Exam 2: Neuroanatomy Part 2, deck 2 Flashcards
Why Talk About This Topic?—Disorders of Consciousness
◦ Voluntary = an act of the will
◦ Conscious = aware of self and others
◦ Motor act = movements of the body
So, consciousness is at the core of what we do every time we speak.
Core Consciousness
- Our sense of ourselves in the here and now
- Our sense of objects in the here and now
- Our sense of the relationship between these objects and ourselves.
Reticular Activating
System
RAS projects to the cerebral cortex.
Assessing Consciousness
Glasgow Coma Scale (GCS)
15-point scale that attempts to measure a
person’s level of consciousness
◦ 13 or greater = possible minor brain injury
◦ 9–12 = moderate brain injury
◦ Less than 9 = severe brain injury
◦ Less than 8 = coma.
Rancho Levels of Cognitive Functioning (RLCF)
8-level scale
- Tracks a person’s emergence from coma
- Level I = lowest level
- Level VIII = highest level
Two Other Conditions Related to Discussion of Conscious
- Out-of-body experiences (OBEs): sense of leaving one’s own body; loss of feeling of embodiment
- Near-death experiences (NDEs): elaborate
experiences with cognitive, affective,
paranormal, and transcendental elements.
SLP: Coma Stimulation
Systematic application of stimulation to a
person’s five senses
◦ Vision
◦ Hearing
◦ Smell
◦ Taste
◦ Touch
Purpose: to speed emergence from coma.
What Are Executive
Functions?
Cognitive functions that order and manage all other cognitive functions (e.g., attention, memory) for the purpose of setting and attaining goals.
What Is Attention?
A person’s ability to focus (i.e., focused
attention) on a stimulus in the environment.
What Is Memory?
The storage of information
◦ Working memory: space for manipulation
◦ Short-term memory: time in seconds
◦ Long-term memory: time in days to years.
Treating Memory:
The 4 Rules of Memory
- Rule #1: You cannot remember what you
do not pay attention to. - Rule #2: You cannot remember (in the
long term) what you do not understand. - Rule #3: You must practice memory when
the outcome is not apparent (e.g.,
practicing piano). - Rule #4: Memory is an active process; you
must actively manipulate it to store it.
Treating Memory:
Internal Memory Strategies
- Repetition (neuroplasticity – repetition matters!)
- Visualization (visualize notes; turn info. into story)
- Association (mnemonics)
- Grouping (place like items together)
- Writing it down (physical writing improves memory)
Treating Memory:
External Memory Strategies
- Calendars
- To-do lists
- Journals
- Electronic organization
- Electronic reminders
