Right Hemisphere Brain Disorder (RHBD)

Flashcards about Right Hemisphere Brain Disorder (RHBD).

Etiology of Right Hemisphere Brain Disorder (RHBD)

May result from stroke, trauma, brain tumor, or degenerative disease.

Characteristics Problems of RHD

Cognitive communication, anosognosia, left-sided neglect, orientation, attention, and organization.

Cognitive-Communication Impairments in RHBD

Limited social skills, difficulty grasping overall significance of events, understanding inferences, integrating verbal information, ignoring unneeded information, fixations on irrelevant details.

Affective Deficits in RHBD

Difficulty comprehending prosody, understanding emotional affect in others, flat affect, appearing distant, and monotone voice.

Areas SLPs are becoming more involved with in RHD

Visual spatial neglect, attention deficits, lack of facial expression, poor body language, prosody, memory, and executive functions.

Communication Difficulties in RHD

Difficulties using context cues to infer and difficulties getting the big picture. Idioms, sarcasm, and speaker's intent are often missed.

General Findings for RHD

The verbal deficits are extralinguistic and paralinguistic. 50% have communication deficits but not with phonology, morphology, syntax, or semantics.

Social Communication in RHD

Adequate superficial social communication, but deficits are most apparent in conversation and with more complex communication.

Selected Assessment Tools for Patients Presenting with RHD

RIC Evaluation of Communication Problems in Right Hemisphere Dysfunction-3 (RICE-3), Mini Inventory of Right Brain Injury (MIRBI), Ross Information Processing Assessment – 2, Burns Brief Inventory of Communication
