Primary disruption of the default mode network subsystems in drug-na ïve Parkinson’s disease with mild cognitive impairments

ConclusionThe DMPFC subsystem was predominantly disrupted in the PD-MCI subgroup and may have the potential to discriminate PD with MCI.

Authors: Femat-Roldán G, Gaitán Palau MA, Castilla-Cortázar I, Elizondo Ochoa G, Moreno NG, Martín-Estal I, Jiménez Yarza M Abstract Background: Weight loss in Parkinson's disease (PD) patients is a common but poorly understood manifestation. Several studies have reported that weight changes could be related to motor symptoms, drug side effects, dysphagia, depression, and/or dementia. Weight loss in PD is not a benign phenomenon and it has several clinical and prognostic implications with increased morbidity and mortality. Thus, it is crucial to determine nutritional changes in PD...

Conclusions: LCIG may affect PDrPD and reduce premature bolus spillage and pharyngeal bradykinesia. Future studies with larger sample sizes are required to follow-up on these pilot results and identify which factors predict a good response of PDrPD to LCIG treatment.

CONCLUSION: Optimal training duration was relatively short and the IPD group demonstrated the most gain, indicating that cognitive training should be tailored to individual needs. PMID: 32250326 [PubMed - as supplied by publisher]

Authors: Macerollo A, Zrinzo L, Akram H, Foltynie T, Limousin P Abstract Over the last three decades, extensive basic and clinical research has been performed on the use of subthalamic nucleus (STN) as the preferred deep brain stimulation (DBS) target for the treatment of Parkinson's disease (PD). The mechanism underlying the benefit for the motor symptoms in PD is related to the modulation of firing patterns within the hyperdirect projections from motor cortical areas, as well as within the afferent and efferent fibers to the motor STN. Advancements in neuroimaging techniques allow us to identify precisely the STN...

The TMEM175 family constitutes recently discovered K+ channels that are important for autophagosome turnover and lysosomal pH regulation and are associated with the early onset of Parkinson Disease. TMEM175 channels lack a P-loop selectivity filter, a hallmark of all known K+ channels, raising the question how selectivity is achieved. Here, we report the X-ray structure of a closed bacterial TMEM175 channel in complex with a nanobody fusion-protein disclosing bound K+ ions. Our analysis revealed that a highly conserved layer of threonine residues in the pore conveys a basal K+selectivity. An additional layer comprising two...
