Previously, an anticholesterol drug was reported by a few patients as potentially alleviating the symptoms of Alzheimer's disease.
Hypothesis: Drug X will alleviate signs of Alzheimer's disease.
Experimental design: Patients with Alzheimer's disease are split into two groups: one group will receive Drug X and the other will receive a placebo (sugar pill).
Patients: 400 patients with Alzheimer's disease were recruited for this study and arbitrarily assigned to a treatment group.
Treatment: Patients were treated for 90 days with either Drug X or placebo.
Study measurements: Patients were assessed using a memory test before and after the treatment period.
Results: Patients given Drug X scored higher on the memory test.
Conclusions: Drug X can enhance memory in patients suffering from Alzheimer's disease.
