Differences Between Dementia and Alzheimer's

Alzheimer and Genetic Relationship

While there is no distinct cause for Alzheimer's, genetics can play a significant role. Researchers are particularly interested in the Apolipoprotein E (APOE) gene, associated with the onset of Alzheimer's symptoms in older adults.

Blood tests can determine if you carry this gene, increasing your risk. However, having the gene does not guarantee you will get Alzheimer's.

Conversely, someone without the gene may still develop Alzheimer's. For now, it's uncertain whether someone will develop Alzheimer's.

Other genes can also increase the risk of Alzheimer's and early-onset Alzheimer's.

Symptoms of Alzheimer's Disease

Everyone experiences forgetfulness from time to time, but people with Alzheimer's display worsening behaviors and symptoms over time. These may include:

– Memory loss affecting daily activities, such as keeping appointments.
– Difficulty with familiar tasks, like using a microwave.
– Challenges with problem-solving.
– Trouble with speech or writing.
– Disorientation about times or places.
– Decreased judgment.
– Decreased personal hygiene.
– Mood and personality changes.
– Withdrawal from friends, family, and community.

Symptoms vary according to the disease stage.
