About the study

about the study

CAH Research at Cambridge is run by the University of Cambridge in conjunction with Cambridge University Hospitals NHS Foundation Trust. The team encompasses leading researchers in the field – you can find out more about us here.

We are looking for individuals aged between 18 and 45 years with a diagnosis of classic congenital adrenal hyperplasia (CAH). We would like to find out how hormone exposure within the womb relates to brain structure and behaviour. It is possible that hormone levels during fetal development influence the structural development of the human brain which in turn influences human behaviour, and this is what we wish to study.

If you decide to participate in our study, you will carry out tasks assessing a range of different behavioural traits, including spatial aptitude, throwing ability, personality characteristics and fine motor ability. We also will use a Magnetic Resonance Imaging (MRI) scanner to obtain images of the structure of your brain and, if you are willing, obtain saliva and blood samples so that we can study your DNA.

You will be asked to travel to Cambridge on a day of your choosing for a one-off session lasting approximately 3.5 hours, 30 minutes of which is spent undergoing the MRI scan. You will receive a contribution of £30 for your time and we will reimburse you for your travel expenses. If you are coming from further afield, we will reimburse you for accommodation and meals while in Cambridge, and can help you make these arrangements if necessary. You will also be given a picture of your brain.
