Excessive Sleepiness in Elderly: Causes and Solutions

Elderly individuals experiencing excessive sleepiness?

Dear Dr.
Ouyang,
My father is 78 years old and recently, possibly due to the cold weather or other reasons, he has been frequently sleeping deeply and not waking up, missing both breakfast and lunch.
He has previously been evaluated at a geriatric clinic, where the physician suggested that he shows symptoms of dementia.
I would like to know if this could be related to his excessive sleepiness.
How should I address this issue (regarding diet, exercise, etc.)?
In November 2003, he was hospitalized for a month due to a fracture in his left thigh.
Although he has recovered, he has not been diligent with rehabilitation exercises, which has resulted in ongoing mobility issues.
Additionally, he does not have a proactive mindset.

Thank you for taking the time to respond.
Best regards,
Zhu Jie

Hello, Liu Zu-Jie.
It is true that a significant proportion of individuals with dementia (currently referred to as cognitive impairment) experience sleep issues, including insomnia, hypersomnia, and problems with circadian rhythms.
Your father’s hypersomnia may require further investigation to determine the underlying causes, such as irregular eating patterns or reduced food intake leading to nutritional deficiencies (like Vitamin B12 and folate), or other health conditions such as electrolyte imbalances or liver and kidney function issues.
If these conditions can be ruled out after testing, you might consider establishing a fixed schedule to wake him up and encourage participation in daytime activities, such as walking, socializing with neighbors, or engaging in daytime programs at institutions like the New Taipei City Hospital, the Chiayi County Health Bureau’s Chianan Nursing Home, or nearby facilities.
It is crucial to prioritize rehabilitation activities during the day.
Regarding the aspect of "lack of motivation," it is possible that dementia patients may exhibit lower motivation (avolition), reduced physical strength, or symptoms of depression, all of which can contribute to a less proactive mindset.
Additionally, any issues with hearing, vision, or communication, including aphasia, may hinder the patient's understanding and willingness to engage.

More Info

Excessive sleepiness in the elderly can be a complex issue, often influenced by a variety of factors including medical conditions, lifestyle choices, and psychological well-being. In your father's case, at 78 years old, his frequent episodes of excessive sleep and difficulty waking up could indeed be related to underlying health issues, including the possibility of dementia, as suggested by his previous evaluations.

Understanding Excessive Sleepiness
1. Medical Conditions: Conditions such as dementia can significantly impact sleep patterns. Individuals with dementia may experience changes in their circadian rhythms, leading to increased daytime sleepiness and disrupted nighttime sleep. Other medical conditions, such as sleep apnea, depression, or chronic illnesses, can also contribute to excessive sleepiness.

2. Medication Side Effects: If your father is on medication for any chronic conditions, it’s important to review these with his healthcare provider. Some medications can cause sedation or fatigue as side effects, which may exacerbate his sleepiness.

3. Nutritional Factors: Poor nutrition can lead to deficiencies in essential vitamins and minerals, which can affect energy levels. For instance, deficiencies in Vitamin B12 and folate can lead to fatigue and cognitive decline. Ensuring a balanced diet rich in fruits, vegetables, whole grains, and lean proteins is crucial for maintaining energy levels.

4. Physical Activity: Regular physical activity is vital for older adults. It can help improve mood, increase energy levels, and promote better sleep quality. Since your father has been less active due to his previous injury, encouraging gentle exercises, such as walking or stretching, can be beneficial. Engaging in physical therapy or rehabilitation programs may also help him regain strength and mobility.

5. Psychological Factors: A lack of motivation or a negative mindset can contribute to excessive sleepiness. This could be linked to depression, which is common in older adults, particularly those with chronic health issues. Encouraging social interactions, hobbies, and activities he enjoys can help improve his mood and overall outlook.

Recommendations for Management
1. Routine and Structure: Establishing a daily routine can help regulate his sleep-wake cycle. Encourage him to wake up at the same time each day and to engage in activities during the day to promote alertness.

2. Limit Daytime Naps: While short naps can be refreshing, long or frequent daytime naps can interfere with nighttime sleep. Encourage him to limit naps to 20-30 minutes if he feels the need to rest during the day.

3. Sleep Environment: Ensure that his sleeping environment is conducive to restful sleep. This includes a comfortable mattress, appropriate room temperature, and minimal noise and light disturbances.

4. Consult Healthcare Providers: Since your father has been evaluated for dementia, it would be beneficial to follow up with his healthcare provider regarding his sleep issues. They may recommend a sleep study or further assessments to rule out conditions like sleep apnea.

5. Encourage Social Engagement: Social activities can help combat feelings of isolation and depression, which can contribute to excessive sleepiness. Encourage him to participate in community activities or family gatherings.

6. Monitor and Adjust Diet: Consider consulting a nutritionist to ensure he is receiving adequate nutrition. Foods rich in omega-3 fatty acids, antioxidants, and vitamins can support brain health and overall energy levels.

In conclusion, while excessive sleepiness in the elderly can be concerning, it is essential to approach it holistically, considering medical, nutritional, psychological, and lifestyle factors. By addressing these areas, you can help improve your father's quality of life and potentially mitigate some of the excessive sleepiness he is experiencing. Regular follow-ups with healthcare professionals will also be crucial in managing his overall health and well-being.
