Chorea could be defined as a state of excessive, spontaneous movements, irregularly timed, randomly distributed and abrupt. Dyskinesias

are accentuated by stress, physical and mental effort or voluntary movements and attenuated by mental relaxation and usually

disappear in sleep. Choreiform dyskinesias originate in striatal dysfunction. Clinical signs typical for chorea are: tongue protrusion sign

(patient can not hold still the protruded tongue, moves the tongue around and back to the mouth), milkmaid grip or grasp sign (during

manual grip the patient involuntary relaxes and gripes the hand as if he would „munch” physicians hand) and dance-like gait with rocking

hip movements denominated the disorder. Classification of choreatic syndromes is very complex and extensive.
