Alzheimer's starts in people as young as 20, much earlier than previously thought

The video discusses the presence of amyloid plaques in young individuals and the role of abnormal Tau protein in causing neurofibrillary tangles in the brain. It highlights research efforts at Harvard and the University of San Luis Potosi to detect Tau protein levels through brain scans and skin biopsies, respectively.

What is the role of Tau protein in the brain?

• It prevents neurofibrillary tangles.

• It enhances neuronal communication.

• It forms amyloid plaques.

• It supports the structure of microtubules.

What happens when microtubules collapse in the brain?

• Neuronal endings are strengthened.

• Fibers twist together forming tangles.

• Amyloid plaques are dissolved.

• Tau protein levels decrease.

What are neurofibrillary tangles?

• Regions of increased neuronal activity.

• Clusters of healthy neurons.

• Twisted fibers resulting from microtubule collapse.

• Deposits of amyloid plaques.

What is the focus of the research conducted at Harvard?

• Analyzing the genetic basis of neurodegeneration.

• Developing new medications for Alzheimer's.

• Scanning brains for higher levels of Tau protein.

• Studying the effects of diet on brain health.

How do researchers at the University of San Luis Potosi propose to detect Tau protein levels?

• Using skin biopsies.

• Through blood tests.

• Via spinal fluid analysis.

• By monitoring cognitive tests.
