Psychological characteristics and development of narcotic-addicted infants

Interactive skills of infants with their high-risk mothers

In this pilot study, the interactive skills of infants with their high-risk, substance-dependent mothers were explored in residential treatment from pregnancy until the infant was 6 months of age. Fourteen mother-infant pairs were videotaped in feeding and free play situations at 6 months after birth. A comparison, low-risk group consisted of 12 ordinary Finnish mother-infant pairs with minimal clinical risks. The findings show significantly higher levels of dyadic interactive deficiencies among the high-risk mother-infant pairs compared to the low-risk pairs, displayed especially in the feeding situation as lack of mutuality and flat, empty, constricted affective tone of interaction. Also, more interactive deficiencies were found among the high-risk infants compared to the low-risk infants, but the differences were not significant. In this study, this finding might reflect the reduced amount of somatic complications and the benefits of treatment, the impacts of which were not explored. The differences between the high- and low-risk infants were displayed as more withdrawal, depressed mood and avoiding behavior and as less alertness and attentional abilities, robustness and focus on parent's emotional state among the high-risk group.

Neurologic complications of substance abuse

In addition to overdose, withdrawal, and addictive behavior, licit and illicit drugs produce a wide range of neurologic complications. Trauma results from intoxication and from violence related to a drug's illegality. Infection, including AIDS, is most often a consequence of parenteral use. Seizures can be secondary to either toxicity or withdrawal. Stroke can be ischemic or hemorrhagic. Persistent cognitive dysfunction affects alcoholics and probably users of other drugs as well. Teratogenicity is better documented for ethanol and tobacco than for illicit drugs. Other complications of recreational drug use include peripheral neuropathy, myelopathy, parkinsonism, leukoencephalopathy, optic atrophy, and cerebellar ataxia.

Maternal substance abuse: infant psychiatric interest: a review and a hypothetical model of interaction

Substance abuse problems have strongly increased among Finnish women during the last decade. The negative effects that maternal substance abuse is thought to have on the quality of early mother-baby interaction are an area of interest and concern to specialists in infant mental health. During pregnancy and the newborn period of the infant, substance-abusing women have been shown to be especially willing and able to reduce use once the problem is identified. The desire to stop abusing substances appears to be predicated on a strong desire to be a good mother to the child. Interventions that focus on abstaining during pregnancy and on the early mother-child relationship have shown promise in helping these mothers improve the developmental prognosis of the child and become better parents through sobriety.

Behaviour in first year after drug dependent pregnancy

Neurobehavioural development of a group of 35 infants of drug dependent mothers and of a reference group of 37 infants was compared. Two tailed testing showed that at the age of 3 months the infants of drug dependent mothers seemed to be more active than the reference group; at 6 months, however, no difference was found. On the infant behaviour temperament questionnaire, infants of drug dependent mothers tended to have slightly better scores for 'duration of orienting' at the age of 9 months; five other dimensions of behaviour did not differ between the groups. The Bayley scales of infant development and neurological examination according to the method of Touwen did not show any significant differences among the groups at the ages of 6 or 12 months. At 12 months infants of drug dependent mothers had slightly but not significantly worse results on electroencephalography. Studied with multidisciplinary measurements, the development of infants of drug dependent mothers does not seem to diverge particularly from the development of the reference group.

Differences between dropouts and active participants in a pediatric clinic for substance abuse mothers

We compared the maternal and birth characteristics of 87 first-year dropouts with 103 active participants of a pediatric clinic which provides long-term follow-up care to offspring exposed in utero to substance abuse mothers. The age, ethnicity, and marital status of the mother; the type of drug used during pregnancy; and the length, gender, number, and type of addiction problems of the newborn were not significantly different between the two groups. However, the dropouts differed significantly from the active participants in many other aspects. More dropout mothers received no prenatal care and did not have children at home at the time of the present birth. More of them were smokers; had gonorrhea, heart, and kidney problems; and had infections complicating their pregnancy. The dropout newborns were found to have lower birthweight and shorter gestation. These clinical parameters defined a suboptimal group of mothers and children requiring more attention and care. The findings also alert investigators of long-term follow-up studies to be aware of basic differences between nonparticipants and participants.
