b | Data were drawn from the Adelphi HD Specific Programme (DSPTM) conducted between July and October 2017. The DSPTM was a large, point-in-time survey of physicians and their patients in a real-world clinical setting and included 144 neurologists and 427 of their patients with HD in the United States. Physicians were instructed to complete a record form for their patients with HD, either retrospectively from their recent records or prospectively from their next consult.6 |
c | Activities that were not significantly different between patients with chorea and patients without chorea included communication with others, getting in and out of bed, going to the toilet, and gardening.6 |
