All of us have thoughts and daydreams that seem strange to us. Images of violent or bad behavior might seem to pop into our heads, or we may begin to wonder if we are susceptible to germs and contamination. Most of the time, we don’t pay these random mental events much mind. We simply shrug them off and get on with our day. Sometimes though, these images can persist. Like a pop song that gets “stuck in our heads” these disturbing ideas keep coming back, again and again. It can seem that the more we try to force such inappropriate, unpleasant, or even “sinful” ideas out of our consciousness, they only return with greater force. Intrusive thoughts that persist in this way may be symptoms of obsessive-compulsive disorder (OCD). This brief introductory podcast is delivered by Dr. Dennis D. Tirch, Director of Education at AICT.
