This weekend, we turned our clocks back an hour. For most of us, that's a minor inconvenience. But for someone living with dementia, that shift can affect sleep, routines, orientation, and behavior. Here are six things I'd encourage caregivers to watch for and a few simple adjustments that may help. Six things to know and do 1. Earlier darkness may increase confusion. Some people experience increased restlessness, anxiety, or disorientation as daylight fades, often called sundowning. Turn lights on before the room becomes dim, rather than waiting until it's dark. 2. Their internal clock doesn't automatically reset. Someone accustomed to eating at 5 p.m. may be hungry at 4 p.m. after the change. Watch their cues instead of insisting on the new clock time. 3. Sleep patterns may shift. Earlier waking, daytime fatigue, or increased nighttime activity can occur. Preserve familiar bedtime routines, provide morning daylight, and avoid unnecessarily long late-day naps. 4. Plan activities around their best time of day. If late afternoons are already difficult, move appointments, bathing, errands, and other demanding tasks earlier when possible. 5. Be attentive to safety as darkness arrives earlier. Shadows can affect perception, and poor lighting can increase disorientation and fall risks. Check hallways, bathrooms, stairs, and frequently traveled routes. Use nightlights where appropriate. 6. Observe before attributing changes to dementia. Notice when difficulties occur, what happened beforehand, and what improves the situation. Don't assume every change is sundowning. Sudden or marked changes in cognition or behavior need medical attention. These recommendations align with the Alzheimer's Association and National Institute on Aging guidance on sleep, lighting, routines, and sundowning. Remember, the clock changes overnight, but the person you're caring for may need more time to adjust. Before you assume that increased confusion or restlessness means their dementia is getting worse, look at what has changed around them.
