How do you know if someone has it?

To identify sundowner syndrome, it is important to observe whether the following behaviors are systematically repeated in the late afternoon:

  • Sudden change of mood

  • Aggressive or irritable reactions for no apparent reason

  • Greater confusion compared to the rest of the day

  • Restlessness or a tendency to wander aimlessly

  • Difficulty sleeping or insomnia

The temporal evolution of symptoms is essential for diagnosis: they worsen in the evening and generally improve in the morning.

Possible treatments and approaches

There is no specific treatment for sundowner’s syndrome, but there are strategies that help reduce its impact:

  • Structured routine  : Maintaining regular schedules for meals, hygiene, and rest can reduce anxiety.

  • Proper lighting  : Use bright light in the late afternoon to help synchronize the body clock

  • Avoid stimulants  : limit caffeine and sugars late in the day

  • Calming activities  : Listening to soft music, doing light exercise, or reading to relax at the end of the day

  • Drug treatment  : In severe cases, a doctor may prescribe medication for anxiety or insomnia.
