Today Dr. Eric Berg is going to cover six early signs of dementia. Keep in mind that these could also be signs of other things like a lack of sleep, a blood sugar problem, or many other things—not necessarily dementia. Dementia is a mental decline. Certain parts of the brain are actually shrinking—specifically the hippocampus. If you think you’re showing early signs of dementia, it’s best to act now. Don’t wait until it becomes a bigger problem.
