A family study of familial positive vs. familial negative alcoholics

Of 259 alcoholics studied, 173 were primary alcoholics. Familial positive primary alcoholics tended to have earlier onset of alcoholism and males seemed to have more complications from drinking. Family study data indicated that the familial positive group had family pedigrees more likely to contain relatives with antisocial personality disorder. This relationship to antisocial personality may help in explaining previous research findings in familial positive alcoholics.     

Patterns of familial alcoholism, alcoholism severity, and psychopathology

The interrelationships among the severity of alcoholism, psychopathology/personality, and the degree of familial alcoholism were examined using the following four familial alcoholism classification schemes, which each differentiated three degrees of familial alcoholism: 1) conventional, compared alcoholics with no, nonparental, and parental alcoholic relatives; 2) lineality, distinguished between subgroups with alcoholism in neither, one, or both sides of their family; 3) generational, compared alcoholics having no, one, or two generations of familial alcoholism; 4) quantitative, credited one point for each first-degree and 1/2 point for each second-degree alcoholic relative. The subjects were 83 male alcoholic Veterans Administration inpatients 50 years of age or under. The Alcohol Use Inventory, various alcohol-related symptoms and behaviors, and laboratory values were used to evaluate the severity/pattern of alcoholism. Psychopathology/personality were measured by the MMPI, the Psychopathic State Inventory, the MacAndrew Alcoholism Scale, the Childhood Problem Behaviors Questionnaire, and the percentage of patients with an antisocial personality disorder (ASP) diagnosis. Surprisingly few subgroup differences were revealed in the severity/pattern of alcoholism. Only age at time of treatment and use of nonalcoholic drugs were associated with increasing familial alcoholism. On the other hand, childhood behavior problems, particularly antisocial behavior, and an ASP diagnosis were found to be associated with an increasing degree of familial alcoholism. The diagnosis of ASP was most apparent in the two-generational and bilineal alcoholics, while an increased degree of familial alcoholism was not associated with ASP for the conventional classification. Bilineal familial alcoholics also exhibited an MMPI profile reflective of a characterological disorder.(ABSTRACT TRUNCATED AT 250 WORDS)     

Female alcoholics. V: The relationship between family history of alcoholism and outcome 3-10 years after treatment

In a long-term follow-up study of 44 female alcoholics, a family history of alcoholism was related to younger age of onset of problem drinking, but did not necessarily imply a poorer outcome within this highly selected group of individuals. Alcoholism in father and his family was not related to either antisocial or borderline personality disorder nor outcome. However, alcoholism in mother and her family correlated with both borderline personality disorder and a significantly poorer outcome. The findings are discussed within different frames of reference, considering genetic mechanisms, psychodynamic factors and family systems theory.     

Implications of family history of alcoholism, antisocial personality, and sex differences in alcohol dependence

In this study of 210 male and female alcoholic inpatients, significant associations were found 1) between antisocial personality diagnosis and early onset of all stages in alcohol dependence; 2) between bilineal family history of alcoholism and greater frequency of the consequences of impaired control, withdrawal symptoms, and the pathologic symptoms associated with chronic alcoholism; and 3) between being female and older at onset of the initial, but not final, stages of alcoholism and having more symptoms associated with chronic alcohol use. Antisocial personality, type of family history, and sex of the proband were not interactive but contributed separate additive effects.     

Association of alcoholism with antisocial personality in urban men

The association of alcoholism with antisocial personality is important from a research and a therapeutic standpoint. In a sample of urban black men, it was found that those with antisocial personality had a higher rate of alcoholism than those without. In addition, a family history of problem drinking, low educational level, and excessive irritability were also closely associated with alcoholism. The clinical, genetic, and neurophysiological implications of these findings are discussed.     

Psychiatric heterogeneity in antisocial alcoholics: relation to familial alcoholism.

There is some indication that addicts who qualify for a diagnosis of antisocial personality disorder (ASP) do not comprise a homogeneous group with respect to psychopathology. This preliminary study attempted to determine the extent to which DSM-III diagnosed ASP alcoholics with alcoholism on both sides of their family could be differentiated with respect to childhood behavioral problems and additional adult psychopathology from ASP alcoholics with low degrees of familial alcoholism. Two groups of ASP alcoholic patients were compared: (1) 11 high familial (bilineal) alcoholics, and (2) 22 low familial (nonfamilial or unilineal) alcoholics. Few group differences were found in sociodemographic or alcohol-related characteristics, although the high familial group tended to be younger. However, the high familial alcoholism group tended to report more childhood antisocial behaviors and more childhood behavior problems overall. The high familial alcoholism group also reported more psychopathology on three of the 10 Minnesota Multiphasic Personality Inventory (MMPI) clinical scales, paranoia (P less than .05), schizophrenia (P less than .06), and masculine-feminine (P less than .025). Effect sizes for these three variables were in the moderate range. The group MMPI profile of the high familial alcoholism group was indicative of serious characterological disturbances, while that of the low familial alcoholism group was much more normal. The results of this preliminary study provided evidence suggesting that antisocial individuals with a high degree of familial alcoholism are more likely to manifest psychopathology than antisocial individuals with a lesser degree of familial alcoholism.     

Factors predicting the onset of adolescent drinking in families at high risk for developing alcoholism.

BACKGROUND: With a longitudinal prospective design, the purpose of this study was 1) to assess, with survival analysis, the age of onset of drinking in relation to family history of alcoholism; 2) to examine the importance of selected neurobiological and psychosocial risk factors in predicting the onset to drink; and 3) to determine if the age of onset of substance dependence problems differed by risk group status. METHODS: One hundred twenty-five children and adolescents were evaluated annually (N = 638 evaluations), providing up to seven annual waves of longitudinal data. Survival analyses were performed to determine the age of onset of regular drinking and the age of onset for substance abuse/dependence. The age of onset of regular drinking outcome was modeled using familial density of alcoholism and four factors, which included neurobiological indices of development (postural sway and P300), personality characteristics, academic achievement, self-esteem, and trait anxiety. RESULTS: High-risk children/adolescents showed a significantly earlier age of onset of drinking and an earlier age of onset for substance abuse problems. Familial density of alcoholism predicted an earlier onset of drinking, as did having deficits in reading achievement, reduced P300 (visual and auditory), and greater postural sway for age. Higher scores on the Extraversion scale of the Junior version of the Eysenck Personality Inventory also predicted an earlier onset of drinking. CONCLUSIONS: Familial density of alcoholism (number of alcoholic first- and second-degree relatives) is an important predictor of adolescent alcohol initiation. Evidence is presented suggesting that part of the familial/genetic variation in outcome may be due to neurobiological factors and temperament.     

Behavioral symptoms and psychiatric diagnoses among 162 children in nonalcoholic or alcoholic families

OBJECTIVE: People with alcoholic relatives have high rates of alcohol abuse and dependence as adults, but their patterns of problems earlier in life are less clear. Many studies have not controlled for parental disorders other than alcoholism or for parents' socioeconomic status and general life functioning. The authors' goal was to conduct a study controlling for such factors. METHOD: Personal structured interviews and a behavioral checklist were administered to the parents of 162 children 7 years old or older whose fathers had participated in the 15-year follow-up of 453 sons of alcoholics with no history of antisocial personality disorder and sons of nonalcoholic comparison subjects originally selected from a university population. RESULTS: There was no significant relationship between a family history of alcoholism and childhood diagnoses of conduct, oppositional, or attention deficit disorders or with behavioral checklist summary scores. However, children with alcoholic relatives apparently have a slightly higher risk for drug abuse or dependence than those without alcoholic relatives. CONCLUSIONS: Once familial antisocial disorders and familial socioeconomic status are controlled for, a family history of alcoholism does not appear to relate to childhood externalizing disorders.     

Anticipation of age at onset in familial multiple sclerosis

Background and objective: Anticipation of age at onset in the younger generations is a widely known characteristic of many diseases with genetic inheritance. This study was performed to assess whether there is anticipation of age at onset in younger generations of familial multiple sclerosis (MS) in a Spanish population and to compare clinical characteristics of familial and sporadic MS. Methods: We studied a cohort of 1110 patients diagnosed with MS and followed‐up in our MS Unit. Patients were considered as familial MS if they had in their family at least one relative of first or second degree diagnosed with MS. Otherwise, patients were considered to have sporadic MS. We compared the age at onset between relatives from different generations, and we also compared the age at onset of familial and sporadic MS. Results: A lower age at onset in the younger generations was found (median 22 years vs. 30 years, P < 0.001) and a significant lower age at onset of the disease in familial MS comparing to sporadic MS (median 25 years vs. 29 years, P = 0.042). Conclusions: There is an anticipation of the age at onset of MS in the younger generations of patients with familial MS. There is also a lower age at onset in familial versus sporadic MS.     

The A1 allele of the DRD2 gene (TaqI A polymorphisms) is associated with antisocial personality in a sample of alcohol-dependent patients.

BACKGROUND: Presence of A1 allele of the DRD2 gene has been associated with a predisposition for alcoholism although there are limited data about its phenotypic expression in alcoholism. OBJECTIVES: To determine the importance of the A1 allele in clinical variables of alcohol dependence. METHODOLOGY: A sample of 103 alcohol-dependent males was studied. All patients were recruited consecutively from the general hospital and community settings. The diagnostics were made with the structured clinical interview for DSM-III-R (SCID); and the International Personality Disorder Examination (IPDE). Diagnosis of family alcoholism was made by direct interview or with the Research Diagnostic Criteria-Family History (RDC-FH). The Addiction Severity Index (ASI) and the Severity of Alcohol Dependence Scale (SADS) were used to assess alcohol dependence severity. Genotyping was done by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) methods. RESULTS: Approximately 39% of the sample carried the A1 allele (A1+ group). This group had higher prevalences of antisocial personality disorder (60% vs. 15.9%); and alcoholism family history (72.5% vs. 52.4%). Also A1+ had early onset alcohol abuse and more drinking problems. The presence of A1+ was the main factor to explain the diagnosis of antisocial personality disorder, but the weight of this factor was not sufficient to explain the complications assessed by the ASI. CONCLUSIONS: Our results support the existence of an association between the A1 allele and factors resulting from dopaminergic deficiency, otherwise denominated reward deficiency syndrome.     

Comparative dexamethasone suppression test measurements in bulimia, depression and normal controls

Twenty bulimics, 20 depressives and 20 normal controls were studied using the Dexamethasone Suppression Test (DST) as defined by Carroll et al. Their past psychiatric and family histories were compared. We found that actively bulimic subjects had a rate of DST non-suppression of 20%, and that 20% of them had a past history of a major depressive disorder. Forty per cent had a history of alcoholism and/or antisocial personality in a first degree relative, but only 5% had a positive family history of affective disorder. These rates were significantly lower than those found in the depressed group except for the family history of alcoholism and/or antisocial personality for which there was no significant difference. We identified a subgroup of bulimic DST non-suppressors who, like patients with melancholia, were characterized by past history of major depressive illness and high rates of family history of affective disorder, alcoholism and/or antisocial personality in first degree relatives. This group responded to antidepressant medications in a manner similar to depressed patients.     

The clinical phenotype of familial and sporadic late onset Alzheimer's disease

BACKGROUND: Familial factors are clearly associated with an increased risk of developing late onset Alzheimer's disease (LOAD). However, there is emerging evidence to suggest that familial factors may also influence clinical phenotype. To date, most studies have focussed on familial influences upon age of onset or duration of illness and few studies have compared the frequency of non-cognitive symptoms between familial and sporadic LOAD. OBJECTIVE: To describe the clinical phenotype, with an emphasis on non-cognitive symptoms, of patients with LOAD and to explore familial differences. METHOD: 374 patients with LOAD were recruited from the community based Camberwell Dementia Case Register and a comparison made of the clinical phenotype of patients with and without a first degree family history of dementia. RESULTS: A first degree family history of dementia was found in 27% of fully ascertained cases. An earlier age of onset was found in familial cases (77.2 years compared to 78.3 years, p<0.05). However, no other differences in clinical phenotype, including the rate of cognitive decline, duration or the frequency of non-cognitive symptoms, were found between familial and sporadic cases. CONCLUSIONS: Apart from an earlier age of onset, patients with familial LOAD, as a group, do not have major differences in their clinical phenotype compared to patients with sporadic LOAD.     

A three-axes approach of subtyping the alcohol dependence syndrome

Subtyping of alcoholics according to specific characteristics has a long tradition in alcoholism research with a number of different typologies that emerged in the literature. The goal of the present study was to test a multidimensional approach of subtyping with characteristics from different axes. Therefore, male inpatients meeting ICD-10 criteria for alcohol dependence were rated on three axes by assessing their degree of sensation seeking (personality axis), age of alcoholism onset (clinical axis) and level of dopamine activity (neurobiological axis). By using a configuration frequency analysis, we identified a subtype that was characterized by high sensation seeking early age of alcoholism onset and high dopamine activity. This subtype, which is in accordance with clinical experience and cannot be explained by antisocial personality disorder, embodied a significantly greater proportion of alcoholics than expected. The result emphasizes the usefulness of multidimensional approaches integrating personality, clinical and neurobiological characteristics.     

Alcoholism and antisocial personality. The sociobiology of an addiction

Alcohol consumption may become adaptive from the evolutionary viewpoint when drinking settings and intoxication can be used to enhance the "cheating" reproductive strategy of antisocial personality disorder. This may explain the selective pressures leading to the association of familial alcoholism and antisocial personality disorder.     

Clinical importance of age at onset in type 1 and type 2 primary alcoholics

Alcoholics have been proposed to be comprised of subtypes who differ in their age at onset and in type 1 vs type 2 characteristics. This study examined whether the clinical course of primary alcoholics was associated with age at onset as well as the type 1-vs-type 2 classification scheme. Interviews with 171 consecutive primary alcoholic men entering an alcohol treatment program revealed that age at onset of alcoholism was correlated with alcohol, drug, and childhood criminality problem histories. Neither classification of these alcoholics into discrete type 1 and type 2 categories nor placing them along a continuum of type 2 characteristics was consistently associated with severity of clinical histories. These findings underscore the clinical importance of age at onset and suggest the possibility that the type 2 prototype might represent a separate diagnosis, antisocial personality disorder, and not alcoholism itself.     

Association of respondent psychiatric comorbidity with family history of comorbidity: Results from the National Epidemiologic Survey on Alcohol and Related Conditions-III

ObjectiveSubstance use disorders and major psychiatric disorders are common, highly comorbid with each other, and familial. However, the extent to which comorbidity is itself familial remains unclear. The purpose of this study is to investigate associations between comorbidity among respondents with family history of comorbidity.MethodsWe analyzed data from the National Epidemiologic Survey on Alcohol and Related Conditions-III to study the associations of family history (FH) of comorbidity among alcoholism, drug problems, depression, antisocial behavior, and anxiety disorders in parents and maternal and paternal grandparents with corresponding DSM-5 diagnostic comorbidity among respondents. We utilized multivariable multinomial logistic regression models controlling for age, sex, race, education, family income, marital status, and adverse childhood experiences (ACEs).ResultsAll comorbid associations of any two disorders with FH were statistically significant; almost all adjusted odds ratios (ORs) for respondent comorbidity in the presence of FH of the parallel comorbidity exceeded 10. ORs involving antisocial behavior in relatives and antisocial personality disorder in respondents were consistently larger than those for any other pairs of disorders. After further adjustment for ACEs, most patterns of association were similar but the ORs were reduced twofold to threefold. ACEs may be mediators in relationships between familial and respondent comorbidities.ConclusionFurther investigations of relationships among familial comorbidity, ACEs, and respondents' diagnoses may improve understanding of comorbidity.     

Use of health services by men with and without antisocial personality disorder who are alcohol dependent

In a sample of 104 medically stable male veterans with alcohol dependence, rates of health service utilization were compared for 48 patients with a primary diagnosis of antisocial personality disorder and 56 patients without this diagnosis. Patients were diagnosed using DSM-IV lifetime criteria; previous utilization of health services was based on self-reports. Although a similar proportion of both groups reported previous service use, patients with antisocial personality disorder reported using more substance abuse treatment services than those with a primary diagnosis of alcohol dependence. Between-group multiple regression analysis showed that an earlier age at onset of alcoholism and a history of a comorbid substance-induced mental disorder best predicted higher rates of use of substance abuse treatment.     

Clusters in a cohort of untreated schizophrenia: prognostic importance, atypical cases and the familial versus sporadic distinction.

In search of features of prognostic importance, a cohort of patients admitted to a mental hospital in 1925 was investigated by means of multivariate clustering techniques. Using K-means cluster analysis or Q-factor analysis, a group containing cases with unfavourable prognosis was isolated. Other groups derived were prognostically heterogeneous. One group of patients, in early phases similar to good prognosis schizoaffective psychoses, could be distinguished and characterized by non-symptom items. There was initial periodicity and onset was acute. They were, on average, younger than the other subjects and there was no personality deviation or emotional disturbance before onset of disease. A family history of mental illness was rare. Two of the factors were positively and negatively characterized by items covering familial history of mental illness, thus seemingly confirming the familial vs sporadic distinction in the subclassification of schizophrenia. Though the clinical pictures were distinctively different at the time when the ratings underlying the analysis were made, approximately the same proportion of cases in the two groups had independently been diagnosed as paranoid schizophrenia--also taking the course of illness into account. It could furthermore be shown that the population at risk--siblings and children of subjects--as well as the observed number of years at risk in these groups were significantly smaller in the sporadic group than in the familial group. This was a combined effect of a lower fertility in subjects and parents in the sporadic group and a higher rate of drop out due to mortality and other reasons among siblings of these subjects. The same tendency was indicated when subjects with and without family history irrespective of factor belongingness were compared. It cannot be concluded that the familial vs sporadic distinction is without relevance in the research on schizophrenia, but its essence may easily be obscured, if the population at risk is not taken into account.     

Clinical and temperamental differences between early- and late-onset alcoholism in Korean men

OBJECTIVES: The aims of this study were to elucidate the clinical and temperamental differences between early- and late-onset alcoholism among Korean men and to ascertain the validity of Cloninger's typology model of alcoholism for Koreans. METHODS: All of the subjects were screened after a detoxification period of at least 2 weeks using the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I Disorders for diagnosing alcohol dependence and identifying psychiatric comorbidities. The Korean version of the tridimensional personality questionnaire was then administered to 173 male alcoholic inpatients; and information regarding their criminality, family history of alcoholism, and age at the onset of alcohol-related problems was gathered. We divided the patients into 2 groups based on the age at the onset of alcoholism: (1) early onset (n = 80), when they were up to 25 years old at the onset, and (2) late onset (n = 93), when they were older than 25 years at the onset. RESULTS: Early-onset patients exhibited more criminality (chi2 = 15.45, df = 1, P < .001, odds ratio [OR] = 3.84, 95% confidence interval [CI] = 1.93-7.65), suicide attempts (chi2 = 7.92, df = 1, P = .005, OR [95% CI] = 3.14 [1.38-7.15]), and family history of alcoholism (chi2 = 24.75, df = 1, P < .001, OR [95% CI] = 5.27 [2.67-10.37]). With regard to the tridimensional personality questionnaire profile, the early-onset patients exhibited a higher score of novelty seeking (t = 3.42, P = .001), with the difference still being significant after adjusting for age by analysis of covariance (using age as a covariate) (F = 5.928, P = .016). However, harm avoidance (t = -0.13, P = .89), reward dependence (t = -0.19, P = .85), and persistence (t = -0.62, P = .54) did not differ between the 2 groups. CONCLUSIONS: There were several distinct clinical and temperamental differences between early- and late-onset alcoholism among Korean male alcoholic patients. It is suggested that the age at the onset of alcoholism can be used to discriminate alcoholic subtypes. Our data also partly support Cloninger's typology of 2 types of alcoholic individuals.     

Mental disorders among alcoholics. Relationship to age of onset and cerebrospinal fluid neuropeptides.

Eighty-one percent of 339 alcoholics participating in a research program were found to have associated mental disorders. Alcoholics with onset of heavy drinking before 20 years of age had significantly more antisocial personality traits, drug abuse, bipolar disorder, panic disorder, suicide attempts, and paternal alcoholism than alcoholics with onset after age 20 years. Alcoholics with onset before and after 20 years of age also differed significantly from each other for cerebrospinal fluid concentrations of diazepam-binding inhibitor and somatostatin. These results support the notion that age of onset may delineate subgroups of alcoholics with significant clinical and neurochemical differences.
