Are your loved ones acting strange?

What is it?

Unusual behaviour in older adults refers to noticeable changes in actions, emotions, or thought patterns that are not typical for the person. These behaviours may appear suddenly or gradually and can include confusion, aggression, withdrawal, inappropriate social actions, or repetitive habits. They are often signs of underlying physical, mental, or neurological conditions—not just “normal aging.”

Prevalence and statistics

• Studies suggest that up to 20–30% of older adults may exhibit changes in behavior,

• 1 in 5 adults will experience a noticeable change in behaviour due to mental health conditions during their lifetime.

• Up to 90% of individuals with dementia exhibit behavioural and psychological symptoms, including agitation, aggression, or withdrawal.

• 60% of caregivers report behavioural changes like mood swings or loss of interest as the first noticeable signs of mental decline in elderly loved ones.
