Could I Be Suffering From the Early Affects of Alzheimers Disease?

A definite no is the answer to your first question.

As for the second, it's difficult to say. Among a population of normal people there are just going to be some people who seem to have a better memory than others. A lot of people do find their memory gets worse at times of stress or with anxiety or depression. There are also a number of different medical conditions including thyroid problems and vitamin deficiencies which can affect the ability to concentrate etc, so if this is a new thing it might be worth getting checked out, particularly if you have any other symptoms. But it may just be the case that this is something you'll have to live with and work around the best you can.
