Spectrum of Non-Motor Symptoms in Parkinson’s Disease

A-Synuclein, Biomarkers, Gut Dysbiosis, iRBD, Olfactory, Pre-PD /

Parkinson’s disease is predominantly classified as a movement disorder. Beyond the textbook definition of rigidity, tremors, and bradykinesia, Parkinson’s disease encompasses an entire entity of non-motor symptom complexes that can precede the motor features by many years. Despite their significant clinical importance, the awareness of non-motor symptoms is quite negligible. Sleep disorders, gastrointestinal dysfunction, olfactory […]

Smell tests to distinguish Parkinson’s disease from other neurological disorders: a systematic review and meta-analysis

Biomarkers, Olfactory, Pre-PD, Symptoms / Diagnosis /

Olfactory impairment has been considered for differential diagnosis in Parkinson’s Disease (PD) patients. The authors aimed to identify the tests used to assess the olfactory function in PD patients and examine these tests’ ability to distinguish them from other neurological disorders. CLICK TO REVIEW

Advances of Mechanisms-Related Metabolomics in Parkinson’s Disease

Biomarkers, Butyrate, Diet and Exercise, Gut Dysbiosis, Gut Microbiota, Mitochondria, Pre-PD, Short Chain Fatty Acids /

In this review, we briefly summarize recent findings and analyze the application of molecular metabolomics in familial and sporadic PD from genetic mutations, mitochondrial dysfunction, and dysbacteriosis. We also review metabolic biomarkers to assess the functional stage and improve therapeutic strategies to postpone or hinder the disease progression. CLICK TO REVIEW

Longitudinal analysis of premotor anthropometric and serological markers of Parkinson’s disease

Biomarkers, Pre-PD, Symptoms / Diagnosis /

Parkinson’s disease (PD) is a debilitating neurodegenerative disorder in which nonmotor symptoms, such as constipation and hyposmia, precede the onset of motor symptoms by 20 years. The aim of this study was to identify biomarkers at the premotor stage of PD. We assessed the differences in longitudinal changes in anthropometric and serological indices obtained from health
