Brain Injury (Right Hemisphere) - Coggle Diagram
Brain Injury (Right Hemisphere)
Traumatic Brain Injury
External Forces
Motor vehicle accidents
Sports
Gunshot wounds
Fall
Abuse
Open head Injury
Results in focal damage
Penetrating injury
Closed head injury
Diffuse damage
Coup: brains primary point of contact
Contrecoupe: brain's secondary point of contact
Neuron damage from coup-contrecoup results in axon shearing
Brain Aging
Healthy aging
Language remains intact
Slight decline in word finding abilities
Syntactic complexity in discourse declines
Sustained attention remains intact during simple tasks
Mild Cognitive Impairment
Not within the normal spectrum but not severe enough to affect activity of daily living
May increase the risk of later progressing to dementia
May never get worse, can actually get better in some cases
Decreased sustained attention
Decreased word finding abilities
Decreased short term memory
Difficulty with executive functions
Difficulty following detailed heavy conversations/writings
No functional impairment
No significant impairment in social functioning
Major Neurocognitive Disorder (Dementia)
Progressive
Alzheimer's
Frontotemporal Degeneration
Lewy Body Disease
Potentially reversible/stoppable
Medically induced degeneration
Metabolic/Endocrine/Nutritional/Systematic
Vascular demntia/Hyrocephalus/Tumors/Hematoma
Right Hemisphere Language Disorders
Left Neglect: Failure to report/respond/orient towards stimuli contralateral to brain lesion
Anosognosia: Lack of knowledge/perception of a disease
Aprosodia: Impaired prosody abilities
Amusia: Impairment in recognition, production, or reproduction of music
Topographical Disorientation: Difficulty describing how to travel from one place to another, getting lost
Difficulty processing emotion and recognizing/using facial expressions, humor, and sarcasm
Disrupted content and organization of discourse: Comprehension, relevant information, pragmatics, literal interpretations, inferences
Alzheimer's Disease
Progressive and fatal disease
No known cure
Onset after age of 65
1/10 peoplle
Presence of neurofibrillary tangles, amyloid plaques, neuronal atrophy shrinkage of cortex and widening of ventricles
Stages: Language > problem solving > emotion > sensory > long term memory > balance > breathing and heart
8-10 year progression
