Early development of an infant with 18q- syndrome
Insights
This study details the early development of an infant with 18q- syndrome, a rare chromosomal disorder. The child showed moderate delays, responding well to early intervention, similar to Down
Area of Science:
- Genetics
- Developmental Psychology
- Pediatrics
Background:
- 18q- syndrome is a rare chromosomal disorder involving a deletion on chromosome 18.
- Previous literature suggests varying degrees of intellectual disability in affected individuals.
- Early intellectual and psychological development in infants with 18q- syndrome requires further detailed study.
Observation:
- A case study describes the developmental trajectory of an infant diagnosed with 18q- syndrome over the first 24 months.
- The infant received intensive home advisory services aimed at maximizing developmental potential.
- The child exhibited moderate developmental delays, contrary to some previous reports.
Findings:
- The infant's intellectual and psychological development was monitored closely during the initial two years of life.
- The child demonstrated a positive response to early intervention strategies.
- Prognosis for psychological development appears comparable to Down's syndrome (trisomy 21).
Implications:
- Intensive early intervention services can significantly benefit infants with 18q- syndrome.
- The psychological outlook for 18q- syndrome may be more favorable than previously assumed.
- Parental adjustment to the unique physical characteristics of infants with 18q- syndrome warrants attention.
Abstract:
The early intellectual and psychological development of an infant with 18q- syndrome is described. In this syndrome, which is a rare chromosomal disorder, there is a deletion of a portion of the long arm of chromosome 18. The few previously published accounts have indicated a varying degree of intellectual retardation. This child proved to be moderately delayed only and her development over the first 24 months of age is described in some detail. The family was receiving an intensive home advisory service offered to help maximize the development of pre-school handicapped infants in the area, and it is suggested that in general terms this particular disorder is not remarkably different in respect of psychological prognosis from the more common Down's syndrome, involving trisomy 21, and shows an equally favourable response to such a service. The peculiar appearance of such infants may, however, pose particular problems of parental adjustment.
