TED: Are brain waves the secret to treating Alzheimer's? | Li-Huei Tsai

The video discusses the role of brain waves, particularly gamma waves, in transmitting information and their potential link to Alzheimer's disease. Research shows that weakened gamma waves may contribute to Alzheimer's. Studies at MIT found that stimulating gamma waves with light and sound can improve brain function in mice and potentially humans. Initial human trials show promising results, suggesting gamma wave stimulation could delay Alzheimer's onset. The approach is noninvasive and safe, offering hope for future treatments.

What is the primary role of brain waves according to the introduction?

• To regulate body temperature

• To control muscle movements

• To transmit information and thoughts

• To generate energy for the brain

How are gamma waves linked to Alzheimer's disease?

• They are completely unrelated

• They only affect young people

• They cure Alzheimer's disease

• Weakened gamma waves may contribute to the disease

What was the hypothesis tested in 2015 regarding gamma waves?

• Gamma waves can improve eyesight

• Artificially boosting gamma waves might affect Alzheimer's

• Gamma waves are irrelevant to brain function

• Gamma waves can be used to treat heart disease

What method was used to increase gamma waves in mice?

• Administering medication

• Increasing physical activity

• Using light and sound stimulation

• Providing a special diet

What were the observed benefits of gamma wave stimulation in mice?

• Improved vision

• Decreased appetite

• Reduced protein buildups and improved memory

• Increased aggression

What device was developed for human studies on gamma wave stimulation?

• A light and sound stimulation box

• A wearable wristband

• A virtual reality headset

• A smartphone app

What initial results were observed in human studies?

• No change in brain activity

• Increased connectivity and synchrony in the brain

• Decreased cognitive function

• Increased physical strength

What is the potential benefit of gamma wave stimulation in Alzheimer's treatment?

• It can completely cure Alzheimer's

• It may delay the onset of the disease

• It has no effect on Alzheimer's

• It can cause Alzheimer's

What is the vision for the future use of gamma wave stimulation?

• To ban it completely

• To use it only in hospitals

• To integrate it into daily environments

• To replace all medications

What makes gamma wave stimulation a potentially accessible treatment?

• It is very expensive

• It is noninvasive with minimal side effects

• It requires surgery

• It is only available in certain countries
