The outcome and burden of Chinese patients with neurodegenerative diseases: A 10-year clinical feature study

Use of the QuickSort with older adults whose lifestyle decision-making capacity is being questioned

OBJECTIVES

Cognitive impairment affects older adults' capacity to live independently and make lifestyle decisions (lifestyle decision-making capacity; LS-DMC). Cognitive screens and clinical interviews are often used to assess people's need for living-supports prior to conducting comprehensive LS-DMC assessments in busy clinical settings. This study investigated whether the QuickSort - a brief new cognitive screen - provides efficient and accurate information regarding patients' LS-DMC when initially interviewed.

METHODS

This is an observational and diagnostic accuracy study of older inpatients (≥60 years) consecutively referred for neuropsychological assessment of LS-DMC (n = 124). The resources required by inpatients with questionable LS-DMC were quantified (length of hospital stay, living-supports). QuickSort scores, patient background information, and two common cognitive screens were used to differentiate between older inpatients (n = 124) who lacked (64%)/did not-lack (36%) LS-DMC.

RESULTS

Hospitalizations averaged 49 days, with 62% of inpatients being readmitted within one year. The QuickSort differentiated between those lacking/not-lacking LS-DMC better than two common cognitive screens and patient information. The likelihood that inpatients lacked LS-DMC increased by a factor of 65.26 for QuickSort scores <2 and reduced by a factor of 0.32 for scores ≥13. Modeling revealed that the post-test likelihood of lacking LS-DMC increased to 99% (scores <2) and reduced to 30% (scores ≥ 13) in settings where many inpatients lack LS-DMC.

CONCLUSIONS

Older adult inpatients with questionable LS-DMC have a high risk of extended hospitalization and readmission. The QuickSort provides time-efficient and sensitive information regarding patients' LS-DMC, making it a viable alternative to longer cognitive screens that are used at the initial interview stage.

Neuroprotective Role of Polyphenols in Treatment of Neurological Disorders: A Review

: The most frequent illnesses characterized by the gradual malfunctioning of brain neurons are neurodegenerative disorders (NDs). Genetic mutations and a range of biological processes can produce NDs. Alzheimer's disease (AD), Parkinson's disease (PD), and Multiple Sclerosis (MS) are all related to oxidative stress (OS). Reduced brain activity has become a greater health threat with a growing elderly population. It causes some pathophysiological alterations and is an important risk factor for a range of neurodegenerative illnesses. An increase in reactive oxygen species (ROS) can cause neuronal cell death, and it is thus essential to control ROS levels to maintain normal neuronal activity. Synthetic medicines are often used to treat neurological disorders; however, harmful effects have been reported. Multiple bodies of research have shown the effectiveness of polyphenols in the treatment of various NDs due to their negligible side effects. This review article describes the neuroprotection effects of polyphenols such as resveratrol, epigallocatechin-3-gallate, curcumin, and quercetin, as well as the signaling pathways and immune response controls through polyphenols.
