Background: Alzheimer's dementia is the most common dementia. However, recently, choline alfoscerate is prescribed for treating Alzheimer's dementia, although it is not a treatment for this disease. Purpose: To analyze the prescription patterns of choline alfoscerate as a dementia treatment for patients with Alzheimer's disease and to analyze, as well as the factors affecting choline alfoscerate prescription. Method: The 2016 HIRA-NPS data was used in this study. The code of Alzheimer's dementia is F00 in the ICD-10 disease classification code. We analyzed the demographic, clinical, and regional characteristics associated with donepezil, rivastigmine, galantamine, memantine, and choline alfoscerate prescriptions. All statistical and data analyse were conducted by SAS 9.4 and Excel. Results: For patients with Alzheimer's disease, choline alfoscerate was the second most prescribed after donepezil. Analysis results showed that choline alfoscerate was more likely to be prescribed to men than to women, and more likely to be prescribed by local health centers than by medical institutions. Moreover, choline alfoscerate was highly likely to be prescribed at neurosurgical departments, among medical departments. Conclusions: This study confirmed that choline alfoscerate was prescribed considerably for patients with Alzheimer's dementia. Further studies valuating its clinical validity should be performed to clarify whether choline alfoscerate prescription is appropriate for treating Alzheimer's dementia.

Objective : Isoflurane, a widely used common inhalational anesthetic agent, can induce brain toxicity. The challenge lies in protecting neurologically compromised patients from neurotoxic anesthetics. Choline alfoscerate (L-α-Glycerophosphorylcholine, α-GPC) is recognized for its neuroprotective properties against oxidative stress and inflammation, but its optimal therapeutic window and indications are still under investigation. This study explores the impact of α-GPC on human astrocytes, the most abundant cells in the brain that protect against oxidative stress, under isoflurane exposure. Methods : This study was designed to examine changes in factors related to isoflurane-induced toxicity following α-GPC administration. Primary human astrocytes were pretreated with varying doses of α-GPC (ranging from 0.1 to 10.0 µM) for 24 hours prior to 2.5% isoflurane exposure. In vitro analysis of cell morphology, water-soluble tetrazolium salt-1 assay, quantitative real-time polymerase chain reaction, proteome profiler array, and transcriptome sequencing were conducted. Results : A significant morphological damage to human astrocytes was observed in the group that had been pretreated with 10.0 mM of α-GPC and exposed to 2.5% isoflurane. A decrease in cell viability was identified in the group pretreated with 10.0 µM of α-GPC and exposed to 2.5% isoflurane compared to the group exposed only to 2.5% isoflurane. Quantitative real-time polymerase chain reaction revealed that mRNA expression of heme-oxygenase 1 and hypoxia-inducible factor-1α, which were reduced by isoflurane, was further suppressed by 10.0 µM α-GPC pretreatment. The proteome profiler array demonstrated that α-GPC pretreatment influenced a variety of factors associated with apoptosis induced by oxidative stress. Additionally, transcriptome sequencing identified pathways significantly related to changes in isoflurane-induced toxicity caused by α-GPC pretreatment. Conclusion : The findings suggest that α-GPC pretreatment could potentially enhance the vulnerability of primary human astrocytes to isoflurane-induced toxicity by diminishing the expression of antioxidant factors, potentially leading to amplified cell damage.

Injection lipolysis or mesotherapy gained popularity for local fat dissolve as an alternative to surgical liposuction. Phosphatidylcholine (PPC) and aminophyl-line (AMPL) are commonly used compounds for mesotherapy, but their efficacy and safety as lipolytic agents have been controversial. Glycerophosphocholine (GPC) is a choline precursor structurally similar to PPC, and thus introduced in aesthetics as an alternative for PPC. This study aimed to evaluate the effects of GPC on adipocytes differentiation and lipolysis and compared those effects with PPC and AMPL using in vitro and in vivo models. Adipogenesis in 3T3-L1 was measured by Oil Red O staining. Lipolysis was assessed by measuring the amount of glycerol released in the culture media. To evaluate the lipolytic activity of GPC on a physiological condition, GPC was subcutaneously injected to one side of inguinal fat pads for 3 days. Lipolytic activity of GPC was assessed by hematoxylin and eosin staining in adipose tissue. GPC significantly suppressed adipocyte differentiation of 3T3-L1 in a concentration-dependent manner (22.3% inhibition at 4 mM of GPC compared to control). Moreover, when lipolysis was assessed by glycerol release in 3T3-L1 adipocytes, 6 mM of GPC stimulated glycerol release by two-fold over control. Subcutaneous injection of GPC into the inguinal fat pad of mice significantly reduced the mass of fat pad and the size of adipocytes of injected site, and these effects of GPC were more prominent over PPC and AMPL. Taken together, these results suggest that GPC is the potential therapeutic agent as a local fat reducer.

Dementia is a clinical syndrome characterized by a cluster of symptoms and signs that manifest as difficulties in cognitive functions such as memory, psychological and psychiatric changes, and impairments in activities of daily living. As a result of worldwide trends of population aging, dementia has had a huge impact on public health in almost all countries. Disease modification therapies for dementia have not yet been developed. However, pharmacotherapy is essential in patients with dementia to combat delays in their cognitive and functional decline. In this article, we review the current pharmacotherapy for dementia. Three acetylcholinesterase inhibitors-donepezil, rivastigmine, galantamine-and memantine are the only medications that have been approved for the treatment of dementia. We present the indications, dose recommendations, side effects, and criteria for National Health Insurance coverage in Korea of these medications for dementia treatment. Although the Ministry of Food and Drug Safety in Korea has not approved any medications for managing the behavioral and psychological symptoms of dementia, some antipsychotics and antidepressants have been studied and used clinically for those purposes. Clinicians may consider vitamin E, Ginkgo biloba extract, choline alfoscerate, or omega-3 fatty acids as additional treatment options. Non-steroid anti-inflammatory drugs, estrogen hormone therapy, and statins are not generally recommended for dementia treatment. We believe that our findings will aid clinicians in the treatment of patients with cognitive decline.
