Mania symptoms suddenly appear and can last for weeks or months. In the early stages of mania, the individual feels better than usual and seems more cheerful, rejuvenated and more energetic, may present false beliefs of personal wealth, power, inventiveness and genius, and may temporarily assume a grandiose identity, sometimes believing be God. Your need for sleep decreases and the patient sleeps less.
During a crisis of mania, the patient can either believe that he is being helped or persecuted by other people as he may hallucinate, hearing and seeing things that do not exist.
The individual with mania does not perceive his condition and therefore added to his increased capacity for activities, he becomes impatient, inadequate, intrusive and irritable and generally prone to aggression.
