How can older adults improve the difficulty they have with multitasking?

Research from the University of California, San Francisco, has pinpointed that older adults have more difficulty switching between tasks due to a 'switching glitch' in the brain, affecting working memory. This does not mean the ability is lost, but that the process requires different strategies. Here is how older adults can improve the difficulty they have with multitasking and stay mentally sharp.

Quick Summary

This guide provides practical strategies for older adults to improve multitasking by focusing on single-tasking, reducing distractions, and incorporating lifestyle habits that support brain health. It offers actionable advice on time management, cognitive training, and dual-task exercises to enhance attention and focus.

Key Points

• Embrace Single-Tasking: Focusing on one task at a time is more efficient and less stressful than juggling multiple tasks, which can be draining for the aging brain.

• Control Your Environment: Reduce distractions by creating a tidy workspace, turning off notifications, and minimizing ambient noise to improve focus.

• Engage in Dual-Task Training: Practice performing a cognitive and a motor task simultaneously to enhance task-switching abilities, as shown in studies with cognitive video games.

• Prioritize Quality Sleep: Adequate, consistent sleep is vital for memory consolidation and maintaining strong cognitive function throughout the day.

• Stay Physically Active: Regular aerobic exercise boosts blood flow to the brain, directly supporting focus and concentration.

• Learn New Skills: Challenging your brain with new hobbies or languages fosters cognitive flexibility and builds new neural connections.

• Practice Mindfulness: Techniques like meditation can help calm the mind, manage stress, and improve the ability to remain focused on the present task.

• Prioritize with Lists and Time Blocks: Use daily to-do lists and time-blocking techniques to organize tasks and manage your time effectively without relying solely on memory.

For older adults seeking to improve their cognitive function, particularly when it comes to juggling multiple tasks, the key lies in understanding the brain's natural aging process and adapting strategies to work with, rather than against, it. Multitasking, contrary to its reputation for efficiency, is often less about doing several things at once and more about quickly switching between tasks, a process that becomes less efficient with age.

Reframing the Approach: Single-Tasking as a Superpower

One of the most powerful strategies for improving performance on complex tasks is to stop multitasking entirely. Focusing on one task at a time, or "single-tasking," allows the brain to dedicate its full cognitive resources to the job, leading to better quality work and reduced stress. For older adults, who may be more susceptible to distraction from "internal chatter," this approach is especially beneficial.

Practical single-tasking techniques

• Prioritize with a daily list. Each morning, identify 3-5 crucial tasks and focus on them first. This prevents feeling overwhelmed by a long to-do list.
• Time-block your day. Dedicate specific, uninterrupted blocks of time to specific tasks. For example, set aside 30 minutes to pay bills or an hour for gardening.
• Utilize the "one-minute rule." If a task takes less than a minute to complete (e.g., putting away a dish, sending a quick email), do it immediately to prevent small tasks from piling up and creating mental clutter.
• Practice mindful task engagement. When you find yourself switching tasks, use a brief mindfulness exercise, like focusing on your breathing for a moment, to reset and deliberately re-engage with your primary task.

Creating an Environment Conducive to Focus

Your surroundings have a significant impact on your ability to concentrate. For older adults, whose brains may have more difficulty filtering out irrelevant stimuli, a distraction-free environment is critical.

Simple environmental adjustments

• Eliminate digital distractions. Turn off notifications on phones and computers while working on a focused task. Silence your phone or leave it in another room.
• Declutter your workspace. A clean, organized physical space can lead to a less cluttered mind. Clear your desk of unnecessary papers and objects to reduce visual stimuli.
• Control ambient noise. For some, complete silence is best, while others prefer soft instrumental music. Consider noise-canceling headphones to block out distracting sounds.
• Adjust lighting. Older eyes require more light for the same quality of vision. Ensure your workspace is well-lit with non-glare task lighting to reduce strain.

Strengthening Cognitive Skills with Training

Just as physical exercise strengthens muscles, mental exercise can enhance brain function. Research has shown that specific types of cognitive training can improve attention and task-switching abilities in older adults.

Cognitive exercises for better focus

• Dual-task training: Practice combining a cognitive and a motor task. For example, walk while counting backward from 100 by sevens, or balance on one leg while reciting the alphabet.
• Computerized games: Studies have found that playing targeted cognitive video games can improve multitasking skills and memory in older adults, sometimes even surpassing the abilities of younger participants.
• Learning new skills: Taking up a new hobby that requires concentration, like learning a musical instrument, a new language, or complex crafts like quilting, can build new neural pathways and improve cognitive flexibility.

Enhancing Overall Brain Health

A healthy lifestyle is the foundation of strong cognitive function. Several daily habits can help support a sharper, more focused mind.

Lifestyle factors for improved multitasking ability

• Prioritize sleep. Aim for 7-9 hours of quality sleep per night. Sleep is essential for memory consolidation and cognitive processing.
• Stay physically active. Regular aerobic exercise, like brisk walking or swimming, increases blood flow to the brain's prefrontal cortex, which is vital for concentration.
• Adopt a brain-healthy diet. A diet rich in fruits, vegetables, healthy fats (like those in fish and nuts), and whole grains supports cognitive function. The Mediterranean diet and MIND diet have shown particular benefits.
• Manage stress. Chronic stress can impair executive function. Mindfulness and meditation techniques can help calm the mind and improve focus.
• Stay socially engaged. Social interaction provides mental stimulation and can reduce the risk of cognitive decline associated with loneliness and isolation.
