Polycystic ovary syndrome (PCOS) affects somewhere between 6 and 20% of women of reproductive age. Typical effects include:
· failure to ovulate;
· high levels of male hormones (androgens), which can lead to acne, seborrhea, hair loss on the scalp, increased body or facial hair, and infrequent or absent menstruation;
· metabolic disruption, including obesity and insulin resistance.
In pregnancy, PCOS is also known to increase the chances of birth complications.
Previous studies have suggested a link between maternal PCOS and ADHD.
A team of Arabian (Saudi and United Arab Emirates) researchers conducted a systematic review of the peer-reviewed medical literature and were able to identify four studies with a total of 1,354,182 participants that could be combined into a meta-analysis.
The meta-analysis found that children born to mothers with PCOS were 43% more likely to develop ADHD. The 95% confidence interval stretched from 35% to 51%, indicating a highly reliable finding.
Moreover, there was between-study variation: They all produced essentially identical results. There was also no sign of publication bias.
"However,"the authors noted, "the reported results do not necessarily provide definitive findings of a causal inference due to the randomized study design. All the included studies were observational in design." With this caution, they could only conclude that "the results of this meta-analysis showed that there might be a link between maternal PCOS and the risk of developing ASD and ADHD in the offspring."
