Parkinson's: Vitamin B-3 may stop brain cell death

A Parkinson's study using human cells and a fly model found that a form of vitamin B-3 prevented the death of brain cells by preserving their mitochondria.

Abstract Because the brain is the most important human organ, many brain disorders can cause severe symptoms. For example, glioma, one type of brain tumor, is progressive and lethal, while neurodegenerative diseases cause severe disability. Nevertheless, medical treatment for brain diseases remains unsatisfactory, and therefore innovative therapies are desired. However, the development of therapies to treat some cerebral diseases is difficult because the blood-brain barrier (BBB) or blood-brain tumor barrier prevents drugs from entering the brain. Hence, drug delivery system (DDS) strategies are required to delive...

In this study we aimed to determine prevalence of dysphagia in Parkinson's disease and other Parkinson plus syndromes; to correlate it with severity of underlying illness and to determine the factors predicting dysphagia in patients of Parkinson's disease. Methods: It was a prospective observational study performed over 18 months in the neurology clinic of tertiary care public teaching hospital in Mumbai. All patients of Parkinson's disease (PD) diagnosed by UKPDS criteria and all patients of Parkinson-plus syndromes diagnosed clinically were included in the study serially. Patients with cognitive dysfunction (MMSE

The common neurodegenerative conditions are associated with various different forms of protein aggregation; a few proteins in the body have toxic alternative forms that can spread and cause harm to cells. Alzheimer's disease is associated with amyloid-β and tau, Parkinson's disease with α-synuclein, and so forth. But the decay of the aging brain is not a nice neat process in which one individual exhibits one clear-cut pathology with clear-cut symptoms indicative of that pathology. All protein aggregates occur in every aged person to some degree, and they interact with one another, alongside other mechanisms such...

Conclusion: This work shows that 18F-IAM6067 is a specific and selective S1R radiotracer. The absence or small changes in S1R detected here in animal models and human tissue warrants further investigations and suggests that S1R might not be the anticipated ideal biomarker for neuronal loss in neurodegenerative diseases such as AD and PD.

Conclusion: This meta-analysis suggests that exenatide use is associated with the alleviation of cognitive, motor and nonmotor symptoms. However, long-term studies with a large sample size of patients with PD of varying severity are required.
