Lack of sleep could increase the risk of dementia

Do you hit the ‘snooze’ function on your alarm clock multiple times before waking up in the morning? Do you doze off whenever you sit down and get comfortable? What about having difficulty in concentrating or impaired memory? If you answer ‘yes’ to any of these, you may be suffering from sleep deprivation.

Sleep deprivation is associated with many health risks such as depression, heart disease and stroke. In April 2018, a study on the effect of sleep deprivation on the brain showed that continued lack of sleep could lead to a build-up of amyloid beta in the brain – a substance that contributes to the formation of amyloid plaques, which is linked to dementia and Alzheimer’s disease.

How does a lack of sleep increase the risk of dementia?

Just like any other organ or muscle, the brain produces waste products throughout the day that need to be removed, one of them known as amyloid beta. The central nervous system has what is known as the glymphatic system, a series of cell-defined pathways in the brain dedicated to removing these waste products.

Getting a substantial amount of undisturbed sleep is important is because the glymphatic system is not especially effective when we are awake. However, it becomes far more efficient at removing waste products when we are asleep. Without these periods of rest, the glymphatic system cannot remove enough of the amyloid beta in the brain, causing it to slowly build up as amyloid plaques, which hinder communication between neurons, and is known to play a role in Alzheimer’s.

A single poor night of sleep isn’t something to worry about, as the glymphatic system can regulate the amyloid beta levels over time. However, sustained periods of disrupted and poor sleep can add up, causing lasting damage.

How can you reduce your risk of dementia?

Getting enough rest every night could help to reduce your risk of dementia. An adult should receive an average of seven to nine hours of sleep every night. Additionally, we should be having deep, undisturbed REM (Rapid Eye Movement) sleep so that the body can keep the amyloid beta in the brain at a manageable level. It has also been shown that sleeping on your side allows the body to remove waste chemicals from the brain more efficiently. Although, with normal levels of sleep, it’s not something you should go out of your way to accommodate.

Getting more sleep isn’t the only way to reduce dementia. Other tactics include drinking less alcohol and taking part in regular physical and mental exercises.
