    Long-term follow-up of impulse control disorders in Parkinson's disease

    MOVEMENT DISORDERS, Issue 1 2008
    Eugenia Mamikonyan MS
    Abstract Recent studies have linked dopamine agonist (DA) usage with the development of impulse control disorders (ICDs) in Parkinson's disease (PD). Little is known about optimal management strategies or the long-term outcomes of affected patients. To report on the clinical interventions and long-term outcomes of PD patients who developed an ICD after DA initiation. Subjects contacted by telephone for a follow-up interview after a mean time period of 29.2 months. They were administered a modified Minnesota Impulse Disorder Interview for compulsive buying, gambling, and sexuality, and also self-rated changes in their ICD symptomatology. Baseline and follow-up dopamine replacement therapy use was recorded and verified by chart review. Of 18 subjects, 15 (83.3%) participated in the follow-up interview. At follow-up, patients were receiving a significantly lower DA levodopa equivalent daily dosage (LEDD) (Z = ,3.1, P = 0.002) and a higher daily levodopa dosage (Z = ,1.9, P = 0.05), but a similar total LEDD dosage (Z = ,0.47, P = 0.64) with no changes in Unified Parkinson's Disease Rating Scale motor score (Z = ,1.3, P = 0.19). As part of ICD management, 12 (80.0%) patients discontinued or significantly decreased DA treatment, all of whom experienced full or partial remission of ICD symptoms by self-report, and 10 (83.3%) of whom no longer met diagnostic criteria for an ICD. For PD patients who develop an ICD in the context of DA treatment, discontinuing or significantly decreasing DA exposure, even when offset by an increase in levodopa treatment, is associated with remission of or significant reduction in ICD behaviors without worsening in motor symptoms. © 2007 Movement Disorder Society [source]


    Memory and executive function impairment predict dementia in Parkinson's disease

    MOVEMENT DISORDERS, Issue 6 2002
    Gilberto Levy MD
    Abstract We analyzed the association of neuropsychological test impairment at baseline with the development of dementia in idiopathic Parkinson's disease (PD) patients. A cohort of nondemented PD patients from northern Manhattan, NY was followed annually with neurological and neuropsychological evaluations. The neuropsychological battery included tests of verbal and nonverbal memory, orientation, visuospatial ability, language, and abstract reasoning. The association of baseline neuropsychological tests scores with incident dementia was analyzed using Cox proportional hazards models. The analysis controlled for age, gender, education, duration of PD, and the total Unified Parkinson's Disease Rating Scale motor score at baseline. Forty-five out of 164 patients (27%) became demented during a mean follow-up of 3.7 ± 2.3 years. Four neuropsychological test scores were significantly associated with incident dementia in the Cox model: total immediate recall (RR: 0.92, 95% CI: 0.87,0.97, P = 0.001) and delayed recall (RR: 0.73, 95% CI: 0.59,0.91, P = 0.005) of the Selective Reminding Test (SRT), letter fluency (RR: 0.87, 95% CI: 0.77,0.99, P = 0.03), and Identities and Oddities of the Mattis Dementia Rating Scale (RR: 0.85, 95% CI: 0.73,0.98, P = 0.03). When the analysis was performed excluding patients with a clinical dementia rating of 0.5 (questionable dementia) at baseline evaluation, total immediate recall and delayed recall were still predictive of dementia in PD. Our results indicate that impairment in verbal memory and executive function are associated with the development of dementia in patients with PD. © 2002 Movement Disorder Society [source]


    How much phenotypic variation can be attributed to parkin genotype?

    ANNALS OF NEUROLOGY, Issue 2 2003
    Ebba Lohmann MD
    To establish phenotype,genotype correlations in early-onset parkinsonism, we have compared the phenotype of a large series of 146 patients with and 250 patients without parkin mutations. Although no single sign distinguished the groups, patients with mutations had significantly earlier and more symmetrical onset, dystonia more often at onset and hyperreflexia, slower progression of the disease, and a tendency toward a greater response to levodopa despite lower doses. After forward stepwise multiple logistic regression analysis, dystonia at onset and brisk reflexes were not longer significantly different but were correlated with age at onset rather than the presence of the parkin mutation. Age at onset in carriers of parkin mutations varied as did the rate of progression of the disease: the younger the age at onset the slower the evolution. The genotype influenced the phenotype: carriers of at least one missense mutation had a higher United Parkinson's Disease Rating Scale motor score than those carrying two truncating mutations. The localization of the mutations was also important because missense mutations in functional domains of parkin resulted in earlier onset. Patients with a single heterozygous mutation had significantly later and more asymmetrical onset and more frequent levodopa-induced fluctuations and dystonia than patients with two mutations.

    Chronic bilateral subthalamic deep brain stimulation in a patient with homozygous deletion in the Parkin gene

    MOVEMENT DISORDERS, Issue 12 2004
    Marianna Capecci MD
    Abstract Chronic subthalamic nucleus deep brain stimulation (STN-DBS) is an efficacious treatment for idiopathic Parkinson's disease (PD) that cannot be further improved by medical therapy. We present a case of an individual with juvenile parkinsonism caused by homozygous deletion of exon 3 in the parkin gene with disabling long-term side-effects from levodopa who underwent bilateral STN neuromodulation. Parkin-linked parkinsonism may show clinical features different from sporadic PD, yet it shares levodopa responsiveness. Because levodopa responsiveness is a predictor of STN-DBS efficacy, we argued that this kind of surgical approach might be efficacious in hereditary parkin-linked juvenile parkinsonism. We evaluated clinical and functional assessment before and 12 months after surgery. The results showed that the Unified Parkinson Disease Rating Scales Motor score improved by 84% in our patient, the levodopa equivalent daily dose medication (LEDD) was reduced by 66%, and, finally, disabling and severe dyskinesias disappeared. © 2004 Movement Disorder Society [source]


    Asymmetrical lateral ventricular enlargement in Parkinson's disease

    EUROPEAN JOURNAL OF NEUROLOGY, Issue 4 2009
    M. M. Lewis
    Background:, A recent case report suggested the presence of asymmetrical lateral ventricular enlargement associated with motor asymmetry in Parkinson's disease (PD). The current study explored these associations further. Methods:, Magnetic resonance imaging (3T) scans were obtained on 17 PD and 15 healthy control subjects at baseline and 12,43 months later. Baseline and longitudinal lateral ventricular volumetric changes were compared between contralateral and ipsilateral ventricles in PD subjects relative to symptom onset side and in controls relative to their dominant hand. Correlations between changes in ventricular volume and United Parkinson's disease rating scale motor scores (UPDRS-III) whilst on medication were determined. Results:, The lateral ventricle contralateral to symptom onset side displayed a faster rate of enlargement compared to the ipsilateral (P = 0.004) in PD subjects, with no such asymmetry detected (P = 0.312) in controls. There was a positive correlation between ventricular enlargement and worsening motor function assessed by UPDRS-III scores (r = 0.96, P < 0.001). Discussion:, There is asymmetrical lateral ventricular enlargement that is associated with PD motor asymmetry and progression. Further studies are warranted to investigate the underlying mechanism(s), as well as the potential of using volumetric measurements as a marker for PD progression. [source]
