Can you tell me an examples of types of activities you do with a person who you have worked with and experience dementia?

Use your mind/body: At all stages of dementia strengthening brain connections (called synapses) is the goal. We do not have proven therapies in humans with dementia that can do this. However, any type of physical or mental exercize will help you feel better at any stage of dementia.
Aroma therapy, pet therapy, music therapy are but a few modalities I recommend.

How definitive is an MRI as a screening device to rule out dementia, either alzheimer's or other types?

Cognitive and memory changes can be happening long before physical changes show up on an mri. The more definitive findings are on clinical interviews -- with specialized neuropsychological testing may be helpful also. ...Read more
