OBJECTIVES: Hypertension, dyslipidemia, diabetes, and obesity are well-established risk factors for cognitive impairment and dementia in older adults. In contrast, previous studies that have assessed the impact of vascular risk factors (VRFs) on cognition in Parkinson's disease (PD) have had methodological limitations and reported conflicting findings. We address this question in a large well-characterized cohort of de novo PD patients. METHODS: A total of 367 untreated and non-demented patients aged 50 years and older with early PD (H&Y = 1...

Importance: To our knowledge, a comprehensive study of the survival and causes of death of persons with synucleinopathies compared with the general population has not been conducted. Understanding the long-term outcomes of these conditions may inform patients and caregivers of the expected disease duration and may help with care planning. Objective: To compare survival rates and causes of death among patients with incident, clinically diagnosed synucleinopathies and age- and sex-matched referent participants...

Several studies have demonstrated clinical benefits of sustained cholinesterase inhibition with rivastigmine in Alzheimer's disease (AD) and Parkinson's disease dementia (PDD). Unlike donepezil and galantamine that selectively inhibit acetylcholinesterase (AChE; EC 3.1.1.7), rivastigmine is a unique cholinesterase inhibitor with both AChE and butyrylcholinesterase (BuChE; EC 3.1.1.8) inhibitory activity. Rivastigmine is also available as transdermal patch that has been approved by the US Food and Drug Administration for the treatment of mild, moderate, and severe AD as well as mild-to-moderate PDD...

OBJECTIVE: Neurodegenerative diseases, such as dementia, have a profound impact on those with the conditions and their family carers. Consequently, the accurate measurement of family carers' quality of life (QOL) is important. Generic measures may miss key elements of the impact of these conditions, so using disease-specific instruments has been advocated. This systematic review aimed to identify and examine the psychometric properties of disease-specific outcome measures of QOL of family carers of people with neurodegenerative diseases (Alzheimer's disease and other dementias; Huntington's disease; Parkinson's disease; multiple sclerosis; and motor neuron disease)...

OBJECTIVE: To evaluate a modified extended Timed Up and Go (extended-TUG) assessment against a panel of validated clinical assessments, as an indicator of Parkinson's disease (PD) severity and cognitive impairment. METHODS: Eighty-seven participants with idiopathic PD were sequentially recruited from a Movement Disorders Clinic. An extended-TUG assessment was employed which required participants to stand from a seated position, walk in a straight line for 7m, turn 180° and then return to the start, in a seated position...

Deep brain stimulation of subthalamic nucleus (STN-DBS) became a standard therapeutic option in Parkinson's disease (PD), even though the underlying modulated network of STN-DBS is still poorly described. Probabilistic tractography and connectivity analysis as derived from diffusion tensor imaging (DTI) were performed together with modelling of implanted electrode positions and linked postoperative clinical outcome. Fifteen patients with idiopathic PD without dementia were selected for DBS treatment. After pre-processing, probabilistic tractography was run from cortical and subcortical seeds of the hypothesized network to targets represented by the positions of the active DBS contacts...

While deep brain stimulation of the subthalamic nucleus (STN-DBS) has evolved to an evidence-based standard treatment for Parkinson's disease (PD), the targeted cerebral networks are poorly described and no objective predictors for the postoperative clinical response exist. To elucidate the systemic mechanisms of DBS, we analysed cerebral grey matter properties using cortical thickness measurements and addressed the dependence of structural integrity on clinical outcome. Thirty one patients with idiopathic PD without dementia (23 males, age: 63...

OBJECTIVE: To determine if antipsychotic (AP) use in Parkinson disease (PD) patients is associated with increased physical morbidity. METHODS: Veterans Health Administration data (1999-2010) was used to examine physical morbidity risk associated with AP use in idiopathic PD patients with stable recent physical health. We compared 180-day morbidity rates in patients initiating an AP with matched non-AP users who survived for 180 days (matched on age, sex, race, index year, presence and duration of dementia, PD duration, delirium, hospitalization, Charlson Comorbidity Index, and new non-psychiatric medications; covarying for psychosis)...

Laura A Bradfield, Bernard W Balleine
We (Bradfield et al. 2013) have previously demonstrated that parafascicular (PF)-controlled neurons in the posterior dorsomedial striatum (pDMS) are critical for interlacing new and existing action-outcome contingencies to control goal-directed action. Based on these findings it was suggested that animals with a dysfunctional PF-pDMS pathway might suffer a deficit in creating or retrieving internal contexts or 'states' on which such information could become conditional. To assess this hypothesis more directly rats were given a disconnection treatment using contralateral cytotoxic lesions of the parafascicular thalamic nucleus (PF) and pDMS (Group CONTRA) or ipsilateral control lesions (Group IPSI) and trained to press a right and left lever for sucrose and pellet outcomes after which these contingencies were reversed...

E S Fagan, L Pihlstrøm
Parkinson's disease is a highly heterogeneous disorder, where genetic factors are likely to contribute to clinical variability, including susceptibility to cognitive impairment and dementia. Monogenic forms of parkinsonism show distinct cognitive profiles, yet less is known about the impact of common genetic variants on cognition in sporadic Parkinson's disease. In a systematic review of the literature, the current results from genetic association studies of cognitive outcomes are summarized and prospects and challenges for future studies are discussed...

Experimental, neuropathological and cerebrospinal fluid (CSF) studies support τ and amyloid-β (Aβ) relevance in Parkinson's disease (PD) related dementia. Lesser motor fluctuations (MFs) and non-motor features have also been related to PD-dementia. Yet, little is known about the association of MFs and non-motor symptoms with CSF τ and Aβ in PD. We hypothesized that lesser MFs and non-motor predominance are related to these CSF markers and dementia-risk in PD. We studied 58 PD patients (dementia at baseline, n=21; dementia at 18-months, n=35) in whom CSF Aβ and τ had been determined with ELISA techniques...

Neurogenic orthostatic hypotension (nOH) is common in patients with neurodegenerative disorders such as Parkinson's disease, multiple system atrophy, pure autonomic failure, dementia with Lewy bodies, and peripheral neuropathies including amyloid or diabetic neuropathy. Due to the frequency of nOH in the aging population, clinicians need to be well informed about its diagnosis and management. To date, studies of nOH have used different outcome measures and various methods of diagnosis, thereby preventing the generation of evidence-based guidelines to direct clinicians towards 'best practices' when treating patients with nOH and associated supine hypertension...
