How to Improve Cognitive Function: 6 Exercises & Tests

Cognitive health is increasingly recognized as a key component of overall health and wellness (Bart et al., 2018).

As with other dimensions of health and wellness, deliberate effort is needed to maintain and especially improve cognitive health.

In this article, we discuss key factors and exercises that can improve cognitive function and help sustain cognitive health across the lifespan.

These science-based exercises will explore fundamental aspects of positive psychology including strengths, values, and self-compassion, and will give you the tools to enhance the wellbeing of your clients, students, or employees.

Strengths-Based Approach to Cognitive Health

For much of their history, psychiatry, clinical psychology, and related disciplines like counseling focused on treating our deficits, rather than developing our strengths.

This focus on deficits began to shift dramatically with the advent of positive psychology.

With the positive psychology movement in the late 1990s came a focus on finding and developing an individual’s strengths and using these to overcome any deficits (Diener, 2009).

In the realm of cognition, this entailed finding areas of thinking, memory, and problem solving that were relative strengths for an individual.

For example, you might find that abilities such as sustained attention and organization are among your most notable cognitive strengths. You might also note the presence of external factors supporting your cognition, such as a healthy diet, regular exercise, and good sleep habits.

In taking careful inventory of your cognitive strengths, you are in the best position to enhance and deploy them, improving your cognitive health and function.

How to Improve Cognitive Function 101

The first principle to follow here is recognizing the importance of a healthy body/brain for optimal cognitive health.

Researchers at Harvard Medical School have cited six key factors in maintaining a healthy body/brain (adapted from Harvard Health Publishing, 2021):

• A plant-based diet rich in fruits, vegetables, and grains
• Regular exercise
• Good sleep habits
• Stress reduction
• Social involvement
• Challenging your brain

The Harvard researchers emphasize the importance of cultivating these factors together, as they reinforce each other and lead to optimal brain and cognitive health.

The first four factors – concerning diet, exercise, sleep, and stress reduction – can be seen as indirect support for cognitive health. Together, they represent the “healthy mind in a healthy body” principle.

The last two factors, social interaction and challenging the brain, involve cognition more directly.

Social interaction stimulates and challenges the brain in ways that solitary activities cannot. It draws on multiple skills, such as visual-spatial processing of faces and gestures, inferring others’ motivations, decision making about how to behave within social norms, etc.

Individuals with broader and more complex social networks seem to have larger or more developed amygdala and related brain structures (Bickart, Wright, Dautoff, Dickerson, & Barrett, 2011).

The amygdala and related structures are deep brain areas crucial for regulating emotions and facilitating memory storage. This and similar studies suggest a strong association between social interaction and brain health in these crucial areas.

Maintaining or expanding your social network can, therefore, help ensure overall brain and cognitive health.

Challenging the brain with specific activities is the second, more direct means toward cognitive health, such as with the following cognitive exercises and games.

Enhancing Cognitive Health: 6 Exercises & Games

There are various high-tech cognitive exercises available through paid programs such as Lumosity. Such programs offer digitally based brain exercises for most ages and ability levels.

However, there are also relatively low-tech, low-cost, effective options for cognitive strengthening, available to most individuals with some ingenuity and effort. Harvard Medical School has outlined several of these (Godman, 2021), including the following:

• Learn a new language
  This can help with mental agility and be neuro-protective, since a new language forges new connections among neurons, making them more resistant to disease (Kroll, Dussias, Bice, & Perrotti, 2015).
• Listen to or make music
  Music activates multiple brain areas, including those that process emotions, memory, and movement (Wan & Schlaug, 2010). There are many free online sites for listening to and learning to play music.
• Cards, board games, and electronic games
  Card games are a cheap and fun way to exercise memory and strategy skills. Board games like Trivial Pursuit build memory for facts, while games like Monopoly exercise math, financial, and strategy skills. Strategy and 3D adventure video games have been shown to have significant benefits for attention, short-term memory, and reaction time (Brilliant T, Nouchi, & Kawashima, 2019).
• Travel
  Whether to near or far destinations, travel exposes us to new sights, sounds, and experiences that build new connections between neurons, including the so-called “place cells” in the brain’s memory circuits (Eichenbaum, Dudchenko, Wood, Shapiro, & Tanila, 1999).
• Cultural consumption
  Take in films, plays, poetry readings, museum tours, etc. The newer and more unusual these are for you (for example, seeing a foreign film, visiting a new museum, or reading a poet you haven’t read before), the more challenging and stimulating they will be for your brain and the more new connections you will establish between neurons (Park & Huang, 2010). Culture can wire and rewire the brain, a process that continues throughout our lives.
• Puzzles
  Puzzles are meant to challenge the brain. They also draw on the brain’s natural tendencies to perceive patterns, complete sequences, and solve problems (Fissler et al., 2018).

How to Maintain Cognitive Fitness in Older Age

The supportive factors, exercises, and games cited above remain valid for maintaining cognitive fitness as we grow older, with certain caveats.

Just as with any other population, it is crucial to find a challenge for older adults that is “just right” so that the individual’s abilities are stimulated but not overwhelmed (Proffitt, 2016).

For example, a verbal memory task for an older person with encroaching memory problems might be modified to include a 6-item list of words to recall, instead of a 12-item list. Prompts and cues can spur memory and provide the individual with an experience of success.

If a cognitive task is too easy, it will not serve to strengthen a person’s abilities. If it is too hard, you risk overwhelming the person. This is especially true of people with encroaching Alzheimer’s disease, the most common dementing condition in the elderly (Desai & Grossberg, 2001).

Finding the right cognitive challenge for such individuals allows them to exercise their faculties and experience some success, rather than becoming overwhelmed and frustrated.

Testing Cognitive Fitness: 5 Health Assessments

Neuropsychological testing is one way to assess cognitive health. However, this option can be costly and labor intensive. In many cases, basic screening will suffice for an understanding of a given individual’s cognitive health status (Wasserman, Anderson, & Schwartz, 2016).

There are a number of excellent tools available to practitioners for basic screening and tracking of cognitive health. Many of these tools are designed for use with older people, but some are meant for use with younger people as well.

The Alzheimer’s Association website offers a cognitive assessment toolkit that includes the Medicare Annual Wellness Visit algorithm for the assessment of cognition. This assessment uses patient history, observations by clinicians, and concerns raised by the patient, family, or caregivers.

The toolkit further includes three measures validated for use by professionals to assess and track a patient’s cognitive health. These measures include the General Practitioner Assessment of Cognition, Memory Impairment Screen, and the Mini-Cog brief psychometric test.

Each of the above measures has the following advantages (Alzheimer’s Association, n.d.):

• Can be given in five minutes or less
• Equal or superior to the popular Mini-Mental State Exam for detecting dementia
• Easily administered by non-physician health practitioners
• Relatively free from educational, language, and cultural bias

For younger individuals, the Montreal Assessment of Cognition is a widely used instrument that has been validated for cognitive screening in people between 14 and 21 years old (Pike, Poulsen, & Woo, 2017).

Other basic screenings have been used to assess cognitive function in youth with conditions such as epilepsy (Asato, Doss, & Plioplys, 2015) and brain injury (Rasquin et al., 2011).

In designing a cognitive health screening for any age group, it’s important to keep the following considerations in mind (adapted from Wasserman et al., 2016):

• What level of training or expertise is required for the professionals giving the screening measure? A good screening should be one that can be administered with a minimum of training.
• How often will the screening be used? At what time intervals?
• Can the screening be billed to insurance?
• What supplies – paper forms, computer programs, etc. – are needed to do the screening?
• How will the screening results be communicated to examinees?
• What decisions, if any, will be based on screening results? These might include referrals for more in-depth testing or cognitive enhancement or rehabilitation exercises.

Can Supplements Help Maintain Cognitive Health?

Supplementary medications are those used to complement our food or medication intake but are not (yet) approved for diagnosing, treating, curing, or preventing any disease (Gestuvo & Hung, 2012).

These supplements include B-complex and E vitamins, minerals such as zinc, herbs such as ginkgo biloba, and other botanicals.

Such supplements are commonly used among all age groups, especially in developed countries (Gestuvo & Hung, 2012).

Evidence for the efficacy of supplements in maintaining cognitive health has been mixed.

The Ginkgo Evaluation of Memory study followed 3,069 older adult participants over the course of six years, randomly assigned to ginkgo biloba or placebo groups (DeKosky et al., 2008). The study found no evidence that the supplement slowed cognitive decline or prevented dementia.

Further, some researchers have warned that ginkgo biloba’s blood-thinning properties might interact negatively with anticoagulant medication and produce excess bleeding (Qato et al., 2008).

B-complex vitamins such as B6, B9, and B12 have not been shown to prevent or slow cognitive decline in older adults (McMahon et al., 2006).

Studies have shown that certain supplements such as zinc can have positive effects on frontal or executive function in children and adults (Warthon-Medina et al., 2015).

Recently, a large prospective cohort study followed 5,395 participants for 9.6 years and found that those with the highest intake of vitamin-E-rich foods were 25% less likely to develop dementia than the third of the group with the lowest vitamin E intake (Devore et al., 2010).

As always, it is best to consult your physician before taking either approved medications or medical supplements.

A Take-Home Message

For much of their history, clinical psychology and related helping professions focused on assessing and treating emotional, social, and cognitive deficits.

With the positive psychology movement in the late 1990s came a different emphasis: finding and building upon strengths.

Aspects of health and wellbeing began to be studied more assiduously and became the focus of interventions. Initially, cognitive health was one aspect of overall health and wellbeing that was overlooked by many researchers and practitioners.

Fortunately, more recently, cognitive health has begun to receive the attention it deserves, as both a research topic and focus of intervention (Aidman, 2020).

As with other components of health and wellness, cognitive health, including attentional capacity, memory abilities, and organizational and problem-solving skills, can be enhanced with the right support and exercises.

Staying physically healthy pays large dividends toward such cognitive fitness. Physical health includes maintaining a heart-healthy diet, sleeping well, and exercising regularly.

In addition, basic, cost-effective mental activities and exercises can further boost cognitive fitness. Many of these are enjoyable in their own right and can boost cognitive skills. These include listening to or making music; doing puzzles; playing card, board, or video games; cultural consumption such as seeing films and reading novels; and nature walks for forest bathing (Wen, Yan, Pan, Gu, & Liu, 2019).

To be most effective, cognitive activities and exercises should involve as much novelty as possible. This will ensure that maximum nerve growth or neuroplasticity takes place, in response to new stimuli (Park & Huang, 2010).

It is also important that cognitive activities and exercises provide “just-right challenges” for the individual involved – neither too easy nor too difficult.

To find the right activities, a positive psychology, strengths-based approach might be useful. Such an approach builds awareness of our strengths and encourages their use in overcoming obstacles and reaching goals – the “just-right challenges.”
