title: Deep brain stimulation for patients with Parkinson's disease: Effect on caregiver burden.
abstract: BACKGROUND
  Our aim is to assess the burden on caregivers of patients with Parkinson's disease treated with deep brain stimulation (DBS) compared to those caring for patients at advanced stages and undergoing other treatments. We have also assessed the variables associated with presence of caregiver overload.
  
  
  METHODS
  We included consecutive patients with Parkinson's disease treated with DBS. Our control group included patients in advanced stages of Parkinson's disease undergoing other treatments. Patients were assessed with the following scales: UPDRS-II, UPDRS-III, UPDRS-IV, Hoehn and Yahr, Schwab & England, Barthel, PDQ-39, MoCA, Apathy Evaluation Scale, HADS, and the abbreviated QUIP. Caregiver burden was evaluated with the Zarit caregiver burden interview and their moods were assessed with the HADS scale.
  
  
  RESULTS
  We included 11 patients treated with DBS and 11 with other treatments. For patients treated with DBS, we observed a better quality of life according to the PDQ-39 questionnaire (P=.028), and a lower score on the HADS anxiety subscale (P=.010). Caregiver overload was observed in 54.5% of the caregivers of patients in both groups (P=1.000); Zarit scores were similar (P=.835). Caregiver overload was associated with higher scores on the caregiver's Apathy Evaluation Scale (P=.048) and on the HADS anxiety subscale (P=.006).
  
  
  CONCLUSIONS
  According to our results, treatment with DBS is not associated with lower caregiver burden. Apathy in patients and anxiety in caregivers are factors associated with the appearance of overload.
