Supporting Brain Health & Memory
Your brain helps you remember, learn, communicate, make decisions, manage emotions, and complete everyday tasks. Like the rest of your body, it changes as you get older.
Occasionally forgetting a name, misplacing an item, or needing more time to recall information can happen with normal aging. More serious changes—especially those that interfere with familiar activities, safety, or independence—should be discussed with a healthcare professional.
There is no single activity, food, supplement, or puzzle that guarantees you will prevent memory loss or dementia. Brain health is supported by a combination of physical health, mental activity, social connection, sleep, safety, and appropriate medical care.
Support Your Physical Health
The brain depends on oxygen, blood flow, nutrients, and many of the same systems that support the heart and the rest of the body.
Conditions that may affect brain health include:
- High blood pressure
- Diabetes
- High cholesterol
- Heart disease
- Stroke
- Depression
- Hearing loss
- Sleep disorders
- Medication side effects
Follow the treatment plan developed with your healthcare team. Take medications as prescribed, attend appointments, and complete recommended health screenings.
Do not stop a medication because you are worried it may be affecting your memory. Ask the prescriber or pharmacist to review the medication and determine whether an adjustment is appropriate.
The National Institute on Aging recommends caring for physical health as an important part of supporting cognitive health.
Stay Physically Active
Regular physical activity supports circulation, balance, strength, mood, sleep, and overall health. These benefits also support the brain.
Depending on your health and abilities, activity may include:
- Walking
- Swimming
- Chair exercises
- Dancing
- Gardening
- Strength training
- Balance exercises
- Household activities
- Fitness or recreation classes
Choose activities you can perform safely and consistently. If you have been inactive, have a medical condition, or are concerned about falling, ask a healthcare professional how to begin.
You do not need to complete an intense workout for movement to matter. Short periods of activity throughout the day can still be useful.
Eat in a Way That Supports Overall Health
No single food has been proven to prevent dementia. A balanced eating pattern can support your heart, blood vessels, energy, and general health.
Try to include:
- Vegetables
- Fruits
- Whole grains
- Beans and other sources of fiber
- Fish and lean sources of protein
- Nuts and seeds when safe for you
- Healthy fats
- Adequate water
Limit foods and drinks that are high in added sugar, sodium, or heavily processed fats.
If chewing, swallowing, cooking, shopping, or affording nutritious food has become difficult, explain the specific problem to your healthcare team. A dentist, dietitian, occupational therapist, speech-language pathologist, caregiver, or community program may be able to help.
Be cautious of supplements advertised as memory boosters. “Natural” does not mean safe or effective. Supplements may interact with medications or medical conditions. Ask a healthcare professional before taking them.
Get Consistent Sleep
Sleep supports attention, learning, memory, mood, and physical recovery. Poor sleep can make it harder to think clearly during the day.
Helpful habits include:
- Going to bed and waking up at consistent times
- Creating a calming bedtime routine
- Keeping the bedroom dark, quiet, and comfortable
- Limiting caffeine later in the day
- Reducing alcohol
- Avoiding long or late naps
- Staying active during the day
- Limiting bright screens near bedtime
Talk with a healthcare professional if you regularly:
- Have difficulty falling or staying asleep
- Snore loudly
- Gasp or stop breathing during sleep
- Wake with headaches
- Feel extremely sleepy during the day
- Act out dreams
- Experience confusion after waking
Sleep apnea and other sleep disorders can affect health, attention, and memory. They should not be dismissed as ordinary aging.
Keep Learning & Using Your Mind
Activities that require attention, planning, creativity, or learning can help keep your mind engaged.
You might:
- Read
- Write
- Complete puzzles
- Learn a language
- Play an instrument
- Take a class
- Cook a new recipe
- Practice a craft
- Play cards or strategy games
- Learn to use new technology
- Volunteer
- Visit museums or community programs
Choose activities that are interesting and appropriately challenging. The goal is not to frustrate yourself or achieve a perfect score. It is to remain curious, practice skills, and continue learning.
Be cautious of programs claiming that one game or exercise can prevent dementia. Brain-training activities may help you practice specific skills, but they are not a guaranteed form of prevention.
Stay Socially Connected
Regular interaction with other people can support mood, communication, thinking, and a sense of purpose.
Connection may include:
- Calling a friend
- Eating with family
- Attending a community program
- Joining a club or faith community
- Taking a class
- Volunteering
- Visiting a senior or recreation center
- Participating in an online group
- Spending time with neighbors
- Helping with a shared project
Social connection does not require a large circle of friends. A few consistent, meaningful relationships can matter.
If hearing or vision problems make social activities difficult, address those barriers. Hearing aids, glasses, captions, better lighting, quieter environments, or accessible transportation may make participation easier.
Protect Your Hearing & Vision
Hearing and vision help the brain receive and organize information. Difficulty seeing or hearing can make conversations, reading, navigation, and social participation more demanding.
Schedule appropriate eye and hearing examinations. Use prescribed glasses, hearing aids, and accessibility features.
The CDC includes treating hearing loss among the steps that may help reduce dementia risk.
If you often misunderstand conversations or cannot clearly see written information, it may look like a memory problem when the information was never fully received in the first place.
Protect Your Head
A head injury can affect memory, thinking, balance, and behavior.
Reduce your risk by:
- Wearing a seat belt
- Using an appropriate helmet
- Removing tripping hazards
- Improving lighting
- Installing handrails and grab bars
- Wearing supportive footwear
- Using mobility equipment as recommended
- Reviewing medications that may cause dizziness
- Addressing vision and balance changes
- Avoiding driving when impaired
Seek medical attention after a significant head injury, especially if you experience confusion, vomiting, severe headache, unusual sleepiness, weakness, loss of consciousness, or changes in speech or vision.
Call 911 for severe symptoms or an immediate emergency.
Limit Tobacco & Alcohol
Smoking affects the heart and blood vessels and increases the risk of stroke and other health problems associated with cognitive decline.
If you smoke, ask about support for quitting. Even after many years, stopping can benefit your health.
Alcohol can affect judgment, coordination, sleep, medication safety, and memory. Older adults may become more sensitive to alcohol because of changes in metabolism, medical conditions, and medication use.
Avoid combining alcohol with medications unless a healthcare professional confirms that it is safe. If drinking has become difficult to control, talk with a healthcare professional honestly. Help is available.
Support Your Mental Health
Depression, anxiety, grief, stress, and loneliness can affect concentration, motivation, sleep, and memory.
Possible signs include:
- Loss of interest in usual activities
- Persistent sadness or worry
- Low energy
- Difficulty concentrating
- Changes in appetite or sleep
- Irritability
- Feeling hopeless
- Withdrawing from other people
These symptoms deserve care. They are not weaknesses or unavoidable parts of aging.
Contact a healthcare or mental health professional if emotional changes continue or interfere with daily life. Call or text 988 in the United States if you are experiencing a mental health crisis or thoughts of suicide. Call 911 for immediate danger.
Review Your Medications
Some medications and medication combinations can contribute to confusion, sleepiness, dizziness, or memory difficulty.
Bring a complete list to appointments, including:
- Prescription medications
- Over-the-counter medicines
- Sleep aids
- Allergy products
- Vitamins
- Herbal products
- Supplements
Ask:
- Could any of these affect memory or alertness?
- Are any products doing the same job?
- Is the dose still appropriate?
- Could timing affect sleep or daytime alertness?
- Are any combinations unsafe?
- Can the medication schedule be simplified?
Use one pharmacy when possible so the pharmacist can review potential interactions.
Never stop a prescribed medication suddenly unless a qualified professional instructs you to do so.
Use Memory Supports
Using a calendar, reminder, or written list does not weaken your memory. These tools reduce the amount of information you need to hold in your mind and make important tasks more dependable.
Helpful supports include:
- A calendar
- A daily planner
- A written routine
- Phone reminders
- Medication alarms
- A pill organizer
- Labels
- A designated location for keys and glasses
- Written appointment information
- Automatic bill payments
- A shopping list
- A notebook for questions and instructions
Keep systems simple. Using one calendar consistently is often more effective than keeping information in several places.
Place frequently used items in the same location. Complete one task at a time when possible, especially when the task involves medication, money, cooking, or safety.

Understand Normal Forgetfulness
Occasional forgetfulness can happen at any age.
Examples may include:
- Temporarily forgetting a name but remembering it later
- Misplacing an item occasionally
- Needing a reminder for an appointment
- Taking longer to learn unfamiliar technology
- Walking into a room and briefly forgetting why
- Making an occasional mistake
Normal aging may slow how quickly you recall information. It should not prevent you from managing familiar daily activities.
Recognize Changes That Should Be Evaluated
Contact a healthcare professional if memory or thinking changes begin interfering with everyday life.
Examples include:
- Getting lost in familiar places
- Missing important appointments repeatedly
- Forgetting recently learned information frequently
- Asking the same question repeatedly
- Having difficulty following familiar instructions
- Struggling to manage medications
- Making unusual financial mistakes
- Leaving appliances on
- Becoming confused about time or location
- Having difficulty finding common words
- Showing significant changes in judgment
- Withdrawing because familiar activities have become confusing
- Having personality or behavior changes
- Needing increasing help with tasks you previously handled independently
Not every memory problem is dementia. Possible causes can include medication effects, depression, infection, sleep problems, thyroid conditions, vitamin deficiencies, hearing loss, stroke, alcohol use, and other medical conditions.
An evaluation can help identify what is happening and whether treatment or additional support is needed.
Know When Confusion Is an Emergency
Sudden confusion is not the same as gradually increasing forgetfulness.
Call 911 or seek emergency medical attention if someone suddenly:
- Becomes confused or disoriented
- Cannot speak clearly
- Has facial drooping or weakness
- Develops a severe headache
- Has difficulty walking
- Loses consciousness
- Experiences a seizure
- Has confusion after a fall or head injury
- Cannot be awakened normally
Sudden confusion may be related to stroke, infection, medication problems, low blood sugar, dehydration, head injury, or another urgent condition.
Do not leave a suddenly confused person alone or allow them to drive.
Prepare for a Memory Appointment
Before the appointment, write down:
- What changes you noticed
- When they began
- How often they occur
- Whether they are becoming worse
- How they affect daily activities
- Recent illnesses or injuries
- Changes in mood or sleep
- Alcohol use
- Current medications and supplements
- Family history
Bring someone who knows you well if you are comfortable doing so. That person may remember examples or help you understand the instructions.
Ask:
- Could a medication or medical condition be causing this?
- What testing is recommended?
- Are hearing, vision, sleep, or mood contributing?
- What changes should be monitored?
- What can I do to remain safe and independent?
- When should I return?
- What symptoms require urgent care?
Final Thoughts
Supporting brain health is not about completing one perfect puzzle, eating one special food, or buying a supplement that promises to protect your memory.
The strongest approach is broader: care for your physical health, stay active, sleep consistently, keep learning, maintain social connections, protect your hearing and vision, and address medical or emotional concerns.
Use calendars, reminders, lists, labels, and routines whenever they make life easier. Memory supports are tools for independence.
Occasional forgetfulness can be part of normal aging. Changes that interfere with familiar tasks, safety, judgment, or independence deserve a professional evaluation. Sudden confusion, stroke symptoms, or major changes after a head injury require immediate medical attention.
