This is written primarily for clinitians/psychiatrists and possibly social workers and similar professionals. I am neither, I wanted to read this to help me as a 'carer' for a relative. It is full on and I admit I didn't understand every bit of terminology but got the gist and learnt as I went along. I have studied Biological Psychology and psychology myself before, so was familiar with some of the sciency and brain exploration/neuroscience type topics. It was very readable, and I read all 240 something pages in a week on holiday! Some things I'm re-reading especially to try and distinguish the difference between paranoid schizophiernia, paraphrenia and delusional disorder/paranoia. But the moral of the story is that nothing is black and white, as a carer this is hard to take in but then as someone who likes facts and science at least I know where we stand. It's unpredictable, but the more educated I am the more self assured and calm I can remain in supporting the ill relative, and my confidence will make my relative more calm which can only be a good thing. Reading this book made me realise how serious delusional disorders are and all the different types and subtypes and how they are different from schizophrenia (main difference surrounding the effects on personality and prognosis). Basically it tells you how it is, psychotic and other mental health illnesses can be given treatment, the challenge is getting the patient to agree to accept it and maintain where necessary. But I feel that I owe it to my relative to persuade to trust me that I'm trying to help and go along with seeing the doctor in good faith for me, because patience and encouragement is the only way. Ridiculing, ultimatums and anger will do the oposite especially in persecutory subtype delusions because someone with this condition will NOT be convinced that they are wrong but at least can be convinced to accept some help if I can gain trust. Well that's what I'm hoping anyway. Reading this made me thing that if such an illness ever happened to me...would I want someone to try and persuade me to get help to take me out of the tourment? The answer is yes. I wonder if there is a more recent follow up to this book? The more I can learn the more empowered I feel to help, as psychiatrists (for whom this book is written) have not and may not ever get anywhere near my relative....not even the GP.
