Article Synopsis
  • Advance care planning (ACP) is crucial for palliative care, but documentation and discussions about it have been persistently low, highlighting the need for better family involvement in medical decisions.
  • This study evaluates a structured, family-supported ACP program for adult palliative care patients by comparing outcomes in a randomized controlled trial with patients receiving standard care.
  • The primary goal is to see how accurately families can predict patients' treatment preferences, with various secondary outcomes focused on communication, emotional well-being, and overall satisfaction with the intervention.

Article Synopsis
  • The study focused on primary progressive aphasia (PPA) in native Chinese speakers, highlighting the unique challenges posed by the classifier system in Chinese compared to Indo-European languages.
  • Results showed that both semantic variant (sv) PPA and logopenic variant (lv) PPA patients struggled significantly with classifier production, with lvPPA patients performing better in recognition tasks.
  • The findings indicate that classifier processing could serve as a linguistic marker for distinguishing between different PPA variants, with performance linked to specific brain regions involved in language and visual processing.

The number of patients with dementia grows rapidly as the global population ages, which posits tremendous health-care burden to the society. Only cholinesterase inhibitors and a N-methyl-D-aspartate receptor antagonist have been approved for treating patients with Alzheimer's disease (AD), and their clinical effects remained limited. Medical devices serve as an alternative therapeutic approach to modulating neural activities and enhancing cognitive function.

Chronic diseases often lead to metabolic disorders, causing anabolic resistance and increased energy consumption, which result in cachexia. Cachexia, in turn, can lead to major clinical consequences such as impaired quality of life, shortened life expectancy, and increased healthcare expenditure. Existing international diagnostic criteria for cachexia employ thresholds derived from Western populations, which may not apply to Asians due to differing body compositions.

Background And Objective: Recent advances have led to cure or long-term disease control for patients with hematological malignancy (HM). Unfortunately, some of them still have poor prognoses and are often associated with significant symptom burden and poor quality of life for patients and families. These patients usually require supportive care including red blood cell and platelet transfusion, due to disease itself and the oncological treatment, apart from their symptom management.

Advance care planning (ACP) facilitates individuals to proactively make decisions on their end-of-life care when they are mentally competent. It is highly relevant to older adults with frailty because they are more vulnerable to cognitive impairment, disabilities, and death. Despite devoting effort to promoting ACP among them, ACP and advance directive completion rates remain low.

Article Synopsis
  • * Researchers evaluated 40 PPA patients and 20 cognitively normal individuals through a Chinese dictation test (CLAP) and found that all PPA patients had significantly lower writing accuracy compared to controls, with no notable differences among the PPA variants.
  • * The test exhibited high sensitivity and specificity for identifying PPA in Chinese speakers, and specific types of writing errors were linked to different PPA variants, correlating with certain brain regions essential for language processing.

Purpose: CADASIL (cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy) is the most common cause of heritable vascular dementia. Recognizing the disease before the full-blown clinical features is challenging, so our case series high light clinical characteristics, screening tools and diagnostic process of the patients with CADASIL.

Case Report: Our case series reports neurocognitive features, neuroimaging, and exemplary pedigrees of seven patients with genetically confirmed CADASIL, in which six patients presented with dementia and the other one presented with migraine.

Background: The Dementia Knowledge Assessment Scale (DKAS) is a reliable and valid measurement of dementia knowledge for diverse allied health professionals but its traditional Chinese version has not been formally validated yet. The purpose of this study was to translate the DKAS from English to traditional Chinese and evaluate its psychometric properties among home care workers in Taiwan.

Methods: The DKAS scale was translated into traditional Chinese through a forward translation and back translation process following the cross-cultural translation guideline.

Background: Patients with acute myeloid leukaemia (AML) and myelodysplastic syndrome (MDS) suffer from a significant symptom burden and psychological, spiritual, social needs comparable to patients with solid metastatic malignancy. Referral to palliative care services for these haematological patients remains limited or often confined to the last days of life. We pioneered a palliative care (PC) program integrated with standard haematological care.

Article Synopsis
  • - The study aimed to explore the relationship between comorbidity and cognitive decline in older adults with mild to moderate dementia, using a prospective cohort design with 175 participants from Hualien Tzu Chi Hospital.
  • - Researchers assessed comorbidity using indices like CIRS-G, CCI, and MRCI, and cognitive function through tests like the MMSE and clock drawing test, discovering that osteoarthritis, hypertension, and hyperlipidemia were the most common comorbidities.
  • - Results showed that the severity index from CIRS-G was significantly linked to cognitive decline, while the other indices (CCI and MRCI) did not show a similar association, suggesting CIRS-G is more effective for measuring this

Atypical parkinsonism or atypical parkinsonian syndromes (APS) refer to a group of neurodegenerative disorders which mimic typical Parkinson's disease but poorly respond to levodopa treatment and deteriorate faster. APS are very rare and among them, progressive supranuclear palsy (PSP), multiple system atrophy (MSA), and corticobasal degeneration (CBD) are the three relatively better characterized entities. The prevalence estimates of PSP, MSA, or CBD are mostly <10/10, and the incidence estimates are around 1/10 person-year; both estimates remain stable over the past few decades.
