Abstract—Objective: To determine whether motor, behavioral, or psychiatric symptoms in Huntington disease (HD)
predict skilled nursing facility (SNF) placement. Methods: Subjects were participants in the Huntington Study Group’s
Unified Huntington Disease Rating Scale Database (Rochester, NY) between January 1994 and September 1999. Specific
motor, psychiatric, and behavioral variables in subjects residing at home and in SNF were analyzed using
2
and
Student’s t-tests. For a subset of subjects for whom longitudinal data existed, a Cox proportional hazards model control-
ling for age, sex, and disease duration was used. Results: Among 4,809 subjects enrolled, 3,070 had clinically definite HD.
Of these, 228 (7.4%) resided in SNF. The SNF residents’ average age was 52 years, average disease duration was 8.6
years, and they were predominantly women (63%). The SNF residents had worse motor function (chorea, bradykinesia,
gait abnormality, and imbalance, p 0.0001); were more likely to have obsessions, compulsions, delusions, and auditory
hallucinations; and had more aggressive, disruptive (p 0.0001), and irritable behaviors (p 0.0012). For 1,559 subjects,
longitudinal data existed (average length of follow-up, 1.9 years), and 87 (5%) moved from home to SNF. In the Cox model,
bradykinesia (HR 1.965, 95% CI 1.083 to 3.564), impaired gait (HR 3.004, 95% CI 1.353 to 6.668), and impaired tandem
walking (HR 2.546, 95% CI 1.460 to 4.439) were predictive of SNF placement. Conclusions: Institutionalized patients with
HD are more motorically, psychiatrically, and behaviorally impaired than their counterparts living at home. However,
motor variables alone predicted institutionalization. Treatment strategies that delay the progression of motor dysfunction
in HD may postpone the need for institutionalization.

Huntington disease (HD) is a progressive, autosomal
dominant neurodegenerative disease. Dementia, psy-
chiatric symptoms, chorea, and impairment of volun-
tary movement together result in progressive loss of
independence. Unlike the elderly demented popula-
tion residing in skilled nursing facilities (SNF), peo-
ple with HD are younger and have unique care
needs. A 1996 retrospective study described the fea-
tures of 97 people with HD who resided in an HD
specialty unit at a SNF (n 83) or in other SNF (n
14) in Minneapolis–St. Paul between 1976 and
1993.

These residents were typically single, age 45,
of either sex, and high school graduates. One third
had serious behavioral problems, most were treated
with psychotropic drugs, and 84% were still ambula-
tory upon admission.
Little additional information exists about the mo-
tor and psychiatric characteristics of people with HD
who reside in SNF. Because institutionalization is a
highly significant event in the course of HD, identifi-
cation of the predictors of nursing home placement
may engender interventions that postpone this out-
come. Furthermore, characterization of HD-specific
characteristics in SNF residents should optimize
their care. We sought to determine specific motor,
psychiatric, and behavioral characteristics in a large
cohort of people with HD who reside in nursing
homes, and to determine which characteristics pre-
dict institutionalization. We examined motor dys-
function, psychiatric symptoms, and the presence of
aggressive and disruptive behavior or irritability as
possible determinants of SNF placement.
Methods. Subjects. Subjects included those found in the Hun-
tington Study Group’s (HSG) Unified Huntington Disease Rating
Scale (UHDRS) database (Rochester, NY).

Data were obtained
from 43 HSG member sites in North America, Europe, and Aus-
tralia. Subjects had clinically definite HD. Some subjects had ge-
netic confirmation by CAG expansion, but this was not required.
For a subset of subjects follow-up assessments were made about
every 6 months.
Assessment. All subjects were assessed using the UHDRS.
The UHDRS consists of five sections. Demographic data are ob-
tained at the baseline visit; motor, cognitive, behavioral, and func-
