Going by the dictionary, to gaslight someone is a strategy to psychologically manipulate them over a period of time so the targeted person questions the validity of their own thoughts and their perception of reality. While gaslighting isn't a formal medical diagnosis, it can have a big impact on our mental health. To help us better understand the term, since it's everywhere these days, Faith is joined this week by Dr. Warren Ng, a psychiatrist at New York Presbyterian and Columbia, and the Community Health Director for New York Presbyterian's Center for Youth Mental Health. He shares how to recognize the signs of gaslighting and offers tips on how to combat it and protect your mental health.
