Insights
Fetal alcohol spectrum disorders (FASD) and neurodevelopmental deficits were common in Brazilian orphanage children, with 17% diagnosed with FASD. Prenatal alcohol exposure significantly impacts these vulnerable children, highlighting the need for further research and prevention.
Area of Science:
- Pediatrics
- Neuroscience
- Ophthalmology
Background:
- Investigated the prevalence of fetal alcohol spectrum disorders (FASD) and ophthalmologic anomalies in Brazilian orphanage children.
- Identified negligence, abuse, and abandonment as primary reasons for institutionalization in 61% of cases.
Purpose of the Study:
- To determine the frequency of FASD and ophthalmologic abnormalities in children residing in a Brazilian orphanage.
- To assess the impact of prenatal alcohol exposure and associated neurodevelopmental deficits.
Main Methods:
- Prospective study involving 94 children in a Brazilian orphanage.
- Comprehensive examinations by a multidisciplinary team including pediatricians, neurologists, psychologists, neuropsychiatrists, and ophthalmologists.
Main Results:
- 50% of children had mothers with a history of alcohol abuse.
- 17% were diagnosed with FASD (Fetal Alcohol Syndrome, partial FAS, alcohol-related neurodevelopmental disorder).
- 16% exhibited ophthalmological findings; 47% had neurodevelopmental/behavioral/cognitive deficits.
Conclusions:
- A significant proportion of orphanage children exhibit neurodevelopmental disorders and signs of prenatal alcohol damage.
- Urgent need for broader studies on FASD burden in Brazil and South America to inform prevention strategies.
Background:
The objective was to investigate the frequency of fetal alcohol spectrum disorders (FASD) and ophthalmologic anomalies in orphanage children in Brazil.
Methods:
A prospective study was performed on 94 children living in an orphanage in Brazil. The children were examined by a multidisciplinary team consisting of specialists in pediatrics, neurology, psychology, neuropsychiatry, and ophthalmology.
Results:
The main reasons for living in the orphanage, in 61% of the children, were negligence, child abuse, and abandonment. Of all the children studied, 50% had mothers with known alcohol abuse and 47% had one or more diagnoses of neurodevelopmental/behavioral and/or cognitive deficits. General developmental delay was found in 18%, intellectual disability in 3%, cognitive impairment in 27%, attention-deficit/hyperactivity disorder in 14%, and autism in 3%. Altogether 17% had FASD, comprising three children with fetal alcohol syndrome (FAS), six with partial FAS, and seven with alcohol-related neurodevelopmental disorder. 16% had ophthalmological findings such as poor vision, strabismus, and dysmorphology of the optic nerves. Twenty-eight children (30%) were adopted from the orphanage; of these, six had FASD (two FAS, three partial FAS, one alcohol-related neurodevelopmental disorder), five had attention-deficit/hyperactivity disorder, and eight had developmental delay.
Conclusion:
Nearly half of the children living in the orphanage had neurodevelopmental disorders and a considerable number showed signs of damage from prenatal alcohol exposure. A broader look at the problem of FASD in Brazil and other South American countries is desirable to document the burden of disease and provide data for targeting prevention efforts.
