"Late catatonia" is a symptomatic concept with characteristic progressive symptoms: Stage 1 (prodrome and primary depression), Stage 2 (anxiety, irritation), Stage 3 (hallucination, delusion), Stage 4 (catatonia), and the residual stage. "The complete type" which progresses to Stage 4 s...Continue Reading
