Maiden Castle circular for today’s dog walk. (Yes, there is a Maiden Castle prehistoric settlement in Durham; the Dorset one isn’t the only one). The autumn colours are glorious, but one strong winter gale will see them off. So pop out if you can and enjoy them while they last! #Durham 😊

There are a lot of difficult challenges around FND (understanding brain dynamics, developing new treatments, etc).
But the most *important* problems are much more easily solved - and yet I hear from folks about these same issues in the community over and over.
