Re-MEND (Building Resilience against Mental illness during Endocrine-sensitive life stages) is a large EU-funded research project. In RE-MEND, mental health will is studied in relation to four life stages: early life, puberty, the period around childbirth and ageing. These sensitive life stages can lay the foundations for developing or being resilient to mental illness later in life. Re-MEND will also aim to decrease stigma around mental health issues, and the hope is to pave a way for more personalised and preventive interventions in the future.
