- This stage includes increased forgetfulness, slight difficulty concentrating, decreased work performance. People may get lost more often or have difficulty finding the right words. At this stage, a person’s loved ones will begin to notice a cognitive decline. Takes an average of 7 years before full onset of Dementia at this stage.
Stage 4 : Moderate Cognitive Decline
- This stage includes difficulty concentrating, decreased memory of recent events, and difficulties managing finances or traveling alone to new locations. People have trouble completing complex tasks efficiently or accurately and may be in denial about their symptoms. They may also start withdrawing from family or friends, because socialization becomes difficult. At this stage a physician can detect clear cognitive problems during a patient interview and exam. Average time of stage = 2 years.

Incontinence (loss of bladder or bowel control) is a problem in this stage. Ability to carry on a conversation declines. Personality changes, such as delusions (believing something to be true that is not), compulsions (repeating a simple behavior, such as cleaning), or anxiety and agitation may occur. Average time of stage = 2.5 years.
Stage 7 : Final Stage of Dementia
