Understanding Why a Person with Dementia Closes Their Eyes
For caregivers, observing a loved one with dementia keep their eyes closed for extended periods can be confusing and distressing. This behavior is typically associated with the later or advanced stages of dementia but is not necessarily an immediate sign of impending death. Rather, it is a complex symptom that arises from the progressive changes in the brain and a person's diminished capacity to interact with their surroundings.
Overwhelming Sensory Stimulation
One of the most common reasons a person with advanced dementia keeps their eyes closed is to cope with an overabundance of visual and auditory stimuli. A typical environment can be overwhelming for a brain that can no longer process information efficiently. Just as an uncomfortably loud room might cause someone to cover their ears, a person with advanced dementia might close their eyes to block out visual noise. This helps them manage their surroundings and can even aid in concentrating on a different task, like speaking or eating.
Increased Fatigue and Decreased Responsiveness
As dementia progresses, fatigue becomes a significant factor. The brain is working harder to perform even basic functions, leading to increased tiredness. In the late stages, individuals often sleep for much longer periods, and it can become difficult to distinguish between resting, sleeping, and quiet contemplation with eyes closed. A person who is awake but with eyes closed may not respond when spoken to, which can understandably cause concern among family members.
Changes in Visual Processing
The deterioration of brain cells in advanced dementia can affect the complex neural pathways that control vision. This can lead to a condition where the brain struggles to coordinate eye movements or process visual input correctly. In some cases, the effort required to keep the eyes open and process visual information can be too much for the brain. For some, keeping their eyes closed is a neurological response to vision changes that make visual input unpleasant or confusing.
Comparison: Eyes Closed as a Coping Mechanism vs. End of Life Symptom
| Feature | Eyes Closed as a Coping Mechanism (Advanced Stage) | Eyes Closed as an End of Life Symptom (Final Stage) |
|---|---|---|
| Responsiveness | May still respond to gentle touch or a calm voice, though with some delay. Can be roused with effort and may open their eyes intermittently. | Responsiveness significantly decreases. The individual becomes less reactive to external stimuli and may not be rousable. |
| Consciousness | Often happens while awake, as a way to focus or reduce stimulation. The person may be in a state of quiet contemplation or confusion. | Frequently occurs as a part of increased sleeping or loss of consciousness in the days or hours leading up to death. |
| Behavior | May be accompanied by other behaviors such as withdrawing from social interaction or becoming fixated on memories from the past. | Accompanied by other physical signs, such as changes in breathing patterns, mottled skin, and loss of ability to swallow. |
| Cause | Primarily a neurological and psychological strategy to manage overwhelming sensory input. | Part of the body's overall systemic shutdown as it enters the dying process. |
| Duration | Can occur in extended, but intermittent, periods. May happen for hours at a time, but normal wake-sleep cycles still somewhat present. | Characterized by a significant shift in sleep patterns toward increased, sustained periods of sleep and eventual loss of consciousness. |
How Caregivers Can Respond to Eyes Closed Behavior
When your loved one is spending more time with their eyes closed, your approach to care should adapt to their changing needs. Your goal is to provide comfort and connection in ways that don't overwhelm them.
- Reduce sensory overload: Create a calm environment with soft lighting and minimal background noise. This can prevent overstimulation and make the space more comfortable.
- Maintain connection through touch and voice: Since verbal communication may be limited, gentle physical touch can be very reassuring. Hold their hand, place a hand on their arm, or offer a soothing hand massage. Speak to them in a calm, reassuring voice, even if they don't open their eyes. They can still hear you.
- Use non-visual engagement: Focus on other senses. Play their favorite music or audiobooks, which can evoke positive memories. Offer them a familiar blanket with a comforting texture or a warm drink.
- Avoid abrupt movements or loud sounds: Approach slowly and announce your presence with a calm voice before touching them. This prevents startling them, which can be unsettling.
- Monitor for other symptoms: If the behavior is accompanied by a significant decrease in eating and drinking, loss of consciousness, or changes in breathing, it may indicate a transition to the end-of-life stage. Contact their doctor or hospice care team if you observe these signs.
Conclusion
The behavior of a person with dementia keeping their eyes closed is a significant sign of advanced disease progression. It is most often seen in the later stages and can serve as a coping mechanism against overstimulation, a result of cognitive and visual processing decline, or a symptom of the body preparing for its final rest. Caregivers should adapt by creating a calm environment and maintaining connection through gentle touch and soothing verbal communication. Understanding this behavior is crucial for providing compassionate and appropriate care as a loved one navigates the end stages of their journey with dementia. It is always wise to consult with a healthcare professional to rule out any other medical issues and to discuss end-of-life planning.
