The inherent limitations of genetic analysis in humans and other mammals as well as striking conservation of most genes controlling nervous system functioning in flies and mammals made Drosophila an attractive model to investigate various aspects of brain diseases. Since RNA research has made great progress in recent years here we present an overview of studies demonstrating the role of various non‐coding RNAs in neurodegeneration and stress response in Drosophila as a model organism. We put special emphasis on the role of non‐coding micro RNAs, hsr‐omega transcripts, and artificial small highly structured RNAs as triggers of neuropathology including aggregates formation, cognitive abnormalities and other symptoms. Cellular stress is a conspicuous feature of many neurodegenerative diseases and the production of specialized proteins protects the nerve cells against aggregates formation. Therefore, herein we describe some data implicating various classes of non‐coding RNAs in stress response in Drosophila . All these findings highlight Drosophila as an important model system to investigate various brain diseases potentially mediated by some non‐coding RNAs including polyglutamine diseases, Alzheimer's disease, Huntigton's disease, and many others.
