Objective: To evaluate motor and nonmotor symptoms in patients with Parkinson’s disease undergoing bilateral deep brain stimulation of the subthalamic nucleus (STN DBS). Methods: Thirty-six consecutive patients receiving bilateral STN stimulation implants were evaluated preoperatively as well as 12 and 24 months after surgery. Motor symptoms were assessed through the Unified Parkinson’s Disease Rating Scale (UPDRS). Data concerning nonmotor symptoms were collected from items of the UPDRS and 2 additional questions from clinical charts regarding constipation and urological dysfunction. Results: STN DBS was effective in controlling motor symptoms; concerning nonmotor symptoms, sleep quality and constipation improved after surgery as compared to baseline. Salivation, swallowing and sensory complaints were ameliorated to a comparable degree by the medication on state, whether preoperatively or postoperatively. With a lower dose of dopaminergic medication, however, the medication on state appeared to be a much larger percentage of the day postoperatively. No significant variations were detected in intellectual impairment, depression, thought disorders, motivation, falling unrelated to freezing, nausea, orthostatic hypotension and urological dysfunction. Conclusions: STN DBS effectively controls motor symptoms, while nonmotor features of advanced Parkinson’s disease patients are mostly unchanged after surgery, even though some specific aspects, notably sleep complaints and constipation, are ameliorated.

Objectives: To evaluate changes in sexual well being in a group of patients with Parkinson’s disease following deep brain stimulation (DBS) of the subthalamic nucleus (STN). Methods: 31 consecutive patients with Parkinson’s disease (21 men and 10 women), bilaterally implanted for DBS of STN, were evaluated one month before and 9–12 months after surgery. Sexual functioning was assessed using a reduced form of the Gollombok Rust inventory of sexual satisfaction (GRISS). Depression (Beck depression inventory) and anxiety (STAI-X1/X2) were also evaluated. Relations between sexual functioning and modifications in the severity of disease (Hoehn and Yahr stage), reduction in levodopa equivalent daily dosage (LEDD), age, and duration of disease were analysed. Results: While no modifications were found in female patients, male patients reported slightly but significantly more satisfaction with their sexual life after DBS of STN. When only male patients under 60 years old were considered, a greater improvement in sexual functioning was found, though still small. Modifications in depressive symptoms and anxiety, as well as duration of the disease, reduction in LEDD, and improvement in the severity of disease, showed no relation with changes in sexual functioning after DBS of STN. Conclusions: DBS of STN appears to affect sexual functioning in a small but positive way. Male patients with Parkinson’s disease, especially when under 60, appeared more satisfied with their sexual well being over a short term follow up period.

We report a case of a Parkinsons disease patient treated by bilateral deep brain stimulation of the subthalamic nucleus, who developed freezing and hypokinesia of gait induced by stimulation through a left-side misplaced electrode which was more antero-medial than the planned trajectory. Subsequently, correct repositioning of the left electrode afforded complete relief of gait disturbances. Freezing and hypokinesia of gait may be side effects of deep brain stimulation of the subthalamic region due to current spreading antero-medially to the subthalamic nucleus. These side effects are not subject to habituation and restrict any increase in stimulation parameters. We hypothesize that pallidal projections to the pedunculopontine nucleus could be responsible for these gait disturbances in our patient.

OBJECTIVE This study reports a retrospective analysis of 67 consecutive parkinsonian patients to assess changes in antiparkinsonian medications after Deep Brain Stimulation (DBS) of the Subthalamic Nucleus (STN). METHODS All antiparkinsonian drugs, including levodopa, dopamine agonists, associated drugs such as COMT and MAO inhibitors, amantadine and anticholinergics, were evaluated pre- and post-operatively at 1 and 3 years follow-up. RESULTS The levodopa mean daily dose was reduced approximately 60% after 1 year and remained stable after 3 years. Apomorphine, bromocriptine, tolcapone, entacapone and selegiline were withdrawn after STN DBS. Three years post-operatively, 9 patients (13.4%) no longer required levodopa and 6 patients (8.9%) completely stopped all dopaminergic medications. More patients were on monotherapy of either levodopa or dopamine agonist and fewer patients required a combined treatment of dopamine agonist and levodopa, compared to the pre-surgical condition. CONCLUSIONS STN DBS treated PD patients experience a significant long-term reduction and simplification of the pharmacological treatment.

BACKGROUND The prevalence of psychiatric comorbidity in Parkinsons disease (PD) is about 50%. OBJECTIVE The authors investigated differences among PD patients treated by deep brain stimulation (DBS), by drugs alone (noDBS), and healthy control subjects. METHOD Samples of 22 subjects in each group were assessed with the Temperament and Character Inventory (TCI) and Hamilton scales for anxiety and depression (Ham-A and Ham-D). RESULTS Higher scores emerged on two Novelty-Seeking subscales in PD-DBS patients. Ham-A and Ham-D scores were lower in PD-DBS patients than in PD-noDBS patients and control subjects. Rigidity and non-impulsiveness were lower in PD-DBS than in PD-noDBS patients. CONCLUSION Further studies should investigate whether or not these changes in personality are a consequence of the motor and depression improvement after DBS.

OBJECTIVE To assess whether the presence of probable REM sleep behaviour disorder (pRBD) influences the long-term outcome of Parkinsons Disease (PD) patients undergoing Subthalamic Nucleus Deep Brain Stimulation (STN-DBS). BACKGROUND RBD is a parasomnia characterized by loss of muscular atonia and complex motor behaviours during REM sleep, frequently reported in PD patients. Recent evidence suggests that RBD is associated with akinetic rigid disease type and increased frequency of falls. We wondered whether the presence of RBD would also influence the long-term outcome of STN-DBS. METHODS Forty-one consecutive PD patients treated with bilateral STN-DBS were assessed. The diagnosis of pRBD was based on a clinical interview investigating the occurrence of diagnostic criteria for RBD. The Unified Parkinsons Disease Rating Scale was used to compare the on- and off-medication conditions preoperatively and the on-stimulation/on- and off-medication conditions 1 and 3 years postoperatively. The general linear model for multivariate measures was used to analyse the interaction of pRBD with STN-DBS outcome measures. RESULTS pRBD was present in 12 out of 41 patients (29%) undergoing STN-DBS. Patients with pRBD had a significantly poorer outcome three years after STN-DBS compared to patients without pRBD, in particular for axial symptoms. CONCLUSIONS Our findings suggest that the presence of pRBD in PD patients undergoing STN-DBS may be associated with a less favourable outcome and a more prominent development of axial symptoms over time.

BACKGROUND Neuro-psychiatric (NP) disturbances are highly prevalent in patients with Parkinsons disease (PD) and contribute to worsen quality of life. Deep brain stimulation of the subthalamic nucleus (STN-DBS) is commonly utilized as surgical treatment for advanced PD with motor complications. The effectiveness of the procedure on motor symptoms is well established whereas the effects of STN-DBS on NP symptoms are less clear. The aim of our study was to analyze the postoperative pharmacological therapy for NP symptoms in a group of STN-DBS treated PD patients. Such therapy provides indirect information about the evolution of underlying NP disturbances during the follow-up in this group of PD patients. METHODS NP therapy (benzodiazepines, antidepressants, antipsychotics) was assessed in 48 consecutive PD patients treated by STN-DBS, preoperatively and postoperatively after 4 months, 1 year and 3 years. Motor symptoms were evaluated by the Unified PD Rating Scale (UPDRS) and levodopa equivalence daily dose (LEDD) was calculated. Cognitive, mood and anxiety assessments were performed with appropriate rating scales. RESULTS The number of patients treated with antidepressant drugs gradually increased during the follow-up. The use of antipsychotic drugs was stable until 1 year, with a subsequent increase at 3 years. Benzodiazepines were given to fewer patients immediately after surgery. CONCLUSIONS Pharmacological treatment supplies further information about NP symptoms in the follow-up of PD patients undergoing STN stimulation.

Background/Aims: Patients with advanced Parkinson disease (PD) are at increased risk for asymptomatic leg deep venous thrombosis (DVT) because of severe motor fluctuations. Protracted immobility in the absence of antiparkinsonian therapy during stereotactic surgery may further increase the risk for venous thrombosis. Our aim was to determine the incidence of asymptomatic DVT of leg veins in PD patients undergoing subthalamic nucleus deep brain stimulation (STN-DBS). Methods: 41 consecutive PD patients undergoing stereotactic surgery for STN-DBS were investigated by ultrasound compression sonography of leg veins and D-dimer measurement in the week preceding surgery. After surgery, D-dimer measurements were repeated and when the value exceeded the normal range, ultrasound compression sonography was repeated to confirm or exclude DVT. Results: Doppler ultrasonographic examinations demonstrated that 2 patients (4.9%) developed asymptomatic DVT shortly after surgery (8.5 days) despite the fact that none of the 41 patients submitted to STN-DBS had DVT before surgery and that a specific prophylaxis was applied during surgery. Conclusions: Our data show that advanced PD patients are at risk for developing asymptomatic leg DVT following stereotactic surgery performed for STN-DBS. A strict clinical monitoring in the perioperative period is advisable in order to ensure early detection of DVT and prevent further thrombo-embolic complications.

OBJECTIVE This article reports the detailed analysis of antiparkinsonian drug therapy in 78 consecutive Parkinsons disease (PD) patients undergoing deep brain stimulation (DBS) of the subthalamic nucleus (STN). METHODS The amount and type of antiparkinsonian drugs--including L-dopa, dopamine receptor agonists, associated drugs such as catechol-O-methyl transferase and monoamine oxidase inhibitors, amantadine and anticholinergics--were quantified before surgery and at two control visits 1 and 3 years following chronic STN stimulation. RESULTS The L-dopa mean daily dose was reduced by approximately 60% after 1 year and remained stable after 3 years. Apomorphine, bromocriptine, tolcapone and selegiline were withdrawn after STN-DBS. Three years postoperatively, 9 patients (11.5%) no longer required L-dopa and 6 patients (7.7%) completely stopped all dopaminergic medications. More patients were on monotherapy with either L-dopa or dopamine receptor agonist, and fewer patients required combined treatment of dopamine receptor agonist and L-dopa compared with the pre-surgical condition. CONCLUSIONS Dopaminergic drug treatment is persistently reduced and simplified following chronic STN-DBS for up to 3 years.
