This section explains specific rare conditions and the biological mechanisms behind them, including genetic changes, immune dysfunction, metabolic disorders, neurological processes, and other underlying causes of disease.
Articles look at how conditions develop, how they affect different organs and systems, and why symptoms can vary so much between individuals. Alongside condition overviews, this section also explores the science of how diseases work, helping readers understand the mechanisms that researchers target when developing new treatments. We also spotlight individual conditions, highlight patient organisations and charities, and signpost reliable sources of support, information, and specialist care, so readers know where to go for further help.
The aim is to provide accurate, evidence-based explanations that make complex biology clearer without oversimplifying the science.
