Abstract PDF: Objective
Physiotherapy (PT), an effective strategy for managing Parkinson’s disease (PD), can influence healthcare utilization. We analyzed trends in healthcare utilization, PT interventions, and medical costs among patients with PD.
Methods
Using data from the Korean National Health Insurance Service from 2011 to 2020, we analyzed the number of patients with PD and their healthcare utilization and assessed the odds ratio (OR) for receiving regular PTs.
Results
Over 10 years, 169,613 patients with PD were present. The number of patients with PD increased annually from 49,417 in 2011 to 91,841 in 2020. Patients with PD receiving PT increased from 4,847 (9.81%) in 2011 to 13,163 (14.33%) in 2020, and PT prescriptions increased from 81,220 in 2011 to 377,651 in 2019. Medical costs per patient with PD have increased from 1,686 United States Dollars (USD) in 2011 to 3,201 USD in 2020. Medical expenses for each patient with PD receiving PT increased from 6,581 USD in 2011 to 13,476 USD in 2020. Moreover, Regular PTs were administered to 31,782 patients (18.74%) and conducted only through hospitalization. Those in their 50s with disabilities demonstrated a high OR for regular PTs, while those aged 80 years or older and residing outside Seoul had a low OR.
Conclusions
The PD burden increased in South Korea between 2011 and 2020, including an increase in healthcare utilization and medical costs. The significant rise in medical expenses can be associated with increased PD prevalence and PT interventions. Regular PT applications remain restricted and have barriers to access.

Objective
Neurodegeneration with brain iron accumulation (NBIA) represents a group of inherited movement disorders characterized by iron accumulation in the basal ganglia. Recent advances have included the identification of new causative genes and highlighted the wide phenotypic variation between and within the specific NBIA subtypes. This study aimed to investigate the current status of NBIA in Korea.
Methods
We collected genetically confirmed NBIA patients from twelve nationwide referral hospitals and from a review of the literature. We conducted a study to describe the phenotypic and genotypic characteristics of Korean adults with atypical pantothenate kinase-associated neurodegeneration (PKAN).
Results
Four subtypes of NBIA including PKAN (n = 30), PLA2G6-related neurodegeneration (n = 2), beta-propeller protein-associated neurodegeneration (n = 1), and aceruloplasminemia (n = 1) have been identified in the Korean population. The clinical features of fifteen adults with atypical PKAN included early focal limb dystonia, parkinsonism-predominant feature, oromandibular dystonia, and isolated freezing of gait (FOG). Patients with a higher age of onset tended to present with parkinsonism and FOG. The p.R440P and p.D378G mutations are two major mutations that represent approximately 50% of the mutated alleles. Although there were no specific genotype-phenotype correlations, most patients carrying the p.D378G mutation had a late-onset, atypical form of PKAN.
Conclusions
We found considerable phenotypic heterogeneity in Korean adults with atypical PKAN. The age of onset may influence the presentation of extrapyramidal symptoms.

Abstract PDF: Parkinson’s disease is a principal underlying disease of neuroleptic malignant syndrome (NMS) occurring in parkinsonian disorders, but NMS may occur in patients with progressive supranuclear palsy and multiple system atrophy. We report first patient with corticobasal degeneration (CBD) who developed NMS after abrupt reduction of antiparkinsonian medication and concurrent infection. It should be kept in mind that the prevention of infectious illness, which is common complication in parkinson-plus syndrome, is important, and dose reduction or withdrawal of anti-parkinsonian medications should be carefully performed even in the patients with CBD who are expected to be unresponsive to levodopa treatment.
