How to Improve Memory After 70: Science-Backed Tips

If you have noticed your memory is not quite what it used to be, you are not alone — and you are not powerless. While some memory changes are a normal part of aging, research consistently shows that the right habits can slow decline, strengthen recall, and even improve memory performance well into your 70s, 80s, and beyond.

Here are science-backed strategies that actually work.

1. Exercise Your Brain Regularly

The "use it or lose it" principle applies strongly to memory. A landmark study published in the New England Journal of Medicine followed older adults for over 20 years and found that those who regularly engaged in mentally stimulating activities had a significantly lower risk of cognitive decline.

The key is variety and consistency. Different types of brain exercises target different cognitive skills:

• Memory games like card matching and sequence recall directly train your ability to store and retrieve information. Try our Memory Card Match or Sequence Memory games.
• Word games strengthen language processing and vocabulary recall — skills that support clear thinking and communication. Explore our Word Games collection.
• Trivia and knowledge games exercise long-term memory retrieval, pulling facts from deep storage. Browse our Nostalgia Trivia quizzes.
• Logic puzzles like Sudoku build reasoning skills that support memory organization.

Aim for 15 to 20 minutes of brain exercise daily. Our Daily Challenge is a great way to start — five questions across different categories in just a few minutes.

2. Get Quality Sleep

Sleep is when your brain consolidates memories — transferring information from short-term to long-term storage. Poor sleep is one of the most common and overlooked causes of memory problems in older adults.

Research from the University of California, Berkeley found that the quality of deep sleep in older adults directly predicted their ability to remember new information the next day.

To improve sleep quality:

• Keep a consistent sleep schedule, even on weekends
• Avoid screens for at least 30 minutes before bed — try a printable puzzle instead
• Keep your bedroom cool, dark, and quiet
• Limit caffeine after noon
• Talk to your doctor if you regularly wake up feeling unrefreshed

3. Stay Physically Active

Exercise is one of the most powerful memory boosters available, and it works at any age. A 2020 meta-analysis in the British Journal of Sports Medicine found that regular physical activity improved memory and thinking skills in older adults, with the benefits increasing with exercise duration.

You do not need to run marathons. Walking for 30 minutes most days, gardening, swimming, or gentle yoga all count. The important thing is consistency. Physical activity increases blood flow to the brain and promotes the growth of new brain cells in the hippocampus — the brain region most critical for memory.

4. Eat a Brain-Healthy Diet

What you eat affects how well your brain works. The MIND diet — a combination of the Mediterranean and DASH diets — was specifically designed to protect brain health and has been shown to reduce the risk of cognitive decline by up to 53 percent in people who follow it closely.

Brain-friendly foods include:

• Leafy green vegetables (at least six servings per week)
• Berries, especially blueberries and strawberries
• Nuts, particularly walnuts
• Fatty fish like salmon and sardines
• Whole grains and olive oil

Foods to limit include red meat, butter, cheese, pastries, and fried foods. Even small dietary changes can add up over time.

5. Stay Socially Connected

Loneliness and social isolation are significant risk factors for memory decline. A study in the Journal of Neurology, Neurosurgery and Psychiatry found that socially active people had a 26 percent lower risk of developing dementia.

Social interaction exercises memory in real time — remembering names, following conversations, and recalling shared experiences all require active cognitive engagement. Make an effort to:

• Talk to friends or family regularly
• Join a club, class, or community group
• Play games with others — trivia and word games are naturally social
• Volunteer in your community

6. Use Memory Strategies

Simple techniques can dramatically improve your day-to-day memory:

• Repetition: When you learn something new, repeat it several times. Say a person's name back to them: "Nice to meet you, Margaret."
• Association: Link new information to something you already know. If you meet someone named Rose, picture them holding a rose.
• Chunking: Break long numbers or lists into smaller groups. Remember a phone number as three chunks instead of ten individual digits.
• Routine: Always put your keys, glasses, and wallet in the same place. Routine eliminates the need to remember.
• Writing it down: The act of writing helps encode information in memory, even if you never look at the note again.

7. Manage Stress and Stay Positive

Chronic stress floods the brain with cortisol, which can impair memory formation and retrieval. Finding ways to manage stress — whether through meditation, deep breathing, hobbies, or simply spending time in nature — directly supports memory function.

Your attitude matters too. Research shows that older adults who believe memory decline is inevitable perform worse on memory tests than those who believe they can maintain and improve their abilities. Stay positive about your brain's capacity to grow.

8. Review Your Medications

Some common medications can affect memory, including certain sleep aids, antihistamines, blood pressure medications, and anxiety drugs. If you have noticed memory changes that coincide with starting a new medication, talk to your doctor. Often there are alternative medications with fewer cognitive side effects.

Small Steps, Big Results

You do not need to overhaul your entire life to improve your memory. Start with one or two changes — perhaps a daily brain game and a 20-minute walk — and build from there. The brain remains remarkably adaptable at any age. Every memory game you play, every good night of sleep, and every conversation you have contributes to keeping your mind sharp.
