Sensory phenomena are general feelings, urges or bodily sensations. [1] They are present in many conditions including autism spectrum disorders, [2] epilepsy, [3] neuropathy, [4] obsessive–compulsive disorder, [2] pain conditions, [5] [6] tardive syndromes, [7] and tic disorders. [8]
Sensory phenomena are associated with Tourette syndrome and tic disorders, and defined as "uncomfortable feelings or sensations preceding tics that usually are relieved by the movement". [9] The tics of Tourette's are temporarily suppressible and preceded by a premonitory urge [10] which is similar to the need to sneeze or scratch an itch. Individuals describe the need to tic as the buildup of tension in a particular anatomical location, [11] which they may consciously choose to release, or which is released involuntarily. [8] The presence of sensory phenomena differentiates subjects with Tourette syndrome plus obsessive-compulsive disorder (OCD) from subjects with OCD alone, [1] and may be an important measure for grouping patients along the OCD-Tourette's disorder spectrum.
