Multiple deficits : Alzheimer's disease is the most common type of dementia. Memory problems, word finding problems, word substitutions errors, getting lost in places that are familiar are often early symptoms. Also forgetting how to use tools that you used to know how to use. Finally, trouble evaluating info and following plans happen later.
