BACKGROUND: Disturbed gait and balance are among the most consistent sequelae of chronic alcoholism. However, although a majority of alcoholics have never sought treatment, most investigations showing ataxia in alcohol-dependent individuals have relied on samples drawn from treated populations. In addition, few studies have addressed the associations of codependence on other drugs with alcoholic gait and balance disturbance.
METHODS: This study employed the Walk-a-Line Ataxia Battery (Fregly et al. Alcohol Clin Exp Res 1972;43:395-399) to assess gait and balance in treatment-naïve, actively drinking alcohol-dependent men and women (TNA; n = 69) who were dependent on alcohol only (ALC; n = 43), or who also had a lifetime drug dependence (ALC + DRG; n = 26; i.e., methamphetamine, cocaine, opiates, and/or marijuana), compared with nonsubstance abusing controls (NSAC; n = 74).We also examined associations between lifetime alcohol use and age with gait and balance measures.
RESULTS: Our main findings were (i) no evidence of disturbed gait and balance in ALC versus NSAC and (ii) significantly disturbed gait and balance in ALC + DRG, relative to both NSAC and ALC, along with steeper age-associated decline in gait and balance performance in ALC versus ALC + DRG.
CONCLUSIONS: Our results provide evidence consistent with previous studies that TNA (without a lifetime drug codependence) may represent a population that is different and less impaired (including in gait and balance) than treated alcoholics. Additionally, we provide evidence that ALC + DRG, with greater alcohol use and family drinking density than ALC, have an accelerated effect of age on gait and balance disturbance compared with both NSAC and ALC. The ALC + DRG group likely represents a subset of TNA with different characteristics than ALC.
