For most of us, the daily progression of light to dark is a calming natural progression, but for some people, the darkening afternoon light can bring on a medical condition in which patients exhibit agitation, fear and confusion. Known as Sundowners Syndrome, this medical condition is most likely to occur in those suffering from dementia.
While each person is different, the most common early symptoms of Sundowners Syndrome include restlessness, agitation, irritability and mental confusion that begins in the late afternoon and continues during the night. Over time, patients may progress from subtle, inconsistent symptoms to more pronounced changes in behavior. Other noticeable behaviors include confusion, pacing, yelling, mood swings, fear and anxiety.
Sundowning is most often triggered by interruptions to the circadian rhythm or “biological clock” that helps a person know when to wake and sleep. As light patterns in the day change, the mind has more difficulty coping with those changes. Patients with mid to late stage Alzheimer’s are more likely to exhibit these symptoms. Some medications may cause a dementia – like reaction so it is important to be aware of what medications the person is taking and possible side effects.
Regular exercise, adequate sleep and other remedial actions can lessen Sundowning behaviors and symptoms, making care for the patient more manageable. However, because Sundowning is part of a larger dementia diagnosis, there is no permanent solution.
Anytime a patient shows significant changes in symptoms, medical advice should be sought to make sure there are no other underlying medical conditions. If Sundowning symptoms become problematic for a caregiver, medical advice can help find solutions.
Perhaps the most important way to help manage Sundowners Syndrome is to maintain a calm, quiet atmosphere in the early evening. Provide adequate lighting during the day and close curtains in the evening to minimize shadows. Have the patient maintain a regular schedule including regular meals, exercise and bedtimes. Limit caffeine and alcohol. Be aware of how stress affects those who are caregivers and provide for respite care.
