A new study published in Annals of Neurology, one of the ANA's two peer-reviewed journals, shows that there is a high frequency of tics in an extremely highly achieving group of pre-pubertal singers. 35% of 40 young singers in the Boys Choir exhibited tics during a public concert of Bach's Christmas Oratorio.
The findings illustrate that there may be a relation between ticcing and professionally engaging in music. The sole perception of tics as a disorder may therefore fall short, particularly in the context of the developing (and performing) brain.
