Hi Im new to this, and my 76 yr old mum is being tested for CJD. She first became unwell in Dec 11 when she was found with a blood clot in her heart but since then she has been on what I call fast track dementia In three months she has gone from a fit healthy, full of life independent mum to a small, frail, old lady that cant do any thing for herself except get a glass or spoon to her mouth.
