Early Warning Signs of Cognitive and Hearing Changes

Early Warning Signs of Cognitive and Hearing Changes

Early hearing changes may include difficulty understanding conversations, frequently asking people to repeat themselves, or turning up the television volume. Early cognitive changes may involve increasing forgetfulness, difficulty completing familiar tasks, problems finding words, or changes in judgment.

Some symptoms overlap. Someone who misses spoken information because of hearing loss may appear forgetful or inattentive. However, hearing difficulties and cognitive impairment can also occur together.

Not every change indicates dementia or a serious hearing disorder. The important questions are whether symptoms are new, persistent, worsening, or interfering with everyday life.

Recognizing changes early can help people obtain appropriate hearing or medical evaluations rather than guessing at the cause.

Hearing Changes vs Cognitive Changes: What to Watch For

Possible Hearing Changes	Possible Cognitive Changes
Frequently asking people to repeat themselves.	Frequently forgetting information that was clearly understood.
Difficulty understanding speech in noisy places.	Difficulty completing familiar tasks or following familiar procedures.
Turning the television louder than others prefer.	Increasing difficulty managing appointments, medications, or finances.
Hearing speech but missing particular words.	Increasing difficulty finding words or organizing thoughts.
Difficulty understanding telephone conversations.	Becoming lost or confused in familiar places.
Withdrawing from conversations because hearing is difficult.	Changes in judgment, planning, or everyday behavior.

These examples are not diagnostic criteria. Hearing loss, cognitive conditions, stress, sleep problems, and other health issues may produce overlapping symptoms.

Early Warning Signs of Hearing Loss

Hearing changes often develop gradually, making them difficult to recognize at first.

According to the National Institute on Deafness and Other Communication Disorders (NIDCD), common warning signs include difficulty understanding conversations, problems hearing in group settings, and increased television or radio volume.

1. Frequently Asking People to Repeat Themselves

Someone with hearing loss may hear that another person is speaking without understanding every word.

They may respond with “What?” or ask the speaker to repeat a sentence, especially when the speaker is facing away.

These difficulties can occur with mild hearing loss, sometimes before the person recognizes a hearing problem.

2. Difficulty Understanding Speech in Background Noise

Restaurants, family gatherings, busy workplaces, and group conversations can reveal hearing difficulties that are less noticeable in quiet environments.

A person may understand one speaker in a quiet room but struggle when multiple voices or other sounds compete.

Difficulty hearing in noise does not automatically indicate a particular type or degree of hearing loss. An audiologist can help determine what is contributing.

3. Increasing Television or Phone Volume

Regularly increasing the volume beyond what others find comfortable may indicate reduced hearing sensitivity.

However, volume preferences alone cannot diagnose hearing loss. Background noise, television audio quality, and individual listening preferences also matter.

4. Feeling Exhausted After Conversations

Hearing difficulties can increase the effort required to follow speech.

Some people become tired or frustrated after meetings, group conversations, or other demanding listening situations.

People with severe hearing loss may experience substantial communication challenges and need additional accommodations.

Listening fatigue does not necessarily indicate cognitive decline.

5. Noticing Tinnitus or Changes in Sound Clarity

Tinnitus, commonly described as ringing, buzzing, or other sounds without an external source, sometimes occurs alongside hearing loss.

Some people also notice that speech sounds muffled or that certain voices are harder to understand.

Tinnitus does not always mean hearing loss is present, but persistent or bothersome symptoms may warrant hearing evaluation.

Because changes can occur gradually, learn more about why hearing loss develops so gradually.

Early Warning Signs of Cognitive Changes

Cognitive functioning includes memory, attention, language, reasoning, planning, and other mental abilities.

Some changes in processing speed or memory retrieval can occur with normal aging.

However, persistent or worsening changes that interfere with daily responsibilities deserve medical assessment.

1. Increasing Forgetfulness

Occasionally misplacing keys or forgetting a name is common.

More concerning patterns may include:

• Frequently forgetting recent conversations or important events.
• Repeatedly asking the same question.
• Missing appointments despite previously reliable routines.
• Having difficulty remembering important instructions.

The frequency, progression, and effect on everyday life matter more than one isolated memory lapse.

2. Difficulty Completing Familiar Tasks

Someone may begin having trouble following a familiar recipe, organizing bills, managing medications, or completing activities previously handled independently.

These difficulties can reflect several possible conditions, including cognitive impairment, depression, medication effects, or other medical problems.

A professional evaluation can help clarify the cause.

3. Problems With Language or Finding Words

Occasionally struggling to remember a word can happen at any age.

More persistent difficulties may involve frequently losing the thread of a conversation, having trouble naming familiar objects, or struggling to communicate ideas that were previously easy to express.

Hearing loss may also interfere with understanding a conversation, so clinicians need to consider both listening and language abilities.

4. Changes in Planning, Judgment, or Decision-Making

Some cognitive changes affect executive functions, including planning, organizing, attention, and decision-making.

Possible signs include increasing difficulty managing several responsibilities, following a familiar sequence of steps, or making appropriate everyday decisions.

These symptoms are not specific to dementia and may also occur with poor sleep, stress, depression, or medical conditions.

5. Getting Lost or Confused in Familiar Places

Increasing difficulty navigating familiar environments or becoming confused about familiar places is more concerning than occasionally forgetting why you entered a room.

Changes in orientation or everyday functioning deserve medical evaluation.

Can Hearing Loss Look Like Cognitive Decline?

Yes. Hearing loss can sometimes make someone appear forgetful, distracted, or confused during conversations.

Consider a person who misses several words in a spoken instruction.

When they later fail to complete the instruction correctly, the problem may involve not hearing the information accurately rather than forgetting something they fully understood.

However, this distinction is not always obvious.

Some people have both hearing loss and cognitive impairment, and one condition should not automatically be used to explain away symptoms of the other.

Hearing status is especially important during cognitive screening because some cognitive tests rely on spoken questions or instructions.

For more information, see our article on cognitive screening and hearing loss.

Does Hearing Loss Cause Dementia?

Research has consistently identified an association between hearing loss and greater risk of cognitive decline or dementia in older adults.

However, an association does not prove that hearing loss directly causes dementia in every person.

Researchers are investigating several possible explanations, including increased listening effort, reduced social participation, shared health risks, and changes in auditory and cognitive functioning.

These mechanisms may interact, and the relationship is not fully understood.

Importantly, hearing loss is not a diagnostic warning sign that someone has Alzheimer’s disease.

Many people with hearing loss do not develop dementia, and dementia can occur in people without hearing loss.

Can Hearing Aids Reduce Cognitive Decline?

Hearing aids can improve access to speech and support communication for appropriately selected individuals.

The ACHIEVE randomized clinical trial investigated hearing intervention and cognitive decline among older adults with untreated hearing loss.

Over three years, the trial found no statistically significant overall difference in cognitive decline between the hearing intervention and control groups.

However, a prespecified analysis suggested a possible benefit among participants at greater risk for cognitive decline.

These findings support continued research but do not establish that hearing aids universally prevent dementia.

Hearing rehabilitation remains valuable for communication and hearing-related quality of life regardless of uncertain dementia-prevention effects.

Read the ACHIEVE randomized trial.

Can Sleep Problems Cause Hearing or Cognitive Symptoms?

Insufficient or disrupted sleep can affect attention, memory, alertness, and mental stamina.

Someone experiencing poor sleep may appear forgetful or struggle to follow conversations because concentration has become more difficult.

Obstructive sleep apnea is a condition involving repeated breathing interruptions during sleep.

Possible warning signs include:

• Loud habitual snoring.
• Witnessed pauses in breathing.
• Gasping or choking during sleep.
• Persistent daytime sleepiness.
• Waking without feeling rested.

Sleep apnea has been associated with cognitive difficulties and certain longer-term health risks, but these symptoms do not establish that dementia is developing.

People with suspected sleep apnea should discuss evaluation with a healthcare professional.

Other Conditions That Can Affect Thinking and Memory

Not every cognitive change results from a neurodegenerative disorder.

Possible contributors include:

• Depression or anxiety.
• Thyroid disorders.
• Vitamin B12 deficiency.
• Medication side effects.
• Diabetes and other metabolic conditions.
• Sleep disorders.
• Stroke or traumatic brain injury.
• Other neurological or medical illnesses.

Some contributing conditions are treatable, although improvement is not guaranteed and depends on the underlying cause.

New or worsening cognitive symptoms should be evaluated rather than automatically attributed to aging, hearing loss, or stress.

When Should You Get Your Hearing Checked?

Consider a hearing evaluation when you notice persistent difficulty understanding speech, increased need for repetition, tinnitus, or other changes in hearing.

A comprehensive evaluation may include:

• Pure-tone audiometry to measure hearing sensitivity.
• Speech testing to assess aspects of speech understanding.
• Tympanometry to evaluate middle-ear function.
• Additional tests when indicated by symptoms and clinical findings.

For example, a word recognition test measures how accurately a person recognizes spoken words under specific testing conditions.

Acoustic reflex testing evaluates an involuntary middle-ear muscle response to sound and may provide additional information about auditory pathways.

Neither test diagnoses dementia or independently determines cognitive ability.

Not everyone requires every audiological procedure. An audiologist selects tests according to the reason for evaluation.

When Should You Seek a Cognitive Evaluation?

Speak with a healthcare professional if memory, language, judgment, or thinking changes:

• Persist or progressively worsen.
• Interfere with everyday responsibilities.
• Are noticed by family members or caregivers.
• Affect safety, medication management, or finances.
• Occur alongside other concerning medical or neurological symptoms.

A primary care clinician may review symptoms, medications, sleep, mood, hearing status, and medical history.

Depending on the findings, additional cognitive testing, laboratory work, hearing assessment, or specialist referral may be appropriate.

A screening test can identify possible impairment, but it does not independently diagnose dementia.

Which Hearing and Cognitive Changes Need Urgent Attention?

Some symptoms require prompt action rather than a routine appointment.

Sudden Hearing Loss

Sudden hearing loss, particularly in one ear, requires urgent medical evaluation because sudden sensorineural hearing loss may need time-sensitive treatment.

Do not assume that suddenly muffled hearing is simply earwax or congestion.

Sudden Confusion or Neurological Symptoms

Call 911 immediately for sudden confusion, difficulty speaking, facial drooping, weakness on one side, sudden vision changes, loss of coordination, or a severe unusual headache.

These symptoms may indicate stroke or another medical emergency.

Even when symptoms improve quickly, urgent evaluation may still be necessary.

See the CDC’s stroke warning signs.

Practical Steps to Support Hearing and Brain Health

Although no single action guarantees prevention of cognitive decline, several practical steps can support overall health and communication.

• Address hearing difficulties: Seek assessment when hearing changes affect conversations or daily activities.
• Protect hearing: Reduce exposure to hazardous noise and use appropriate hearing protection.
• Support sleep: Maintain appropriate sleep habits and seek care for persistent sleep problems.
• Manage cardiovascular and metabolic health: Work with your clinician to address conditions such as hypertension and diabetes.
• Stay physically active: Choose activities suitable for your health and abilities.
• Maintain social connections: Seek communication accommodations when hearing problems make participation difficult.
• Review medications: Discuss possible cognitive side effects with a clinician or pharmacist.
• Pay attention to changes: Keep a record of new or worsening hearing, memory, or communication symptoms.

These measures can support general well-being, but they should not be presented as guaranteed dementia-prevention treatments.

Frequently Asked Questions

What Are the First Signs of Hearing Loss?

Early signs may include asking people to repeat themselves, difficulty understanding speech in background noise, increased television volume, and trouble following conversations.

What Are the First Signs of Cognitive Decline?

Possible warning signs include increasing forgetfulness, difficulty completing familiar tasks, changes in language or judgment, and problems managing everyday responsibilities. These symptoms require evaluation rather than self-diagnosis.

Can Hearing Loss Make Someone Seem Forgetful?

Yes. Missing spoken information may make someone appear to have forgotten instructions or conversations. However, hearing loss and genuine cognitive impairment can coexist.

Does Hearing Loss Mean Someone Is Developing Alzheimer’s Disease?

No. Hearing loss is associated with dementia risk in research, but it is not a diagnosis or reliable individual predictor of Alzheimer’s disease.

Can Hearing Aids Prevent Dementia?

Hearing aids can improve access to sound and communication. Research into cognitive outcomes continues, but hearing aids cannot be guaranteed to prevent dementia.

Can Poor Sleep Cause Memory Problems?

Yes. Insufficient or disrupted sleep can affect attention, memory, and thinking. Persistent symptoms may require assessment for sleep disorders or other medical conditions.

Should I Get a Hearing Test or a Memory Test First?

The appropriate first step depends on your symptoms. An audiologist can assess hearing difficulties, while a primary care clinician can evaluate memory or thinking changes. When both are present, coordinated evaluation may be appropriate.

Is It Normal for Hearing and Memory to Change With Age?

Some hearing and cognitive abilities change with age, but significant hearing loss or cognitive impairment should not be dismissed as inevitable. Symptoms affecting everyday functioning deserve appropriate evaluation.

The Bottom Line

Early hearing changes often involve difficulty understanding speech, asking for repetition, or struggling in noisy environments.

Early cognitive changes may involve worsening memory, difficulty completing familiar tasks, language problems, or changes in everyday judgment.

Because symptoms can overlap, hearing loss should not automatically be mistaken for cognitive decline, and cognitive problems should not be dismissed as hearing difficulties.

Timely hearing and medical evaluations can help identify possible causes, clarify appropriate care, and support everyday functioning.
