Introduction: Clinical practice shows that right-hemisphere cerebral strokes are often accompanied by one speech disorder or another. Objective: To find out Speech difficulties following a stroke in right hemisphere in brain. Methods: 101 individuals with dysarthria following stroke with mean age of 42.5 years participated in the study. Presence of stroke was confirmed by medical professional based on CT and MRI along with clinical evaluation. Perceptual assessment of speech was carried out and participants were classified into different dysarthria types based on Mayo clinic system by an SLP followed by assessment of speech intelligibility and global dysarthria severity. Results: The aim of the study 101 patient’s analyzed Speech difficulties following a stroke in right hemisphere in brain. Questions of the lateralization of speech functions are discussed, with particular reference to the role of the right hemisphere in speech activity and the structure of speech pathology in right-hemisphere foci. Clinical variants of speech disorders, such as aphasia, dysprosody, dysarthria, mutism, and stutter are discussed in detail. Conclusion: Types of speech disorders are also discussed, along with the possible mechanisms of their formation depending on the locations of lesions in the axis of the brain (cortex, sub-cortical structures, stem, and cerebellum) and focus size.
