What Is Alzheimer's Disease? Symptoms and Stages

Alzheimer’s disease is a progressive illness that occurs as nerve cells in the brain become damaged over time, increasingly affecting memory, thinking skills and daily life activities. Being the most common cause of dementia, Alzheimer’s increases in frequency with age but is a medical condition requiring diagnosis and monitoring, and cannot simply be explained as “a natural result of aging.”

What Is Alzheimer’s Disease?

Alzheimer’s develops as a result of abnormal protein structures accumulating in the brain, disrupting communication between nerve cells. This process starts with memory and, over time, also affects language, orientation, decision-making and daily functions. The illness progresses slowly over the years; this is why early recognition matters, both for medical monitoring and family planning to start in time.

What Are the Early Symptoms?

Forgetting recently learned information, asking the same questions repeatedly, having difficulty finding everyday items, and being indecisive while doing familiar tasks are among the common early symptoms. These symptoms may initially be mild and hard to notice; over time, difficulties with planning, finding words, and time-space perception are added.

The Stages of Alzheimer’s

Alzheimer’s generally progresses in three stages: mild, moderate and advanced. In the mild stage, forgetfulness and difficulty finding names/words are prominent, and the person can largely continue their daily life. In the moderate stage, memory loss becomes more pronounced, and the need for support with daily activities (such as dressing and preparing meals) increases. In the advanced stage, comprehensive and continuous support is needed for communication, mobility and self-care. Each individual passes through these stages at a different pace, which is why the care plan must also be updated in a personalized way.

The Difference Between Normal Forgetfulness and Alzheimer’s

Forgetting where you put your keys and then remembering is a normal sign of aging, while asking the same question repeatedly at short intervals or getting lost on a familiar route are signs that require a more detailed assessment. The extent to which the symptoms affect daily life is the most decisive difference between normal forgetfulness and Alzheimer’s.

When Should You Consult a Specialist?

If forgetfulness starts to disrupt daily tasks, if there are noticeable changes in personality and behavior, or if the family has concerns about this, it would be right to consult a neurology or geriatrics specialist. Early diagnosis allows treatment and care planning to start in time.

The Care Approach for Alzheimer’s Patients

Care during the Alzheimer’s process requires a personalized approach that brings together a consistent routine, patient communication and a safe environment. We covered our detailed approach on this topic in our article What Should the Right Approach to Alzheimer’s and Dementia Care Be?. At GAYA Huzurevi’s 5 branches, we offer our Alzheimer’s and dementia care service with our expert nurse-doctor staff.

Frequently Asked Questions

Is Alzheimer’s a normal condition seen in old age?

No, Alzheimer’s is a medical illness that increases in frequency with age but requires diagnosis and monitoring; it should not be considered a part of normal aging.

What is the difference between Alzheimer’s and dementia?

Dementia is a general name given to a group of symptoms affecting memory and thinking skills; Alzheimer’s is the most common cause of dementia. We covered this difference in detail in our article on what dementia is and how it differs from Alzheimer’s.

What should be the first step after an Alzheimer’s diagnosis?

Alongside creating a treatment and monitoring plan with a specialist, it’s important for the family to also learn how the care needs may progress; at this point we can call and evaluate the process together.

When should a nursing home be considered for an Alzheimer’s patient?

When the daily care need exceeds the level the family can safely handle at home, an institutional care environment offering 24/7 expert supervision can be considered.
