Question 1

What is the primary characteristic of Alzheimer's disease?

Accepted Answer

Progressive memory loss and cognitive decline

Answer

Alzheimer's disease is primarily characterized by a progressive and continuous decline in memory and other cognitive functions, such as thinking and reasoning. Unlike sudden or temporary confusion, it involves a gradual neurodegenerative process that worsens over time. This progressive nature is a defining feature distinguishing it from other forms of memory impairment.

Question 2

Which protein abnormality is commonly associated with Alzheimer's disease?

Accepted Answer

Beta-amyloid plaques and tau tangles

Answer

The hallmark pathological features of Alzheimer's disease are the accumulation of abnormal protein deposits in the brain: beta-amyloid plaques and tau tangles. Beta-amyloid plaques are clumps of protein fragments found outside neurons, while neurofibrillary tangles are twisted fibers of tau protein found inside neurons. These abnormalities disrupt brain cell function and communication, leading to cognitive decline.

Question 3

Which of the following is a common early symptom of Alzheimer's disease?

Accepted Answer

Short-term memory loss

Answer

One of the most common and earliest symptoms of Alzheimer's disease is short-term memory loss, specifically difficulty remembering recently learned information. This can manifest as forgetting names, recent conversations, or events, and repeatedly asking the same questions. Long-term memories are typically preserved until later stages of the disease.

Question 4

Which diagnostic method is commonly used to support Alzheimer's diagnosis?

Accepted Answer

Neuroimaging like MRI or PET

Answer

Neuroimaging techniques, such as Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) scans, are commonly used to support an Alzheimer's diagnosis. MRI can detect brain shrinkage and rule out other causes of cognitive decline, while PET scans can identify amyloid plaques, tau tangles, or show reduced brain metabolism characteristic of the disease. These methods help confirm the presence of changes associated with Alzheimer's.

Question 5

What is the main goal of treatment in Alzheimer's disease?

Accepted Answer

To slow cognitive decline and manage symptoms

Answer

Currently, there is no cure for Alzheimer's disease. Therefore, the main goal of treatment is to slow the progression of cognitive decline and manage the behavioral and psychological symptoms associated with the disease. Medications and non-pharmacological interventions aim to improve quality of life and help individuals maintain independence for as long as possible.
