Judge a Book by its Cover: Help, I'm berried in ideas

At the minute I'm feeling quite berried and confused and I'm really struggling to consolidate my ideas as there's so many different contrasting themes running through my book. The preface puts quite a positive spin on neurological disease. It talks about how disease can destroy neurological paths in the brain, which are then reformed in new ways. This allows the person to think differently to the average person, leading to increased creativity and evolution.

However, all of the case studies in the book have quite a negative feel to them. The first talks about a painter who becomes colour blind. What he sees is described as a 'black and white TV screen' yet he is surrounded by a world of colour. This is reflected in the current book cover. The second case study is abut a monk who is seeking solace with an undetected tumour. It has a similarly sombre feel to it.

The conflicting ways in which neurological disease can effect a person has got me feeling confused. I was going to create quite a positive cover about creativity but I'm now not sure. I could look at how disease effects a person's sense of self and weather it is lost or enhanced. This is a strong theme, which runs through the whole book and sums up what it is about nicely. 

I also could explore dreams as the vividly of the patient's dreams is spoken about across all case studies in addition to the thin line between reality and their own created worlds. I could also look at how this creative enhancement is a positive thing in contrast to the negative way mentally ill people are often looked upon by society. This might be an interesting way to explore colour. 

This blog post has really helped me to consolidate my ideas more and I now want to try and separate them in a mind map before I start woking visually.
