The report Wednesday from the Alzheimer Society of Canada that early detection of the disease is crucial to managing the disease rings true for one Surrey, B.C., resident.
Jim Mann writes notes to remember everyday things, but also has kept a journal since he was diagnosed nearly five years ago.
He's sharing parts of the journal now to encourage others with symptoms to see a doctor.
"For me, being proactive was an awful lot better option than just ignoring it, because it certainly won't go away," said Mann, 63.
There is no cure for Alzheimer’s disease, the most common form of dementia but there are new drug therapies that help some patients.
"Early diagnosis allows you to sort of take control of your life," said Mann.
