Abstract
To investigate the relationship between substances of abuse and age at motor onset (AMO) in patients with Huntington disease (HD) in a large and diverse patient population.
This was a retrospective, observational study of the Enroll-HD database. Participants were determined to belong to 1 of 3 substance abuse groups: (1) tobacco abusers, (2) alcohol abusers, and (3) drug abusers. A group of participants who had never abused substances served as a control group. The average AMO of patients in the substance abuse groups was compared to the control group. The number of CAG repeats was used as a covariate in all analyses.
The average difference in AMOs of participants in the tobacco (n = 566), alcohol (n = 374), and drug abuse groups (n = 217) compared to the control group (n = 692) were 2.3 (
= 33.8,
< 0.0001), 1.0 (
= 4.2,
= 0.04), and 3.3 (
= 29.7,
< 0.0001) years earlier, respectively. In all substance abuse groups, the AMO was lowered to a greater degree in female participants than it was in male participants.
Substances of abuse have a strong effect on the AMO in patients with HD. These effects seem to be amplified in women with HD compared to men. These results may provide a safe intervention capable of adding disease-free years to patients with HD.
