Higher rates of post-natal depression among autistic mothers

̽��ֱ��team recruited an advisory panel of autistic mothers with whom they co-developed an anonymous, online survey. After matching, this was completed by 355 autistic and 132 non-autistic mothers, each of whom had at least one autistic child.

Sixty percent of autistic mothers in the study reported they had experienced post-natal depression. By comparison, only 12% of women in the general population experience post-natal depression. In addition, autistic mothers had more difficulties in multi-tasking, coping with domestic responsibilities, and creating social opportunities for their child.

̽��ֱ��study also found that when autistic mothers disclosed their autism diagnosis to a professional, they were not believed the majority of the time. Autistic women felt misunderstood by professionals more frequently during pre- and post-natal appointments and found motherhood an isolating experience. Despite these challenges, autistic mothers reported they were able to act in the best interest of their child, putting their child’s needs first and seeking opportunities to boost their child’s self-confidence.

Dr Alexa Pohl, who led the study, said: “Autistic mothers face unique challenges during the perinatal period and parenthood. Despite these challenges, an overwhelming majority of autistic mothers reported that parenting overall was a rewarding experience. This research highlights the need for increased awareness of the experiences of motherhood for autistic women and the need for more tailored support.”

Professor Simon Baron-Cohen, Director of the Autism Research Centre at Cambridge, and part of the team, said: “This worryingly high number of autistic mothers who experience post-natal depression means we are failing them and their infants at a critical point in their lives. We now need more research into why the rates are so much higher, whether they are seeking help and not getting it, or if they are not seeking help and for what reasons. A new research priority is to develop autism-relevant screening tools and interventions for post-natal depression in these mothers.”

Monique Blakemore, an autistic advocate and member of the team, said: “This vital study was initiated by the autistic community, who collaborated as equal partners with researchers in the design, dissemination and interpretation of the survey. This is an excellent example of what can be achieved through such partnership.”

The study was supported by the National Institute of Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care (CLAHRC), East of England, at Cambridgeshire and Peterborough NHS Foundation Trust, the Autism Research Trust, the MRC, the NIHR Cambridge Biomedical Research Centre, and Autistica.

Autistic mothers are more likely to report post-natal depression compared to non-autistic mothers, according to a new study of mothers of autistic children carried out by researchers at the ̽��ֱ�� of Cambridge. A better understanding of the experiences of autistic mothers during pregnancy and the post-natal period is critical to improving wellbeing. ̽��ֱ��results are published in Molecular Autism.

High levels of oestrogen in the womb linked to autism

cjb250 — Mon, 29 Jul 2019 08:25:40 +0000

̽��ֱ��discovery adds further evidence to support the prenatal sex steroid theory of autism first proposed 20 years ago.

In 2015, a team of scientists at the ̽��ֱ�� of Cambridge and the State Serum Institute in Denmark measured the levels of four prenatal steroid hormones, including two known as androgens, in the amniotic fluid in the womb and discovered that they were higher in male foetuses who later developed autism. These androgens are produced in higher quantities in male than in female foetuses on average, so might also explain why autism occurs more often in boys. They are also known to masculinise parts of the brain, and to have effects on the number of connections between brain cells.

Today, the same scientists have built on their previous findings by testing the amniotic fluid samples from the same 98 individuals sampled from the Danish Biobank, which has collected amniotic samples from over 100,000 pregnancies, but this time looking at another set of prenatal sex steroid hormones called oestrogens. This is an important next step because some of the hormones previously studied are directly converted into oestrogens.

All four oestrogens were significantly elevated, on average, in the 98 foetuses who later developed autism, compared to the 177 foetuses who did not. High levels of prenatal oestrogens were even more predictive of likelihood of autism than were high levels of prenatal androgens (such as testosterone). Contrary to popular belief that associates oestrogens with feminisation, prenatal oestrogens have effects on brain growth and also masculinise the brain in many mammals.

Professor Simon Baron-Cohen, Director of the Autism Research Centre at the ̽��ֱ�� of Cambridge, who led this study and who first proposed the prenatal sex steroid theory of autism, said: “This new finding supports the idea that increased prenatal sex steroid hormones are one of the potential causes for the condition. Genetics is well established as another, and these hormones likely interact with genetic factors to affect the developing foetal brain.”

Alex Tsompanidis, a PhD student in Cambridge who worked on the study, said: “These elevated hormones could be coming from the mother, the baby or the placenta. Our next step should be to study all these possible sources and how they interact during pregnancy.”

Dr Alexa Pohl, part of the Cambridge team, said: “This finding is exciting because the role of oestrogens in autism has hardly been studied, and we hope that we can learn more about how they contribute to foetal brain development in further experiments. We still need to see whether the same result holds true in autistic females.”

However, the team cautioned that these findings cannot and should not be used to screen for autism. “We are interested in understanding autism, not preventing it,” added Professor Baron- Cohen.

Dr Arieh Cohen, the biochemist on the team, based at the State Serum Institute in Copenhagen, said: “This is a terrific example of how a unique biobank set up 40 years ago is still reaping scientific fruit today in unimagined ways, through international collaboration.”
