Top Questions About Dementia and Alzheimer’s
Whether you’re wondering, “Can dementia run in the family?”, “Is memory loss hereditary?”, or “How do I help my loved one with Alzheimer's?” we have the answers for you below.
1. Dementia vs. Alzheimer’s: What’s the Difference?
It’s common to hear the terms “dementia” and “Alzheimer’s” used interchangeably, but they aren’t the same thing.
Dementia is a general term that refers to a decline in cognitive abilities severe enough to interfere with daily life. It’s not a specific disease but rather an umbrella term encompassing various conditions that cause memory loss, difficulty with problem-solving, language impairments, and changes in behavior. Some of the most common types of dementia are Alzheimer's, Lewy Body Dementia, and Vascular Dementia.
Alzheimer’s disease, on the other hand, is a specific type of dementia that accounts for 60-80% of all dementia cases. Alzheimer’s is a progressive neurological disorder that primarily affects memory and cognitive function.
2. What Causes Dementia and Alzheimer’s?
Dementia and Alzheimer’s disease are complex conditions. While they share some overlapping risk factors, the specific causes of each condition differ.
Causes of Dementia
Dementia is an umbrella term for various conditions that impair memory, thinking, and behavior. It results from damage to brain cells that disrupts their ability to communicate effectively. Common causes include vascular damage, abnormal protein deposits, and brain injuries.
Causes of Alzheimer’s Disease
Alzheimer’s disease is a specific type of dementia characterized by progressive memory loss and cognitive decline. Its causes include:
Abnormal proteins: Alzheimer’s is associated with abnormal protein deposits in the brain, disrupting brain function and leading to cell death.
Genetics: Certain genes are known to increase the risk of Alzheimer’s.
Age and Brain Changes: Aging is the biggest risk factor, as the brain undergoes changes over time, such as shrinkage, inflammation, and reduced repair mechanisms.
Unhealthy Lifestyle: Poor health and pre-existing health conditions can also increase your risk for Alzheimer’s.
While health professionals don’t fully understand all the mechanisms behind these conditions, ongoing research continues to uncover insights. Making lifestyle changes, such as improving cardiovascular health and staying mentally active, can reduce the likelihood of developing dementia or Alzheimer’s later in life.
3. Does Dementia Run in Families?
So, is Alzheimer’s genetic? What about dementia? Is it hereditary?
The answer is both “yes” and “no.”
The “yes” is that a familial history of memory loss can be an indication of increased risk for dementia or Alzheimer’s. The answer to the question “Is Alzheimer’s or dementia inherited from the mother or father?” is that it appears to be more strongly associated with the mother’s side than the father’s. Additionally, recent research has identified specific genes that may increase the likelihood of developing dementia or Alzheimer’s. Genetic testing for Alzheimer’s is available for individuals who are concerned about their genetic risk and wish to gain more insight.
However, the “no” to “Is Alzheimer’s or dementia inherited?” means that other factors can also contribute to an increased risk of memory loss diseases, like age, lifestyle, and overall health. Even if you have Alzheimer’s genes or your mother has dementia or Alzheimer’s, there’s still no guarantee that you will get it. Engaging in regular physical activity, maintaining a balanced diet, and keeping the mind active can help reduce the risk of developing dementia or Alzheimer’s.
The key point about Alzheimer’s and dementia being hereditary is that while having a family member with dementia might raise your risk, it doesn’t mean the condition is unavoidable. No matter your family history, embracing a healthy lifestyle can play a significant role in reducing your chances of developing Alzheimer’s or dementia.
4. What Are Early Signs of Alzheimer’s and Dementia?
Recognizing the early signs of dementia or Alzheimer’s can help in receiving the right support and planning for the future. Here are some of the most common early symptoms that can be a sign of dementia or Alzheimer’s:
Memory loss that disrupts daily life
Difficulty planning or solving problems
Confusion with time or familiar places
Trouble with familiar tasks
Changes in mood or personality
Misplacing things and forgetting where they are
If you or a loved one is experiencing any of these symptoms, you should consult a doctor for a thorough mental and physical evaluation.
