Deep brain stimulation (DBS) has been widely used to control motor symptoms and improve quality of life inpatients with Parkinsons disease (PD). Recently, DBS in the subthalamic nucleus (STN) has become the preferred targetfor patients with mixed motor symptoms. Despite resultant motor and quality of life improvements, the procedure has beenassociated with cognitive decline, mainly in language skills, and also with psychiatric symptoms.
Objective:
To evaluatethe influence of DBS in the STN on cognition, mood and quality of life.Methods:
We studied 20 patients with PD submittedto DBS in the STN from May 2008 to June 2012 with an extensive battery of cognitive tests including memory, language,praxis, executive functions and attention assessments; the Parkinsons Disease Quality of Life Questionnaire (PDQ-39); and the Hospital Anxiety and Depression Scale (HAD), were applied both before and after the surgery. Data was analyze dusing SPSS version 17.0 and results compared using the paired Students test.Results:
A total of 20 patients with preand post-operative assessments were included. A statistically significant improvement was found in total score and onsubscales of mobility, activities of daily living and emotional well-being from the PDQ-39 (P=0.009, 0.025, 0.001 and0.034, respectively). No significant difference was found on the cognitive battery or mood scale.Conclusion:
DBS in theSNT improved quality of life in PD with no negative impact on cognitive skills and mood.
Estimulação cerebral profunda tem sido utilizada para controle das alterações motoras e melhorar qualidade devida dos pacientes com Doença de Parkinson (DP). Mais recentemente, DBS em núcleo subtalâmico (STN) tem sido o alvopreferencialmente escolhido para sintomas mistos. Apesar da melhora motora e da qualidade de vida, o procedimento temsido associado com declínio cognitivo, principalmente na linguagem e distúrbios psiquiátricos.
