COBAS RODRIGUEZ, Manuel Iván; ANIAS CALDERON, José Manuel; CHAO GONZALEZ, Susana  and  VILLAR OLIVERA, Caridad. Yawn as a sign in Parkinson's disease . Rev Cubana Invest Bioméd [online]. 2007, vol.26, n.4, pp. 0-0. ISSN 1561-3011.

The yawns produced by 30 sound individuals and 30 subjects with Parkinson's disease were computed in order to evidence the usefulness they may have as a sign for the evaluation of these patients. The yawns were induced by video for 30 minutes, according to the authors' methods. On comparing the sound subjects with the patients deprived from drugs during 12 hours, it was observed in the latter a significant reduction in the frequency of appearance of yawns (sound 15.086-Parkinson 1.700). On comparing the groups of patients at 2 moments: suspended medication and 1 ½ hour after re-establishing the treatment, it was observed a marked rise of the yawns in the medicated patients (without 1.700-with L-dopa 7.093). From these results, it was inferred that the observation of this behaviour may explain the effects of the treatment being used.

Keywords : Yawn; Parkinson.
