Getting older often means noticing small changes in how we think or remember. Misplacing keys, forgetting an appointment, or searching for the right word may feel concerning. Families often wonder: Is it forgetfulness or dementia?
The Alzheimer’s Association reports that over seven million Americans live with Alzheimer’s, the most common type of dementia. While that number is significant, it only accounts for about one in nine older adults.
The likelihood increases with age. About five percent of people between ages 65 and 74 have Alzheimer’s and/or dementia, 13.2 percent of people ages 75 to 84, and 33.3 percent of people 85 or older.
Understanding the difference between everyday forgetfulness and a possible dementia diagnosis helps families prepare for the future. At Pegasus Landing of Tanglewood in Houston, TX, we provide assisted living and the Connections memory care program to support seniors and families experiencing memory loss.
Normal Forgetfulness vs. Dementia
It is natural for memory to change with age. Older adults may take longer to recall a name, balance several tasks, or learn new technology. These changes do not usually interfere with independence.
Dementia, on the other hand, involves more severe problems that disrupt daily life. Families may notice repeated confusion, getting lost in familiar places, or forgetting important details, such as family members’ names.
As Dr. Sandra Petersen, Senior VP of Health and Wellness, explains:
“Alzheimer’s is not a normal progression of aging. Alzheimer’s results in a pervasive pattern of memory loss that drastically impairs function over time. Normal aging, on the other hand, may result in slower processing speed, slower word recall, and occasional forgetfulness.”
The Difference Between Forgetfulness and Dementia
The difference comes down to function. If memory lapses make life harder to manage, dementia may be present.
Examples of normal forgetfulness:
- Forgetting why you walked into a room, then remembering later
- Missing an appointment, but quickly rescheduling
- Needing more reminders or lists to stay organized
Examples of dementia-related memory loss:
- Forgetting how to complete familiar tasks, like cooking a regular meal
- Struggling to follow conversations or repeat questions often
- Misplacing objects and being unable to retrace steps
- Confusing time, place, or familiar people
Early Signs of Dementia
Identifying the early signs of dementia can give families more time to plan and seek support. Alzheimer’s Research UK notes the breakdown of dementia types:
- Alzheimer’s (60%)
- Vascular dementia (15%)
- Mixed dementia (10%)
- Dementia with Lewy Bodies (10%)
- Frontotemporal dementia (2%)
- Parkinson’s dementia (2%)
- Other types (1%)
Each condition has different causes, but they share warning signs:
- Trouble with memory, especially short-term recall
- Difficulty with planning or decision-making
- Language problems, like losing track of words
- Changes in mood, personality, or behavior
- Decline in ability to manage finances or household tasks
Types of Dementia Explained
Alzheimer’s
Alzheimer’s is the most common form of dementia. It typically begins with memory problems, such as forgetting recent conversations or events. As it progresses, it impacts reasoning, language, and independence. Families may also notice mood shifts or withdrawal.
Stages: Early memory lapses, followed by confusion and growing care needs, then severe decline with loss of communication and recognition.
Hallmark Quality: Persistent memory loss that makes it hard to form new memories.
Vascular Dementia
Vascular dementia results from reduced blood flow to the brain, often linked to strokes. Early signs include slower thinking, difficulty planning, and problems with focus.
Stages: Symptoms may progress suddenly after vascular events, creating a step-like decline.
Hallmark Quality: Trouble with problem-solving and organization, more than memory loss.
Mixed Dementia
Mixed dementia combines two or more types, often Alzheimer’s and vascular dementia. Symptoms overlap, with both memory loss and reasoning issues appearing together.
Stages: Progression varies but typically blends traits of the contributing types.
Hallmark Quality: A mix of symptoms that makes diagnosis and treatment more complex.
Dementia with Lewy Bodies
This type is linked to protein deposits in the brain. Families may notice vivid hallucinations, sleep problems, and sudden shifts in attention. Movement changes are also common.
Stages: Gradual decline, with fluctuations in awareness and mobility challenges.
Hallmark Quality: Early, detailed visual hallucinations.
Frontotemporal Dementia
Frontotemporal dementia affects the brain’s frontal and temporal lobes. Memory is often intact at first, but language problems, poor judgment, or personality changes emerge early.
Stages: Begins in midlife and progresses to include movement and cognitive decline.
Hallmark Quality: Dramatic behavior or speech changes, not memory loss.
Parkinson’s Dementia
Parkinson’s disease may lead to dementia later on. Symptoms include confusion, slowed thinking, and memory problems alongside tremors and stiffness.
Stages: Appears after years of Parkinson’s, with both cognitive and motor decline.
Hallmark Quality: Memory issues combined with movement difficulties.
Other Types of Dementia
Less common dementias can stem from conditions like Huntington’s or long-term alcohol use. Symptoms may include uncontrolled movements, rapid decline, or severe mood shifts.
Hallmark Quality: Unusual or rare features compared to more common forms of dementia.
Is it Dementia or Something Else?
Is It Dementia or Brain Fog?
Brain fog may occur during times of stress, lack of sleep, or as a side effect of medical treatment. Unlike dementia, brain fog often clears with rest or lifestyle changes. If confusion or forgetfulness continues and interferes with everyday life, dementia may be a concern.
Is It Depression or Dementia?
Depression can cause memory issues and a lack of focus, which sometimes looks like dementia. With treatment, these symptoms often improve. Dementia usually continues to worsen over time.
Is It Anxiety or Dementia?
Anxiety may lead to forgetfulness, especially when the mind is preoccupied with worry. Unlike dementia, anxious forgetfulness usually improves with treatment or stress management.
Is It ADHD or Dementia?
Some older adults live with undiagnosed ADHD. Difficulty concentrating, restlessness, or forgetfulness may mimic symptoms of dementia. A professional evaluation helps clarify the difference between ADHD and dementia.
What Tests Are Used to Measure Dementia?
Medical professionals use several cognitive dementia assessment measures to understand memory changes. These may include:
- Memory recall tests to check short-term memory
- Language assessments to measure naming, vocabulary, and fluency
- Problem-solving tasks to assess planning and decision-making
- Physical exams and lab work to rule out other conditions
The dementia FAST scale (Functional Assessment Staging Test) may also be used. It outlines seven stages of Alzheimer’s progression, from mild forgetfulness to severe impairment.
Professionals use measuring tools to determine the severity of dementia and create personalized care plans. Families may hear about the MMSE (Mini-Mental State Exam) or MoCA (Montreal Cognitive Assessment). Both test orientation, memory, and attention.
While online quizzes and at-home tests exist, only professional assessments provide reliable results.

Medical experts list more than five, but the top five account for nearly all diagnoses.
What tests are used to measure dementia?
Doctors may use memory and cognitive tests, medical history, and imaging scans to evaluate brain changes.
What are the early signs of dementia?
Forgetting recent events, struggling with daily tasks, personality changes, and language issues are some of the early signs.
Support for Families
Families often ask, “Is it dementia?” when memory changes appear. The answer requires careful evaluation by health care providers. It is essential to remember that not every lapse is indicative of dementia, but when changes significantly interfere with independence, professional guidance becomes crucial.
At Pegasus Landing of Tanglewood in Houston, TX, we provide resources and care for seniors experiencing memory changes. Through assisted living and the Connections memory care program, we support individuals living with Alzheimer’s and other types of dementia.
The Connections program, created by Dr. Sandra Petersen, uses a “Connect-Move-Learn” method to help build new brain pathways, even when memory loss occurs. Music therapy, exercise, brain games, and memory-building activities are included. Families also receive support through educational groups and ongoing guidance.
