Sleep deprivation linked to increase in Alzheimer's protein

The video discusses the buildup of beta-amyloid proteins in the brain, which form plaques. It highlights the role of sleep in flushing these proteins from the brain, suggesting that lack of sleep may increase the risk of neurodegenerative diseases. A study by the National Institutes of Health measured amyloid levels in healthy subjects after a full night's sleep and found significant increases in beta-amyloid levels when subjects were sleep-deprived for over 24 hours.

What do beta-amyloid proteins form in the brain?

• Neurons

• Plaques

• Synapses

• Neurotransmitters

How is sleep related to amyloid levels in the brain?

• Sleep decreases the production of amyloids

• Sleep helps in flushing out amyloids

• Sleep has no effect on amyloid levels

• Sleep increases amyloid levels

What is the risk associated with lack of sleep?

• Higher risk of respiratory diseases

• Increased risk of cardiovascular diseases

• Increased risk of diabetes

• Higher risk of neurodegenerative diseases

What was the main finding of the NIH study on sleep deprivation?

• Sleep deprivation has no effect on beta-amyloid levels

• Beta-amyloid levels increase significantly with sleep deprivation

• Beta-amyloid levels remain unchanged with sleep deprivation

• Sleep deprivation decreases beta-amyloid levels

How long were subjects deprived of sleep in the NIH study?

• 24 hours

• 12 hours

• 18 hours

• More than 24 hours
