Symptom 4: Altered Sleep Patterns
Sleep is one of the most affected aspects when delirium sets in. Individuals might find themselves battling insomnia or, at the other end of the spectrum, feeling excessively sleepy during the day. For some, their entire sleep-wake cycle gets reversed, causing them to stay awake at night and sleep during daylight hours.
While sleep disturbances might seem minor compared to other symptoms, they can significantly impact overall health. Consistent lack of sleep or disturbed sleep can exacerbate other symptoms of delirium, leading to a vicious cycle.
But why does delirium impact sleep so drastically? Often, it’s the result of the brain’s impaired ability to regulate sleep. Additionally, other symptoms, like hallucinations or emotional disturbances, can directly affect sleep quality. (4)
