'Real Housewives' star Yolanda Foster 'lost the ability to read, write, or even watch TV' after Lyme disease diagnosis

In 2012, Yolanda Foster -- one of the stars of "The Real Housewives of Beverly Hills" -- tweeted that she was having a treatment port implanted, following a diagnosis of Lyme disease.A year later, she was still undergoing procedures related to that diagnosis, as the port was removed in April 2013. Late last week, however, Foster again updated viewers on her condition, writing in a blog post that she continues to suffer, years after symptoms from the disease first began to surface.
