The experimental group in this study is the group that received the actual drug, as they are the group that is being tested to see if the drug is effective in treating Alzheimer's disease. The group that received the placebo is the control group, which is used to compare the results of the experimental group to a group that did not receive the drug. The group that showed evidence of an improvement in their memory is not necessarily the experimental group, as it could be either the experimental or control group that showed improvement. The group of patients that was not included in the study is not relevant to determining the experimental group.
