Pure mania is characterized by euphoria, restless activity, wealth of expressive motions, overtalkativeness, flight of ideas, heightened self-importance, and rapidly changing ideas of grandeur. The excitement does not change into confusion or hyperkinesia. Thus pure mania appears milder than many cases of mania of manic-depressive illness. But more than mania of manic-depression it tends towards a chronic course, at times in the form of hypomania. The accompanying bodily phenomena are similar to those of mania of manic-depressive illness, but the subjective feeling of great bodily strength is more pronounced, whereas overexertion from excitement which could cause bodily harm is absent.
