Author response: Clinical outcomes of asleep vs awake deep brain stimulation for Parkinson disease.

We thank Dr. Troster for the thoughtful comments on our article.1 To clarify, Controlled Oral Word Association Test (COWAT) scores were standard scores instead of raw word counts, reflected in the means and SDs pre and post deep brain stimulation (DBS) for categorical fluency (awake pre-DBS: 47.95 ± 7.28, awake post-DBS: 42.94 ± 10.45; asleep pre-DBS: 97.61 ± 17.1, asleep post-DBS: 96.95 ± 15.5) and phonemic fluency (awake pre-DBS: 47.95 ± 7.28, awake post-DBS: 42.94 ± 10.45; asleep pre-DBS: 97.61 ± 17.1, asleep post-DBS: 96.95 ± 15.5).
