EXPLORING THE PROGRESSION OF ALZHEIMER’S DISEASE.
This Help Sheet discusses the progression of Alzheimer’s disease from the early stages to the final stages of advanced dementia.
People with Alzheimer’s disease differ in the patterns of problems they have, and the speed with which their abilities deteriorate. Their abilities may change from day to day, or even within the same day. What is certain though, is that the person’s abilities will deteriorate over time.
STAGES OF ALZHEIMER’S DISEASE
Some of the features of Alzheimer’s disease are commonly classified into three stages or phases. It is important to remember that not all of these features will be present in every person, and that they might occur at different stages for some people. However, it remains a useful description of the general progression of dementia caused by Alzheimer’s disease.
MILD ALZHEIMER’S DISEASE
Sometimes this stage is only apparent in hindsight. The onset of Alzheimer’s is usually very gradual, and it is often impossible to identify the exact time it began.
The person might:
Appear more apathetic, with less sparkle
Lose interest in hobbies and activities
Be less willing to try new things
Be less able to adapt to change
Be slower to grasp complex ideas and take longer with routine jobs
Become more forgetful of recent events
Become confused or disoriented to time and place
Become lost if away from familiar surroundings
Be more likely to repeat themselves or lose the thread of their conversation
Be more irritable or upset if they fail at something
Have difficulty managing finances
Have difficulty shopping or preparing meals
MODERATE ALZHEIMER’S DISEASE
At this stage the person’s problems are more apparent and disabling. A person with moderate Alzheimer’s is not able to live independently, but requires significant day-to-day support.
The person might:
Be very forgetful of current and recent events. Memory for the distant past is generally OK, but some details may be forgotten or confused.
Be often confused regarding time and place
Become lost more easily
Forget names of family or friends, or confuse one family member with another
Forget saucepans and kettles on the stove or leave gas lit
Be less able to perform simple calculations
Show poor judgement and make poor decisions
Wander around streets, perhaps at night, sometimes becoming lost
Behave inappropriately, for example going outdoors in nightwear
See or hear things that are not there or become suspicious of others
Become very repetitive
Be neglectful of hygiene or eating
Be unable to choose appropriate clothing for the weather or occasion
Become angry, upset or distressed through frustration
SEVERE ALZHEIMER’S DISEASE
At this third stage, the person is severely disabled and needs continuous care for all daily activities.
The person might:
Be unable to remember current or recent events, for instance forgetting that they have just had a meal or being unable to recall where they live
Be unable to recall important events or facts from their early life
Show confused recognition of friends and family
Fail to recognise everyday objects
Lose their ability to understand or use speech
Need help with eating, washing, bathing, brushing teeth, toileting and dressing
Become incontinent
Be disturbed at night
Be restless or fidgety
Call out frequently or become aggressive
Have difficulty walking and other movement problems including rigidity
Immobility will become permanent, and in the final stages the person will be unable to sit up independently and be bedridden. As a terminal illness, Alzheimer’s disease progresses until the end of life, when extensive care is required.
REMEMBER:
Some abilities remain, although many are lost as the disease progresses. The person may still keep their sense of touch and hearing, and their ability to respond to emotion, even in the final stages. At all stages of Alzheimer’s disease, treatments and support services are available to reduce the impact of the problems experienced. These should be utilized to ensure the best possible quality of life for every person affected by Alzheimer’s disease.
