If you are interested in learning more about aphasia and the impact it has on individuals with aphasia, and their circle of family and friends, you should check out Aphasia the Movie, which tells the story of one man's recovery following his stroke.
In this film, Carl McIntyre (an actor and producer; http://www.imdb.com/name/nm0570724/) plays the role of himself and shares through film his experience with stroke, aphasia, and the long road of recovery. One minute, this short film will have you in tears, the next minute, you will be laughing. Or you may also craugh (cry + laugh) as I do every time I watch it (JDRichSLP).
Watch the trailer here. I have purchased the film for outreach, clinical education, caregiver education, and so on, and it was definitely a worthy investment.
