RESUMOIntrodução: A estimulação cerebral profunda (ECP) é eficaz na doença de Parkinson (DP) avançada, melhorando sintomas motores, flutuações e a qualidade de vida. No entanto, têm sido reportados efeitos adversos psiquiátricos, mas de uma forma variável e não padronizada. O objectivo deste artigo é analisar e sumarizar a evidência publicada sobre sintomas depressivos e ansiedade em doentes com DP após ECP, através de revisão sistemática e meta-análise. Material e Métodos: A PubMed foi pesquisada até Maio 2012 para identificar os estudos que avaliaram sintomas depressivos e ansiedade em doentes com doença de Parkinson submetidos a estimulação cerebral profunda bilateral do núcleo subtalâmico (NST) ou globo pálido interno (GPi). Foram feitas meta-análises com modelo de efeitos aleatórios para grupos de pelo menos três estudos homogéneos em relação ao desenho e instrumentos utilizados. Resultados: Foram selecionadas 63 referências; 98,4% continham dados relativos a escalas de avaliação de depressão e 38,1% relativos a ansiedade. Dois estudos não discriminavam o alvo usado; nos restantes 61 foi feita avaliação de curto prazo em 37 (60,7%), de médio prazo em 36 (59,0%) e de longo prazo em 5 (8,2%). Foram encontrados dados sobre variação pré/pós operatória em 57 (93,4%) estudos e 16 (26,2%) continham dados comparando ECP-NST versus outros grupos: ECP-GPi (n = 4 estudos, 25,0%), elegíveis para cirurgia (n = 6, 37,5%), e tratamento médico (n = 7, 43,8%). Discussão: É aparente a melhoria de depressão e ansiedade após ECP, sobretudo a curto prazo, efeito que tende a esbater-se em avaliações posteriores. Em relação à depressão a ECP-NST mostrou-se superior ao tratamento médico, mas não em comparação com o grupo de controlo elegível para cirurgia. Verificou-se o resultado oposto para a ansiedade, uma vez que os resultados favorecem o tratamento médico sobre a ECP-NST, e esta sobre o grupo de elegíveis para cirurgia. Não é evidente a superioridade de um alvo sobre o outro, mas os dados favorecem ligeiramente o GPi para ambos os tipos de sintomas. Conclusões:O padrão e curso dos sintomas depressivos e ansiedade após ECP na DP não são claros, mas ambos parecem melhorar no curto prazo, especialmente a depressão após a ECP-NST. Os resultados são bastante heterogéneos. Devem ser promovidos esforços no sentido de haver padronização de procedimentos de avaliação nos vários centros.

ABSTRACT Introduction: Deep brain stimulation (DBS) is effective in advancedParkinson's disease (PD), improving motor symptoms, fluctuations and quality of life. However, adverse psychiatric outcomes have been reported, albeit variably and in an unstandardized fashion. We aimed to summarize the published evidence on the outcomes of anxiety and depressive symptoms in Parkinson's disease patients following DBS, through systematic review and meta-analysis. Material and Methods: PubMed was searched until May 2012 to identify studies assessing anxiety and...

“…This technique is deep brain stimulation (DBS), and refers to the stereotaxic placement of unilateral or bilateral electrodes in target brain regions connected to a permanently implanted neurostimulator, which electrically stimulates that brain region (Schlaepfer and Lieb, 2005). Today, DBS is widely used as a treatment for symptoms of Parkinson's disease (Ghika et al, 1998;Greenberg and Rezai, 2003;McClelland et al, 2005). In these patients, electrodes are placed in the subthalamic nucleus or the globus pallidus internus, and provide immediate recovery to otherwise debilitating motor symptoms.…”

Deep brain stimulation (DBS) to different sites allows interfering with dysfunctional network function implicated in major depression.Because a prominent clinical feature of depression is anhedoniaFthe inability to experience pleasure from previously pleasurable activitiesFand because there is clear evidence of dysfunctions of the reward system in depression, DBS to the nucleus accumbens might offer a new possibility to target depressive symptomatology in otherwise treatment-resistant depression. Three patients suffering from extremely resistant forms of depression, who did not respond to pharmacotherapy, psychotherapy, and electroconvulsive therapy, were implanted with bilateral DBS electrodes in the nucleus accumbens. Stimulation parameters were modified in a double-blind manner, and clinical ratings were assessed at each modification. Additionally, brain metabolism was assessed 1 week before and 1 week after stimulation onset. Clinical ratings improved in all three patients when the stimulator was on, and worsened in all three patients when the stimulator was turned off. Effects were observable immediately, and no side effects occurred in any of the patients. Using FDG-PET, significant changes in brain metabolism as a function of the stimulation in fronto-striatal networks were observed. No unwanted effects of DBS other than those directly related to the surgical procedure (eg pain at sites of implantation) were observed. Dysfunctions of the reward systemFin which the nucleus accumbens is a key structureFare implicated in the neurobiology of major depression and might be responsible for impaired reward processing, as evidenced by the symptom of anhedonia. These preliminary findings suggest that DBS to the nucleus accumbens might be a hypothesis-guided approach for refractory major depression.

In particular, increasing levels of monoamine neurotransmitters in the synaptic cleft are associated with improvements of depressive symptoms. This insight led to a more targeted drug discovery process, resulting in drugs with fewer side effects, such as SSRIs. These medication treatments, in conjunction with certain methods of psychotherapy and electroconvulsive therapy, are effective at alleviating depressive symptomatology in most patients (Andrews and Nemeroff, 1994;Mann, 2005). However, these treatments do not work for all patients. A sizable minority of patients does not respond. Indeed, twelve percent of patients suffering from major depression have a poor outcome even after 5 years of treatment (Keller et al, 1992). Patien...

ResumenLos autores realizan una revisión crítica de la estimulación del núcleo subtalámico (NST) en la enfermedad de Parkinson (EP) a largo plazo (3-5 años). La estimulación del NST produce una mejoría significativa de la parte motora de la escala UPDRS (Unified Parkinson Disease Rating Scale) sin medicación a los 3-5 años de la cirugía. Los resultados muestran que los beneficios obtenidos tanto en el temblor, la rigidez, la bradicinesia y las disquinesias, así como la reducción de la medicación están mantenidos significativamente a largo plazo. Otros signos de la enfermedad como la marcha y la estabilidad postural no se mantienen al comparar los beneficios al año de la cirugía. Un porcentaje alto de pacientes intervenidos muestra un deterioro cognitivo durante el seguimiento que puede estar relacionado con la propia evolución de la enfermedad. La conclusión es que la estimulación bilateral del NST continúa siendo efectiva a largo plazo pero debería considerarse la cirugía en un momento más precoz de la evolución de la enfermedad.PALABRAS CLAVE: Núcleo subtalámico.

Critical review of the subthalamic stimulation in Parkinson´s disease SummaryThe authors critically review subthalamic nucleus (STN) stimulation for Parkinson´s disease (PD) at long follow-up (3-5 years). Subthalamic stimulation induce a significant improvement during the "off" medication in the assessment motor score UPDRS (Unified Parkinson Disease Rating Scale) 3-5 years after surgery. Results show that the benefits obtained in tremor, rigidity, bradykinesia, dyskinesias induced by medication and levodopa reduction are significantly maintained during long term. The improvement in other clinical signs as gait and postural stability at long follow-up are not maintained comparing with the benefits obtained one year after surgery. A high percentage of patients show a cognitive disturbance during the follow-up period that may be correlated with the disease progression. The conclusion is that bilateral STN stimulation is an effective treatment for PD patients at long term but it should be considered earlier in the course of PD.
