We often hear phrases like “stay strong”, “move on”, or “keep it to yourself.”
But what happens when emotional suppression becomes a long-term coping style?
A Finnish population-based study (by researchers at Karolinska Institutet and collaborators including Miia Kivipelto, Inna Lisko, Tiia Ngandu, Alina Solomon et al) presented in Alzheimer’s & Dementia examined over 1,100 older adults and found an association between chronic emotional suppression and higher risk of dementia later in life.
Importantly:
• This study shows association, not causation
• The findings need further replication
• Emotional expression does not mean emotional impulsivity
What the research does reinforce is something mental health professionals increasingly recognize:
our emotional wellbeing and brain health are deeply interconnected.
Chronic stress, loneliness, unresolved emotional distress, poor sleep, depression, inflammation, and social withdrawal may all influence long-term cognitive health.
Protecting the brain is not only about memory exercises and medications. It is also about meaningful relationships, emotional processing, stress management, movement, sleep, and holistic wellbeing.
