Agraphesthesia
Agraphesthesia
Agraphesthesia, dysgraphesthesia, or graphanesthesia, is a loss or impairment of the ability to recognize letters or numbers traced on the skin (i.e., of graphanesthesia). Whether this is a perceptual deficit or a tactile agnosia ("agraphognosia") remains a subject of debate. It occurs with damage to the somatosensory parietal cortex.
