We recently had a few queries around how to reference a podcast. The first question to ask yourself is this a reliable source and good enough for your needs. If you are happy it is and want to include in your assignment then here is how you would reference in the APA 6th style.
So in practice it would look like this in the reference list:
Cohen, S. (Speaker). (2015, September 29). Alzheimer’s is not normal aging and we can cure it [Audio podcast]. Retrieved from https://itunes.apple.com
(Note that the URL is the homepage URL where you found the podcast)
