I Can’t Remember.
Older individuals’ complaints about memory lapses (such as trouble remembering recent events) may indicate they are experiencing cognitive problems that are greater than typical age-related changes. The incidence of Alzheimer’s disease and other dementias is expected to rise in the United States as adults 65 and older are projected to double in number over the next two decades.  Clinicians are now incorporating cognitive screening tests as part of annual wellness visits for older people.
