    Mean behavior associated with anger can be one of the symptoms of dementia. Those moments can appear suddenly, without an apparent reason, or as a result of frustration. Frustrating situations include experiencing the loss of an ability they previously had by failing a task, for example. Is it important to note, though, that and agressive behavior alone does not mean a dementia diagnosis.
