RESUMEN
Despite extensive research over the last few decades, the etiology of schizophrenia (SZ) remains unclear. SZ is a pathological disorder that is highly debilitating and deeply affects the lifestyle and minds of those affected. Several factors (one or in combination) have been reported as contributors to SZ pathogenesis, including neurodevelopmental, environmental, genetic and epigenetic factors. Deoxyribonucleic acid (DNA) methylation and post-translational modification (PTM) of histone proteins are potentially contributing epigenetic processes involved in transcriptional activity, chromatin folding, cell division and apoptotic processes, and DNA damage and repair. After establishing a summary of epigenetic processes in the context of schizophrenia, this review aims to highlight the current understanding of the role of DNA methylation and histone PTMs in this disorder and their potential roles in schizophrenia pathophysiology and pathogenesis.

With a constantly growing elderly population worldwide, a focus on developing efficient prevention and therapy for Alzheimer's disease (AD) seems timely and topical. Emphasis on natural medicine is increasingly popular in the search for drug candidates that are capable of preventing and treating AD related pathology, particularly where suppression of amyloid accumulation, neurofibrillary tangle formation, neuroinflammation and oxidative stress are equally significant. A number of phytochemical compounds have been shown to collectively reduce these AD hallmarks with the progression of natural drug candidates into human clinical trials. This review focuses on current research surrounding the therapies emerging within natural medicines and their related therapeutic potential for AD treatment.
