Alzheimer’s disease is one of the most common neurodegenerative disorders affecting millions of people worldwide, especially older adults above 60 years of age. It gradually impacts memory, behavior, cognitive function, and the ability to perform everyday tasks. As life expectancy increases, Alzheimer’s disease has become a major health concern for families and healthcare professionals across the globe.
This blog explains Alzheimer’s symptoms, causes, stages, diagnosis, treatment approaches, and how timely rehabilitation and caregiving support can improve the quality of life for patients.
What Is Alzheimer’s Disease?
Alzheimer’s disease is a progressive brain disorder that slowly destroys memory, thinking skills, and the ability to carry out simple tasks. It is the most common form of dementia, accounting for 60–80% of dementia cases. Over time, brain cells shrink and die, leading to significant memory loss, personality changes, confusion, and decline in daily functioning.
Key Symptoms of Alzheimer’s Disease
The symptoms usually start mildly and become severe over the years. Common signs include:
1. Memory Loss
Forgetting recent conversations
Misplacing everyday items
Repeating the same questions
Difficulty remembering names, dates, or appointments
2. Poor Judgment & Decision-Making
Patients may struggle with money management, driving skills, or choosing appropriate clothing.
3. Difficulty in Communication
Trouble finding the right words, following conversations, or understanding instructions.
4. Changes in Behavior & Personality
Irritability
Anxiety
Depression
Mood swings
Social withdrawal
5. Disorientation
Confusion about places, time, or familiar surroundings.
6. Difficulty in Daily Tasks
Struggling with cooking, bathing, dressing, or household chores.
Causes of Alzheimer’s Disease
The exact cause is still unknown, but several factors increase the risk:
🔹 Age:
Most common after age 60.
🔹 Genetics & Family History:
If a parent or sibling has Alzheimer’s, the risk increases.
🔹 Brain Changes:
Deposits of amyloid plaques and tau tangles damage brain cells.
🔹 Lifestyle Factors:
Poor diet, smoking, stress, lack of exercise, and high blood pressure.
🔹 Medical Conditions:
Diabetes, cardiovascular disease, head injuries, and obesity.
Stages of Alzheimer’s Disease
Alzheimer’s disease progresses in three main stages:
1. Early Stage (Mild)
Minor memory loss
Difficulty doing complex tasks
Mood changes
2. Middle Stage (Moderate)
Increased confusion
Sleep disturbances
Behavioral issues
Needing help with daily activities
3. Late Stage (Severe)
Severe memory loss
Difficulty swallowing
Loss of mobility
Full-time care required
Diagnosis of Alzheimer’s Disease
Doctors use several evaluations, including:
Medical history
Neurological examination
Memory and cognitive tests
MRI or CT brain scans
Blood tests
Neuropsychological assessments
Early diagnosis helps start treatment early and improves long-term care planning.
