Final answer:
In both Alzheimer's Disease and Creutzfeldt-Jakob Disease, misfolded proteins (prions) are thought to be responsible for the disease.
Step-by-step explanation:
True
In both Alzheimer's Disease and Creutzfeldt-Jakob Disease, misfolded proteins, known as prions, are thought to be responsible for the disease. These misfolded prion proteins can cause normal proteins to misfold, leading to the accumulation of abnormal plaques in the brain and ultimately causing neurodegeneration. This is similar to the role of prions in diseases like Mad Cow Disease.
