quote: It didn't say if you use your GPS you'll get Alzheimers. It said that the decrease use of the hippocampus, in which using a GPS is ONE example, would set one up to get Alzheimers. There is no absolute link. Just that you should be able to navigate without GPS some time.
quote: McGill researchers found that excessive use of a GPS unit may lead to atrophy of the hippocampus as we age, which puts the person at risk for cognitive problems such as Alzheimer's disease later in life. Alzheimer's disease affects the hippocampus first before any other part of the brain, which leads to problems with spatial orientation and memory.
quote: Either way, using spatial strategies instead of the GPS would be helpful in lessening the deterioration of memory.
