⚡ Responding to Memory & Thinking Changes

Changes in memory, judgment, attention, communication, or problem-solving can have many causes. Some develop gradually, while others appear suddenly.

Do not assume that every memory problem is dementia or a normal part of aging. Sudden confusion can be a medical emergency. Gradual changes should also be discussed with a healthcare provider when they begin interfering with everyday life.

Start Here

Ask:

• Did the change begin suddenly or gradually?
• What is different from the person’s usual behavior?
• Is the person safe right now?
• Can they identify themselves and where they are?
• Are they having difficulty speaking or moving?
• Have they fallen or hit their head?
• Have medications recently changed?
• Are they eating and drinking?
• Could they be sick, in pain, or sleep-deprived?
• Can they safely manage medications, cooking, driving, and finances?

Write down what you observe and when it began.

Call 911 If the Person:

• Becomes suddenly confused for no known reason
• Has sudden difficulty speaking or understanding speech
• Has weakness or numbness, especially on one side
• Has sudden difficulty seeing, walking, or maintaining balance
• Has a sudden severe headache
• Is unconscious or cannot be awakened
• Has a seizure
• Has severe chest pain or difficulty breathing
• Became confused after a fall or head injury
• May have taken too much medication
• May have taken the wrong medication
• May hurt themselves or someone else

Sudden confusion can be caused by a serious and potentially treatable medical problem. It should not automatically be assumed to be dementia.

1. Stay Calm and Reduce Stimulation

If the person is confused:

• Approach slowly
• Identify yourself
• Speak calmly
• Use short sentences
• Ask one question at a time
• Reduce noise
• Turn off unnecessary televisions or radios
• Move other people away if the room is crowded
• Provide good lighting
• Give the person time to respond

Avoid surrounding, grabbing, rushing, or arguing with the person.

Your calm behavior may help them feel safer.

2. Check Immediate Needs

Confusion or changes in behavior may become worse when the person is:

• Hungry
• Thirsty
• Tired
• In pain
• Too hot or cold
• Frightened
• Overstimulated
• Constipated
• Needing the bathroom
• Unable to hear or see clearly
• Experiencing medication effects

Check whether the person has their:

• Eyeglasses
• Hearing aids
• Mobility equipment
• Communication device
• Familiar personal items

Do not give additional medication to calm the person unless it has been specifically prescribed for that situation and you understand the instructions.

3. Do Not Test or Challenge the Person

Avoid repeatedly asking questions such as:

• “Don’t you remember?”
• “What day is it?”
• “Who am I?”
• “Why would you do that?”
• “How could you forget?”

These questions may increase embarrassment, fear, or frustration.

Instead, provide the information naturally:

“Hi, it’s Scott. I’m here to help you.”

“It’s Monday morning, and we’re at home.”

“Your appointment is after lunch. We have plenty of time.”

The goal is to support the person, not prove that they are confused.

4. Look for Patterns

Record specific examples of what is changing.

Possible signs include:

• Asking the same questions repeatedly
• Forgetting recent conversations
• Missing appointments
• Getting lost in familiar places
• Losing track of the date or season
• Difficulty following directions
• Difficulty completing familiar tasks
• Trouble managing money
• Missing or repeating medications
• Leaving appliances running
• Misplacing items frequently
• Difficulty following a conversation
• Using unusual or incorrect words
• Making decisions that are very different from usual
• Becoming unusually fearful or suspicious
• Neglecting food, hygiene, or household responsibilities

The National Institute on Aging recommends talking with a healthcare provider when memory changes interfere with familiar activities, personal care, navigation, finances, or everyday safety.

5. Record When the Changes Happen

Write down:

• Date and time
• What happened
• What the person said or did
• What was happening beforehand
• How long it lasted
• What helped
• Whether it has happened before
• Any related physical symptoms
• Recent medication changes
• Changes in sleep, food, or fluid intake

Patterns may show that changes happen:

• At a certain time of day
• After taking medication
• When the person is tired
• In noisy environments
• Before meals
• When routines change
• During illness or pain
• In unfamiliar places

Bring these notes to the healthcare appointment.

6. Review Medications

Gather:

• Prescription medications
• Over-the-counter medicines
• Vitamins
• Supplements
• Sleep aids
• Allergy medicines
• Pain medications

Check for:

• New medications
• Changed dosages
• Missed doses
• Duplicate doses
• Expired medications
• Medications prescribed by different providers
• Difficulty following the schedule
• Increased sleepiness, dizziness, or confusion

Contact the pharmacist or healthcare provider if medication problems may be contributing.

Do not stop or change medication without appropriate professional guidance.

7. Arrange a Medical Evaluation

Schedule an appointment when changes are gradual, repeated, or interfering with everyday life.

Bring:

• A list of specific changes
• When each change began
• Current medication list
• Medical history
• Information about recent illnesses
• Details about falls or injuries
• Changes in sleep, appetite, mood, or behavior
• Questions from the person and caregiver

Possible causes may include medication effects, infection, dehydration, pain, sleep problems, depression, vision or hearing loss, nutritional problems, or neurological conditions.

Only an appropriate healthcare professional can evaluate the cause.

8. Make Everyday Tasks Easier

Helpful supports may include:

• A large clock
• An easy-to-read calendar
• A written daily schedule
• Labels on drawers and doors
• Medication reminders
• Automatic bill payments
• A designated place for important items
• Step-by-step written directions
• Prepared meals
• A shared calendar
• Daily check-in calls
• Consistent routines

Introduce one change at a time.

Too many new systems may create additional confusion.

9. Protect Important Daily Activities

Check whether the person can safely manage:

• Medications
• Cooking
• Driving
• Shopping
• Bills
• Banking
• Appointments
• Personal hygiene
• Household appliances
• Doors and locks
• Emergency communication

Provide support where the risk is greatest.

Do not automatically take control of everything. The person may still be able to manage many activities with reminders, supervision, or small changes.

10. Review Home Safety

Look for risks involving:

• Stove or oven use
• Medications
• Cleaning products
• Tools and weapons
• Stairs
• Loose rugs
• Poor lighting
• Exterior doors
• Car keys
• Smoke and carbon monoxide alarms
• Emergency exits

If the person may wander:

• Keep a recent photograph
• Make sure identification is available
• Tell trusted neighbors
• Consider door alerts
• Secure dangerous areas
• Create a plan for searching and calling for help

Any safety system must still allow people to leave during a fire or other emergency.

11. Communicate Without Arguing

When the person says something inaccurate or becomes confused, decide whether correcting them is necessary for safety.

Try:

• Acknowledging the emotion
• Offering reassurance
• Redirecting attention
• Providing a simple choice
• Moving to a quieter space
• Returning to the topic later

For example:

Instead of:

“You’re wrong. Your mother died years ago.”

Try:

“You miss your mother. Tell me about her.”

You do not need to confirm something untrue, but repeated confrontation may increase distress without solving the problem.

12. Respond Safely to Agitation

If the person becomes angry or agitated:

• Stay at a safe distance
• Keep your voice calm
• Do not block the exit
• Remove other people from the area
• Reduce noise
• Avoid touching the person without warning
• Look for pain, fear, or another unmet need
• Give them time and space
• Remove dangerous objects when it is safe

Leave the area and call for emergency help if anyone is in danger.

Tell emergency responders that the person is experiencing memory or thinking changes so they can adjust their approach.

13. Involve the Person in Decisions

Memory changes do not automatically mean someone can no longer make decisions.

Continue to:

• Speak directly to the person
• Ask what they want
• Offer manageable choices
• Explain changes
• Preserve familiar routines
• Respect privacy
• Support remaining abilities
• Include them in appointments and planning

Legal decision-making ability depends on the particular decision and the person’s ability to understand it. Seek appropriate medical and legal guidance when decision-making authority is unclear.
