What comes to mind when you think of baking homemade bread, or hugging a family member, or climbing the tree outside your childhood home? These memories often come with a smell that help bring that memory into focus.

Those with memory loss diseases such as Alzheimer's Disease and Dementia often demonstrate a difficulty in recognizing scents in addition to their memory loss symptoms. The connection between the olfactory system and the hippocampus, where degeneration due to the disease occurs, is being explored. The aim is to be able to provide a biomarker for diagnosis and a therapy to train the brain towards better scent recognition.
