Hyperglycemia in type 2 diabetes leads to diabetic peripheral neuropathy (DPN) and neuropathic pain, yet the association between glycemic variability and painful DPN remains insufficiently evidenced. To address this, we conducted a prospective longitudinal cohort study involving adult type 2 diabetes patients at a medical center. DPN was identified using the Michigan Neuropathy Screening Instrument (MNSI), and neuropathic pain was assessed with the Taiwan version of the Douleur Neuropathique 4 (DN4-T) questionnaire.

Background: Limited evidence exists to support any specific medication over others to prevent dementia in older patients with type 2 diabetes (T2D). We investigated whether treatment with sodium-glucose cotransporter 2 (SGLT-2) inhibitors is associated with a lower risk of incident dementia and all-cause mortality, relative to dipeptidyl peptidase-4 (DPP-4) inhibitors and glucagon-like peptide-1 receptor agonists (GLP-1 RA).

Methods: In this retrospective, active-comparator cohort study, we used data from the TriNetX electronic health records network.

Background: We explore the effect of suboptimal glycemic control on the incidence of diabetic peripheral neuropathy (DPN) in both non-elderly and elderly patients with type 2 diabetes mellitus (T2DM).

Methods: A 6-year follow-up study (2013-2019) enrolled T2DM patients aged >20 without DPN. Participants were classified into two groups: those below 65 years (non-elderly) and those 65 years or older (elderly).

Background: Limited research has explored the relationship between the valence of olfactory dysfunction and PD clinical symptoms. This study aimed to investigate correlations between the emotional valence of olfactory impairment and different domains of PD symptoms.

Methods: PD patients who fulfilled the clinically probable PD diagnostic criteria of the International Parkinson and Movement Disorder Society Clinical Diagnostic Criteria for Parkinson's Disease were recruited from the Center for Parkinson and Movement Disorders at Taichung Veterans General Hospital between October 2016 and April 2022.

Article Synopsis
  • Olfactory dysfunction in Parkinson's disease (PD) was studied to see how it impacts cognitive function, disease severity, and quality of life over time in patients.
  • A cohort of 58 participants was evaluated over three years using various assessments, revealing that those with anosmia experienced more rapid cognitive decline compared to those without it.
  • Results showed that anosmic patients had a distinct cognitive trajectory influenced more by age and disease duration, while non-anosmic patients' olfactory function correlated with their motor abilities.

Background: The relationship between hyposmia and motor progression is controversial in Parkinson's disease (PD). The aim of this study was to investigate whether preserved identification of Chinese-validated University of Pennsylvania Smell Identification Test (UPSIT) odors could predict PD motor progression.

Methods: PD patients with two consecutive clinical visits while taking medication were recruited.

Introduction: Hyposmia is a common prodrome in patients with Parkinson's disease (PD). This study investigates whether olfactory changes in PD differ according to the degree of olfactory dysfunction and whether there are changes in motor and non-motor symptoms.

Methods: The 129 subjects with PD were divided into two groups: anosmia and non-anosmia.

Aims: Previous studies showed conflicting relationship between hyperlipidemia, lipid-lowering therapy and diabetic peripheral neuropathy (DPN). As most of these works emerges from the Western and Australian countries, our study aims to investigate whether hyperlipidemia or lipid-lowering therapy (LLT) is associated with DPN in Taiwanese patients with type 2 diabetes (T2D).

Methods: A cross-sectional, hospital-based observation study in adults with T2D was conducted from January to October 2013.

(1) Background: The correlation between dysosmia with quality of life (QoL) in patients with PD was rarely reported. The study aimed to examine the effect of dysosmia on motor function and QoL in PD. (2) Methods: This cross-sectional study, performed between October 2016 and February 2021, recorded the traditional Chinese version of the University of Pennsylvania Smell Identification Test (UPSIT), the Montreal Cognitive Assessment (MoCA), the Movement Disorder Society-sponsored revision of the Unified Parkinson’s Disease Rating Scale (MDS UPDRS), and the 39-item Parkinson’s Disease Questionnaire (PDQ-39) in patients with PD.

The relationship between renal impairment and diabetic peripheral neuropathy (DPN) remains inconclusive. We aim to investigate the risk factors for the occurrence of DPN in Taiwanese adults with type 2 diabetes mellitus (T2DM) and focus on renal impairment. A hospital-based study was conducted from 2013 to 2019 and 552 Taiwanese people who had T2DM without DPN at baseline were enrolled.

Parkinson's disease (PD) manifests with dominant motor symptoms and a wide range of non-motor symptoms (NMS). Dementia is one of the most disabling and exhausting NMS throughout the clinical course. We conducted a population-based, age-stratified, retrospective cohort study to investigate the incidence rate and risk of dementia of patients with newly diagnosed PD, and linked to the clinicopathological PD subtypes.

Blepharospasm (BSP) and hemifacial spasm (HFS) are both facial hyperkinesia however BSP is thought to be caused by maladaptation in multiple brain regions in contrast to the peripherally induced cause in HFS. Plausible coexisting pathophysiologies between these two distinct diseases have been proposed. In this study, we compared brain resting state functional connectivity (rsFC) and quantitative thermal test (QTT) results between patients with BSP, HFS and heathy controls (HCs).

Non-motor subtypes of Parkinson's disease (PD) include the limbic, cognitive, and brainstem phenotype, which may have different pathological pathways with olfaction. In this work, we aim to clarify the association between olfactory dysfunction, depression, cognition, and disease severity in PD. A total of 105 PD subjects were included and divided into anosmia and non-anosmic groups, using the University of Pennsylvania Smell Identification Test (UPSIT).

Objective: To clarify the association of anosmia or constipation with cognitive dysfunction and disease severity in patients with Parkinson's disease (PD).

Methods: Newly diagnosed patients with PD (less than 5 years) without a clinical diagnosis of dementia were included from February 2017 to August 2018. The subjects were further divided into subgroups based on whether anosmia occurred and the grade of constipation.

Aim: To explore the effect of home-based exercise on motor symptoms (MS), non-motor symptoms (NMS), and health-related quality of life (HRQOL) in Parkinson's disease (PD) patients.

Methods: This study was a randomized control trial with a convenience sample of 98 PD patients. Data were collected at baseline and interventions after 4 and 8 weeks.

Background: Peripheral nerve injuries result in muscle denervation and apoptosis of the involved muscle, which subsequently reduces mitochondrial content and causes muscle atrophy. The local injection of mitochondria has been suggested as a useful tool for restoring the function of injured nerves or the brain.

Objective: To determine outcomes following the administration of isolated mitochondria into denervated muscle after nerve injury that have not been investigated.

Background: This study aimed to clarify whether Parkinson's disease (PD) and depression were independent risk factors or with synergic effects in dementia.

Methods: Newly diagnosed PD ( = 1213) patients and control subjects ( = 4852) were selected from the Taiwan National Health Insurance Research Database from January 2001 through December 2008. Follow-up ended in 2011 with an outcome of dementia occurring or not.

A possible association between depression and either the severity of constipation or dysosmia in Parkinson's disease (PD) patients was investigated in this cross-sectional study. One-hundred six patients who had the history of PD for less than 5 years were recruited. Depression was measured using the Beck Depression Inventory-II (BDI-II), and our patients were divided into depressive and non-depressive groups (DP: BDI-II ≥ 14; n = 22 and NDP: BDI-II < 14; n = 84).

Background: Spinal epidural hematoma (SEH) after acupuncture is rare and may present with acute or subacute onset and varied symptoms, making it difficult to diagnose. This condition can mimic acute stroke, so it is vital to establish a clear diagnosis before considering thrombolytic therapy, which could be disastrous if applied inappropriately.

Case Report: We describe a 52-year-old man who presented to our emergency department (ED) with acute onset of unilateral weakness of the limbs for 3.
