TED-Ed: Why is Alzheimer’s disease so difficult to treat? | Krishna Sudhir

Alzheimer's is a debilitating brain disorder affecting memory and cognitive abilities, with no cure yet. It accounts for most dementia cases and is caused by complex genetic, lifestyle, and environmental factors. Research focuses on beta amyloid and Tau proteins, but the disease's complexity requires more study. Managing symptoms through activities and medications can help, and ongoing research aims to improve treatments.

What percentage of dementia patients worldwide are affected by Alzheimer's disease?

• 60 to 80%

• 40 to 50%

• 20 to 30%

• 90 to 100%

Which protein is associated with the abnormal buildup in Alzheimer's patients?

• Prion

• Synuclein

• Beta amyloid

• Tau

What is the normal role of Tau protein in the brain?

• Aiding in neural growth

• Reinforcing neuron structure

• Breaking down neurotransmitters

• Transporting nutrients

Which cells are linked to changes in Alzheimer's disease according to recent studies?

• Ependymal cells

• Oligodendrocytes

• Microglia

• Astrocytes

What lifestyle change can help manage Alzheimer's symptoms?

• Reducing physical activity

• Staying active and learning new skills

• Increasing sugar intake

• Avoiding social interactions

What is the focus of new therapies being developed for Alzheimer's?

• Reducing Tau tangles

• Targeting beta amyloid

• Targeting neurotransmitters

• Increasing synaptic connections

What is the expected trend for dementia cases in the next 20 years?

• They will triple

• They will remain the same

• They will decrease by half

• They will double
