The Efficacy of General Practitioner Assessment of Cognition in Chinese Elders Aged 80 and Older.

Objectives: This study examined the efficacy of the General Practitioner Assessment of Cognition-Chinese version (GPCOG-C) in screening dementia and mild cognitive impairment (MCI) among older Chinese.

Methods: Survey questionnaires were administered to 293 participants aged 80 or above from a university hospital in mainland China. Alzheimer disease and MCI were diagnosed in light of the National Institute on Aging and the Alzheimer's Association (NIA/AA) criteria.

MicroRNA-26a/Death-Associated Protein Kinase 1 Signaling Induces Synucleinopathy and Dopaminergic Neuron Degeneration in Parkinson's Disease.

Background: Death-associated protein kinase 1 (DAPK1) is a widely distributed serine/threonine kinase that is critical for cell death in multiple neurological disorders, including Alzheimer's disease and stroke. However, little is known about the role of DAPK1 in the pathogenesis of Parkinson's disease (PD), the second most common neurodegenerative disorder.

Methods: We used Western blot and immunohistochemistry to evaluate the alteration of DAPK1.

1,5-dicaffeoylquinic acid protects primary neurons from amyloid β 1-42-induced apoptosis via PI3K/Akt signaling pathway.

Background: Recently, 1,5-dicaffeoylquinic acid (1,5-DQA), a caffeoylquinic acid derivative isolated from Aster scaber, was found to have neuroprotective effects. However, the protective mechanisms of 1,5-DQA have not yet been clearly identified. The purpose of this study was to explore the protective mechanisms of 1,5-DQA on neuronal culture.

alpha-Synuclein redistributed and aggregated in rotenone-induced Parkinson's disease rats.

Objective To observe the influence of rotenone on the distribution of alpha-synuclein (ASN) in rat model of Parkinson's disease (PD). Methods Wistar rats were randomly divided into two groups and received 2 mg/kg rotenone (s.c.
