Alzheimer’s disease is a progressive brain condition. It is characterized by alterations in the brain that result in the deposition of certain proteins. The brain shrinks and finally dies as a result of Alzheimer’s disease. Dementia, which is characterized by a slow loss of memory, reasoning, conduct, and social skills, is most frequently caused by Alzheimer’s disease. A person’s capacity to function is impacted by these changes.
The disorder was named after Dr. Alois Alzheimer, who first described the condition in 1906. Alzheimer’s disease affects around 6.5 million Americans aged 65 and older. More than 70% of them are older than 75 years old. About 60% to 70% of the 55 million persons with dementia globally are thought to have Alzheimer’s disease.
The disease’s early symptoms include forgetting recent conversations or experiences. It eventually leads to severe memory issues and a loss of the capacity to carry out daily chores. The symptoms’ progression may be slowed or improved by medications. Programs and services can benefit both those who are ill and the people who care for them.
Alzheimer’s disease cannot be treated; there is no cure. Dehydration, starvation, or infection might result from significant brain function loss in its advanced stages. These complications can result in death.
Stages of Alzheimer’s Disease
Alzheimer’s disease can range from mild to severe. The severity of cognitive decline is measured on a scale that starts off mild and progresses through moderate impairment and then severe impairment.
The phases of Alzheimer’s and some of the symptoms that distinguish them are covered in the sections that follow.
Mild Alzheimer’s Disease
Memory issues and cognitive challenges, which may include the following, appear in people with mild Alzheimer’s disease.
- Task completion takes longer than usual
- Financial or bill-paying difficulties
- Stumbling and getting lost, changing demeanor and actions, such as pacing, hiding items, or being more easily agitated
Moderate Alzheimer’s Disease
Language, senses, logic, and consciousness-related areas of the brain are harmed in moderate Alzheimer’s disease. Symptoms that may result from this include:
- Heightened confusion and memory loss
- Not being able to recognize acquaintances or family
- An unwillingness to acquire new knowledge
- Getting dressed and other multi-stage tasks are tough for them to execute. Adapting to new conditions is also difficult.
- Uncontrollable actions hallucinations, delusions, or paranoia
Severe Alzheimer’s Disease
Plaques and tangles spread throughout the brain in advanced Alzheimer’s disease, significantly shrinking the brain tissue. This may result in:
- A lack of communication,
- A need for care from others,
- A tendency to spend the majority of time in bed
Symptoms of Alzheimer’s Disease
The primary sign of Alzheimer’s disease is memory loss. Early warning indications include having trouble recalling previous conversations or occurrences. But as the illness worsens, memory declines and additional symptoms appear.
A person with the illness may initially be aware of experiencing memory loss and clear-headedness issues. A friend or family member may become more aware of the problems as the symptoms worsen.
Alzheimer’s disease-related brain alterations cause increasing problems with:
1. Memory
Everyone occasionally experiences memory loss, but Alzheimer’s disease-related memory loss is persistent and worsens over time. Memory loss gradually impairs one’s capacity to carry out daily tasks at home or at work.
Alzheimer’s disease sufferers may:
- Repeat questions and phrases again.
- Get lost in areas they used to be familiar with.
- Over time, they lose the names of their loved ones and commonplace items.
- Don’t think about meetings, events, or conversations.
- Have difficulty expressing ideas, describing things, or participating in conversations.
- Items are frequently misplaced and placed in odd places.
2. Personality and Behavior Changes
Moods and behaviors may be affected by the brain alterations that result from Alzheimer’s disease. Issues could involve any of the following:
- Mood changes.
- Mistrust of other people.
- Anger or hostility.
- Depression.
- A decline in motivation for activities.
- Social exclusion.
- Wandering.
- Loss of restraint.
- Alterations in sleep patterns.
- Delusions, such as idea that something has been taken.
3. Making Decisions and Judgments
Reasonable judgment and decision-making skills deteriorate as a result of Alzheimer’s disease. For instance, a person might dress inappropriately for the weather or make poor decisions in social situations. Someone may find it more difficult to respond to everyday issues. For instance, the person can be unable to make decisions while driving or deal with food burning on the stove.
4. Thinking and Reasoning
Concentration and thinking problems are brought on by Alzheimer’s disease, especially when it comes to abstract ideas like numbers. Managing multiple tasks at once is very challenging. To handle money, keep checkbooks balanced, and make on-time payments on bills may be difficult. A person with Alzheimer’s disease may eventually lose the ability to comprehend and use numbers.
5. Planning and Carrying out Routine Duties
Simple tasks that need following steps in order become challenging. This could involve organizing and preparing a meal or engaging in a favorite activity. People with severe cases of Alzheimer’s eventually lose the ability to perform fundamental chores like dressing and taking a shower.
6. Retained Abilities
People with Alzheimer’s disease are able to retain some skills even as their symptoms worsen, despite significant changes to their memory and cognitive abilities. Reading or listening to books, telling stories, sharing memories, singing, listening to music, dancing, painting, or making crafts are just a few examples of talents that might be preserved. Because the brain regions that govern these skills are impaired later in the disease’s progression, they may be preserved for a longer period of time.
Prevention Tips
Adaptable elements that could aid in preventing Alzheimer’s disease include:
- Exercise on a regular basis
- Keeping a healthy cardiovascular system by eating a diverse and nutritious diet
- Control of the risks of high blood pressure, diabetes, obesity, and cardiovascular disease
- Maintaining mental activity throughout life
Risk Factors
Alzheimer’s disease risk factors that cannot be avoided include:
- Having a family history of Alzheimer’s, and
- Aging
- Possessing specific genes
Added risk elements for Alzheimer’s disease include exposure to some environmental toxins, such as hazardous metals, herbicides, and industrial chemicals. severe or repetitive traumatic brain injuries.
When to Visit the Doctor
Memory loss or other dementia symptoms can be brought on by a number of illnesses. Some of such illnesses are curable. Speak with your healthcare practitioner if you have any concerns about your memory or other cognitive abilities.
Talk about your concerns and offer to visit a provider with a family member or friend if you are worried about the thinking abilities you have noticed in them.
Treatments
Alzheimer’s disease currently has no known treatment. Brain cells cannot be revived after they have died. However, treatments can ease its symptoms and enhance both the patient’s, their family’s and careers’ quality of life.
These are important aspects of dementia care:
- Efficient management of any illnesses that coexist with activities and daycare programs for Alzheimer’s patients
- Participation of support services and groups
- Medications and treatments for behavioral changes

Conclusion
Alzheimer’s disease is a neurological ailment. Memory loss and cognitive impairment result from the accumulation of plaques and tangles in the brain as well as from cell death.
There is currently no cure for the condition, although medications and other therapies can help to lessen the cognitive, emotional, and behavioral symptoms and enhance the quality of life for the patient.
