. Background. Hypoxic-ischemic brain injury is one primary cause of long-term neurological disability, morbidity, and death worldwide. The decrease in blood flow and oxygen concentration leads to insufficient nutrient supply to the brain, energy depletion, increased free radical generation, and mitochondrial dysfunction. Perinatal asphyxia — the ox...

Based on clinical and experimental evidence, metabolic syndrome (MetS) and type 2 diabetes (T2D) are considered risk factors for chronic cerebral hypoperfusion (CCH) and neurodegeneration. Scientific evidence suggests that protein misfolding is a potential mechanism that explains how CCH can lead to either Alzheimer’s disease (AD) or vascular cogni...

Patients with Parkinson’s Disease (PD) experience REM sleep behavior disorder (RBD) more frequently than healthy controls. RBD is associated with torpid disease evolution. To test the hypothesis that differential genetic signatures might contribute to the torpid disease evolution in PD patients with RBD we compared the rate of genetic mutations in...

Some studies show that patients with mutations in the SNCA gene, which codifies for the alpha-synuclein protein, show a particular phenotype. The effects of SNCA Single Nucleotide Polymorphism (SNPs) in recently diagnosed, drug-naïve patients with PD have been less explored. Therefore, we set out to explore the differences in the clinical character...

The genetic basis of Neurogenic Orthostatic Hypotension (NOH) in Parkinson’s disease (PD) has been inadequately explored. In a cross-sectional study, we examined the association between NOH and PD-related single-nucleotide polymorphisms (SNPs) and mapped their effects on gene expression and metabolic and signaling pathways. Patients with PD, free f...

Background Cognitive impairment is a frequent disabling feature of Parkinson’s disease (PD). Orthostatic hypotension (OH) is treatable and may be a risk factor for cognitive impairment. Objective We conducted a systematic review and meta-analysis to examine the relationship between OH with PD-associated minimal cognitive impairment (PD-MCI) and dem...

Parkinson’s disease (PD) is an extrapyramidal disorder characterized by neuronal degeneration in several regions of the peripheral and central nervous systems. It is the second most frequent neurodegenerative disease after Alzheimer’s. It has become a major health problem, affecting 1% of the world population over 60 years old and 3% of people beyo...

Introduction We explored the potential clinical effects of angiotensin-II AT1 receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEIs) in patients from the Parkinson’s Progress Marker Initiative (PPMI) study database. Methods We included 423 newly diagnosed PD patients, free from antiparkinsonian treatment, from the PPMI. We c...
