Diabetes Mellitus and Energy Dysmetabolism in Alzheimer's Disease: Understanding the Relationships and Potential Therapeutic Targets.

Over the last century, there has been a gradual but sustained increase in life expectancy globally. A consequence of increased life expectancy is an associated rise in the prevalence of agerelated chronic debilitating neurodegenerative disorders, such as Alzheimer's disease (AD), Parkinson's disease, Huntington's disease, and multiple sclerosis. These disorders, which are generally characterised by the loss of motor/sensory neurons and cognitive decline, have continued to confound researchers who are working tirelessly to define their pathogenetic mechanisms and develop effective therapies.

Substance use and substance use disorders in Africa: An epidemiological approach to the review of existing literature.

The relationship between man and substances that have abuse potentials, and whose use has been associated with the development or progression of substance use disorders has continued to evolve in terms of geography, economic implications, and time. History shows that local plants with psychoactive constituents can get exported worldwide through global travel, commerce, or even conquest. Time and globalization also change people's relationship with substances of abuse; hence, an area that was initially alien to certain substances might evolve to becoming a trafficking hub, and then a destination.

Microbiome-Based Therapies in Parkinson's Disease: Can Tuning the Microbiota Become a Viable Therapeutic Strategy?

Progressive neurodegenerative disorders such as Parkinson's disease (PD) have continued to baffle medical science, despite strides in the understanding of their pathology. The inability of currently available therapies to halt disease progression is a testament to an incomplete understanding of pathways crucial to disease initiation, progression and management. Science has continued to link the activities and equilibrium of the gut microbiome to the health and proper functioning of brain neurons.

Neuroinflammation and Oxidative Stress in Alzheimer's Disease; Can Nutraceuticals and Functional Foods Come to the Rescue?

Alzheimer's disease (AD), the most prevalent form of age-related dementia, is typified by progressive memory loss and spatial awareness with personality changes. The increasing socioeconomic burden associated with AD has made it a focus of extensive research. Ample scientific evidence supports the role of neuroinflammation and oxidative stress in AD pathophysiology, and there is increasing research into the possible role of anti-inflammatory and antioxidative agents as disease modifying therapies.

COVID-19, the Brain, and the Future: Is Infection by the Novel Coronavirus a Harbinger of Neurodegeneration?

However, there have been reports associating the influenza virus pandemic and long-term infection with the Japanese encephalitis virus with the development of post-encephalitic Parkinsonism or von Economo's encephalitis. In the last couple of years, there has been a worldwide pandemic caused by the novel coronavirus or severe acute respiratory syndrome coronavirus (SARS-CoV)-2, which causes a severe acute respiratory syndrome and is found to be associated with symptoms or complications of the central nervous system.

Nutrition, nutritional deficiencies, and schizophrenia: An association worthy of constant reassessment.

Schizophrenia is a mental health disorder that occurs worldwide, cutting across cultures, socioeconomic groups, and geographical barriers. Understanding the details of the neurochemical basis of schizophrenia, factors that contribute to it and possible measures for intervention are areas of ongoing research. However, what has become more evident is the fact that in targeting the neurochemical imbalances that may underlie schizophrenia, the type of response seen with currently available phamacotherapeutic agents does not provide all the answers that are needed.

Glutamate and depression: Reflecting a deepening knowledge of the gut and brain effects of a ubiquitous molecule.

The versatility of glutamate as the brain's foremost excitatory neurotransmitter and modulator of neurotransmission and function is considered common knowledge. Years of research have continued to uncover glutamate's effects and roles in several neurological and neuropsychiatric disorders, including depression. It had been considered that a deeper understanding of the roles of glutamate in depression might open a new door to understanding the pathological basis of the disorder, improve the approach to patient management, and lead to the development of newer drugs that may benefit more patients.

The potential toxicity of food-added sodium benzoate in mice is concentration-dependent.

However, there is insufficient information on the possible effects of dietary fortification with AA on the health of the brain.

Parkinson's Disease: Is there a Role for Dietary and Herbal Supplements?

Parkinson's Disease (PD) is characterised by degeneration of the neurons of the nigrostriatal dopaminergic pathway of the brain. The pharmacological cornerstone of PD management is mainly the use of dopamine precursors, dopamine receptor agonists, and agents that inhibit the biochemical degradation of dopamine. While these drugs initially provide relief to the symptoms and improve the quality of life of the patients, progression of the underlying pathological processes, such as oxidative stress and neuroinflammation (which have been strongly associated with PD and other neurodegenerative disorders), eventually reduce their benefits, making further benefits achievable, only at high doses due to which the magnitude and frequency of side-effects are amplified.
