Fluctuating Attention
This is one of the more common presentations of cognitive impairment in this disease. It is usually one of the first signs of this disease. Patients have difficulty concentrating on any given task. Other times, they appear to be in a state of altered consciousness or are mind-absent from present happenings in their environment.
While present in this state, they can have snatches of agitation, confusion, or make incoherent sentences.
