Final answer:
To develop a drug for Alzheimer's disease, it would make sense to design a drug that stops proteins from misfolding, stops misfolded proteins from aggregating, and stops aggregated proteins from killing neurons.
Step-by-step explanation:
To develop a drug for Alzheimer's disease, it would make sense to take all of the above courses of action: a) Design a drug that stops proteins from misfolding, b) Design a drug that stops misfolded proteins from aggregating, and c) Design a drug that stops aggregated proteins from killing neurons. Proteins misfolding and aggregating into toxic forms are key factors in the development of diseases like Alzheimer's. By targeting these processes, potential treatments can be developed to prevent or alleviate the symptoms associated with the disease.
