Pisa syndrome was first described in 1972 in patients treated with neuroleptics. Since 2003, when it was first reported in patients with Parkinson's disease (PD), Pisa syndrome has progressively drawn the attention of clinicians and researchers. Although emerging evidence has partially clarified its prevalence and pathophysiology, the current debate revolves around diagnostic criteria and assessment and the effectiveness of pharmacological, surgical, and rehabilitative approaches. Contrary to initial thought, Pisa syndrome is common among PD patients, with an estimated prevalence of 8...

Several neurodegenerative diseases are driven by the toxic gain-of-function of specific proteins within the brain. Elevated levels of alpha-synuclein (α-Syn) appear to drive neurotoxicity in Parkinson's disease (PD); neuronal accumulation of tau is a hallmark of Alzheimer's disease (AD); and their increased levels cause neurodegeneration in humans and model organisms. Despite the clinical differences between AD and PD, several lines of evidence suggest that α-Syn and tau overlap pathologically. The connections between α-Syn and tau led us to ask whether these proteins might be regulated through a shared pathway...

BACKGROUND: Dexmedetomidine is a selective alpha-2 adrenergic agonist with sedative, analgesic, and anxiolytic properties. Dexmedetomidine has not been approved for use in pediatrics. Dexmedetomidine has been reported to depress sinus node and atrioventricular nodal function in pediatric patients; it has been suggested that the use of dexmedetomidine may not be desirable during electrophysiological studies. AIM: We hypothesize that the use of dexmedetomidine does not inhibit the induction of supraventricular tachyarrhythmias (SVT) during electrophysiological studies and does not inhibit the ablation of such arrhythmias...

Motor and non-motor symptoms associated with Parkinson's disease (PD) place individuals at greater risk of sedentary behaviors and comorbidities. Physical activity is one modifiable means to improving health and reducing risk of morbidity. We applied a behavioral framework to classify existing research on physical activity and PD to describe the current evolution and inform knowledge gaps in this area. Research placed in Phase 1 establishes links between physical activity and health-related outcomes; Phase 2 develops approaches to quantify physical activity behavior; Phase 3 identifies factors associated with implementation of physical activity behaviors; Phase 4 assesses the effectiveness of interventions to promote activity; Phase 5 disseminates evidence-based recommendations...

Parkinsonian signs are common in patients with Alzheimer's disease (AD) of mild degree and predict functional decline, but their relationship with gait speed and balance is unclear. The aims of this study were to describe characteristics of patients with parkinsonian signs among 98 patients with AD of mild degree (with no comorbid Parkinson's disease), and to examine associations between parkinsonian signs with gait speed and balance. A cross sectional study at a memory clinic was conducted. Presence of each parkinsonian sign (bradykinesia, rigidity and tremor) was derived from the UPDRS, regular gait speed was recorded over 10m and balance were assessed using the Mini-Balance Evaluation Systems Test (Mini-BESTest)...

BACKGROUND: A disturbed circadian rhythm seems to be a causal factor in the occurrence of depressive disorders in patients with Parkinson's disease (PD). The circadian rhythm can be restored with light. Therefore, Bright Light Therapy (BLT) might be a new treatment option for depression in PD patients. METHODS/DESIGN: In this double-blind controlled trial, 84 subjects with idiopathic PD are randomized to either BLT or a control light condition. The BLT condition emits white light with an intensity of 10,000 Lux, while the control device emits dim white light of 200 Lux, which is presumed to be too low to influence the circadian rhythm...

BACKGROUND: Patients with Parkinson's disease (PD) and/or Parkinsonism are affected by a complex burden of comorbidity. Many ultimately require institutional care, where they may be subject to the application of physical restraints or the prescription of antipsychotic medications, making them more vulnerable to adverse outcomes. OBJECTIVES: The objectives of this paper are to: 1) describe the clinical complexity of older institutionalized persons with PD; and 2) examine patterns and predictors of restraint use and prescription of antipsychotics in this population...

Epilepsy is an uncommon comorbidity of Parkinson's disease (PD) and has been considered not directly associated with PD. We present five patients (3 men and 2 women; ages 49-85) who had concomitant PD and cryptogenic epilepsy. Although rare, epilepsy can coexist with PD and their coexistence may influence the progression of PD. While this may be a chance association, an evolving understanding of the neurophysiological basis of either disease may suggest a mechanistic association.

BACKGROUND: Individuals with Parkinson's disease (PD) may have an increased risk of overall mortality compared to the general population. Women may have lower mortality rates from PD than men; however, studies among women on the effect of PD on mortality have been limited and may not have adequately controlled for confounding by comorbidities. METHODS: We conducted a matched cohort study among participants in the Women's Health Study. 396 incident PD cases were identified through self-report...

BACKGROUND: Previous studies reported that slower gait speed might predict cognitive impairment and dementing illnesses, supporting the role of gait speed as a possible subclinical marker of cognitive impairment. However, the predictive value of other gait parameters for cognitive decline is unclear. OBJECTIVE: To investigate and compare the association with, and prediction of, specific gait parameters for cognition in a population-based sample. METHODS: The analysis included 3,426 cognitively normal participants enrolled in the Mayo Clinic Study of Aging...

New insights into the pathophysiological mechanisms behind late-onset neurodegenerative diseases have come from unexpected sources in recent years. Specifically, the group of inherited metabolic disorders known as lysosomal storage diseases that most commonly affect infants has been found to have surprising similarities with adult neurodegenerative disorders. Most notable has been the identification of Gaucher's disease as a comorbidity for Parkinson's disease. Prompted by the recent identification of neuronal aggregates of α-synuclein in another lysosomal storage disease, Krabbe's disease, we propose the idea that a similar connection exists between adult synucleinopathies and Krabbe's...

Patients with Parkinson's disease (PD) may experience falls and/or fractures as a result of disease symptoms. There are limited data available from long-term studies estimating the incidence of falls/fractures in patients with PD. The objective was to compare the incidence rate of falls/fractures in PD patients with non-PD patients in a US population. This was a retrospective study using a US-based claims database (Truven Health MarketScan®) that compared the incidence rate of falls/fractures in PD subjects with non-PD subjects...

BACKGROUND: Apathy is one of the most common neuropsychiatric symptoms in Parkinson's disease (PD). Few studies have investigated the cognitive and neuroanatomical correlates of apathy in PD, and those which have done so have not controlled for the presence of other neuropsychiatric comorbidities. OBJECTIVE: To explore the cognitive and neuroanatomical correlates of apathy in PD at a mild disease stage. METHODS: Sixty-five PD patients and 24 healthy controls participated in this study...
