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.

Mild Cognitive Impairment among LRRK2 and GBA1 patients with Parkinson's Disease
Mild cognitive impairment (MCI) is common in Parkinson ’s disease (PD). We aimed to assess the incidence of MCI among patients with PD, carriers of mutations in LRRK2 and GBA1 genes, based on the movement disorder society (MDS) criteria for the diagnosis of MCI in early-stage PD.

Can symptoms or signs of cervical dystonia occur without abnormal movements of the head or neck?
Cervical dystonia is defined by excessive contraction of muscles that produce abnormal postures and movements of the head, neck, and sometimes the shoulders. Many affected individuals also have pain, local muscle hypertrophy, and/or abnormally increased EMG activity. However, abnormal movements are considered the defining feature.

Parkinsonism outcomes in different settings: how the type of care matters
Parkinson ’s disease (PD) is the second most prevalent neurodegenerative disease worldwide and probably in the next years the number of individuals affected with PD over age 50 will double [1]. Moreover, there are other neurodegenerative conditions, such as progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), dementia with Lewy bodies (DLB) and multiple system atrophy (MSA), that along with PD are parkinsonisms (PKM) [2].

Spinocerebellar ataxia subtype 40: Report of a case and review of literature
Spinocerebellar ataxias (SCA) are a group of neurodegenerative disorders and are clinically and genetically heterogeneous. Based on the genetic variation, SCAs are grouped into three main categories: i. SCAs caused by expansion of trinucleotides (CAG/polyQ) repeats in the coding region of genes, ii. SCAs caused by repetitive amplification of non-coding regions, and ii. SCAs caused by conventional sequence variants [1]. SCA40 (OMIM # 616053), which is one of the recently described types of autosomal dominant (AD) SCA, belongs to the third category and is caused by heterozygous pathogenic variants in the CCDC88C gene (OMIM *...
