Alzheimer’s vs Dementia: What’s the Difference

Donna Nichols • September 7, 2021

Dementia is the term for a decline in mental ability severe enough to interfere with daily life.

Alzheimer’s is the most common cause of dementia.

Alzheimer’s is a specific disease. Dementia is not a disease.

What's the difference between alzheimer's and dementia

What is Dementia

Dementia represents symptoms associated with a decline in memory, reasoning or other thinking skills. There are many types of dementia and many factors lead to its cause. Mixed dementia is a condition in which brain changes of more than one type of dementia occur at the same time.

Dementia is not a normal part of aging.

It is caused by damage to brain cells that affects their ability to communicate, which can affect thinking, behavior and feelings.

A disorder grouped as dementia is caused by abnormal brain changes; these changes cause a decline in thinking skills severe enough to interfere with your daily life and independence. These changes also affect your behaviors, feelings and relationships.

Before dementia was understood as it is now, which still isn’t very good, is was considered a normal aging process and referred to as senile. Dementia is NOT a normal aging process, so if you notice any signs and symptoms, please seek medical attention immediately.

Signs of dementia can vary greatly. Examples include:

  • Problems with short-term memory.
  • Keeping track of a purse or wallet.
  • Paying bills.
  • Planning and preparing meals.
  • Remembering appointments.
  • Traveling out of the neighborhood.

Many conditions start out slowly and gradually get worse. If you do find yourself at the point of having to place your loved one in a memory care facility please don’t hesitate to give us a call. 

If you or someone you know is experiencing memory difficulties or other changes in thinking skills, don’t ignore them!

Early detection is key!

Explaining Alzheimer’s

Alzheimer’s disease is the most common cause of dementia, accounting for 60-80% of dementia cases.

Alzheimer’s is a degenerative brain disease that is caused by complex brain changes following cell damage.

It leads to dementia symptoms that gradually worsen over time.

The most common early symptom of Alzheimer’s is trouble remembering new information because the disease usually targets the part of the brain related to learning first.

As Alzheimer’s advances, symptoms get more severe and include disorientation, confusion and behavior changes. Eventually, speaking, swallowing and walking become difficult.

Though the greatest known risk factor for Alzheimer’s is aging, the disease is not a normal part of getting older. And although most people with Alzheimer’s are 65 and older, younger-onset Alzheimer’s has become more prevalent with approximately 200,000 Americans under 65 years-old suffering.

Signs of Alzheimer’s disease are:

  • Memory loss that disrupts daily life
  • Challenges in planning or solving problems
  • Difficulty completing familiar tasks
  • Confusion with time or place
  • Trouble understanding visual images and spatial relationships
  • New problems with words in speaking or writing
  • Misplacing things and losing the ability to retrace steps
  • Decreased or poor judgment
  • Withdrawal from work or social activities
  • Changes in mood and personality

If you notice any of the symptoms in yourself or someone you know, PLEASE seek the help of a medical professional!! Early detection is the KEY!!

If you are caring for someone suffering with Alzheimer’s or a related dementia, we hold 3 caregiver support groups a month. Please don’t go it alone, we are here for you!!

If you’ve ever walked into a room full of older adults and noticed the sweaters, shawls, and space heaters humming in the corner, you’re not imagining it — many seniors really do feel colder than everyone else. And it’s not just a quirk. There are real, physical reasons behind it, and understanding them can make daily life a lot more comfortable. 1. Our Internal Thermostat Changes Over Time As we age, the body becomes less efficient at regulating temperature. The internal “thermostat” in the brain doesn’t respond as quickly to cold, so seniors may feel chilly even when the room is warm enough for others. 2. Less Muscle = Less Heat Muscle mass naturally decreases with age, and muscle is what helps generate body heat. With less of it, the body simply produces less warmth. Even active seniors may notice they get cold more easily than they used to. 3. Thinner Skin and Reduced Circulation Skin becomes thinner over time, offering less insulation. On top of that, circulation often slows, meaning warm blood takes longer to reach hands, feet, and other extremities. This is why fingers and toes are often the first to feel icy. 4. Medications Can Play a Role Many common medications — including those for blood pressure, thyroid issues, or depression — can affect how warm or cold someone feels. It’s not always the medication itself, but how it interacts with the body’s temperature signals. 5. Underlying Health Conditions Conditions like anemia, diabetes, thyroid disorders, or poor circulation can all contribute to feeling cold. Sometimes, persistent chilliness is the body’s way of asking for a check-in with a healthcare provider. 6. Hydration and Nutrition Matter More Than You Think Dehydration and low-calorie intake can both make the body feel colder. Seniors who don’t drink enough water or who eat lightly may notice they’re chilly more often. Simple Ways to Stay Warm and Comfortable • Layer up with breathable fabrics • Keep moving — even gentle stretching boosts circulation • Warm beverages throughout the day • Use blankets or heated throws safely • Check room drafts and adjust thermostat settings • Talk with a doctor if coldness is new or worsening A Warm Note to Close Feeling cold isn’t a sign of weakness — it’s a natural part of aging. With a few small adjustments and a little awareness, seniors can stay cozy, comfortable, and confident all year long.

Spring has a way of softening the world. The air warms, the light lingers, and suddenly the small things — a bird call, a new bloom, a gentle breeze — feel like invitations to breathe a little deeper. For many seniors, especially those carrying grief, stress, or the weight of a long winter, March can feel like a quiet turning point. Here’s why spring so often brings emotional renewal, no matter your age. 1. Light Returns, and So Does Energy Longer days naturally lift mood. More sunlight helps regulate sleep, boosts energy, and gently nudges the body out of winter’s heaviness. Even a few minutes outside can shift the way the day feels. 2. Nature Models Healing Spring is a season of second chances. Trees bud again, flowers push through the soil, and the world rebuilds itself without rushing. For seniors navigating loss or change, this slow, steady renewal can feel reassuring — a reminder that healing isn’t linear, but it is possible. 3. Movement Feels More Natural Warmer weather encourages small steps: a walk to the mailbox, a few minutes on the porch, tending to a plant. These simple movements help ease stiffness, improve mood, and reconnect the body with the world around it. 4. Social Life Blossoms Too As the weather improves, people naturally come out of hibernation. Neighbors chat outside, community events pick up, and families gather more often. Even brief interactions can brighten a day and reduce feelings of isolation. 5. Spring Encourages Reflection — and Release There’s something about fresh air and open windows that invites a mental reset. Many seniors find themselves sorting through memories, letting go of what no longer serves them, and making space for what’s next. A Season That Meets You Where You Are Spring doesn’t demand big changes. It simply offers gentle reminders: you’re still growing, still healing, still here. Whether you’re grieving, rebuilding, or simply ready for a lighter season, March brings a quiet kind of hope — one that arrives softly and stays.
