Eagerly awaited data on the most promising drug in treating Alzheimer's disease is set to be unveiled later.
Patients and scientists hope it could become the first medication to slow the pace of brain decline.

Hints at the drug's effectiveness will be outlined, but Solanezumab has been the great hope of dementia research.
It targets deformed proteins called amyloid that build up in the brain during Alzheimer's.
