Clustering Algorithm Reveals Dopamine‐Motor Mismatch in Cognitively Preserved Parkinson's Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To explore the relationship between dopaminergic denervation and motor impairment in two de novo Parkinson's disease (PD) cohorts. Methods n = 249 PD patients from Parkinson's Progression Markers Initiative (PPMI) and n = 84 from an external clinical cohort.

VTA dopaminergic neurons regulate ethologically relevant sleep–wake behaviors
Nature Neuroscience, 2016 Dopaminergic ventral tegmental area (VTA) neurons are critically involved in a variety of behaviors that rely on heightened arousal, but whether they directly and causally control the generation and maintenance of wakefulness is unknown.

Circadian Rhythm Abnormalities in Parkinson's Disease from Humans to Flies and Back [PDF]
, 2018 Clinical and research studies have suggested a link between Parkinson\u2019s disease (PD) and alterations in the circadian clock. Drosophila melanogaster may represent a useful model to study the relationship between the circadian clock and PD.

Superoxide Radical Dismutation as New Therapeutic Strategy in Parkinson’s Disease [PDF]
, 2017 open4siAging is the biggest risk factor for developing many neurodegenerative disorders, including idiopathic Parkinson's disease (PD). PD is still an incurable disorder and the available medications are mainly directed to the treatment of symptoms in ...

Dopaminergic Enhancement of Cognitive Function [PDF]
Current Pharmaceutical Design, 2006 The ascending dopamine system of the mammalian brain has been associated with motor, mnemonic and goal-directed or reward-related behaviour. The most progress in understanding the cortical mechanisms of dopaminergic modulation of function has been made with regards to short-term mnemonic (or working memory) function.

Validity of a Wearable Digital Insole for Assessing Gait ON and OFF in Parkinson's Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Gait impairment is a distinctive symptom of Parkinson's disease that negatively impact mobility. We assessed the validity of wearable digital insoles against a validated reference gait analysis system for measuring select gait characteristics in patients with Parkinson's disease. Methods A comparative analysis between digital insoles

miR-425 deficiency promotes necroptosis and dopaminergic neurodegeneration in Parkinson’s disease
Cell Death and Disease, 2019 A major hallmark of Parkinson’s disease (PD) is the degeneration of dopaminergic neurons in the substantia nigra, and the causative mechanism is thought to be the activation of programmed neuronal death.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cognitive decline is a disabling and variable feature of Parkinson disease (PD). While cholinergic system degeneration is linked to cognitive impairments in PD, most prior research reported cross‐sectional associations. We aimed to fill this gap by investigating whether baseline regional cerebral vesicular acetylcholine transporter ...

Active inference, evidence accumulation, and the urn task [PDF]
, 2015 Deciding how much evidence to accumulate before making a decision is a problem we and other animals often face, but one that is not completely understood.
