The impact of neurological disorders on the risk for falls in the community dwelling elderly: a case-controlled study

Owing to a lack of data, our aim was to evaluate and compare the impact of various common neurological diseases on the risk for falls in independent community dwelling senior citizens.

Prospective case-controlled study.

General hospital.

Of 298 consecutive patients and 214 controls enrolled, 228 patients (aged 74.5±7.8; 61% women) and 193 controls (aged 71.4±6.8; 63% women) were included. The exclusion criteria were as follows: for patients, severe disability, disabling general condition or severe cognitive impairment; for controls, any history of neurological disorders or disabling medical conditions; and for both, age below 60 years. A matching process led to 171 age-matched and gender-matched pairs of neurological patients and healthy controls.

A 1-year incidence of falls based on patients' 12-month recall; motor and non-motor function tests to detect additional risk factors.

46% of patients and 16% of controls fell at least once a year. Patients with stroke (89%), Parkinson's disease (77%), dementia (60%) or epilepsy (57%) had a particularly high proportion of fallers, but even subgroups of patients with the least fall-associated neurological diseases like tinnitus (30%) and headache (28%) had a higher proportion of fallers than the control group. Neuropathies, peripheral nerve lesions and Parkinson's disease were predisposing to recurrent falls. A higher number of neurological comorbidities (p<0.001), lower Barthel Index values (p<0.001), lower Activities-Specific Balance Confidence scores (p<0.001) and higher Center of Epidemiological Studies Depression scores (p<0.001) as well as higher age (p<0.001) and female gender (p=0.003) proved to further increase the risk of falls.

Medical practitioners, allied health professionals and carers should be aware that all elderly neurological patients seen in outpatient settings are potentially at high risk for falls; they should query them routinely about previous falls and fall risks and advise them on preventive strategies.
