDD, regardless of whether families had a depressed grandparent, had a significant impact on the grandchildren's overall functioning. Potential confounding variables did not affect the strength of the association with parental and grandparental depression. CONCLUSIONS: The association between parental MDD and child diagnosis is moderated by grandparental MDD status. The rates of psychopathology are highest in grandchildren of parents and grandparents with a moderately to severely impairing depression. Anxiety disorders are the early sign of psychopathology in the young grandchildren. Early interventions in the offspring of 2 generations affected with moderately to severely impairing MDD seem warranted. This familial group may be the target for neuroimaging, genetic, and other biological studies.  相似文献

OBJECTIVE: High-risk studies of psychiatric disorders in parents and offspring that include 3 generations are uncommon. Multigenerational studies can be clinically useful as they can provide information for risk prediction from one generation to another for the development of empirically based interventions. Using a high-risk design, this study examines the association of grandparent major depressive disorder (MDD) and parent MDD with psychopathology in grandchildren. METHOD: Using Cox proportional hazards in a sample of 90 grandchildren at high and low risk for depression by virtue of their grandparents' and parents' depression status, the authors examined the risk for offspring depression and anxiety. RESULTS: Grandparent and parent MDD were associated with grandchild anxiety (relative risk [RR] = 5.51 and R = 3.09, respectively). Grandchildren with both a depressed parent and grandparent had the highest risk for anxiety. Parental MDD is associated with an increased risk for grandchild disruptive disorder (RR = 10.77). Forty-nine percent of the grandchildren in families in which both the parent and grandparent were depressed had some form of psychopathology. The grandchildren from those families were the most impaired. CONCLUSIONS: Prepubertal-onset anxiety disorder is a risk factor for the later development of clinically significant recurrent MDD across several generations of families at high risk for depression. Parental impaired functioning increases the risk for disruptive disorders. Children in families with multiple generations of depression are at particularly high risk for some form of psychopathology.  相似文献

OBJECTIVE: To examine various forms of suicidality specified in DSM-IV and their clinical characteristics in a large sample of children and adolescents with major depressive disorder (MDD). METHOD: Subjects included 553 children and adolescents (aged 7.0-14.9 years) recruited between April 2000 and December 2004 from 23 mental health facilities in Hungary. Subjects received standardized clinical evaluations and best-estimate consensus DSM-IV diagnoses of MDD. All subjects were in a current episode of MDD at their assessment date. RESULTS: Approximately 68% of the sample had recurrent thoughts of death, 48% had suicidal ideation, 30% had suicide plan, and 12% had attempted suicide. Compared with nonsuicidal peers, suicidal children and adolescents were more severely depressed, had more depressive symptoms, and more likely had comorbid disorders. However, depressed children and adolescents with various forms of suicidality were very similar in clinical characteristics. Feelings of worthlessness, depressed mood, psychomotor agitation, and comorbid separation anxiety and conduct disorders were independent correlates of at least 1 form of suicidality. Only feelings of worthlessness was related to all 4 suicidal behaviors, after adjustment for other depressive symptoms, comorbid disorders, and demographics. CONCLUSION: Clinical characteristics differ between nonsuicidal and suicidal children and adolescents but are very similar across various forms of suicidality. Feelings of worthlessness may play a central role in the development of suicidal behavior. Interventions toward the enhancement of self-esteem and amelioration of underlying psychopathology may be crucial for the prevention of suicide attempts in depressed children and adolescents.  相似文献

Numerous studies have demonstrated that low birth weight (LBW) is associated with the development of medical conditions, such as hypertension and diabetes, and psychiatric disorders, such as depression. One possible mechanism through which LBW might increase risk for both medical and psychiatric disorders is by altering the biologic systems (such as the hypothalamic-pituitary-adrenal [HPA] axis function) that govern emotion regulation and physical reactivity. In this study, we conducted secondary data analyses in a longitudinal study originally designed to understand the intergenerational transmission of major depressive disorder (MDD). We examined the risk for both medical and psychiatric illnesses known to be influenced by HPA axis dysregulation in the context of parental depression. The study had 2 primary objectives: (1) to examine whether LBW increases the risk of selected adult illness that may be influenced by the HPA axis and (2) to examine whether the increased risk of illness varies by parental depression status. We conducted longitudinal assessments of 244 offspring of depressed and nondepressed parents for more than 20 years. Psychopathology and medical illness were assessed by direct interview conducted by clinicians blind to risk status and previous diagnosis. We examined the effect of BW in 3 categories: less than 2.5 kg (LBW), 2.5-3.5 kg, and more than 3.5 kg (reference group). Offspring with LBW had a significantly increased risk of MDD, anxiety disorders, phobia, suicidal ideation, impaired functioning, allergies, and hypertension compared to those with BW exceeding 3.5 kg. The association between LBW and depression was stronger among children of depressed parents than among children of nondepressed parents, with an interaction term (BW and parental depression status) significant for MDD (P = .05), suggesting that parental depression may augment the impact of LBW on offspring depression:  相似文献

OBJECTIVE: To determine the independent effects of parental depression and family discord on psychopathology in offspring at high and low risk for major depression. METHOD: One hundred eighty-two offspring of depressed or nondepressed parents were followed over 10 years. In direct interviews, parents' and offspring's psychopathology was evaluated by raters blind to parents' clinical status. Five dimensions of family discord-poor marital adjustment, parent-child discord, low family cohesion, affectionless control, and parental divorce-were assessed. RESULTS: Offspring exposed to either parental depression or family discord had higher rates of psychopathology than their counterparts. High-risk offspring had few family discord measures associated with their psychopathology; in low-risk offspring, family discord was associated with all offspring diagnoses. Between the two risk factors, parental depression proved a more important predictor for offspring major depressive disorder (MDD) and anxiety disorder, whereas family discord was a more important predictor for substance use disorder. CONCLUSIONS: Parental depression is a strong and consistent risk factor for offspring MDD and anxiety disorder. Without parental depression, offspring have less exposure to family discord and lower rates of psychopathology. In the presence of family discord, rates of MDD, anxiety disorder and substance use disorder increased. When offspring matured into young adulthood, effects of parental depression and family discord persisted.  相似文献

Prolactin secretion in depressed children.   总被引:3,自引:0,他引:3  
BACKGROUND: Few studies have examined the involvement of the central dopaminergic system in the pathophysiology of mood disorders. The study of prolactin (PRL) secretion may be an informative indirect method for the assessment of the dopaminergic system in children with major depressive disorder (MDD). METHODS: Plasma PRL concentrations were measured at 20-min intervals over a 24-hr period in 40 pre-pubertal children with MDD, 18 with non-affective psychiatric disorders (PC), and 6 normal controls (NC). A subgroup of depressed children (n = 21) was restudied after recovery. RESULTS: There was no significant differences in either the amount or the pattern of PRL secretion between the MDD, PC, and NC groups. Children who recovered from their depression secreted less PRL during sleep and more while awake compared to when they were acutely depressed. CONCLUSIONS: Overall, there were no differences in baseline PRL secretion between children with MDD, NC and psychiatric control. These results suggest that the dopaminergic system as measured by baseline PRL blood levels is not compromised in children with MDD.  相似文献

BACKGROUND: Major depression (MDD) is heritable, and children of depressed parents are at higher risk for the development of depression. However, depression in a parent might also act as a stressor leading to increased activation of neuroendocrine stress circuits. To address this question we examined saliva cortisol in children whose parents have a history of MDD. METHODS: We recruited 15 families with one parent with MDD (26 prepubertal children) and 16 control families without history of parental MDD (32 prepubertal children). All parents and children underwent Structured Clinical Interview for DSM-IV and Kiddie Schedule For Affective Disorders And Schizophrenia interviews, respectively. Families were asked to collect morning, afternoon, and bedtime saliva samples for 4 days for 2 weeks. At bedtime of the 3rd day, dexamethasone was administered. Two doses, standard and low, were used in each family. RESULTS: The majority of children demonstrated no psychiatric diagnosis. Children with MDD parents showed higher cortisol basally and higher cortisol after both 25 mg and 5 mg dexamethasone. However, this effect occurred predominantly in children whose parents were currently depressed. There were strong correlations for cortisol between parents and children (r = 52 in depressed; r = 499 in control). CONCLUSIONS: Elevated cortisol and impaired feedback seemed to reflect an environmental effect of MDD in a parent.  相似文献

The increased risk of physical health problems in adult depressed patients has been shown in numerous studies. A recent study of the offspring of depressed parents found similar associations. The purpose of this study is to examine the strength and specificity of the association between depression and physical health problems in children and adolescents whose parents are dependent upon opiates. The sample consisted of offspring ages 6-17 (mean age 11 years) of opiate addicts who had a history of major depressive disorder (MDD; n = 28); other mood disorders (n = 31); no history of mood disorders but other psychiatric disorders (n = 92); or no history of psychiatric disorder (n = 127). Detailed psychiatric assessment and medical history of the offspring by direct interview with the offspring and an informant were obtained blind to parental diagnosis. After controlling for possible confounders, there was an increased risk of dermatological disorders, headache, other neurological/neuromuscular disorders, bronchitis, other respiratory disorders and hospitalizations for nonsurgical procedures in offspring with MDD, as compared to nonpsychiatrically ill controls. The offspring with other mood disorders had a slightly elevated risk. Major depression in children and adolescents whose parents are dependent on opiates is associated with increased risk of physical health problems. This finding is consistent with other reports and the timing of the physical health problems requires further study.  相似文献

Genetics of the serotonergic system in suicidal behavior   总被引:15,自引:0,他引:15  
Genetic factors contribute to the risk of psychopathology in many psychiatric conditions, but the specific genes are yet to be identified. Neurotransmitter alterations are implicated in the etiology of psychopathology based, in part, on studies of neurotransmitter receptors and their biosynthetic or degradative enzymes in postmortem tissue. Identification of the altered receptors and enzymes serves to identify candidate genes of potential etiological significance. Polymorphisms in these genes can contribute to alterations in protein function in vivo that are part of the neurochemical underpinnings of psychopathologies such as major depressive disorder, psychoses, alcoholism, personality disorders, aggressive-impulsive traits, or suicidal behavior. Altered serotonergic function is implicated in the etiology and pathogenesis of several major psychiatric conditions. In particular, there is much evidence for an association of lower serotonergic function and suicidal behavior. Thus genes related to the serotonergic system are candidate genes worthy of study as part of the genetic diathesis for suicidal behavior. This review examines the following polymorphisms in the serotonin biosynthetic enzyme tryptophan hydroxylase (TPH; A779C substitution), the serotonin transporter (5-HTT, 5-HTTLPR allele), the 5-HT(1B) receptor (G861C, C129T substitution) and the 5-HT(2A) receptor (T102C) for their relationship to suicidal behavior. For the TPH gene, we found the less common U or A allele variant of the A779C polymorphism was associated with suicide attempt. Other studies have found the U allele to be associated with aggression and lower serotonergic function in vivo. A 44 base pair insertion/deletion in the 5' flanking promoter region of the 5-HTT gene may result in less 5-HTT expression and 5-HTT binding. We examined 220 cases postmortem and found no association between the promoter genotype and 5-HTT binding. We also found no association with major depressive disorder (MDD), suicide or pathological aggression, despite finding significantly fewer 5-HTT sites in the prefrontal cortex of depressed and/or suicide cases. In genomic DNA samples from 178 unrelated subjects, we detected two polymorphisms for the 5-HT(1B) receptor at nucleotides 861 and 129. However, no association between either polymorphism and depression, suicide, aggression, or alcoholism was observed. There are two common polymorphisms for the 5-HT(2A) receptor gene in humans. The results of studies of 5-HT(2A) receptor gene polymorphisms do not indicate significant major associations with suicidal behavior. In contrast, the 5-HT(2A) receptor itself is reported to be increased in suicide. Functional polymorphisms involving the promoter region that affect gene expression may explain this finding. Studies of candidate genes related to serotonergic function in brain are increasingly used to establish genetic alterations contributing to psychiatric illness. The most meaningful studies combine the study of candidate genes with direct measures of related proteins as well as psychopathology.  相似文献

The authors conducted a study of 30 hospitalized children who were referred for psychiatric consultation and 60 hospitalized children who were not. They studied the medical charts of these children and administered a questionnaire including a checklist of behavioral symptoms to their parents. More psychopathology was found in the children referred for consultation, but about 20 percent of the children not referred also showed a high degree of psychopathology. Factors found to be associated with referral for psychiatric consultation were older age, longer hospital stay, many previous hospitalizations, and ambiguous diagnoses.  相似文献

OBJECTIVE: This aim of this study was to examine the influence of grandparental (G1) and parental (G2) major depressive disorder (MDD) and other forms of psychopathology on behavior problems in very young offspring (G3). METHOD: Oregon Adolescent Depression Project (OADP) participants who had children over a 3-year period were invited to participate in a study of infant and child development. We attempted to collect diagnostic history from the original OADP (G2) participants, their coparents, the parents of the original OADP participants (G1), and the parents of the coparents. Child (G3) outcomes at 24 months of age were based on parent reports of behavior problems. RESULTS: Univariate correlations indicated that G1 and G2 familial loadings for MDD were associated with higher levels of G3 internalizing and externalizing behavior problems. Multiple regression analyses revealed a significant interaction between G1 and G2 MDD on G3 internalizing (but not externalizing) behavior problems. A higher familial loading for MDD in either the parental or grandparental generation was associated with elevated grandchild internalizing problems, but higher loadings for MDD in both generations did not convey additional risk. CONCLUSIONS: Parental MDD and grandparental MDD are both associated with elevated levels of internalizing problems in young grandchildren, but MDD in both the G1 and G2 generations does not confer additional risk. One important implication is that MDD in the grandparental generation is associated with increased risk to grandchildren even in the absence of parental MDD. Future studies should examine the mechanisms through which grandparental psychopathology influences behavior problems in grandchildren.  相似文献

Data are reported from psychiatric evaluations of a large group of communication disordered children and their parents who presented to a community speech clinic. Systematic psychiatric evaluations involving the use of standardized interviews, questionnaires, and DSM-III diagnostic criteria reveal that approximately 50% of the children have definable DSM-III psychiatric disorders and approximately the same percentage of children have at least one psychiatrically ill parent. Comparisons of children with psychiatrically ill parents and children with psychiatrically well parents show that parental psychiatric disorder is associated with increased psychopathology in the children. However, other factors, particularly psychosocial stress, are more strongly correlated with the presence of childhood psychopathology. There are few correlations between the types of parental psychiatric disorders and the types of childhood disorders.  相似文献

Abstract:  Globally, a million people commit suicide every year, and 10–20 million attempt it. Mood disorders, especially major depressive disorder (MDD) and bipolar disorder, are the most common psychiatric conditions associated with suicide. Primary (psychiatric and physical illness), secondary (psychosocial), and tertiary (demographic) risk factors for suicide have been identified. Comorbid psychiatric illness, particularly anxiety symptoms or disorders, significantly increase the risk of suicidal behavior. Current standard risk assessments and precautions may be of limited value, while assessing the severity of anxiety and agitation may be more effective in identifying patients at risk. Lithium is the medication that has most consistently demonstrated an antisuicidal effect. The effects of antidepressants and conventional antipsychotics on suicide risk are uncertain, but atypical antipsychotics appear promising. Atypical antipsychotics have beneficial effects on depressed mood both in patients with MDD and in patients with bipolar disorder. In addition, data in patients with schizophrenia have demonstrated a significant improvement in the incidence of suicidal behavior with clozapine compared with olanzapine. Electroconvulsive therapy appears to have an acute benefit on suicidality.  相似文献

A controlled family history study of prepubertal major depressive disorder   总被引:1,自引:0,他引:1  
First-degree (N = 195) and second-degree (N = 785) adult relatives of prepubertal children with major depression (N = 48), children with nonaffective psychiatric disorders (N = 20), and normal children (N = 27) were assessed by the Family History-Research Diagnostic Criteria method (FH-RDC), except for the adult informant (usually the mother), who was directly interviewed. Compared with normal controls, prepubertal children with major depressive disorder (MDD) had significantly higher familial rates of psychiatric disorders in both first- and second-degree relatives, especially MDD, alcoholism, and "other" (mostly anxiety) diagnoses. Relatives of children in the nonaffective psychiatric control (PC) group had low rates of alcoholism, high rates of other (anxiety) disorder diagnoses, and intermediate rates of MDD (accounted for by those children with separation anxiety). This suggests that prepubertal onset of major depression may be especially likely in families with a high aggregation of affective disorders when these families also have a high prevalence of alcoholism, and that a proportion of children without affective disorder but with separation anxiety disorder in this study were at high risk for the development of affective illness later in life. These results support the validity of prepubertal-onset depressive illness as a diagnostic category, and are consistent with high familial rates of MDD and other psychiatric disorders found in family studies of adolescent and early-onset adult probands with major affective disorders, and with studies of the offspring of parents with major affective disorders. Within the child MDD group substantial heterogeneity was found. Low familial rates of MDD were associated with suicidality and comorbid conduct disorder in the child probands. The highest familial rates of MDD, approximately threefold those in the normal controls, and all the bipolar relatives, were found in the families of prepubertal probands with MDD who never had a concrete suicidal plan or act and who were without comorbid conduct disorder. A useful nosological continuum in which to classify prepubertal MDD may be to place at one end those patients with comorbid conduct disorder and at the other end those patients with manifestations related to bipolarity, including hypomania, mania, and psychotic subtype.  相似文献

Evidence suggests a relationship between parental depression and phobias in offspring as well as links between childhood fears and risk for major depression. This study examines the relationship between major depressive disorder (MDD) and anxiety disorders in parents and specific fears and phobias in offspring. Three hundred and eighteen children of parents with lifetime MDD, anxiety disorder, MDD+anxiety disorder, or neither were psychiatrically assessed via parent interview. Rates of specific phobias in offspring did not differ significantly across parental groups. Specific fears were significantly elevated in offspring of parents with MDD+anxiety disorder relative to the other groups (MDD, anxiety disorder, and controls, which did not differ). We failed to find increased phobias in offspring of parents with MDD without anxiety disorder. Elevated rates of specific fears in offspring of parents with MDD+anxiety disorder may be a function of more severe parental psychopathology, increased genetic loading, or unmeasured environmental influences.  相似文献

Course and outcome of child and adolescent major depressive disorder   总被引:1,自引:0,他引:1  
Major depressive disorder (MDD) is a familial recurrent illness that significantly interferes with the child's normal development and is associated with increased risk for suicidal behaviors and psychiatric and psychosocial morbidity. Although most children and adolescents recover from their first depressive episode, 30-70%, in particular those with familial history of MDD, comorbid psychiatric disorders, dysthymia, subsyndromal symptoms of depression, anxiety, negative cognitive style, and exposure to negative life events (e.g., family conflicts and abuse) will experience one or more depressive recurrences during their childhood, adolescence, and adulthood. Depressed youth who present with psychosis, psychomotor retardation, pharmacological induced hypomania/mania, and/or family history of bipolar disorder are at high risk to develop bipolar disorder.  相似文献

BACKGROUND: Few studies have investigated risk factors for suicidal ideation and attempts, or possible variations in them, among representative samples of psychiatric patients with major depressive disorder. METHOD: As part of the Vantaa Depression Study in Vantaa, Finland, 269 patients with DSM-IV major depressive disorder (MDD), diagnosed by interview using semistructured World Health Organization Schedules for Clinical Assessment in Neuropsychiatry, version 2.0, and Structured Clinical Interview for DSM-III-R Personality Disorders, were thoroughly investigated. Information was gathered on patients' levels of depression, anxiety, hopelessness, perceived social support, social and occupational functioning, and alcohol use. Suicidal behavior was assessed by interviews, including the Scale for Suicidal Ideation, and by information from psychiatric records. Data were gathered from Feb. 1, 1997, to May 31, 1998. RESULTS: During the current MDD episode, 58% of all patients had experienced suicidal ideation; among the 15% of the total who had attempted suicide, almost all (95%) had also had suicidal ideation. In nominal regression models predicting suicidal ideation, hopelessness, alcohol dependence or abuse, low level of social and occupational functioning, and poor perceived social support were found to be significant (p < .05) independent risk factors. High severity of depression and current alcohol dependence or abuse in particular, but also younger age and low level of social and occupational functioning, predicted suicide attempt. CONCLUSION: Suicidal ideation is prevalent and appears to be a precondition for suicide attempts among psychiatric patients with MDD. The risk factors for suicidal ideation and attempts locate in several clinical and psychosocial domains. While these risk factors largely overlap, the overall level of psychopathology of suicide attempters is higher compared with that in patients with ideation, and substance use disorders and severity of depression may be of particular importance in predicting suicide attempts.  相似文献

Suicidal fantasies in normal children   总被引:1,自引:0,他引:1  
This study of a randomly selected sample of 101 schoolchildren, who had no history of previous psychiatric symptomatology, showed that approximately 12% of the children had suicidal impulses. Verbatim statements of the children about their suicidal tendencies are presented. Case vignettes illustrate the common occurrence of parental depression and suicidal behavior and the child's identification with these depressed parents. Clinical implications of these findings are discussed.  相似文献
