Annals of Human Genetics, 1988
SummaryBy comparison with a more general theory, data on trisomy in live births, amniocenteses, and spontaneous abortions by year of maternal age are shown to fit a logistic augmented by a proportion independent of maternal age. The frequency of trisomy increases monotonically, with no discrepancy at extremely low or high maternal age.

Obstetrics, Gynaecology & Reproductive Medicine, 2011
Delayed childbearing is a growing trend in developed countries. Between 1989 and 2009, the number of live births to UK women over 40 almost trebled. This accelerating demographic shift is of major clinical and public health concern, because advanced maternal age has consistently been associated with adverse pregnancy outcomes. Current evidence suggests

Decreased maternal age with hydranencephaly
American Journal of Medical Genetics, 1997We studied parental ages of institutionalized children with hydranencephaly. Mothers under age 20 years and under age 18 years were, respectively, 5 and 10 times as frequent as in the general population, and 3 and 4 times more frequent than for institutionalized control patients.

Alzheimer's Disease and Maternal Age
Journal of the American Geriatrics Society, 1982Findings from several studies suggest a relationship between Alzheimer's disease and0020Down's syndrome. It has long been known that advanced maternal age is a risk factor for Down's syndrome, and that mothers who give birth to a child with this syndrome have characteristics consistent with accelerated aging.

Maternal Age and Parental Loss
British Journal of Psychiatry, 1968Maternal age at parturition, birth order, and parental loss have all been extensively investigated as possible causal or concomitant factors in a wide variety of mental disorders. Thus, to take an extreme example, the influence of maternal age on one of the two main kinds of mongolism is well known and can hardly have other than a biological ...

Maternal Age and Autistic Children
Journal of Developmental & Behavioral Pediatrics, 1984Maternal age was examined in 52 autistic children. Two matched control groups were also investigated. Both were matched with the autistic group on age, sex, and birth order. In addition, the first control group was matched with the autistic group according to IQ, while the second control group was composed of normally intelligent children and matched ...
