Right Hemisphere Disorder (RHD)
Understanding Right Hemisphere Disorder
Right Hemisphere Disorder occurs when an injury—such as a stroke, traumatic brain injury, tumor, or infection—affects the right side of the brain. While the left side of the brain typically handles literal language and logic, the right side manages complex "big picture" thinking and social communication.
Because the right side of the brain also helps with self-awareness, many people with RHD may not realize they are experiencing any difficulties.
Common Symptoms and Challenges
RHD can affect how a person thinks, acts, and perceives the world. Common signs include:
Attention & Focus: Difficulty staying on task or becoming easily distracted.
Left-Side Neglect: A lack of awareness of anything on the left side. This might mean ignoring food on the left side of a plate or failing to see people standing to their left.
Social & Communication Skills: Problems understanding humor, sarcasm, or non-verbal cues like facial expressions. The person may also struggle to stay on topic or take turns in conversation.
Memory: Trouble recalling past events or learning new information.
Organization & Planning: Difficulty arranging thoughts logically, following multi-step directions, or managing a daily schedule.
Problem Solving: A reduced ability to identify risks or solve everyday issues, such as knowing when to refill a prescription.
How Speech-Language Pathologists (SLPs) Help
An SLP will evaluate the individual’s communication and cognitive skills to create a personalized recovery plan. Treatment focuses on:
Building Awareness: Helping the individual recognize their challenges.
Developing Strategies: Using tools like calendars, checklists, and routines to manage memory and organization.
Improving Safety: Identifying ways to navigate the home and community securely.
