Sundowning, or sundown syndrome, is a group of behaviours, feelings and thoughts that people with Alzheimer's or dementia experience as the sun sets. While it is most common in people with Alzheimer's and other forms of dementia, it can also develop in older adults without dementia in hospitals. The exact cause of sundowning is not known, but it could be related to tiredness, a lack of light, medication, or a problem with the internal body clock. Symptoms of sundowning include confusion, agitation, aggression, hallucinations, and delusions. Treatment options include medication and environmental changes, such as reducing noise and increasing light in the late afternoon and early evening.

Sundowning is common in people with Alzheimer's and other forms of dementia
Sundowning is a set of symptoms or behaviours that affect people with Alzheimer's and other forms of dementia. It is characterised by increased confusion, anxiety, agitation, hallucinations, pacing, disorientation, and sleep issues. Sundowning typically occurs in the late afternoon or evening, although it can potentially occur at any time. Around 20% of people diagnosed with Alzheimer's experience sundowning at some point.
The exact cause of sundowning is not fully understood, but several factors have been proposed. One theory suggests that it may be related to changes in the brain that affect the internal body clock. Other potential factors include tiredness, a lack of light, medication side effects, or problems with the individual's internal body clock. Low lighting and shadows in the late day can cause confusion and anxiety, and it can be hard to distinguish dreams from reality.
To help manage sundowning symptoms, caregivers can implement various strategies. These include ensuring adequate rest at night, avoiding caffeinated and alcoholic drinks late in the day, encouraging sunlight exposure and daily exercise, and keeping a consistent daily routine with minimal overstimulation. Additionally, creating a calm and safe environment, reducing noise, playing soothing music, and providing reassurance can help ease sundowning behaviours.
Medications can also be used to treat sundowning symptoms, including antidepressants, antianxiety medications, antipsychotics (with caution), and melatonin for sleep. Support groups are available for caregivers of people with Alzheimer's, as caring for someone with sundowning can be overwhelming. Identifying and addressing triggers, such as overstimulation or specific environments, can also help manage sundowning behaviours.

It can be caused by tiredness, lack of light, medication, or a disrupted body clock
Sundowning is a group of symptoms, including confusion, anxiety, hallucinations, and wandering, that occur in people with Alzheimer's and dementia as the day closes. It can also affect older adults without dementia, particularly in hospitals, where the prevalence of sundowning ranges from 10% to 20%.
The syndrome can be caused by several factors, including tiredness, lack of light, medication, and a disrupted body clock. Tiredness can be a trigger, so ensuring a good night's rest is essential. A short nap early in the day can be beneficial, but avoid caffeine after the morning and limit alcohol.
Lack of light or diminished natural light in the evening can aggravate symptoms. Light therapy has been suggested as a treatment, with increased lighting in the evening potentially helping to re-orient elderly patients. Changes in lighting throughout the day, such as the transition from daylight to twilight, can also trigger sundowning.
Medications can play a role in causing sundowning. While certain medications can be used to treat the symptoms, such as antidepressants, anti-anxiety medications, and antipsychotics, polypharmacy or changes in medication can also act as precipitating factors.
Finally, sundowning is often associated with a disrupted body clock or circadian rhythm. This can be influenced by the amount and duration of sunlight, with an increased incidence during fall or winter when daylight hours are shorter. Maintaining a consistent routine and sleep schedule can help prevent sundowning.

Symptoms include confusion, agitation, restlessness, hallucinations, and aggression
Sundowning, also known as sundowner's syndrome, is a set of symptoms or behaviours that people with Alzheimer's or dementia experience. While sundowning is most common in people with these conditions, older adults without dementia can sometimes develop it in the hospital. The lack of sensory stimulation in a hospital room can cause disorientation and confusion, which are both symptoms of sundowning.
Symptoms of sundowning include confusion, agitation, restlessness, hallucinations, and aggression. People with sundowning may become more nervous and upset, and confused as the day closes, and they might have trouble calming down. Agitation can make it hard for them to get to sleep. They may also experience hallucinations, which happen due to brain damage from dementia. Some people with Alzheimer's also have delusions or false beliefs. For example, they may think their neighbour is stealing from them or that the government is watching them.
Restlessness is another symptom of sundowning. People with sundowning may pace back and forth or shadow their caregiver by following them everywhere they go. They may also become aggressive, so it is important to take away or lock up anything that could be used as a weapon. If they become violent, caregivers should stop what they are doing and back away, calling for help if necessary.
Confusion is a common symptom of sundowning, and it can be made worse by low lighting or shadows, which may cause the person to become confused by what they see. Disorientation and changes in the person's environment can also trigger confusion.

Treatments include medication, light therapy, exercise, and maintaining a routine
Sundowning refers to a group of behaviours, feelings and thoughts experienced by people with Alzheimer's or dementia. It usually occurs at sunset or as the sun goes down, but it can also happen at any time of the day. Symptoms include insomnia, anxiety, pacing, hallucinations, paranoia, confusion, irritability, delusions, restlessness, and rocking in a chair.
Treatments for sundowning include:
Medication
Medications can be used to treat the individual behaviours, feelings and thoughts associated with sundowning. Antidepressants, antianxiety medications and antipsychotics can be used, but with caution, due to the long-term risks of stroke. Melatonin can also be prescribed to aid sleep.
Light Therapy
Light therapy can be used to treat sundowning. It is important to ensure that the person suffering from sundowning gets adequate lighting during the day and darkness at bedtime. It is also beneficial for them to get plenty of natural sunlight by sitting by a window or going out for walks.
Exercise
Daily exercise can help ease the symptoms of sundowning. It is also important to ensure the person gets enough rest at night and, if necessary, takes a short nap early in the day.
Maintaining a Routine
Creating a simple, consistent routine can help prevent sundowning and lessen its severity. This includes limiting caffeine after the morning, avoiding too much alcohol, and planning activities throughout the day. It is also important to address the underlying triggers of sundowning, such as disrupted circadian rhythms, dehydration, side effects of medications, and physical illnesses.

Hospitals should work to prevent sundowning and delirium in elderly patients
Sundowning is a group of behaviours, feelings and thoughts that people with Alzheimer's or dementia experience as the sun sets. It can also affect older adults without dementia, particularly in hospitals due to the lack of sensory stimulation in a hospital room. As the sun sets, elderly patients can become confused, agitated, disoriented, and even hallucinate. They may become more nervous and upset in the afternoon or evening, and this can make it hard for them to get to sleep.
Delirium is similar to sundowning, but it comes and goes throughout the day. It is characterised by confusion and a lack of awareness of one's surroundings. Sundowning and delirium can be prevented and treated in hospitals with a few measures. Firstly, it is important to ensure that patients have access to their eyeglasses, hearing aids, and dentures, which can help them stay involved and oriented. Familiar objects, pictures of loved ones, and maintaining hobbies can also help patients stay calmer and more connected to reality.
Reducing noise levels in the late afternoon or early evening can aid in the transition to sleep and minimise agitation. Additionally, ensuring patients get enough sunlight during the day and providing consistent daily exercise can improve mood and reduce symptoms of sundowning. Creating a consistent daily routine and sleep schedule can also reduce confusion and agitation. Hospitals should also ensure that doctors and nurses are aware of patients' normal behaviour to help recognise sudden changes and address them promptly.
While medications can be used to treat sundowning and delirium, they should be approached with caution due to potential long-term risks. Instead, environmental changes, such as adjusting lighting and noise levels, can be effective in managing symptoms. Overall, hospitals play a crucial role in preventing and managing sundowning and delirium in elderly patients by implementing these strategies and providing person-centred care.
