World Alzheimer’s Month: Signs, Symptoms, and Early Detection

Forgetting a name, misplacing your keys, or walking into a room and wondering why you went there can happen to anyone. But when memory or thinking changes begin to interfere with everyday life, they deserve attention.

Each September, World Alzheimer’s Month encourages families to talk more openly about dementia, recognize possible warning signs, and seek help sooner. In 2026, the campaign emphasises early diagnosis and the opportunities it can create for treatment, planning, support, and informed decision-making.

Noticing a change does not mean assuming the worst. It means giving yourself or someone you love the chance to understand what is happening and what support may help.

Understanding Alzheimer’s Disease and Dementia

Alzheimer’s disease and dementia are related, but they are not the same thing.

Dementia is a general term for changes in memory, thinking, communication, or behavior that are significant enough to affect daily life. Alzheimer’s disease is the most common cause of dementia and may account for around 60% to 70% of dementia cases worldwide.

Alzheimer’s is a progressive brain disease, which means symptoms generally become more noticeable over time. Memory problems are common, but early changes can also affect language, judgment, problem-solving, mood, and visual or spatial awareness.

No two people experience the disease in exactly the same way. That’s why it is important to look for changes from a person’s usual abilities, not simply whether they occasionally forget something.

Early Signs and Symptoms to Pay Attention To

Some changes may be subtle at first. A family member may notice them before the person experiencing them does.

Memory Changes That Affect Daily Life

Occasional forgetfulness is common. More concerning changes may include:

Repeatedly asking the same question
Forgetting recently learned information
Missing important appointments more often
Relying heavily on notes or family members for things previously managed independently

The key difference is whether memory changes are beginning to interfere with everyday routines.

Difficulty Planning or Solving Problems

Tasks that once felt familiar may become harder. For instance, someone may have trouble:

Following a recipe
Managing household bills
Keeping track of medication
Working through several steps of a familiar task
Concentrating for long periods

These changes may appear gradually and should be considered in the context of the person’s usual abilities.

Problems With Familiar Tasks

A person might become confused during activities they typically do many times, like making a familiar meal, operating household appliances, or driving to a known destination.

VNA Health Group recommends that families watch for signs like unusual forgetfulness, confusion, getting lost in familiar places, or trouble following conversations, especially when these behaviors are new or noticeably different.

Changes in Language or Conversation

Occasionally searching for a word can happen at any age. A more persistent change may involve:

Losing track of a conversation
Repeating phrases
Struggling to name familiar objects
Using unusual words in place of common ones
Having increasing difficulty expressing a thought

The National Institute on Aging notes that word-finding difficulty can be one of the earliest cognitive changes associated with Alzheimer’s disease.

Confusion About Time or Place

Someone may lose track of dates, seasons, or the passage of time. They may become disoriented in a familiar neighborhood or forget how they got there.

Confusion can stem from various causes, especially when it appears suddenly. A sudden change in awareness or thought processes needs immediate medical attention, as it could indicate an infection, medication side effect, stroke, or other health issues.

Changes in Judgment, Mood, or Behavior

Alzheimer’s does not affect memory alone.

Early changes may include:

Poorer judgment with money or personal decisions
Withdrawal from hobbies or social activities
Increased anxiety or irritability
Changes in personality
Less interest in people or activities that once mattered

The World Health Organization notes that changes in mood and behavior can sometimes appear even before obvious memory problems.

What Is Normal Aging and What May Need Attention?

It can be difficult to know when a change is simply part of getting older.

Aging may bring occasional forgetfulness, slower recall, or a need for more time to learn something new. You might forget a name and remember it later, or miss an appointment only to realize it later.

A warning sign is more likely to affect daily functioning or represent a clear change from the person’s usual behavior.

For example:

Normal aging: Occasionally misplacing keys.
Possible concern: Repeatedly placing items in unusual locations and being unable to retrace steps.
Normal aging: Occasionally forgetting a word.
Possible concern: Frequently struggling to follow or join conversations.
Normal aging: Making an occasional mistake with a bill.
Possible concern: Losing the ability to manage finances that were previously handled independently.

Memory concerns do not automatically mean Alzheimer’s. Sleep problems, depression, medication side effects, thyroid disorders, vitamin deficiencies, infections, and other health conditions can also affect thinking and memory.

That is why medical evaluation matters.

Why Early Detection Can Make a Difference

Seeking help early can provide something families often need most: clarity.

Early evaluation may help identify whether symptoms are related to Alzheimer’s, another form of dementia, or a different medical condition. It can also give individuals and families more time to discuss preferences and make decisions together. Benefits may include:

Earlier access to appropriate treatment
Support for managing symptoms
Time to plan future care
Financial and legal planning
Opportunities to discuss driving and home safety
Access to education and caregiver support
Greater involvement of the person experiencing the changes

The Alzheimer’s Association notes that early diagnosis can improve access to care and support and may reduce some of the emotional and financial burden associated with the disease.

The science of early detection is also changing. Advances in imaging, cognitive assessment, and blood-based biomarkers are helping clinicians identify Alzheimer’s-related changes earlier than in the past. These tools aren’t appropriate for everyone, so make testing decisions with a qualified healthcare professional.

What Happens During an Alzheimer’s Evaluation?

An evaluation may include:

A review of memory and thinking changes
Medical and family history
Medication review
Cognitive or memory testing
Physical and neurological examinations
Blood or other laboratory tests
Brain imaging when appropriate
Additional testing or specialist referral

Bringing a trusted family member can be helpful. They may be able to describe changes that have developed gradually or provide examples from daily life.

If leaving home for medical appointments has become difficult, VNA Health Group’s Visiting Physician Services can help eligible patients access medical care in the home. VNA’s visiting physician program includes evaluations and management for Alzheimer’s disease, dementia, and other chronic health conditions.

Supporting a Loved One After a Diagnosis

A diagnosis can bring many emotions, including fear, relief, grief, or uncertainty. Families do not have to make every decision immediately.

Begin with what the person needs today.

That may mean simplifying routines, reviewing medications, making the home easier to navigate, or arranging additional supervision. VNA Health Group’s guide to adapting the home for someone with dementia includes practical ways to support safety while preserving familiarity and independence.

Caregivers may need support as well. For eligible families in Monmouth County, VNA Health Group’s In-Home Education and Support for Nonpaid Caregivers provides education on dementia behaviors, medication management, home safety, and community resources.

Paying Attention Is an Act of Care

Noticing memory or behavior changes can be uncomfortable, especially when you are unsure what they mean. But avoiding the conversation does not make the uncertainty easier.

This World Alzheimer’s Month, pay attention to changes that persist, affect daily life, or seem out of character. Write down what you notice and speak with a healthcare professional.

Early detection does not change the person you love. It can simply provide more information, more time, and more opportunities to make thoughtful choices together.
