COGNITIVE WELLNESS AND MENTAL HEALTH
Mental health is a state of mental well-being refers to a positive state of emotional,
psychological, and social health. It is characterised by a sense of contentment, resilience,
and the ability to effectively cope with life’s challenges. Mental well-being encompasses
positive emotions, a sense of purpose, and the capacity to engage in fulfilling relationships
and activities.1,2
Mental health and brain health involve the harmonious coordination of cognitive, emotional,
social, and behavioural functions.3 The different aspects of brain health include
cognitive, motor (movement), emotional, tactile and sensory functions.4
Various factors can affect brain health, including:4
- age-related changes in the brain
- injuries such as stroke or traumatic brain injury
- mood disorders such as depression
- substance use disorder or addiction
- diseases such as Alzheimer’s and related dementias
Understanding Cognitive Health
Cognitive health is not just about memory or intelligence; it encompasses a broad
range of mental abilities. These include:5
- Memory: The ability to retain and recall information.
- Attention: The capacity to focus on tasks and ignore distractions.
- Language: Communication skills and comprehension.
- Problem-solving: Logical thinking and decision-making abilities.
- Executive function: Planning, organising, and managing time effectively.
Maintaining optimal cognitive health is essential for a fulfilling life, as it directly impacts
how we learn, work, interact with others, and navigate daily challenges.5
Depression and Cognitive Deficits
Depression is an example of a mood disorder that can cause cognitive symptoms such
as:6
- Negative or distorted thinking
- Difficulty concentrating
- Distractibility
- Forgetfulness
- Reduced reaction time
- Memory loss
- Indecisiveness
These symptoms can interfere with various areas of a person’s life, including work,
school and relationships.6
Certain antidepressants, such as bupropion, has been shown to improve cognitive function
in major depression. After eight weeks of treatment, it improved memory (visual and
verbal) and executive functioning.7
Strategies for Enhancing Cognitive Health
Certain lifestyle choices can help promote cognitive wellness. These include:5
- Regular physical exercise such as walking, strength training and aerobic exercises.
Exercise increases blood flow to the brain, stimulates the growth of new brain cells,
and enhances the connections between them.
- Nutrition plays a vital role in cognitive health. A diet rich in fruits, vegetables, whole
grains, lean proteins, and healthy fats (such as omega-3 fatty acids) provides essential
nutrients that support brain function. Sugar, saturated fats, and processed foods
should be limited as they can impair cognitive abilities over time.
- Sleep is essential for cognitive function, memory consolidation, and emotional
well-being. Aim for 7-9 hours of quality sleep each night.
- Mental stimulation through activities that challenge the brain. These include learning
a new skill or language, solving puzzles or brain teasers, reading books, playing
musical instruments, or participating in intellectually stimulating conversations.
- Stress management. Chronic stress can have detrimental effects on cognitive
function. Stress-reducing techniques such as mindfulness meditation, deep breathing
exercises, yoga, or spending time in nature help lower cortisol levels, improve mood,
and enhance cognitive resilience.
- Social Engagement. Maintaining social connections and participating in meaningful
social activities are vital for cognitive health. Social interaction stimulates brain
activity, reduces feelings of loneliness and depression, and improves overall mental
well-being.
- Seeking professional help for mental health concerns such as anxiety, depression,
or cognitive decline is crucial. Therapy, counselling, or medication can
effectively manage these conditions and improve cognitive function. It is essential to
prioritise mental health and seek support when needed.
In today’s fast-paced world, where cognitive demands are high and distractions are plentiful,
prioritising cognitive health is more important than ever. Pharmacists are ideally
positioned to advise patients on effective strategies and encourage them to make it part
of their daily routine to support brain health and function, leading to improved quality of
life and overall well-being.
