Since putting together websites (e.g., Brain Injury Care, Neuropsychology Resources, A Better NHS, and London Memory Clinic) involves quite a bit of expense and time, we have allowed for users to make a voluntary donation if they wish. Any donations will also help us to maintain and add resources to the websites. Donations will also be used to fund healthcare projects in developing countries and in the UK. You are free to decide the amount you wish to donate.
