Preventive and therapeutic potential of ascorbic acid in neurodegenerative diseases.

Preventive and therapeutic potential of ascorbic acid in neurodegenerative diseases. CNS Neurosci Ther. 2017 Oct 04;: Authors: Moretti M, Fraga DB, Rodrigues ALS Abstract In this review, we summarize the involvement of ascorbic acid in neurodegenerative diseases by presenting available evidence on the behavioral and biochemical effects of this compound in animal models of neurodegeneration as well as the use of ascorbic acid as a therapeutic approach to alleviate neurodegenerative progression in clinical studies. Ascorbate, a reduced form of vitamin C, has gained interest for its multiple functions and mechanisms of action, contributing to the homeostasis of normal tissues and organs as well as to tissue regeneration. In the brain, ascorbate exerts neuromodulatory functions and scavenges reactive oxygen species generated during synaptic activity and neuronal metabolism. These are important properties as redox imbalance and abnormal protein aggregation constitute central mechanisms implicated in the pathogenesis of neurodegenerative diseases, including Alzheimer's, Parkinson's, and Huntington's diseases, multiple sclerosis, and amyotrophic lateral sclerosis. Indeed, several studies have indicated an association between low serum ascorbate concentrations and neurodegeneration. Moreover, ascorbic acid is a suitable candidate for supplying either antioxidant defense or modulation of neuronal and astrocytic metabolism under neurodegenerative conditions. Ascor...

"Understanding the Role of Hypoxia inducible factor during neurodegeneration for new therapeutics opportunities". Curr Neuropharmacol. 2018 Jan 10;: Authors: Merelli A, Rodriguez JCG, Folch J, Regueiro MR, Camins A, Alberto L Abstract Neurodegeneration (NDG) is linked with the progressive loss of neural function with intellectual and/or motor impairment. Several diseases affecting older individuals, including Alzheimer's disease, Amyotrophic Lateral Sclerosis, Huntington's disease, Parkinson's disease, stroke, Multiple Sclerosis and many others, are the most relevant disorders associated wit...

Of these, neurodegenerative diseases are usually characterised by onset in late adulthood, progressive clinical course, and neuronal loss with regional specificity in the central nervous system. They include Alzheimer's disease and other less frequent dementias, brain cancer, degenerative nerve diseases, encephalitis, epilepsy, geneti...

Abstract Caffeine is one of the most consumed stimulant of the central nervous system. Similar to those of other stimulants, its effects are to improve brain activity and stimulate cognition learning and memory. Caffeine affects the brain by acting mainly as a non-selective blocker of the adenosine receptors (A1, A2A, A2B, and A3). The purpose of this review article is to provide an overview on the neurobiochemical impact of caffeine, focusing on the ability of the drug to effectively counteract several neurodegenerative disorders such as Alzheimer's, Parkinson's, Huntington's diseases, Multiple sclerosis and Amyo...

s AKS Abstract Adenosine monophosphate-activated protein kinase (AMPK) is an evolutionarily conserved sensor of cellular energy status and has been reported to be involved in chronic inflammatory disorders. AMPK is expressed in immune cells, such as dendritic cells, macrophages, lymphocytes and neutrophils, and is an important regulator of inflammatory responses through the regulation of complex signaling networks in part by inhibiting downstream cascade pathways, such as nuclear factor kB, which is a key regulator of innate immunity and inflammation, as well as acting as a negative regulator of toll-like receptor...

CONCLUSIONS: Pre-clinical evidence largely shows that CBD can produce beneficial effects in AD, PD and MS patients, but its employment for these disorders needs further confirmation from well designed clinical studies. CBD pre-clinical demonstration of antiepileptic activity is supported by recent clinical studies in human epileptic subjects resistant to standard antiepileptic drugs showing its potential use in children and young adults affected by refractory epilepsy. Evidence for use of CBD in PD is still not supported by sufficient data whereas only a few studies including a small number of patients are available. ...

Caring for a person with a neurodegenerative disease (eg, Alzheimer disease, Parkinson disease, multiple sclerosis, amyotrophic lateral sclerosis, Huntington disease) can be extremely challenging.1 The challenges grow as the disease gets worse. If you are a caregiver of a person with a neurodegenerative disease, there are steps you may need to consider to decrease the risk or amount of caregiver burnout. This may help maintain or improve your health and wellness. It is important for you to know if you have caregiver burnout, or the common triggers that may cause your burnout.

Astrocytes are an important class of support cell in the brain, and one of the most common cell types in brain tissue. They carry out a wide range of tasks, most of which are absolutely essential to the functions performed by neurons. A few years ago, researchers suggested that senescent astrocytes may be responsible for a sizable portion of the progression of neurodegenerative conditions, a proposal expanded and further investigated since then, with a great deal more evidence gathered. Astrocyte behavior in the brain appears to change for the worse with age in a number of ways, not all of which may be connected to cellula...

Abstract The maintenance of health requires successful cell functioning which in turn depends upon the proper and active conformation of proteins besides other biomolecules. However, occasionally these proteins may misfold and lead to the appearance and progression of protein conformational diseases. These diseases apart from others include several neurodegenerative disorders (NDDs) such as Alzheimer's disease, Parkinson's disease, Huntington disease, multiple sclerosis, amyotrophic lateral sclerosis, and other less well known diseases. Although much knowledge has been gained, these NDDs still warrant advance...
