RESUMEN
BACKGROUND: Deep brain stimulation improves motor function and quality of life in patients with Parkinson's disease. The impact of these changes on patients' spouses is largely unknown. METHODS: Twenty-six spouses of patients undergoing surgery were evaluated before and 12 months after surgery, using the 36-Item Short Form Health Survey for quality of life, the Beck Depression Inventory, and the Zarit Burden Inventory. RESULTS: The spouses' mean mood and quality of life scores changed little, while burden improved in younger spouses. There was no significant change in the spouses' overall status. However, at the individual level the effect of surgery was more frequently negative than positive. Changes in psychological status and quality of life in the spouses did not correlate with changes in the patients' motor status or quality of life. CONCLUSIONS: Spouses' experience of neurostimulation for Parkinson's disease is variable and complex. The improvement in burden experienced by younger spouses may reflect a greater capacity to cope with new situations.
