But don't forget to be lost: everything you need to know about Alzheimer's.

In light of World Alzheimer’s Day, this article aims to provide comprehensive information about this form of dementia. What are the early signs of Alzheimer’s disease, and how can family members best cope with the diagnosis? World Alzheimer’s Day is intended to raise awareness and bring this issue to the public’s attention. Alzheimer’s dementia is one of the most common forms of dementia and is expected to increase significantly in the coming years due to demographic changes. In 2023, approximately 1.8 million people with dementia were living in Germany. According to current estimates, this number is expected to increase by nearly one million by 2025. This makes it all the more important to understand the most common causes of dementia as well as the early signs of the disease. In this article, you will learn everything about the disease and what you, as a family member, can do to improve the patient’s quality of life.

What is Alzheimer’s disease?

Alzheimer’s disease is the most common form of dementia. Alzheimer’s disease develops when nerve cells in the brain gradually die off. It is currently known that in Alzheimer’s patients, protein deposits called plaques accumulate in the hippocampus. This causes nerve cells to die, leading to increasing cognitive impairment. In addition, another protein called tau protein is believed to be present in the brain, which is altered in such a way that it can no longer support the nutrient supply and stability of brain cells. Dementia leads to progressively worsening memory, language disorders, problems with planning, and difficulties with concentration and attention. Alzheimer’s dementia is incurable. However, there are both pharmacological and non-pharmacological methods to positively influence the course of dementia. Special antibody medications are designed to remove the aforementioned plaques and thus delay the progression of the disease. Based on the current state of research, it is not yet possible to completely halt the process. Risk factors—that is, conditions that, when present, increase the likelihood of developing the disease—include diabetes, depression, high blood pressure, smoking and heavy alcohol consumption, obesity, limited social contact, hearing loss, and low educational attainment. None of these factors are primary triggers of Alzheimer’s disease; they merely increase the risk of developing it. There are also several protective factors—that is, factors that minimize the likelihood of developing Alzheimer’s. These include a good education, regular physical and mental activity, a supportive social environment, a balanced diet, and moderate alcohol consumption. An Alzheimer’s diagnosis and the accompanying symptoms can be frightening and lead to great uncertainty, which is why it is all the more important to have a stable support network around you and to treat the person affected with love and patience.

Symptoms of Alzheimer's Dementia

Dementia is primarily associated with increased forgetfulness. However, there is far more to the disease than just forgetfulness. The progression of the disease can vary somewhat from person to person, but at its core, it follows the same pattern.

• Memory: As the disease progresses, memory function declines. Initially, short-term memory is affected, and later, long-term memory as well. Problems with short-term memory manifest in the fact that those affected can no longer recall recently discussed topics, such as shopping lists or information from a text they have just read. Deficits in long-term memory manifest as an inability to recall events from one’s own life, such as weddings or major birthday celebrations
• .
• Language: Initially, Alzheimer’s dementia may become apparent in speech, as the person can no longer recall individual words or finish their sentences. This is often accompanied by a loss of train of thought, making longer conversations impossible.
• Personality changes: As the disease progresses, profound changes in personality may occur. These changes can be in stark contrast to the person’s personality when healthy. Individuals may become increasingly aggressive, for example when they are frustrated or afraid. Others become very withdrawn and barely speak. They isolate themselves and lose all interest in activities they once enjoyed. In addition, pronounced anxiety and a certain degree of distrust may develop. Affected individuals feel threatened and exhibit paranoid traits.

The four stages of Alzheimer’s dementia

1. Mild cognitive impairment

In this phase, there are mild cognitive impairments that are usually not noticed by those affected but can be observed by outsiders. However, they can be detected through a diagnostic test. Individuals at this stage do not yet require assistance; they can still manage their daily lives on their own. In summary, this first phase is characterized by the presence of mild cognitive impairments that only minimally affect the individual’s daily life.

 2. Early stage of Alzheimer’s dementia

In this stage, the first deficits in short-term memory appear. Information that was recently communicated to them, whether in conversations or over the phone, can no longer be recalled. Those affected at this stage have trouble following conversations. They also have difficulty finding the right words and often lose their train of thought during conversations. The first problems with spatial and temporal orientation begin to emerge. For example, they may miss appointments or be unable to find their parked car. They can still manage most aspects of daily life, and household tasks can generally be handled. However, they need assistance with more complex tasks. At this stage, those affected slowly realize that something is wrong and try to hide their deficits as best they can. Humor is often used to distract from memory deficits or orientation problems. Some people also tend to withdraw, meaning they hide from the outside world to conceal their limitations. They avoid new and unfamiliar situations that they may not be able to handle without help. As a result, people at this stage become increasingly insecure and withdraw from the outside world. Along with this, the person’s personality begins to change. Someone who was once very open and Someone who used to be eager for new experiences may now seem very reserved and anxious. They may also become more irritable when things don’t go the way they’d like or when they realize all the things they can no longer do on their own. Depression may also set in. Their mood is low, and activities or hobbies that used to bring them joy no longer hold any appeal, and they find it almost impossible to muster the motivation to do anything. Personal hygiene and household chores are neglected. Social interactions become increasingly rare, and individuals isolate themselves in their homes.

3. Middle Stage of Alzheimer’s Dementia

In this phase, the disease is now clearly noticeable. Deficits are now evident not only in short-term memory but also in long-term memory. This affects memories of declarative long-term memory, more specifically episodic memory. This is responsible for storing important life events such as marriage, children, and other significant life events. People in the middle stage have trouble remembering these important life events. They find it difficult to recall how many children they have, as well as their names and ages. Early childhood memories may surface randomly, and those affected may believe they are currently living through the remembered period. For example, a person may be convinced that they are a child and urgently need to go home to their mother. Spatial orientation deteriorates progressively. People may have trouble finding their house number or, in the worst cases, no longer recognize their own home. Items are repeatedly misplaced and appointments forgotten. People become harder to recognize, and those affected grow increasingly uncertain in their actions, as it is now clearly evident that they have deficits and they also notice this in themselves. Personality changes much more significantly as the disease progresses. The nature of these personality changes varies from person to person. Some become more aggressive, while others become very shy and barely communicate anymore. This can be extremely stressful for family members, as their relative changes more and more, and the new personality can be exhausting and unfamiliar. In addition to personality changes, people in the middle stage experience severe restlessness and nervousness. This manifests as an increased urge to move. This means that those affected pace restlessly without a clear destination. This behavior can also lead to people attempting to escape from their home or care facility. Due to the increasingly diminished sense of time, the sleep-wake cycle can be disrupted, resulting in people wandering around at night and not realizing they need to go to sleep, and then going to bed during the day instead. In summary, people in the middle stage of Alzheimer’s dementia are increasingly dependent on help, as they can no longer manage their daily lives on their own.

4. Late Stage of Alzheimer’s

In the final stage of Alzheimer’s disease, the health of those affected deteriorates progressively. They are now highly susceptible to contracting other illnesses. Lack of exercise and poor nutrition, combined with advanced age, can contribute to a weakening of the general immune system. This makes them extremely vulnerable to infections. This phase is characterized by difficulties with eating, swallowing, and drinking, Severe physical weakness, excessive sleep, and limited verbal communication. Incontinence may also occur, as people with advanced dementia are no longer able to correctly interpret their body’s signals. Managing incontinence requires patience and good care. Products such as incontinence padsand incontinence underwear can help maintain the affected person’s well-being. In summary, people in the final stages require round-the-clock care and are highly susceptible to infections, which in most cases are also the cause of death.

Early detection, early action

Now that the individual stages of Alzheimer’s dementia are known, it is important to explain how to recognize dementia early and what you, as a family member, can do to positively influence its progression and take appropriate measures to benefit both your own health and that of the person affected. In the early stages, it is sometimes difficult to recognize the signs. The symptoms of dementia can be identical to those of depression. To be sure which condition is present, you should look for the following signs and contact a doctor to schedule a diagnostic appointment.

• Memory loss: Early signs of memory loss include people no longer remembering things they discussed, frequently asking the same questions, and increasingly misplacing objects.

• Problems with daily activities: An early sign of dementia can also be that familiar tasks become more difficult to perform or lead to confusion.

• Difficulty planning: The person affected has increasing difficulty planning their daily routine.

• Confusion: In the early stages, the person may lose their bearings and no longer know what day it is or where they are.

• Word-finding difficulties: Another sign may be that people have trouble speaking, as they can no longer think of certain words and lose their train of thought during a conversation.

• Social isolation: Due to a fear of no longer being able to manage on their own, people often withdraw to hide their deficits. It is common for them to no longer find any enjoyment in activities they used to like.

• Personality changes: Mood swings can occur even in the early stages. Those affected become more anxious, irritable, and exhibit depressive moods.

What specific steps can I take as a caregiver?

As a caregiver for someone with Alzheimer’s, there are many ways to maintain their well-being and quality of life. People with Alzheimer’s often feel a strong sense of insecurity and are in a depressed mood. The progression of Alzheimer’s disease cannot be stopped. However, steps can be taken to make life as comfortable as possible for those affected. Here are some important things you should keep in mind when interacting with them:

• Patience: Above all, it is essential to be patient and understanding. Since people with Alzheimer’s can be very anxious or suspicious, it is important to take your time and be patient with them.

• Routine and security: It is important to establish a Establishing a routine daily schedule helps prevent stress and provides a sense of security. A structured daily plan is helpful in this regard. It can also be helpful to post a schedule so that the person can always see what’s next on the agenda. An accessible environment should also be created to minimize the risk of injury.

• Communication: The right approach to communication is key here. Be patient if the person has difficulty expressing themselves in conversations or occasionally repeats themselves. It is important that you convey the feeling that the person is being heard. Also pay attention to nonverbal cues and reinforce what is said with a smile or a nod to convey reassurance and appreciation. Avoid using complicated words or long sentences, as this can quickly lead to confusion. Also, avoid complex questions and give the person time to answer.

• Nutrition and Health: Ensure that meals are eaten regularly and that they are healthy and balanced. People with Alzheimer’s often forget to drink, which can quickly lead to dehydration. Engaging in regular physical activity and maintaining social connections are also beneficial for health.  

• Seek professional support: The further the disease progresses, the more help those affected need. As a family member with a job and a family of your own, caring for someone with dementia is unreasonable, which is why it’s important to seek help early on, either in the form of home care services or a care facility. Do your research and choose the best option for you and your loved one. It is important that you do not neglect your own health. Alzheimer’s disease is not only a physical and emotional burden for the person affected; the situation is also stressful for family members. There are various resources available for family members, such as support groups.

Conclusion

An Alzheimer’s diagnosis presents new challenges for everyone involved. With knowledge and understanding of the disease, you can significantly improve the quality of life for the person affected. Science has not yet found a cure for dementia, but numerous studies on this complex disease are currently underway. It is important to stay informed, show understanding and empathy, and build a support network. Early detection is of central importance because it allows for a diagnosis and treatment that can slow the progression of the disease and significantly improve quality of life. For family members, such a diagnosis can also be an extreme burden. It is important to utilize support networks and to take care of one’s own health. It remains a medical and societal task to impart knowledge, build understanding, and find new ways to improve the lives and quality of life of Alzheimer’s patients.
