Damage to the right cerebral hemisphere (RHD) may cause a variety of disorders involving communication, attention, and executive functions. Disorders commonly associated with RHD include impairments in attention, including visuospatial neglect; cognitive deficits apparent primarily in executive function and awareness; reduced use and production of prosody; and difficulties with effective and efficient communication. This chapter focuses on disorders of communication, including theoretical underpinnings of those disorders, and suggestions for intervention. Several themes have surfaced in the understanding of communication disorders associated with RHD. Assessment of communication disorders associated with RHD typically involves observation, informal testing, and formal measures. While adults with RHD can have inefficiencies in semantic processing, behaviorally the deficits appear as difficulties with comprehension of discourse, inefficient or disorganized discourse production, misinterpretation of intended meaning, and difficulty producing or interpreting prosody, facial expression and other nonverbal cues.
