What Is Alzheimer’s Disease? Early Symptoms, Causes, and Diagnosis Explained
What is Alzheimer’s disease, and how is it different from normal aging? Alzheimer’s disease is the most common cause of dementia, affecting memory, thinking, language, and eventually the ability to perform everyday activities.
In this video, Dr. Amarish Dave, DO, Board-Certified Neurologist, explains what happens inside the brain during Alzheimer’s disease, why memory loss develops, and how doctors recognize the early warning signs.
You’ll learn:
* What Alzheimer’s disease is and how it affects the brain.
* How amyloid-beta plaques and tau tangles are involved in Alzheimer’s disease.
* Why short-term memory loss is often an early symptom.
* The difference between normal aging, mild cognitive impairment (MCI), and dementia.
* Other symptoms, including confusion, difficulty finding words, and changes in judgment.
* How neurologists evaluate memory loss using cognitive testing, blood tests, brain imaging, and, when appropriate, Alzheimer’s biomarkers.
* Why early diagnosis matters.
Is Alzheimer’s disease the same as dementia?
No. Dementia describes a syndrome involving cognitive decline that interferes with independence. Alzheimer’s disease is a specific brain disorder and the leading cause of dementia.
In Part 2, we explain how Alzheimer’s disease is treated, including medications, newer anti-amyloid therapies, exercise, nutrition, hearing care, sleep, and social engagement.
