This is an interactive workshop style session. Based on a case discussion, students conceptualize the common clinical presentations onto a Venn diagram. The facilitator will take on the role of a family member and nurse, and students have the opportunity to practice obtaining a history that elicits distinguishing features, associated symptoms and time course for each of these cognitive disorders. Emphasizes the importance of getting the history from the family and interdisciplinary team. A Table of Distinguishing Features is completed by the end of the session. An assessment and plan that includes non-pharmacologic and pharmacologic interventions is elicited from the students. The session ends by asking students how they will communicate the plan of care to the family, thus emphasizing the importance of clear communication as a part of the intervention.

Educational objectives: 

1. To review the definitions of Dementia, Depression, and Delerium

2. To identify in what ways these cognitive disorders are similar (common clinical presentations)

3. To list which features help define or distinguish Dementia, Depression, or Delerium

4. To practice the approach to history taking that elicits these distinguishing features

5. To understand that communication with families is an important part of the intervention

Additional information/Special implementation requirements or guidelines: 

A blackboard/ flipchart will be required. Each student should also have a copy of the "Distinguishing Features" table, and a pen.

A concise way of summarizing the 3 D's. I plan to incorporate this information into the "3 D Card Sorting Activity" which I found on POGOe several years ago.
