How to Spot Signs of Mental Illness in the Elderly

Aging brings change—new routines, new limitations, and sometimes new health concerns. But when an older loved one starts acting very differently, it can be hard to tell what's part of normal aging and what might be something more. Subtle shifts in mood, behavior, or thinking are often brushed off as "just getting older," yet these changes can be early warning signs of mental illness. 

"Mental health conditions in older adults are often underrecognized," says Eugene Sun, MD, psychiatrist at Archbold Northside in Thomasville, Georgia. "Because symptoms can look like normal aging or overlap with medical issues, they may go untreated longer than they should."

Understanding what to look for and when to seek help can make a life-changing difference for seniors and their families who love them.

Mental Illness in Older Adults: More Common Than You Think

Mental health conditions are not a normal part of aging, but they are common among older adults. Depression, anxiety, dementia-related mood changes, and other psychiatric disorders can develop later in life or resurface after years without symptoms. 

"Major life changes such as retirement, loss of independence, chronic illness, or grief can all increase vulnerability to mental health concerns," explains Dr. Sun. "These stressors can affect emotional well-being in powerful ways."

Because seniors may be less likely to talk openly about their mental health—or may not recognize symptoms themselves—family members often play a critical role in identifying when something isn't right. 

Emotional and Mood changes to Watch For

One of the earliest indicators of mental illness in the elderly is a noticeable change in mood or emotional expression. These changes may occur gradually or suddenly. 

Common emotional warning signs include: 

• Persistent sadness, hopelessness, or tearfulness
• Increased irritability, anger, or frustration
• Loss of interest in hobbies, social activities, or family time
• Anxiety, excessive worry, or fearfulness
• Emotional flatness or withdrawal

"Depression in older adults doesn't always look like sadness," says Dr. Sun. "It may show up as apathy, irritability, or a lack of motivation rather than overt low mood."

Behavioral Changes That May Signal a Problem

Changes in behavior are often easier for loved ones to spot. When an older adult begins acting differently than they have for years, it's worth paying attention. 

Behavioral red flags can include: 

• Social isolation or avoiding previously enjoyed activities
• Changes in sleep patterns, including insomnia or sleeping excessively
• Changes in appetite or significant weight loss/gain
• Neglecting personal hygiene or daily responsibilities
• Increased use of alcohol or medications

"These behaviors are often mistaken for personality changes or stubbornness," Dr. Sun notes. "In reality, they may reflect an underlying psychiatric condition that needs attention."

Cognitive and Memory-Related Warning Signs

Not all memory changes are part of normal aging. While occasional forgetfulness is expected, more concerning cognitive symptoms may point to depression, anxiety, or other mental health disorders, sometimes alongside dementia. 

Warning signs include:

• Confusion or disorientation
• Difficulty concentrating or making decisions
• Increased forgetfulness that interferes with daily life
• Paranoia, suspiciousness, or false beliefs
• Hallucinations or seeing/hearing things that aren't there

"Mental illness can significantly affect thinking and perception," says Dr. Sun. "early evaluation helps us determine what's happening and how best to support the patient."

Physical Symptoms with No Clear Medical Cause

Mental health conditions in older adults often present with physical complaints rather than emotional ones. Seniors may visit their primary care provider repeatedly for symptoms that don't have a clear medical explanation. 

These may include: 

• Chronic pain
• Fatigue or low energy
• Digestive issues
• Headaches or body aches

"When physical symptoms persist despite treatment, it's important to consider mental health as part of the picture," Dr. Sun explains. 

When It's Time to Seek Professional Help

If symptoms last more than a few weeks, worsen over time, or begin interfering with daily life, it's time to seek professional support. Immediate help is needed if an older adult expresses thoughts of self-harm, severe confusion, or poses a danger to themselves or others. 

"Early intervention leads to better outcomes," says Dr. Sun. "Mental health treatment can significantly improve quality of life, even later in life."
