Alzheimer’s disease is the most devastating neurological disorder that affects millions of people across the world. This is one of the most prevalent forms of dementia, debilitating cognitive functions, memory, and the person’s ability to perform everyday activities. The problem is not only for the person diagnosed; a tremendous emotional and physical burden is also placed on the family and caregivers. This detailed handbook will explore what Alzheimer’s is: its symptoms, causes, risk factors, diagnosis, treatment, management strategies, and how to support clients living with the condition.

What is Alzheimer’s Disease?
Alzheimer’s disease is a neurological progressive disorder that causes the degeneration and death of brain cells. Said to be named after Dr. Alois Alzheimer, the latter first described the condition in 1906, after his research based on changes in brain tissue of a woman who died because of mental illness. It is described by abnormal protein clumping in the brain, which eventually extinguishes the neurons, resulting in the loss of brain function.
The progression of the disease is marked by the decline of the cognitive abilities, memory, and the capability of performing everyday activities. Normally, Alzheimer’s begins with light memory loss and later transforms into a phase at which one is unable to hold any conversation or even respond to their environment. It is a disease that is chronic and progresses worse with time; its symptoms go on to get even more severe.
Symptoms of Alzheimer’s Disease
The symptoms of the Alzheimer’s Disease vary from person to person; however, in general, they will follow a predictable pattern over the course of the disease. Realizing these symptoms, which are often divided into three major categories—the early, middle, and late stages—is important for the purpose of early detection and effective management.
Early-Stage Symptoms
- At its earliest stages, the symptoms of Alzheimer’s can be very subtle and perhaps easily mistaken for normal aging. Common early-stage symptoms include:
- Memory Loss: Forgetting recent events, names, or places; misplacing items regularly.
- Problem-Solving Difficulty: Difficulty following a plan or working with numbers; trouble handling finances.
- Mix-up about time or place: When one becomes mixed up about dates, seasons, or the passage of time and forgets where they are or how they got there.
- Difficulty in doing familiar things: Difficulty performing familiar daily chores like driving to a familiar destination or cooking a meal.
- Trouble with Words: Trouble in choosing the right words or following conversations.
- Poor judgment: Acting out of character with judgment, such as giving away lots of money or not bathing
- Mood and personality changes: Feeling more anxious, depressed, or easily upset
Middle-Stage Symptoms
As the Alzheimer’s Disease progresses to the middle stage, the symptoms become more pronounced and noticeable. The person may have entered this stage that can last for several years and require more intensive care. Common middle-stage symptoms include:
- Increased Memory Loss: Forgetting important details, such as their address, phone number, or the names of family members.
- Mixing Up the Identity of Friends and Relatives: Confusion about the identities of people they know very well.
- Behavioral Changes: Exhibiting delusions, paranoia, or suspiciousness; performing repetitive behavior or asking the same questions over and over.
- Sleep Problems: Difficulty sleeping at night or sleeping during the day and feeling restless at night.
- Increased Need for Assistance: Requiring help with dressing, bathing, or other personal care tasks.
- Language Decline: Gradual decline in language skills, leading to difficulty speaking, reading, or writing.
Late-Stage Symptoms
In the late stages of Alzheimer’s, a patient completely stops responding to their environment and communicating and cannot perform basic daily activities. Late-stage symptoms include:
- Severe Loss of Memory: Not being able to remember recent events or identify family members or friends.
- Loss of Physical Abilities: Difficulty in walking, sitting, or even swallowing.
- Inability to Communicate: Loss of the ability to speak coherently or to speak at all; the patient may just groan or moan.
- Complete Dependence: Completely dependent on others for help with all personal needs like eating, dressing, and toileting.
- Susceptibility to Infections: More susceptible to infections like pneumonia.
- Causes and Risk Factors of Alzheimer’s Disease
Age
Age is the most significant risk factor for Alzheimer’s Disease. The risk increases significantly after the age of 65, and the likelihood of developing the disease doubles approximately every five years after that age. However, Alzheimer’s is not a normal part of aging, and it can also occur in people under 65, known as early-onset Alzheimer’s.
Genetics
A family history of Alzheimer’s Disease can increase an individual’s risk, particularly if a parent or sibling has been diagnosed with the condition. Certain genes have been linked to Alzheimer’s, including the APOE-e4 gene, which is associated with an increased risk of late-onset Alzheimer’s. However, not everyone with these genes will develop the disease, indicating that other factors also play a role.
Brain Changes
Alzheimer’s Disease is characterized by the accumulation of abnormal proteins in the brain, including beta-amyloid plaques and tau tangles. Beta-amyloid plaques are clumps of protein that build up between nerve cells. While tau tangles are twisted fibers of another protein that form inside cells. These changes disrupt communication between neurons and lead to cell death.
