Alzheimer's Disease: Stages, Symptoms, and Dementia Activities

Introduction to Alzheimer's Disease

Alzheimer's disease is a progressive, degenerative disease that affects the brain and leads to impaired thinking and memory processes. It is the most common form of dementia. Dementia is a syndrome characterized by symptoms such as memory loss, impaired judgment, failure to reason, and extreme changes in mood, behavior, and communication ability.

This disease was first recognized by Dr. Alois Alzheimer in 1906. He identified it by describing two hallmarks of the condition. First, there are "plaques" — millions of microscopic deposits found in the brain that prove toxic to the functioning of brain cells at multiple levels. Second, there are "tangles," which obstruct essential brain processes and choke the living cells responsible for normal brain function. As these cells degenerate and die, certain regions of the brain shrink in size and cause further impairments. Alzheimer's disease is a disorder most common in older populations and is known to affect millions of people above the age of 55. It causes more worry and frustration among the elderly than almost any other disease. The condition may also be hereditary, posing a risk to younger generations when it runs in the family (Robinson, 2011).

The symptoms of this form of dementia include memory loss, although not all memory loss is necessarily attributable to Alzheimer's disease. Research shows that approximately 26 million people worldwide currently suffer from this disease, and estimates suggest that by the year 2050, nearly 15 million Americans will be affected.

Stages and Symptoms of Alzheimer's Disease

Symptoms of Alzheimer's typically develop over time and grow progressively more severe, moving from mild memory loss to serious brain impairment. Changes in the chemical and structural state of the brain lead to the slow, gradual destruction of the ability to create, recognize, learn, memorize, and apply cognitive faculties. As important brain cells are progressively destroyed, personality is eroded and body systems begin to fail (Hill, 2010).

Alzheimer's disease is a progressive neurological disorder that causes severe personality changes and cognitive deterioration. It is characterized by memory loss, intellectual slowing, and related symptoms. Although the progression of the disease may differ for each individual, most patients follow a similar series of stages (Robinson, 2011). With every passing stage, symptoms grow more evident and the severity of the disease increases.

Researchers have identified seven stages to describe how this disease gradually takes hold. These stages can also be grouped broadly into early, middle, and late phases based on severity.

At this stage, the person shows no obvious impairment in memory. These cases will likely not be diagnosed even upon examination by a qualified healthcare professional.

At the second stage, the individual begins to show mild signs of memory loss. The person may be unable to recall recent names, places, events, or commonly used words, as well as the location of frequently used objects such as a watch, papers, pens, or keys. This is the beginning phase and may not be easy for loved ones or friends to notice. It can also be difficult for a doctor to diagnose the disease at such an early stage (Hill, 2010).

At the third stage, clearer evidence of the disease emerges and diagnosis becomes more feasible. People in regular contact with the patient may begin to notice the problem. Symptoms at this stage include:

At this stage, the person shows clear signs of cognitive deterioration that can be identified by observing their behavior in daily situations (Saisan, 2011). Symptoms include:

When a person reaches this stage, the effects become very apparent. Memory loss and slowed brain functioning are clearly noticeable, and the person requires increasing assistance and attention (Segal, 2011). Symptoms include:

Activities for People Living with Dementia

This stage signals severe impairment and a significant loss of brain function. The individual's personality is greatly affected, recall declines sharply, and complete care and assistance are required at all times (Segal, 2011). Symptoms include:

This final stage is the most critical, in which the person loses virtually all control over bodily movements and brain function. The patient loses the ability to respond, speak, or recognize what is happening around them. Symptoms include:

To properly care for a person with dementia, the first step is to devise a daily routine and a list of activities that are productive, interesting, meaningful, and engaging — activities that offer a sense of achievement. It is important to keep in mind that activities should address the person's social, physical, mental, and spiritual needs, since every individual has their own interests and complexities (Russell, 2011). As the disease progresses, tasks will need to be adjusted, and skills and abilities will need to be regularly reassessed. It is important for families and communities to work together to create an environment that supports the mental stability of the patient.

The four essential categories of activities that structure a person's day are work, self-care, leisure, and rest. Maintaining a healthy balance among these categories is critical for managing stress, preserving a positive outlook, and retaining a sense of control over one's life. The negative effects of imbalance are well established: a day filled entirely with demanding tasks and no leisure will produce extreme stress, while a lack of purposeful engagement leads to frustration and dissatisfaction. This balance is equally important for individuals with dementia; maintaining it can help stabilize the patient's condition or slow deterioration (Schneider, 2010).

Conclusion

Once activities are recognized, it is important to devise a plan for each person separately based on individual interests and preferences. Every individual's work history, background, leisure interests, habits, and routines determine the kind of activities they would enjoy in their daily routine. Helpful information can be obtained from family members and close associates to assist caregivers in building appropriate plans. The overarching goal is to modify and present activities in a way that is interesting and accessible for the person living with dementia, ultimately preserving dignity, purpose, and quality of life for as long as possible.
