Health Minister Claire Christian says she doesn't know how much the Island is paying for people taking dementia drugs.
During this week's House of Keys sitting she faced questions from Arbory Castletown and Malew MHK Jason Moorhouse about the number of dementia sufferers on the Island.
She said 551 people who'd been diagnosed with the condition were registered with GPs, with 431 on medication.
But she couldn't reveal the total cost of paying for the medicines:
