Thanks to breakthroughs in diagnostic techniques and criteria, people with MS can now be detected earlier in their illness courses. In addition, the number, efficacy, and risk of MS treatments have all increased dramatically. A diagnosis of 'pre-symptomatic MS' is now possible, which could lead to the exploration of new preventive medicines 70 , Symptoms can be decreased, and the immune system can be improved with a doctor and a complete and effective treatment. Polyphenols are one of the therapeutically helpful chemicals for MS treatment. Resveratrol, quercetin, epigallocatechingallate, and myricetin are some of the polyphenols utilized for MS treatment due to their advantages and efficacy. Polyphenols are examined according to many models for MS treatment by reducing inflammation and breaking the immune system. Polyphenols demonstrated to be able to reduce inflammation by modifying the cytokine pathways in various studies for example, IL-β and TNF-α. In this method, brain demyelination is reduced, and normal limb function is restored. Polyphenols can be utilized in age-related MS and amyotrophic lateral sclerosis as prophylactics, keeping their effectiveness in mind 72 - Polyphenols are highly effective in both therapeutic and pharmacological settings. They can be found in a wide range of fruits and dietary meals. Various polyphenols have been studied for their impact on neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis. Neurodegenerative diseases are driven by inflammation, oxidative stress, and abnormal mitochondrial function, according to new research. For the treatment and prevention of many disorders, new therapeutic approaches that target specific genes and proteins are required. Inflammation, ion channels, reactive oxygen species ROS , and neurotransmitters are all controlled and regulated by polyphenols. Antioxidant capabilities are found in polyphenols. Neuroprotective effects are found in polyphenols, including EGCG, resveratrol, and quercetin. Polyphenols have been shown to activate antioxidant pathways such as Nrf2 in numerous studies. Polyphenols can also block the NFB and STAT signaling pathways. Polyphenols control the immune response by inhibiting proinflammatory cytokines, including TNF-α and IFN-γ. Polyphenols do, in fact, provide neuronal damage prevention. Duraes F, Pinto M, Sousa E. Old drugs as new treatments for neurodegenerative diseases. Pharmaceuticals Basel.

Their short-term memories, spatial visualisations, processing speeds, and language skills, were assessed over 2 months by cognitive tests computer programs. The dietary OPLE showed neuroprotection in nitric oxide-deficient rats. The mechanisms involved systemic and cellular modulations that eventually enhance neuron survival. The longer the duration of OPLE consumption, the more significant was the enhancement, as shown for short-term memory. |
| Introduction | Out of compounds that showed variable degrees of neuroprotection, nine were related to epicatechin, a monomeric flavonoid found in cocoa and green tea leaves that readily crosses the blood-brain barrier. Hence, catechin, epicatechin, and the related compound, epigallocatechin gallate EGCG were further screened for their neuroprotective properties against HIV proteins Tat and gp, and compared to those of resveratrol. Epicatechin and EGCG targets the brain-derived neurotrophic factor BDNF and its precursor proBDNF signaling pathways, normalizing both Tat-mediated increases in proapoptotic proBDNF and concomitant Tat-mediated decreases in the mature BDNF protein in hippocampal neurons. Epicatechin and epigallocatechin gallate were more potent than catechin or resveratrol as neuroprotectants. Due to its simpler structure and more efficient blood-brain barrier penetration properties, epicatechin might be the best therapeutic candidate for neurodegenerative diseases including HIV-associated neurocognitive disorders where oxidative stress is an important pathophysiological mechanism.

Abstract Neurodegeneration in Parkinson's, Alzheimer's, and other neurodegenerative diseases seems to be multifactorial, in that a complex set of toxic reactions including inflammation, glutamatergic neurotoxicity, increases in iron and nitric oxide, depletion of endogenous antioxidants, reduced expression of trophic factors, dysfunction of the ubiquitin-proteasome system, and expression of proapoptotic proteins leads to the demise of neurons.
Thus, the fundamental objective in neurodegeneration and neuroprotection research is to determine which of these factors constitutes the primary event, the sequence in which these events occur, and whether they act in concurrence in the pathogenic process. This has led to the current notion that drugs directed against a single target will be ineffective and rather a single drug or cocktail of drugs with pluripharmacological properties may be more suitable.
Green tea catechin polyphenols, formerly thought to be simple radical scavengers, are now considered to invoke a spectrum of cellular mechanisms of action related to their neuroprotective activity.
