Children of alcoholics. Predictors for psychopathology and addiction.

Children of alcoholics have a higher risk of psychopathology and alcoholism. Therefore, in 1993 the Amsterdam Institute for Addiction Research initiated a study on vulnerability markers and risk factors in children of alcoholics, aimed at identifying predictors for the development of psychopathology and addiction in children of alcoholics. This article provides a summary of the background, rationales and aims of the study. With more specific and sensitive biological vulnerability markers that indicate risk status, more effective preventive interventions might become available. The biochemical part of the study aims at answering the question whether adenylate cyclase is a vulnerability marker for alcoholism. The psychophysiological part is directed at event-related potentials during task performance to clarify the nature of the brain and cognitive functions that may underlie or relate to vulnerability to alcoholism. The third part, the psychological component, aims at possible psychological mechanisms of enhanced risk of addition in children of alcoholics as well as the relationship with childhood psychopathology.

Psychological mechanisms of enhanced risk of addiction in children of alcoholics: a dual pathway?

The background and rationale of a recently started project of the Amsterdam Institute for Addiction Research are outlined. This project is aimed at the psychological mechanisms underlying an enhanced risk of (later) addiction in children of alcoholics and the relationship with childhood psychopathology. A dual pathway mechanism is proposed, in which the type of alcoholism of the parent plays a major role. The child of a multigenerational primary alcoholic parent may suffer from an inherited mild dysfunction of the prefrontal cortex, expressed in neuropsychological and personality characteristics similar to those of the alcoholic parent. These are impulsive, aggressive and reward-seeking behaviour, response perseveration and, in some children, related psychopathology such as conduct disorders. For a child of a secondary alcoholic parent, another mechanism is proposed. In these children, stress and social learning may lead to negative affectivity and repressive coping style, with emotional problems at a later age, and the risk of falling into the "circle of secondary alcoholism". In both pathways, alcohol-related expectancies are suggested to constitute a "final common pathway" between different risk factors and later alcohol abuse. Specific expectancies might be related to different pathways and to gender differences in later drinking patterns.

Development after prenatal exposure to cocaine, heroin and methadone.

In Amsterdam a longitudinal, prospective and multidisciplinary study on the development of infants of drug-dependent mothers (IDDM) was started in 1983: 35 IDDM and 35 reference infants were originally enrolled. The drug-dependent women had used combinations of methadone, heroin, cocaine and other drugs during pregnancy. Of the IDDM, 80% had to be treated pharmaceutically for neonatal abstinence symptoms (NAS). Physical, neurological, cognitive and the socio-emotional development of the children were studied regularly from birth until 5.5 years of age. Differences between the reference group and the IDDM were found most clearly in cognitive development. The IDDM also had more behavioural problems at some of the ages studied. No group differences were seen in motor development. So far the results of the study show that IDDM and their caregivers need extra support in order to improve early communication and the children's cognitive development.

[Children with autism and related contact disorders: medical aspects].

In children with infantile autism or atypical pervasive developmental disorders somatic aspects play an important role. A review is presented of important hereditary, pre-, peri- and neonatal factors, findings at neurological examination, specific medical disorders and neurochemical and neurophysiological findings. Results of the medical examination of 15 children with autistic or atypical developmental disorders are presented. It is concluded that extensive medical examination of these children is indicated: in 8 out of 15 children a clinically relevant chromosomal, neurological or biochemical disorder could be detected.
