The Chronic Disease Research Foundation (CDRF), founded in May 1996, is an independent medical research charity. The CDRF funds a wide range of gene research programs that aim to discover the cause of chronic diseases such as long term COVID, cardiovascular disease, obesity, arthritis, dementia, back pain, and migraine. The CDRF runs many successful projects at the Department of Twin Research at St Thomas' Hospital. We hope that the results of this research will contribute to the development of future diagnostic tests and treatments. We rely entirely on non-governmental donations and grants to conduct our research.
