Are the criteria for PD-MCI diagnosis comprehensive? A Machine Learning study with modified criteria
Mild cognitive impairment in Parkinson's disease (PD-MCI) includes deficits in different cognitive domains, and one domain to explore for neurocognitive impairment following the DSM-V is social cognition. However, this domain is not included in current criteria for PD-MCI diagnosis. Moreover, tests vary across studies. It is, therefore, crucial to optimize cognitive assessment in PD-MCI. We aimed to do so by using Machine Learning. (Source: Parkinsonism and Related Disorders)

Severity of sleep apnea as a prognostic factor for mortality in patients with multiple system atrophy
We determined whether the severity of sleep apnea increases the risk of mortality in patients with multiple system atrophy (MSA) with and without stridor.MethodsThis retrospective study included patients who underwent polysomnography within one year after diagnosis of probable MSA. Stridor, sleep apnea, and arousal from sleep were determined using full-night polysomnography. Disease severity was measured using the Unified MSA Rating Scale (UMSARS). Survival data were collected and analyzed using Cox regression analysis. (Source: Parkinsonism and Related Disorders)

Support Group for Parkinson ’s Disease Patients in Chicagoland of African Ancestry
Parkinson's disease (PD) patients from the Black community comprise a smaller percentage of patients in subspecialty movement disorder clinics despite being located in geographic areas with a high population of Black individuals.[1] In addition, few studies have been conducted to understand the specific needs of Parkinson ’s disease (PD) patients from the Black community. However, it has been shown that there are potential health benefits to receiving and providing social support among older African Americans [2]. (Source: Parkinsonism and Related Disorders)

Illustration of the Long-Term Efficacy of Pallidal Deep Brain Stimulation in a Patient with PKAN Dystonia
Pantothenate kinase-associated neurodegeneration (PKAN, PANK2, OMIM ID: 234200) represents the most common subtype of neurodegeneration associated with brain iron accumulation (NBIA). Treatment could be challenging due to the combination of severe motor and nonmotor features. Deep Brain Stimulation (DBS) may be a promising treatment for dystonia in selected PKAN patients [1]; however, due to the rarity of this genetic condition, the long-term efficacy of DBS on symptoms and disease evolution is unclear, as is its impact on patient independence.

Surgicogenomics in GBA1-Related Parkinson Disease: Is the Glass Half Full or Half Empty?
Genetic markers have been instrumental in our pursuit to fully understand Parkinson disease (PD), and “surgicogenomics” offers a promising new approach to further improve our decision-making for deep brain stimulation (DBS). But could this emerging knowledge be a game-changer in our clinical practice? So far, expectations seem to exceed applicability. (Source: Parkinsonism and Related Disorders)

The p.Val234Met LRP10 likely pathogenic variant associated with Parkinson ’s Disease: possible molecular implications.
the LRP10 gene has been associated with Lewy Body Diseases, including PD, Parkinson ’s Disease Dementia (PDD) and Dementia with Lewy Bodies (DLB) and it is characterised by autosomal dominant inheritance. In recent years, multiple studies have linked LRP10 pathogenic variants to PD, but the role played by the protein in the pathogenetic process is still unclear [1, 2]. Studies on patients carrying LRP10 pathological variants showed co-staining between LRP10 and α-synuclein in Levi’s Bodies present Substantia nigra pars compacta and in the core of brainstem type, but functional significance of this interaction remains ...

Cerebellar blood perfusion is a diagnostic, but not a prognostic, marker for parkinsonian-dominant type multiple system atrophy.
Multiple system atrophy (MSA) is clinically characterized by various neurological symptoms. According to the diagnostic criteria, MSA is classified into parkinsonian-dominant type (MSA-P) or cerebellar ataxia-dominant type (MSA-C) based on the predominant signs displayed. Recently, N-isopropyl-p-[123I] iodoamphetamine (123I-IMP) single-photon emission computed tomography (SPECT), a radiological examination evaluating brain perfusion, has been successful in detecting cerebellar hypoperfusion in MSA-P patients, demonstrating its utility in the early detection of cerebellar dysfunction.
