Contribution of the GABAergic System to Non-Motor Manifestations in Premotor and Early Stages of Parkinson’s Disease
(Frontiers Media, 2019-10-30)
Non-motor symptoms are common in Parkinson's disease (PD) and they represent a major source of disease burden. Several non-motor manifestations, such as rapid eye movement sleep behavior disorder, olfactory loss, ...
Quantitative analysis of dysautonomia in patients with autonomic dysreflexia
(Springer, 2021-02-25)
Autonomic dysreflexia (AD) is a life-threatening condition for individuals with cervical or high-thoracic spinal cord injury (SCI). The profile of autonomic dysfunction in AD using validated clinical autonomic tests has ...
Myocardial MIBG scintigraphy in genetic Parkinson’s disease as a model for Lewy body disorders
(Springer-Verlag, 2018-10-15)
Purpose To identify myocardial sympathetic denervation patterns suggestive of Lewy body (LB) pathology in patients with genetic and idiopathic parkinsonisms by 123I-metaiodobenzylguanidine (MIBG) scintigraphy. Methods We ...
Small fiber neuropathy and phosphorylated alpha-synuclein in the skin of E46K- SNCA mutation carriers
(Elsevier, 2019-06-05)
Background and objective: In 2004 we described the E46K mutation in alpha-synuclein gene (E46K-SNCA), a rare point mutation causing an aggressive Lewy body disease with early prominent non-motor features and small fiber ...
Autonomic dysfunction is associated with neuropsychological and neuropsychiatric impairment in patients with Lewy body diseases
(Springer-Verlag GmbH Germany, 2020-03-13)
Objective: This study aimed to analyze the association of autonomic dysfunction with cognition, depression, apathy, and fatigue in Lewy body disease (LBD).
Methods: We included 61 patients [49 with idiopathic Parkinson’s ...
Prognostic factors for falls in Parkinson’s disease: a systematic review
(Springer Nature, 2024)
Background Falls represent a critical concern in Parkinson’s disease (PD), contributing to increased morbidity and reduced
quality of life.
Purpose We conducted a systematic review to assess the prognostic factors ...
Association of retinal neurodegeneration with the progression of cognitive decline in Parkinson’s disease
(Nature, 2024-01)
Retinal thickness may serve as a biomarker in Parkinson’s disease (PD). In this prospective longitudinal study, we aimed to determine if PD patients present accelerated thinning rate in the parafoveal ganglion cell-inner ...
Retinal thickness as a biomarker of cognitive impairment in manifest Huntington’s disease
(Springer Nature, 2023)
Background
Cognitive decline has been reported in premanifest and manifest Huntington’s disease but reliable biomarkers are lacking. Inner retinal layer thickness seems to be a good biomarker of cognition in other ...
Dysautonomia and small fiber neuropathy in post-COVID condition and Chronic Fatigue Syndrome
(BMC, 2023)
Background
Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) and post-COVID condition can present similarities such as fatigue, brain fog, autonomic and neuropathic symptoms.
Methods
The study included 87 ...
Plasma and serum alpha-synuclein as a biomarker in Parkinson's disease: A meta-analysis
(Elsevier, 2022-06)
Background
Reliable biomarkers for Parkinson's disease (PD) diagnosis are urgently needed. Alpha-synuclein (α-syn) and its proteoforms play a key role in PD pathology but in vivo measurements have raised conflicting ...
