Moving from one season to another can have a noticeable impact on someone with Alzheimer’s disease, affecting their behavior, mood, and overall well-being. Seasonal changes often bring shifts in daylight, temperature, and routine, all of which can influence symptoms in people living with Alzheimer’s.
One common effect is on sleep patterns. For example, shorter daylight hours in fall and winter can worsen sleep disturbances, which are already common in Alzheimer’s. This can lead to increased confusion, irritability, and a phenomenon called sundowning, where symptoms worsen in the late afternoon or evening. Conversely, longer daylight in spring and summer may help improve sleep but can also bring challenges like heat-related discomfort.
Changes in routine and environment that come with seasons can also be unsettling. People with Alzheimer’s often rely on familiar patterns, and disruptions—such as adjusting to daylight saving time or new weather conditions—can increase anxiety or agitation. Seasonal allergies or illnesses more common in certain times of the year may further affect cognitive function and mood.
Additionally, hormonal changes linked to seasons, especially in women, can influence sleep quality and cognitive symptoms. For example, menopause-related sleep issues can compound Alzheimer’s symptoms, making seasonal transitions more difficult.
Caregivers and care teams need to be aware of these seasonal effects to adjust care plans accordingly. This might include managing lighting to reduce sundowning, ensuring comfortable temperatures, maintaining consistent routines, and addressing sleep problems proactively.
Overall, the shift from one season to another can subtly but significantly affect someone with Alzheimer’s, requiring thoughtful attention to help maintain their comfort and cognitive health.
