Parkinson's disease is a heterogenous neurodegenerative disorder with a wide variety of motor and non-motor symptoms. This study used resting-state fMRI to identify the neural substrates of PD and explore the acute neural response to acupuncture stimulation in 74 participants (50 patients with PD and 24 healthy controls). All participants with PD were evaluated for the severity of symptoms using the Unified Parkinson's Disease Rating Scale and Balance Master.

Background And Objective: Heart failure (HF) is associated with high mortality and hospitalization rates, and its prevalence increases with age. As congestion is the most common cause of hospitalization for HF, diuretics are the most prescribed drugs. However, these agents have side effects due to electrolyte imbalance.

Background: Heart failure (HF) is characterized by functional or structural dysfunction of the heart, resulting in impaired blood ejection or ventricular filling. Conventional Western Medicine (CWM) remains the mainstay of treatment for HF; however, the occurrence of adverse events (AEs) necessitates the exploration of alternative treatments. Herbal medicine and acupuncture are adjunctive therapies for HF and have shown potential for improving heart function.

Article Synopsis
  • The study examined the effects of Kami Guibi-tang, a therapeutic drug, on patients with cognitive decline, highlighting the need for further research as the number of such patients increases globally.
  • Conducted as a retrospective chart review at KyungHee University Hospital, it analyzed 31 patients who took Kami Guibi-tang for over 90 days, focusing on their scores from the Mini-Mental State Examination (MMSE-K) and Geriatric Depression Scale (S-GDS).
  • Results showed significant improvements in cognitive function measured by MMSE-K scores over time, particularly in the orientation and attention components, along with a notable decrease in depressive symptoms indicated by S-GDS scores.

Article Synopsis
  • Research shows that Chunghyul-dan (CHD), a herbal medicine, may help prevent strokes from recurring in patients with small vessel disease and potentially large artery issues as well.
  • A study was conducted involving 202 patients with ischemic stroke, where they were treated with 600 mg of CHD daily alongside other medications, and the recurrence of strokes was tracked over 2 years.
  • Findings indicated a low rate of stroke recurrence at 4.46%, with no negative side effects reported, suggesting that CHD could be effective across different stroke causes, but further research is needed through a randomized controlled trial.

Background: The incidence of insomnia increases with age and is related to cognitive function in older adults; therefore, it is important to manage it actively. In this study, we report a protocol for the evaluation of the efficacy and safety of Kami Guibi-tang (KGT), a herbal prescription that has been widely used in East Asia for insomnia, forgetfulness, and depression, in older adults with insomnia.

Methods: In this single-center, double-blind, randomized controlled trial, 60 older adults with insomnia and subjective cognitive decline will be recruited and randomly assigned to the KGT or placebo group.

Geopung-Chunghyuldan (GCD), which is a mixture of Chunghyuldan (CD), Radix Salviae Miltiorrhizae, Radix Notoginseng, and Borneolum Syntheticum, is used to treat ischemic stroke in traditional Korean medicine. This study aimed to investigate the effects of GCD and CD on ischemic brain damage using in vitro and in vivo stroke models, as well as to elucidate the synergistic effects of GCD against ischemic insult. To study the effect of GCD in an in vitro ischemia model, SH-SY5Y cells were exposed to oxygen-glucose deprivation (OGD).

Pain in Parkinson's disease (PD) represents a complex phenotype known to decrease quality of life. This pragmatic randomized, controlled clinical trial evaluated the efficacy of pharmacopuncture (PA) for improving pain symptoms and investigated the corresponding therapeutic mechanisms in patients with PD. Ninety patients with PD-related pain were randomly allocated to receive either PA, manual acupuncture, or usual care in a 1:1:1 ratio; sixty healthy controls were included for comparative analysis of brain imaging data.

Background: Kami Guibi-tang (KGT), a traditional Korean herbal medicine is mainly used to treat insomnia and nervousness. Acetylcholinesterase inhibitors (AChEIs) are the main treatments for mild Alzheimer's disease (AD), a degenerative brain disease. However, currently no drug can fundamentally treat AD or reverse the advanced cognitive decline.

Background: Vascular dementia (VaD) is the second most common type of dementia after Alzheimer's disease. Currently, no FDA-approved drugs are available for the treatment of VaD. Artemisia annua Linné (AA) is known to have antioxidant properties, but its effects and mechanisms of action on cognitive impairment are still unknown.

Background: Amnestic mild cognitive impairment (aMCI) is often considered a precursor to Alzheimer's disease (AD) and represents a key therapeutic target for early intervention of AD. However, no treatments have been approved for MCI at present. Our previous pilot study has shown that Kami Guibi-tang (KGT), a traditional herbal prescription widely used in Korean medicine for treating amnesia, might be beneficial for improving general cognitive function of aMCI patients.

Objectives: Parkinson's disease (PD) is a neurodegenerative disease in which patients are suffering various symptoms. Previous experimental studies suggested that herbal medicine Ukgansan (UGS) could be beneficial for PD. The aim of this pilot clinical trial was to evaluate the efficacy of UGS for improving clinical symptoms in patients with PD.

Article Synopsis
  • * A review of patient records from Kyung Hee University revealed that over 50% of 4,821 patients were treated for neurological disorders, with an overall average age of 54.62 years and a majority being women.
  • * The occurrence of adverse events was noted at 2.32%, mostly in older women, with patients recovering naturally and no lasting effects, suggesting that BVP is generally safe but calls for further research into its adverse effects and their connection to patient characteristics.

  • - Multiple sclerosis (MS) is a chronic disease affecting the central nervous system, with increasing prevalence and an unclear cause, often linked to autoimmune regulation issues; many patients seek alternative treatments due to the limited effectiveness of standard immunomodulatory therapies.
  • - A scoping review was conducted to assess the clinical evidence around East Asian herbal medicine for treating MS, examining articles published until 2019 across six databases, resulting in the inclusion of 14 relevant studies.
  • - Findings suggest that herbal medicines may improve MS symptoms and reduce recurrence, largely due to their potential effects on oxidative stress and inflammation, but overall evidence remains weak and necessitates further research for conclusive results.

Background: Mild cognitive impairment (MCI) is considered an intermediate phase between normal aging and dementia. As the majority of cases of amnestic MCI (aMCI) progress to Alzheimer's disease (AD), it is considered the prodromal stage of AD, and a treatment target for prevention of further cognitive decline. However, no medications have been shown to have symptomatic or preventive benefits in MCI.
