No matter how we laugh them off, those "senior moments," when we briefly forget someone's name or can't find our keys or eyeglasses can trigger a fear of something far more serious. While momentary memory lapses are often a normal part of aging, Alzheimer's disease and other dementias are not.

If you are concerned about the onset of Alzheimer's or know someone diagnosed with the disease, you can attend a free workshop that will explain the causes, risks and warning signs. There also will be a discussion of treatments and stages of the disease.

The seminar, presented by Dawn Hagen from the Long Island chapter of the Alzheimer's Association (alz.org/longisland), is Monday at 2 p.m. at Long Beach Public Library. For information, call 516-432-7200.
