With stuttering’s vast spectrum of different factors and forms, this review paper focuses on the impact of genetic, neurobiological, and psychological factors on this phenomenon, with varying brain activity among stutterers. With respect to the types of disfluencies, their frequencies, and patterns, this paper examines their developmental, neurogenic, and psychogenic aspects. The causes of stuttering, encompassing genetic factors and neurobiological effects, are explored with an emphasis on the role of non-coding regions in DNA. The implications of neuroimaging technologies display altered patterns within the neural circuitry associated with speech production and motor control, and highlight the impact of emotional stress on brain regions. Exploring family heredity with a specific focus on twins investigates the role of specific genes that influence speech development and contribute to stuttering. Presenting a review of the current literature on neuroimaging, genomic, and brain studies, this paper aims to contribute to a broader spectrum of other speech disorders, overall raising awareness of stuttering among both professionals and the public. This paper aims to deliver a deeper understanding of a topic that is not as researched as others and sheds light on the various components that affect stuttering in many ways.
