Christine's post reminded me of something I had read. It appears in Cambridge UK they have decoded the molecular structure of a substance that is a hallmark of Alzheimer's. They have been able to see the make-up of a destructive protein called TAU in microscopic detail.
This surely means a big step forward for PSP? They are talking about drugs which would prevent Alzheimer's in future. Surely that would lead to a drug to stop PSP? Or am I being too hopeful? They have always said a treatment or cure would come via research into Alzheimer's. Fingers crossed they have started on that road. Although goodness knows how long the road is.
