Unlocking the Power of Deep Sleep: Reducing Dementia / Alzheimer's Disease Risks and Promoting Cognitive Health

 

Ever since my childhood, I have developed a habit of staying up late due to the need to study diligently in order to maintain my scholarship and complete my education. This habit has persisted, and I still struggle to fall asleep early, especially when I'm feeling upset or stressed.

I understand the importance of deep sleep for overall health, as well as its potential role in reducing the risk of dementia or Alzheimer's disease. However, more often than not, I find myself awake and alert at unholy hours of the night.

I don't want to experience memory-related illnesses as I age, and I believe most people share this sentiment. The experiences of my mother-in-law and others who have suffered severe cognitive decline serve as a stark wake-up call.

According to the Guardian,

The biological ‘brainwashing’ that happens while you are sleeping is crucial for filtering out toxins.

While there's no guaranteed method to prevent dementia, there are several practices we can adopt to promote deep, restorative sleep, which may contribute to cognitive health:

1.  Establish a consistent sleep schedule:  Go to bed and wake up at the same time each day, even on weekends. This helps regulate your body's internal clock.

2.  Create a relaxing bedtime routine:  Develop calming activities before bedtime, such as reading a book, taking a warm bath, or practicing relaxation techniques like deep breathing or meditation.

3.  Limit exposure to screens:  Avoid electronic devices like smartphones, tablets, and computers at least an hour before bedtime. The blue light emitted from screens can disrupt your sleep cycle.

4.  Create a comfortable sleep environment:  Ensure your bedroom is cool, dark, and quiet. Invest in a comfortable mattress and pillows. Consider using blackout curtains and white noise machines if needed.

5.  Watch your diet:  Avoid large meals, caffeine, and alcohol close to bedtime, as these can disrupt sleep. Instead, opt for a light snack if necessary.

6.  Stay physically active:  Regular exercise can help improve sleep quality. However, avoid strenuous physical activity close to bedtime. 

7.  Manage stress:  Practice stress-reduction techniques, such as mindfulness meditation or yoga, to calm your mind and promote better sleep.

8.  Limit naps:  While short daytime naps can be refreshing, long or irregular napping during the day can interfere with nighttime sleep.

9. Limit fluid intake before bed:  Minimize your consumption of liquids in the evening to reduce the likelihood of waking up to use the bathroom during the night.

Getting deep, restorative sleep is just one aspect of a healthy lifestyle that may contribute to a reduced risk of dementia. 

Maintaining a balanced diet, staying mentally and socially active, and engaging in regular physical activity are also essential for overall brain health.

How does a deep sleep help reduce the risk of Alzheimer's disease?

1.  Clearance of amyloid beta:  During deep sleep, the glymphatic system becomes more active. This system acts as a "cleaning crew" for the brain, helping to clear away waste products like amyloid beta, a protein that forms plaques in the brains of Alzheimer's patients. Adequate deep sleep is essential for this clearance process to occur efficiently.

2.  Memory consolidation:  Deep sleep is closely linked to memory consolidation. During this phase, the brain processes and stores information from the day, which is essential for learning and cognitive function. A lack of deep sleep can impair memory, which is a common early symptom of Alzheimer's

3.  Neuroprotection:  Deep sleep promotes neuroprotection by supporting the repair and maintenance of brain cells. It allows the brain to recover from daily stressors and helps prevent the loss of neurons, which is a hallmark of Alzheimer's disease.

4.  Reduced inflammation:  Quality sleep, including deep sleep, is associated with lower levels of inflammation in the body. Chronic inflammation is a known risk factor for Alzheimer's and other neurodegenerative diseases.

5.  Hormone regulation:  Deep sleep helps regulate hormones, including those related to stress and appetite. Chronic stress and weight-related issues are linked to a higher risk of Alzheimer's disease.

6.  Enhanced cognitive function:  Deep sleep is vital for cognitive function and problem-solving skills. Individuals who consistently experience restorative sleep tend to have better cognitive abilities, which may help them maintain mental acuity as they age.

7.  Emotional well-being:  Adequate deep sleep is crucial for emotional well-being and the regulation of mood. Chronic sleep disturbances can lead to depression and anxiety, which are linked to cognitive decline and an increased risk of Alzheimer's.

It's important to note that while deep sleep is essential for brain health and may help reduce the risk of Alzheimer's, it's just one piece of the puzzle.

DIFFERENCES BETWEEN DEMENTIA AND ALZHEIMER'S DISEASE

Dementia and Alzheimer's disease are related but distinct conditions. Here are the key differences between them:

Dementia:

Definition: Dementia is an umbrella term that describes a range of cognitive impairments and symptoms that interfere with a person's daily life and functioning. It is not a specific disease but a syndrome characterized by cognitive decline.

Causes: Dementia can be caused by various underlying conditions, including Alzheimer's disease, vascular dementia, Lewy body dementia, frontotemporal dementia, and others. Each type of dementia has distinct causes and characteristics.

Progression: The progression of dementia depends on the underlying cause. Different types of dementia may progress at varying rates and have unique symptom profiles.

Symptoms: Common symptoms of dementia include memory loss, confusion, difficulty with communication, impaired reasoning and judgment, and changes in behavior and personality.

Treatment: Treatment for dementia involves managing its underlying cause, when possible. This may include medications, lifestyle changes, and supportive therapies to alleviate symptoms and improve quality of life.

Alzheimer's Disease:

Definition: Alzheimer's disease is the most common cause of dementia, accounting for the majority of dementia cases. It is a specific and progressive brain disorder.

Causes: The primary cause of Alzheimer's disease is the accumulation of abnormal protein deposits in the brain, including beta-amyloid plaques and tau tangles. These deposits lead to the death of brain cells and the gradual deterioration of cognitive function.

Progression: Alzheimer's disease typically progresses in stages, starting with mild memory impairment and eventually leading to severe cognitive and functional decline.

Symptoms: Common symptoms of Alzheimer's disease include memory loss, disorientation, difficulty with language and communication, challenges with problem-solving, and personality changes. As the disease advances, individuals may experience difficulty with basic tasks like dressing and eating.

Treatment: While there is no cure for Alzheimer's disease, there are medications that can temporarily alleviate some of the symptoms and slow down cognitive decline. Treatment also includes supportive care, lifestyle modifications, and assistance with daily activities.

In summary, dementia is a broad term encompassing various cognitive disorders, while Alzheimer's disease is a specific and common type of dementia with a well-defined pathological basis. 

Alzheimer's disease is one of the many possible causes of dementia, but not all cases of dementia are attributed to Alzheimer's. The choice of treatment and management strategies depends on the underlying cause of dementia in each individual case.

I will try my best to passionately maintain a healthy lifestyle, engage in cognitive and social activities, avoid foods and beverages that will lead to chronic conditions (although at the moment I suffer from hypertension) and stay mentally and physically active.  These all are but a holistic approach to prevention of memory-related illnesses.

Note: Now that you know the power of deep sleep, you know what to do. If you have concerns about memory-related health issues or sleep disturbances, it's advisable to consult with a healthcare professional for personalized guidance and evaluation. They can help identify any underlying issues like sleep apnea or insomnia and recommend appropriate treatments.

"Wasting of Women's Talents Must Cease"

Here I am in a four-cornered room, thinking of many things that I can do considering my talents, but I cannot utilize to the fullest due to some obstacles which are not just in the mind but real. I am woman -- I know I have a power inside me yet I feel vulnerable. There is an interesting article published in Gulf News, "In the Middle East, Momentum for Women Must Pick Up Speed" written by Shaikh Abdullah Bin Zayed Al Nahyan, dated 31 May 2018. Very timely, indeed, that I saw this article few minutes back. I am inspired to read similar write-ups promoting advocacy on importance of empowering women by giving them solid support. Can we quantify wasted women's talents? Maybe we can in terms of lost opportunities. Or can we enumerate wasted women's talents if we cannot quantify them? There are women who are full-time mothers and housewives, either by choice or by tradition or both. We know that being so is indeed a tiring unpaid job for many women. For some they ...

Of Ginger-Lemon Water, and A/C Off

  And so I am now again drinking a lot of hot lemon tea with ginger. It will help improve my health immunity .  WebMD.com says, " Lemon is a rich source of vitamin C and antioxidants, which both have immunity-boosting properties. Ginger also has immunity-boosting properties and can guard against some bacteria." Am coughing when my back is sweating. The air conditioner is switched off again. If you are in the Gulf area, even if it is December it is still hot. There are times when it is even hotter inside my partitioned room with a window facing the sun, no building near ours to block the scorching heat -- than the actual temperature outside. I have a temperature app in my mobile phone and I regularly check it. When I switch on the air conditioner, somebody else switches it off. (I remember when we transferred to the our previous flat and I was told that the A/C was centralized, 24/7 on. I was grateful because the heat of human bodies, the lights, their gadgets -- laptops and m...

'Hotelcation' and More

My youngest daughter surprised me with the good news that she was allowed to go on Eid vacation for some days. She badly needed rest and relaxation for a work-life balance. It was very hot here in the UAE when we got blissfully reunited at 2 PM.  It was Eid so most hotels nearby were either fully booked, or if not, their room rate boards showed AED800/day +/-. My frugal daughter stepped back when she saw 'towering' figures. A I watched my Buninay eating halohalo in our meeting place, a restaurant serving Filipino foods, I held my tears back. She ordered 'mixed-with-everything' fried rice, grilled squid and  kinilaw  (raw fish with vinegar, chili and chopped onions).  Memories of her childhood flooded in my mind. How time flies! My then-baby-who-is-now-a-lady wanted to spoil me. Felt truly blessed beyond words. We hopped to Seattle's Best in the mall near the mosque. While indulging myself with my favorite Cinnabon bites and strawberry smoothies, and my ol...
