This is a table from a study entitled "Prodromal symptoms in manic depressive psychosis" by Smith & Tarrier, 1992. (Abstract)
A prodrome is an early symptom that a disease or attack is about to occur - in this case, an early symptom of a mood episode.
I saved this table because I sure can relate to it! Note how some of the symptoms are physical - like feeling tired - while others are changes in thought patterns - like feeling guilty or spending money more freely. The fact that some symptoms represent themselves as thoughts makes it really hard!
I think this table gave me a lot of insight. For more insight, check out "Loving Someone with Bipolar Disorder" by Julie Fast. Although this book is for a family member to read, it is really worth reading if you have bipolar disorder yourself. She talks about the thought patterns that are symptoms as well. Plus she has lots of ideas for possible triggers.
