DR ANNE MACINTYRE
Longstanding members of The MEA will know that Dr Anne Macintyre has worked as one of our volunteer medical team for almost 20 years. Anne wrote one of the first self-help guides to the illness and has taken a particular interest in the problems relating to medical assessments and examinations for DWP benefits.
Besides having ME, Anne has other health problems. Unfortunately, these have progressively deteriorated over the past few years. As a result she has decided to step down from our medical team and will no longer be dealing with medical or benefit enquiries.
