Echopraxia is a typical symptom of Tourette syndrome but causes are not well elucidated. [1]Frontal lobe animation. One theoretical cause subject to ongoing debate surrounds the role of the mirror neuron system (MNS), a group of neurons in the inferior frontal gyrus (F5 region) of the brain that may influence imitative behaviors, [1] but no widely accepted neural or computational models have ...
Older adults tend to see the intrusive thought more as a cognitive failure rather than a moral failure in opposition to young adults. [38] They have a harder time suppressing the intrusive thoughts than young adults causing them to experience higher stress levels when dealing with these thoughts.
Immediately preceding tic onset, most individuals with Tourette syndrome are aware of an urge, [6] which is similar to the need to sneeze or scratch an itch.
