SPLP 5210 - Adult Cognitive- Communicative Disorders Introduction Course Introduction This course will emphasize: Brain vs. mind Cognitive-communicative disorders due to brain lesions Course Introduction Brain Mind Neuroanatomical lesion Cognitive-communicative Abrupt Lesion: Traumatic Brain Injury disorders Progressive Deterioration: Dementia Traumatic Brain Injury Introductory Concepts Incidence & Causes Cognition, Language, & Communication  Traumatic Brain Injury (TBI) Incidence ~ 500,000 cases/year in the U.S. Highest incidence Older adults and children under 5 Typically resulting from falls Adolescents and young adults Ages 15-24, typically from motor vehicle accidents >200,000 service members have been diagnosed with TBI since 2009 (Coelho [Ch. 7] in Johnson & Johnson, 2017) Cognitive and Communicative Complications 75% TBI cases are mild Mind vs. brain: What is cognition? Most common characteristic Information processing systems symptomatology of TBI is cognitive Stored knowledge disorders Cognition: Integrated systems that… Analyze sensation Detect and remember regularities in sensory information Integrate analyzed information with past experiences to guide behavior System integration depends on the stimulus Lexical item vs. Sentence vs. Narrative (Bayles et al., 2020; Coelho [Ch. 7] in Johnson & Johnson, 2017) Cognitive and Communicative Complications Cognitive Disturbances Orientation Awareness to person, time, and place Orientation Attention/Concentration Attention/Concentration Focused/selective, sustained, & alternating attention Memory Memory Reasoning Long, short, & working memory Executive functioning Reasoning Organization, associations (Coelho [Ch. 7] in Johnson & Johnson, 2017) Executive functioning Metacognition/self-regulation Most common dysfunction in TBI Cognitive and Communicative Complications If the cognitive disturbances below Expression and comprehension: occur in TBI, what are your guesses re: language and communication in the Lexical vs. Sentence vs. Narrative. person with TBI? Message Production Reception Orientation Attention/Concentration Memory Reasoning Executive functioning Most pronounced problem (Coelho [Ch. 7] in Johnson & Johnson, 2017) Cognitive and Communicative Complications Cognitive Disturbances Impact on Communication Confused Language Orientation Relevance Attention/Concentration Pragmatic consequences Memory Reasoning Impact on Daily Routines Executive functioning Planning Organization (Coelho [Ch. 7] in Johnson & Johnson, 2017) Completion  In-class Reading Johnson WD, Griswold DP.
