Objective: To evaluate the clinical correlates of fear of falling (FoF) in patients with Progressive Supranuclear Palsy (PSP) and Multiple System Atrophy (MSA)
Background: FoF leads to avoidance behaviors, functional decline, restriction of social participation, and an increased risk of falling and institutionalization; (1) FoF has also been associated with worst balance, recurrent falls, anxiety (2) and cognitive impairment(3). However, in atypical parkinsonisms like PSP and MSA, cognitive and psychiatric correlates to FoF remain understudied
Method: Patients with PSP and MSA were evaluated at baseline and at 6 months follow up with a daily falls diary. FoF was assessed with the International Falls Efficacy Scale (FES-I), and FoF was defined as FES-I > 28. Recurrent falls were defined as 2 or more falls in the follow up. Balance and Gait, Cognitive and Psychiatric scales were also administered
Results: 21 patients with PSP and 22 with MSA were included; There were no significant differences in sex, age, and disease duration. At baseline we found similar recurrent falls (in the last year), FoF scores, balance and gait functionality scales between PSP and MSA but worse than in control. At 6 months follow up, PSP patients had a higher number of falls than MSA patients (median 5 vs 2.5 p= <0.001). FoF was found in 76,2% of PSP and 86,4% MSA (p=0.3). FoF was not associated with recurrent falls (PSP p=0.12; MSA p= 0.5), but with worse balance, lower gait scores and anxiety in both PSP and MSA ( p=0.018 and 0.001). However, worse executive function was only associated with FoF in MSA (Phonological verbal fluency p=0.048; Frontal Assessment Battery p=0.037). Interestingly, worse cognitive and depression scores were found in Fearful non-Fallers, compared to Fearless non-Fallers. In addition worse cognitive , depression and apathy was found in Fearless Fallers compared to Fearless Non-fallers.
Conclusion: Fear of falling was associated with poorer balance, gait functionality and anxiety in both conditions PSP and MSA. Mood and Cognition independently of balance and gait performance, might contribute to development of FOF or the lack of FOF non congruent with patient falls
