Brian Callahan 7 Day Home Care • June 18, 2025

Did you know that according to Neuroscience News a recent study found a genetic variant - H63D in the HFE gene - more than doubles the risk of dementia in older men? Researchers analyzing data from over 12,000 Australians aged 70 and above discovered that men carrying two copies of this variant were 2.39 times more likely to develop dementia compared to those without it.


News headlines, firsthand caregiving experiences, and new research studies about dementia often spark a wave of urgent and sometimes overwhelming questions for families. Whether it’s a scientific breakthrough linking a gene to increased dementia risk, or a viral story about a family’s caregiving journey, these real-world moments prompt people to wonder: What are the early signs? Could this happen to my loved one? How do we get help? As awareness grows, so does the need for clear, trustworthy information. That’s why understanding the top questions people ask about dementia is more important than ever—for families, caregivers, and anyone navigating the complex journey of memory loss.

It's Common to Have Questions About Dementia

Dementia is a broad and complex condition that affects millions of families across the United States. Whether you’re caring for a loved one, seeking a diagnosis, or exploring long-term care options, it’s common to have questions. At 7 Day Home Care, we’re proud to be a trusted provider of dementia care in New York. This article answers the top 20 most frequently asked questions about dementia—offering clarity, guidance, and peace of mind.



1. What is dementia?

Dementia is not a single disease—it’s an umbrella term that describes a decline in memory, thinking, behavior, and the ability to perform everyday activities. Alzheimer’s disease is the most common type of dementia.


2. What are the early signs of dementia?

Early signs include memory loss, difficulty finding words, confusion, poor judgment, trouble with problem-solving, mood changes, and getting lost in familiar places.


3. What causes dementia?

Dementia is caused by damage to brain cells. This damage interferes with the ability of brain cells to communicate, which can affect thinking, behavior, and feelings. Causes include Alzheimer’s disease, vascular issues, Lewy body dementia, frontotemporal dementia, and head injuries.


4. Is dementia the same as Alzheimer’s?

No. Alzheimer’s disease is a type of dementia. It accounts for 60–80% of dementia cases but is just one of many forms.


5. Can dementia be cured?

There is currently no cure for dementia, but treatments can help manage symptoms, especially in the early stages. Medications and therapies can improve quality of life.


6. How is dementia diagnosed?

Doctors diagnose dementia through a combination of medical history, physical exams, cognitive tests, brain imaging (like MRI or CT scans), and bloodwork to rule out other conditions.


7. What is the difference between dementia and normal aging?

Normal aging may involve some forgetfulness, but dementia significantly interferes with daily life. Dementia causes persistent problems with memory, communication, and reasoning.


8. How fast does dementia progress?

The rate of progression varies. Alzheimer’s typically progresses over 8–10 years, but the speed depends on the type of dementia and the individual’s overall health.


9. What are the stages of dementia?

Dementia is often categorized into three stages:

  • Early (Mild): Memory loss, confusion, disorientation
  • Middle (Moderate): Increased memory loss, difficulty with personal care, behavioral changes
  • Late (Severe): Inability to communicate, total dependence on caregivers


10. Is dementia hereditary?

Some types of dementia have a genetic component, but most cases are not inherited. Genetics may increase risk, but lifestyle and overall health also play major roles.


11. What can I do to lower my risk of dementia?

Maintaining a healthy lifestyle can reduce your risk:

  • Regular exercise
  • Healthy diet (like the Mediterranean diet)
  • Cognitive stimulation
  • Social engagement
  • Managing blood pressure, cholesterol, and diabetes
  • Avoiding smoking and excessive alcohol


12. What should I do if I think my loved one has dementia?

Schedule a medical evaluation as soon as possible. Early diagnosis allows for treatment, planning, and support services that can improve outcomes.


13. How can I communicate better with someone who has dementia?

Use simple, clear language. Be patient. Avoid arguing or correcting. Make eye contact and use non-verbal cues. Speak slowly and with reassurance.


14. What are common behavioral changes in dementia?

People with dementia may experience:

  • Agitation
  • Aggression
  • Anxiety or depression
  • Wandering
  • Sleep disturbances
  • Delusions or hallucinations

Understanding these behaviors as symptoms—not personal attacks—can help with more compassionate caregiving.


15. Can people with dementia live at home?

Yes. Many individuals with dementia live safely at home with the support of family caregivers and professional home care agencies like 7 Day Home Care. In-home care allows for familiar surroundings and personalized support.


16. What is in-home dementia care?

In-home dementia care involves trained caregivers assisting with:

  • Activities of Daily Living (ADLs) such as bathing, dressing, and eating
  • Medication reminders
  • Supervision for safety
  • Mobility assistance
  • Companionship and cognitive engagement
  • Fall prevention and nighttime monitoring


17. What is the role of a professional caregiver?

A professional caregiver helps individuals with dementia stay safe and independent at home. At 7 Day Home Care, our caregivers are trained in dementia care and supervised by registered nurses. We match caregivers based on personality, language, and culture to ensure comfort and trust.


18. How do I pay for dementia care?

Options include:

  • Long-term care insurance
  • Private pay
  • Medicaid (if eligible)
  • Veterans benefits

7 Day Home Care helps families navigate these options and works with many insurance providers to ease the financial burden.


19. How do I know when it’s time for home care?

If your loved one:

  • Struggles with daily tasks
  • Is at risk of falls or wandering
  • Forgets to take medications
  • Experiences mood swings or confusion
  • Shows signs of caregiver burnout

... it may be time to seek professional help. Early intervention leads to better outcomes.

Why Cancer Spreads Despite Treatment: How It Reprograms Your Body's Support System Cancer spreads despite treatment because it doesn’t act alone — it reprograms the healthy cells, tissues, and immune defenses around it to form what doctors call the tumor microenvironment . Instead of fighting cancer, nearby fibroblasts, blood vessels, and immune cells are “hijacked” to feed the tumor, deliver oxygen, and even shield it from the immune system’s attack. This support network also helps cancer create escape routes through new blood vessels, allowing it to spread to distant organs. Because cancer changes the very environment in which it grows, simply shrinking or removing the main tumor may not be enough - the surrounding support system must also be dismantled. This is why modern treatment often combines surgery, chemotherapy, immunotherapy, and targeted drugs that block blood vessel growth or “wake up” immune cells, giving patients a better chance to stop cancer from coming back. For cancer patients and their families, having a professional home care agency like 7 Day Home Care can dramatically improve quality of life and treatment outcomes. Our certified home health aides, supervised by experienced registered nurses, are specially trained in in-home ca ncer care, meaning they can safely manage medication schedules, monitor for side effects, and recognize early signs of infection or complications. This level of support reduces avoidable hospital visits, keeps treatment on track, and provides peace of mind for family caregivers. In addition, our team helps with daily activities, prepares nutrient-rich meals tailored to treatment needs, and ensures a safe home environment that minimizes fall risk. Emotional well-being is just as important as physical health, which is why our caregivers offer companionship and education, helping families feel confident and supported through every stage of treatment. Choosing highly experienced home care means patients can live and recover in the comfort of their own homes, surrounded by loved ones, while receiving professional oversight that aligns with their oncologist’s plan - a powerful combination for healing and hope.

Social Isolation and Dementia: Protection Guide Planning ahead to manage loneliness and dementia risk offers enormous benefits for families, both emotionally and practically. By creating a proactive social engagement plan early — before severe cognitive decline sets in — families can help their loved ones maintain memory, communication skills, and independence for longer, which can delay the need for facility-based care. Early planning allows families to set up routines, identify meaningful activities, and arrange professional companionship or home care services that keep seniors connected and mentally stimulated. This foresight not only improves the senior’s quality of life and emotional well-being but also reduces caregiver stress, prevents crisis-driven decisions, and minimizes costly hospitalizations. Getting ahead of social isolation is one of the most powerful steps families can take to protect brain health and preserve dignity for aging loved ones.

Does Alcohol Cause Dementia? Everything You Need to Know Yes, alcohol is a toxin that directly damages brain cells, accelerates brain aging, and significantly increases the risk of dementia. Research confirms that drinking alcohol - whether heavy, moderate, or even light - shrinks brain volu me, disrupts memory pathways, and worsens cognitive decline, especially in seniors. Over time, this toxic substance causes irreversible brain damage, raising the likelihood of Alzheimer’s disease, vascular dementia, and alcohol-related dementia. Now that you know the science, why continue drinking a chemical that poisons your brain? Your wealth is your health, and yet many people take better care of their cars, phones, and homes than they do of their own bodies and minds - when in truth, your brain is the most valuable possession you’ll ever have.

How Dementia Alters Perception: Sensory Distortions of Sights, Sounds, and Space
By Brian Callahan 7 Day Home Care August 11, 2025
Hidden Effects of Dementia: How the Brain Distorts Sights, Sounds, and Spaces Sensory distortions in dementia patients are often an overlooked and underappreciated aspect of the condition, leaving many caregivers unprepared for the challenges that arise. These distortions—ranging from visual and auditory hallucinations to misperceptions of space and time—can make daily tasks and interactions increasingly difficult for both the patient and their caregivers. For example, a person with dementia might see objects or people that aren’t there, or hear voices when no one is speaking, leading to confusion and distress. Without a clear understanding of these sensory changes, caregivers may inadvertently escalate anxiety or frustration by dismissing the patient’s experiences as mere confusion. Having a comprehensive understanding of these sensory distortions equips caregivers with the knowledge to manage these symptoms with compassion, patience, and effective strategies. It enables them to anticipate and address challenges, creating an environment that fosters comfort and safety. The better caregivers are informed about the sensory effects of dementia, the more they can provide personalized care that enhances the patient’s well-being and quality of life. This knowledge not only reduces the emotional and physical strain on caregivers but also helps ensure the patient feels seen, heard, and supported in a world that may increasingly feel distorted and unpredictable.
