I have realised through a few hours of research that the four subjects outlined in my SWOT analysis' would be unsuitable subjects to undertake for my EPQ. The main reason being that I was mostly invested in doing the one about neurological issues, the main issue I had with that was that the subject was so specific there were only 3 books that I would have been able to use and even then only small parts of the book would have relevant information. Another issue was that 2 of the books would have been roughly £40 each and the third was no longer being published. I shall continue research looking for another subject.
