Hidden Red Flags: 10 Subtle Signs of Dementia You Need to Recognize Now
7. Changes in Sleep Patterns
A good night’s sleep gets trickier as we age, but when sleep patterns shift dramatically—or rest becomes elusive despite best efforts—it’s worth a closer look. Early dementia can disrupt the natural rhythms of rest and wakefulness, leading to sudden late-night wandering, regular insomnia, or increased daytime sleepiness. While occasional tossing and turning is common, what stands out here is the newness and persistence of change. Someone might wake up more often, reverse day and night schedules, or even become restless in the evenings, a phenomenon known as “sundowning.” If you find yourself hearing about frequent overnight pacing, or you’re noticing confusion or fatigue upon waking, bring this up gently. It may be tempting to chalk it up to aging or stress, but if these patterns stick around, they may be part of the bigger picture. Open, curious conversation—free of judgment—can be the first step toward sleep solutions (and peace of mind).
8. Noticeable Personality or Mood Changes
Perhaps the most easily missed red flag of all: subtle but significant changes in how someone reacts or relates to the world. Where a loved one was once outgoing and easygoing, you might suddenly see irritability, anxiety, or discomfort in social settings. Suspicion or withdrawal replaces enthusiasm, or someone who’s always been patient becomes uncharacteristically snappy or upset. These shifts aren’t a reflection of anyone’s character—they’re among the earliest ways dementia can affect emotional processing. Often, those experiencing these changes aren’t fully aware of them, making gentle observation and loving support crucial. If a calm demeanor morphs into nervousness, or if once-strong relationships become strained, pause before assuming it’s just routine stress. Noticing the “why” behind the change, and responding with warmth rather than worry, opens the door for genuine connection and help. Remember: these are symptoms, not shortcomings, and deserve compassion above all else.
