There are normal changes in the sensory systems; vision, hearing and olfaction, with advancing age.  However, these same systems have changes with neurodegenerative disease that are not considered normal aging.  Diseases such as Alzheimer's and Parkinson's diseases can have sensory system changes that impact function and quality of life.  Further there can be short term dysfunction with vision, hearing and olfaction with acute, recent marijuana use.  The understanding of the cannabinoid system allows us to better understand aspects of neuroprocessing.  Recognizing sensory dysfunction that is not within the continuum of normal aging can result in earlier treatments and interventions.   More recently there has been recognition that the residual effects of COVID may also cause sensory dysfunctions that persist.   This lecture will discuss the current body of knowledge regarding sensory impairment, aging and disease with the emphasis on olfaction.
