Age Related Cognitive Decline

The population of older adults is rapidly increasing, as is the number and type of products and interventions proposed to prevent or reduce the risk of age-related cognitive decline. Advocacy and prevention are part of the American Speech-Language-Hearing Association’s (ASHA’s) scope of practice documents, and speech-language pathologists must have basic awareness of the evidence contributing to healthy cognitive aging. In this article, we provide a brief overview outlining the evidence on activity engagement and its effects on cognition in older adults. We explore the current evidence around the activities of eating and drinking with a discussion on the potential benefits of omega-3 fatty acids, polyphenols, alcohol, and coffee. We investigate the evidence on the hypothesized neuroprotective effects of social activity, the evidence on computerized cognitive training, and the emerging behavioral and neuroimaging evidence on physical activity. We conclude that actively aging using a combination of several strategies may be our best line of defense against cognitive decline.

Novel Drugs

Recently, research and development in the field of drug delivery systems (DDS) facilitating site-specific therapy has reached significant progression. DDS based on polymer micelles, coated micro- and nanoparticles, and various prodrug systems including water-soluble polymer have been prepared and extensively studied as novel drugs designed for cancer chemotherapy and brain delivery. Since polymers are going to be used in human, this study has the interest of testing two types of polymer, polyimides (PI) and polyphenylenevinylene (PPV) on neuronal cells. The objective of this study was to determine the possible neurotoxicity and potential neuroprotective effects of PI and PPV towards SH-SY5Y neuronal cells challenged by hydrogen peroxide (H2O2) as an oxidant. Cells were pretreated with either PI or PPV for 1 hour followed by incubation for 24 hour with 100 µM of H2O2. MTS assay was used to assess cell viability. Results show that PI and PPV are not harmful within the concentration up to 10 µM and 100 µM, respectively. However, PI and PPV do not protect neuronal cells against toxicity induced by H2O2 or further up the cell death.

Nutritional Factors

The objective of this study was to conduct a review about the nutritional aspects and their influences on the pathophysiology of Alzheimer’s disease. The review describes the pathophysiology of Alzheimer’s disease, the generally indicated diets, and the nutritional factors that may aggravate the disease based on a literature review using the following keywords in English and Portuguese: “Alzheimer’s disease”, “physiopathology”, “nutritional aspects”, and “antioxidants”. A total of 100 articles were found, 48 in Lilacs and 52 in MedLine, but only 54 articles were selected for the review. The use of antioxidants as free radical scavengers is generally indicated in diets for Alzheimer’s patients. Studies also suggest that caffeine, vitamin B12, and folic acid have neuroprotective effects. Cohort studies found that a high intake of saturated fatty acids and obesity increase the risk of Alzheimer’s disease. People with Alzheimer’s disease should avoid diets high in carbohydrates and saturated fats, and prefer foods high in antioxidants.Keywords: Alzheimer disease; Antioxidants; Neurophysiology; Review literture as topic.
