2 Stage:
Mild Cognitive Decline
In this stage of dementia a person has increased forgetfulness, slight difficulty concentrating and 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.
3 Stage.
Moderate Cognitive Decline.
This stage of Dementia 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.

4 Stage.
Moderately Severe Cognitive Decline
People in this stage of dementia have major memory deficiencies and need some assistance to complete their daily activities (dressing, bathing, preparing meals).
Memory loss is more prominent and may include major relevant aspects of current lives; for example, people may not remember their address or phone number and may not know the time or day or where they are.
5 Stage.
Severe Cognitive Decline (Middle Dementia)

Ability to speak 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.
6 Stage.
Very Severe Cognitive Decline (Late Dementia)
This is the last stage of dementia and People in this stage of dementia have essentially no ability to speak or communicate. They require assistance with most activities (e.g., using the toilet, eating).
