A widower who lost his wife after 55 years of marriage has been struggling with depression. His daughter worries he’ll become ill. He reassures her that everyone who loses a long-time spouse feels depressed, and that she should just give him time.
He’s right that losing a spouse represents one of life’s most difficult transitions, and that time helps heal a broken heart. But his daughter’s concern is also valid. Depression can lead to physical illness in older adults—and research proves it.
The Depression-Diabetes Connection
A landmark study published in the April 23, 2007, issue of Archives of Internal Medicine (now JAMA Internal Medicine) found that older adults experiencing depressive symptoms—whether occurring once, increasing in frequency, or remaining steady over 10 years—were significantly more likely to develop diabetes than those without depression.
The Feinberg School of Medicine at Northwestern University studied participants who were evaluated annually for 10 depression symptoms related to mood, irritability, appetite, concentration, and sleep. At the study’s start, the average depression score was 4.5, with one-fifth of participants scoring eight or higher. During follow-up, scores increased by at least five points in nearly half of the participants, and 234 individuals developed diabetes.
More recent research confirms that depression and type 2 diabetes affect each other in both directions—depression increases diabetes risk, and diabetes increases depression risk. This bidirectional relationship complicates both conditions, affecting self-care, glycemic control, complications, and quality of life.
At the time of the original study, two million older adults experienced depression, and 15.3% of those over 65 had diabetes. Today, both conditions remain significant concerns for Canadian seniors.
Recognizing Depression in Older Adults
Depression symptoms in seniors often differ from those in younger adults. Watch for:
- Persistent sad, anxious, or “empty” mood
- Loss of interest in previously enjoyed activities
- Decreased energy and fatigue
- Difficulty concentrating or making decisions
- Sleep disturbances (insomnia or oversleeping)
- Changes in appetite or weight
- Feelings of guilt, worthlessness, or helplessness
- Feelings of hopelessness or pessimism
- Irritability or restlessness
- Recurring aches and pains that don’t respond to treatment
The Canadian Coalition for Seniors’ Mental Health provides comprehensive resources on depression in older adults. Their updated 2021 Canadian Guidelines offer evidence-based approaches to prevention, assessment, and treatment.
The Canadian Psychological Association’s fact sheet on depression among seniors offers symptom lists and treatment discussions appropriate for families. CORE Alberta’s depression resources include brochures, videos, and practical tools for seniors and caregivers.
Why Depression Leads to Physical Illness
Depression doesn’t just affect mood—it impacts the entire body. The stress hormone cortisol increases, inflammation rises, immune function decreases, and behaviours that protect health (like exercise, proper nutrition, and medication adherence) often deteriorate.
For seniors already managing chronic conditions, depression compounds the challenge. A depressed senior may stop taking medications correctly, skip medical appointments, eat poorly, and withdraw from physical activity—all factors that accelerate physical decline.
The Power of Companionship
One of the most effective ways to combat depression is through meaningful social connections. Though seniors may initially resist, encouraging them to reconnect with old friends and establish new relationships makes a significant difference.
Where to Start:
- Family gatherings and regular visits
- Faith communities and places of worship
- Neighbourhood activities and local senior centers
- Hobby groups and volunteer opportunities
- Regular phone or video calls with distant loved ones
For seniors experiencing isolation or mobility limitations that make social connections difficult, professional companionship provides essential support. Canadian mental health resources for seniors include both clinical supports and community programs.
When Professional Support Helps
If your parent or older loved one shows signs of depression, especially following major life changes like losing a spouse, professional help may be needed. This can include:
- Consultation with their family doctor
- Referral to a geriatric psychiatrist or psychologist
- Participation in senior support groups
- Professional companion care for daily social connection
