The aim of this chapter has been to provide an understanding of what disorders look like and how they progress, and common suggestions as to possible causes. You have read about some of the diagnosed psychological disorders – schizophrenia, mood disorders, anxiety and personality disorder. They by no means offer an exhaustive insight into all the disorders.
It should hopefully have become clear that there is still a lot to research about most, if not all, disorders. As more becomes known, it will bring with it changes to the assessment, diagnosis and treatment of psychological disorders. The expectation is that not only will current disorders become better understood, but that new ones may be unearthed and others may disappear completely.
