Parkinson’s disease is a progressive disease of the brain caused by the death of special nerve cells. The disease is characterized by movement disorders such as slowing movements, stiffness of the muscles, tremors or specific changes in the gait pattern. Often there can be many years before these typical symptoms permit a diagnosis of Parkinson’s disease. These can […]

Our 3-Sniffin’-stick model holds potential utility as a brief screening test in the stratification of individuals with PD and iRBD according to olfactory dysfunction. CLICK TO REVIEW
About 33% of the patients with PD had pRBD based on the questionnaires, and both motor and non-motor functions were significantly decreased in these patients. These results suggest that more extensive degeneration occurred in patients with non-demented PD with RBD. CLICK TO REVIEW
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

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
The presence of olfactory dysfunction conveys a considerably elevated risk of incident PD, likely more in studies with a higher proportion of women, older individuals or short follow-up duration. Individual patient data are warranted to confirm these findings and to yield subgroup-specific risk estimates of other common markers to refine prodromal PD criteria. CLICK TO
Connectomic approaches reveal a number of hubs in the olfactory system (anterior olfactory nucleus, olfactory entorhinal cortex and cortical amygdala) that are key interconnectors with the main hubs (the entorhinal–hippocampal–cortical and amygdala–dorsal motor vagal nucleus) of network dysfunction in Alzheimer’s and Parkinson’s diseases.

We identified similar olfactory impairments in patients with RBD and patients with PD (either with or without underlying RBD). These findings suggest that olfactory impairment may be a sensitive and stable diagnostic biomarker of RBD and appears to be useful for identifying patients with idiopathic RBD at high risk for early conversion to PD.
