It is characterized by an absence of voluntary motion without any apparent motor deficit, and patients often describe a complete mental void or blank. This is accompanied by reduced affect or emotional concern (athymhormy) and often by compulsions, repetitive actions, or tics. After stimulation from the outside, such as a direct command, the patient is able to move normally and carry out complex physical and mental tasks for as long as they are prompted to continue. The symptoms may be differentiated from depression because depression requires the existence of sadness or negative thoughts, while<unk>  patients claim to have complete lack of thoughts, positive or negative.
