The First Thing Dementia Takes Isn't Memory

Dementia steals something far more devastating than memories before cognitive decline becomes obvious.

Research published in BMC Geriatrics reveals that anxiety and fear in dementia patients are so prevalent they affect between 38% and 72% of those diagnosed, making these psychological symptoms nearly as universal as the memory problems we typically associate with the disease.

But here’s what changes everything about how we understand this condition.

Anxiety appears to be more common in people with dementia who still have good insight and awareness of their condition.

Translation: the people who understand what’s happening to them suffer the most fear.

A study using the Fear and Avoidance of Memory Loss scale found that after adjusting for objective memory performance and general anxiety, higher fear significantly predicted increased perceived memory failures and reduced quality of life.

The fear itself makes the memory problems worse.

This isn’t just correlation.

When someone with early dementia experiences heightened anxiety about their cognitive changes, they enter a state of hypervigilance that taxes an already compromised brain.

The fear becomes a type of health anxiety, marked by feelings of worry and dread, attentional biases, and ruminative thoughts about perceived risk.

Every forgotten name becomes evidence of decline.

Every misplaced key triggers catastrophic thinking.

The psychological distress creates a vicious cycle where anxiety impairs attention and memory formation, leading to more memory failures, which generates more anxiety.

Think about what this means in practice.

A 67-year-old woman walks into a room and forgets why she’s there.

A normal person shrugs it off.

Someone in early dementia with retained insight panics.

Her heart rate spikes.

Her mind races through worst-case scenarios.

The stress hormones flooding her system make it even harder to remember what she was doing.

The temporary lapse becomes a self-fulfilling prophecy.

The Paradox Nobody Wants to Talk About

Early diagnosis is supposed to be beneficial.

Research suggests newly approved medications work better in the beginning stages of the disease, and an early diagnosis makes individuals eligible for a wider variety of clinical trials.

We’re told that catching dementia early gives patients more time to plan, to try treatments, to maintain autonomy.

But there’s a darker reality we rarely acknowledge.

Patients presenting in the early stages of dementia often need to undergo neuropsychological testing and neuroimaging, processes that can be anxiety-provoking in themselves, as can be the delays involved in waiting for tests and for feedback of test results.

The diagnostic process itself becomes a source of sustained psychological torture.

You sit through cognitive tests designed to expose your deficits.

You undergo brain scans that might show atrophy or plaques.

You wait weeks or months for results, during which every mental slip feels like confirmation.

Then, after all that, you might be told you have “mild cognitive impairment” with its implications of uncertainty and elevated risk.

Not sick enough for treatment.

Too sick to stop worrying.

At the end of the process, a clear diagnosis cannot always be given, with its implications of uncertainty and elevated risk of the subsequent development of dementia.

This is the cruel irony of early awareness.

The very insight that allows someone to seek help also ensures they’ll suffer more intensely from the diagnosis.

The anxiety and agitation are more apparent in the early stages of the disease as people begin to recognize their losses and the seriousness of the disease.

Someone with advanced dementia who has lost insight into their condition may be confused, but they’re not terrified.

Someone in early stages who fully understands they’re losing their mind lives in a state of existential dread.

What Fear Actually Does to Your Brain

The relationship between anxiety and cognitive decline isn’t just psychological.

High levels of anxiety in patients with mild cognitive impairment have an adverse effect on executive functioning, and in early Alzheimer’s disease, anxiety predicts a decline in learning.

This is measurable neurological damage caused by sustained fear.

Chronic anxiety floods the brain with stress hormones.

Cortisol, in particular, has toxic effects on the hippocampus, the brain region responsible for memory formation that’s already compromised in dementia.

When someone lives in constant fear of cognitive decline, they’re essentially bathing their brain in chemicals that accelerate the very decline they’re afraid of.

The fear doesn’t just feel bad.

It makes the disease worse.

In a prospective study of anxiety and cognition in 1,481 men aged between 48 and 67, participants were reassessed after 17 years’ follow-up, and decline in learning and memory was associated with high baseline anxiety score.

The anxiety came first, the cognitive decline followed.

This challenges our basic understanding of dementia as purely a disease of neurodegeneration.

What if some of the cognitive symptoms we attribute to brain pathology are actually manifestations of psychological distress?

Anxiety can make thinking clearly and remembering things even more challenging, particularly affecting a person’s attention, planning, organizing and decision-making.

Attention is the gateway to memory.

If anxiety prevents someone from paying attention in the first place, no memory trace gets formed.

The person appears to have worse dementia than they actually do.

The Behavioral Language of Fear

When someone with dementia can’t articulate their fear, it comes out in behavior.

Persons with dementia may exhibit distressing behaviors in order to communicate their needs, and specific triggers may lead to anxiety-related symptoms such as fatigue, changes in routine, caregiver, or environment, expectation to complete tasks beyond their abilities, feelings of loss, or being unsure of their surroundings.

That “difficult” patient who resists bathing isn’t being stubborn.

They’re terrified because they don’t understand why a stranger is trying to remove their clothes.

That person who follows their spouse everywhere isn’t being clingy.

A person with dementia who is feeling anxious may feel scared to be left on their own and so follow a partner or family member around the home, which can be very difficult to cope with when it happens all the time.

They’re desperately clinging to the one person who still feels safe in a world that’s becoming increasingly incomprehensible.

The agitation we see isn’t a symptom of brain damage.

It’s a rational response to living in a state of constant confusion and fear.

Anxiety can cause changes in behavior, such as becoming agitated or restless, pacing, fidgeting, or repeatedly rubbing, picking or scratching their skin or pulling their hair.

These are self-soothing behaviors.

The same kind of repetitive movements you see in people with severe anxiety disorders.

The body trying to regulate a nervous system that’s in constant overdrive.

When we medicate these behaviors without addressing the underlying fear, we’re treating the symptom while ignoring the cause.

Here’s What Most People Completely Miss

We approach dementia as a memory problem that happens to cause anxiety.

The research suggests it might be closer to the opposite.

Anxiety can commonly occur before the dementia is apparent, and anxiety gradually decreases at the severe stages of dementia.

Think about that trajectory.

Anxiety peaks when awareness is highest.

Anxiety fades as insight disappears.

This means anxiety isn’t just a reaction to having dementia.

It’s tied directly to the person’s understanding of what’s happening to them.

Persons in the early stages of dementia are those most likely to have insight into their abilities and to have higher rates of generalized anxiety disorder and anxiety symptoms.

The better you understand your situation, the more you suffer psychologically.

They are better able to understand their diagnosis, know there is no cure, and experience fears about how the disease will progress.

Imagine being told you have a terminal illness that will strip away your personality, your memories, your ability to recognize your own children.

That you’ll eventually need help eating, bathing, using the toilet.

That you’ll become a burden to everyone you love.

And oh, by the way, there’s no effective treatment.

Now imagine living with that knowledge every single day while watching your cognitive abilities slowly deteriorate.

That’s the psychological reality of early-stage dementia with preserved insight.

The Social Withdrawal Nobody Understands

One of the earliest behavioral changes in dementia is social avoidance.

Higher avoidance was associated with memory failures, poorer verbal memory, reduced social functioning, and quality of life.

People start declining invitations.

They stop participating in activities they used to enjoy.

Family members often interpret this as depression or personality change.

But the mechanism is more specific than that.

Maladaptive behavioral avoidance strategies critically underlie psychosocial dysfunction associated with fear of memory loss.

They’re not avoiding social situations because they don’t want to see people.

They’re avoiding situations where their cognitive deficits might be exposed.

Every social interaction becomes a potential minefield.

Will they forget someone’s name?

Will they lose track of the conversation?

Will they say something inappropriate because they can’t follow social cues?

The anxiety about these possibilities becomes so overwhelming that staying home seems safer.

A person living with Alzheimer’s or other dementia may experience changes in the ability to hold or follow a conversation, and as a result, they may withdraw from hobbies, social activities or other engagements.

But here’s the tragic part.

Emerging evidence suggests that people themselves can reduce their dementia risk by participating in social life.

Social isolation accelerates cognitive decline.

So the fear-driven avoidance that’s meant to protect them actually makes the disease worse.

The very coping mechanism they develop to manage anxiety about their dementia speeds up the progression of their dementia.

The Treatment That Finally Makes Sense

For decades, we’ve treated dementia anxiety with the same playbook we use for general anxiety.

Anti-anxiety medications, antidepressants, reassurance.

These approaches assume anxiety is an irrational overreaction that needs to be suppressed.

A randomized trial evaluating a brief psychological intervention to promote adaptive coping in older adults found that the intervention was effective at reducing fear and avoidance of memory loss, fear of Alzheimer’s disease, self-reported memory failures, anxiety, and depression symptoms.

What made the intervention work?

Both groups received psychoeducation and training in mindful monitoring of fears related to dementia, but the group that received an additional behavioral activation component intended to disrupt maladaptive avoidant coping strategies showed additional positive outcomes on mood and affect.

In other words, acknowledging the fear and teaching people to engage with life despite it, rather than avoiding situations that trigger anxiety.

This represents a fundamental shift in approach.

Instead of trying to convince someone their fear is unfounded (which it isn’t), you validate that living with cognitive decline is genuinely frightening.

Then you give them tools to maintain quality of life despite that fear.

By identifying and effectively treating maladaptive fear early, we may be able to reduce dementia risk, or prevent cases, in later life by fostering healthy lifestyle behaviors such as continued cognitive and social engagement.

Reducing fear doesn’t just make people feel better.

It might slow the disease itself by keeping people engaged in the cognitively and socially stimulating activities that protect brain health.

The Question of When to Tell

Here’s where medicine faces an impossible ethical dilemma.

Studies have shown that anxiety can increase your risk of developing Alzheimer’s disease, and anxiety may also make you delay screening for an early diagnosis that could otherwise help you.

So anxiety both increases disease risk and prevents people from seeking help.

But seeking help and getting diagnosed creates more anxiety.

Which worsens cognitive function.

Which accelerates the disease.

The diagnostic process that’s supposed to help might actually harm people who have preserved insight.

In severe cases, dementia worry can result in a misdiagnosis and the use of unnecessary medications.

Some researchers have started questioning the push for early diagnosis.

If we can’t effectively treat early-stage dementia, and if diagnosis causes severe psychological suffering in people with insight, are we actually helping?

Or are we just giving people years of terror before they would have noticed the symptoms on their own?

Dementia worry is a widespread phenomenon in mid-life and old age, at least in Western populations, reflective of the increasing awareness of dementia in times of increasing dementia encounters, widespread misperceptions of risks and consequences of dementia, and a perceived lack of coping resources.

We’ve created a culture where every forgotten word triggers fear of dementia.

Where normal age-related cognitive changes get pathologized.

Where people live in dread of a disease they may never develop.

Living With Uncertainty

There’s no clean resolution to this problem.

Dementia with preserved insight is inherently terrifying because the person understands exactly what they’re losing.

Individuals living with Alzheimer’s or other dementia may experience mood and personality changes, becoming confused, suspicious, depressed, fearful or anxious, and may be easily upset at home, with friends, or when out of their comfort zone.

But understanding the role of fear changes how we approach care.

If a person with dementia has mild anxiety, it may help to listen to their worries and reassure them, and addressing things that cause anxiety or make it worse can help a person to feel less anxious.

This means environmental modifications matter.

Maintaining routine reduces uncertainty.

Avoiding situations that expose deficits prevents embarrassment and fear.

It also means being honest about what we’re actually treating.

When we give someone anti-anxiety medication for dementia-related fear, we’re not treating irrational anxiety.

We’re chemically suppressing a rational response to a terrifying situation.

Management strategies for anxiety in patients with Alzheimer’s disease involve psychological support, behavioral management, and the judicious use of medications.

Sometimes that’s necessary.

But we should be clear-eyed about what we’re doing and why.

The people suffering most from dementia aren’t necessarily those with the worst cognitive symptoms.

They’re those with enough insight to understand what’s happening but not enough cognitive decline to forget why they’re afraid.

That middle zone where awareness and impairment coexist is where the psychological suffering peaks.

Prolonged fears about memory loss and dementia can have harmful consequences even in the absence of cognitive decline, and fear of dementia is associated with poorer health outcomes and psychological well-being and increased memory failures in older adults.

This is what we mean when we say dementia takes mental safety first.

The secure feeling that your mind is reliable, that you can trust your own cognition, that you’ll recognize the people you love tomorrow.

That disappears long before the memories do.

And for many people, living without that safety is worse than the memory loss itself.
