The way I understand it is dysphoric mania is youre in a manic episode but it is opposite of the euphoric mania where youd feel really good, hyper, like u can take on the world, racing thoughts/flood of ideas/excessive spending, etc. Dysphoric is feeling high energy but is not a good feeling. Its accompanied by extreme irritation/agression, and the racing thoughts are all negatives. Dysphoric mania is also considered "mixed states" where you feel the ups and downs simultaneously. Now as far as agitated depression goes, it can look like dysphoric mania/mixed states but is not considered part of the bipolar spectrum I think because it does not have the manic/high energy aspect of it.
