The Inova research team will ask people who have had an experience of breast cancer and related changes to their cognition to complete some scales that researchers have established describe brain fog (called patient reported outcomes) and compare those results to the TOSL results. This will be done twice to see if changes are detected similarly on both types of measures.

Current brain fog research struggles to clearly define and measure brain fog because the changes are more subtle than typically show up on "objective" tests. These subtle changes on the tests, may not appear subtle in everyday life. This disconnect can lead to people managing cancer feeling unheard or unbelieved about their experience with brain fog. However, cognitive research outside of the cancer population has developed and tested tests that are more sensitive to cognitive changes and improvements. The goal of this initial research project is to test a more sensitive test, called the Test of Strategic Learning (TOSL), to see if it is sensitive enough to objectively measure brain fog.

One other problem with previous brain fog research is that it has not included a diverse population. Therefore, what we think we know about brain fog may not be true for everyone with brain fog. The diverse population in the DMV area that Inova serves deserves to have their experiences represented in the research.
