Study Notes
Neurological Tests
- Progressive loss of function in nerves and brain may result from various factors, including anoxia.
- Anoxia refers to the lack of oxygen to the brain, often associated with cardiac arrest due to blood flow stoppage.
- Sensory and reflex testing are critical in assessing neurological function.
- Neurological injuries can result from cerebrovascular disease (CVD), carbon monoxide poisoning, or trauma.
RLA Levels
- RLA Level 2: Generalized Response - Patients exhibit basic reflexes.
- RLA Level 3: Localized Response - Responses are somewhat purposeful and focused.
- RLA Level 4: Confused Agitated - A state of disorganized movement and confused behaviors.
- RLA Level 5: Confused Inappropriate - Exhibits inconsistent responses and difficulty in communication.
- RLA Level 6: Confused Appropriate - Responses are more coherent but still confused.
Brain Function Areas
- Temporal lobe: Responsible for auditory stimuli reception and short-term memory.
- Parietal lobe: Processes and interprets different sensory inputs.
- Occipital lobe: Manages the reception and interpretation of visual stimuli.
- Cerebellum: Regulates motor coordination and balance unconsciously.
- Brainstem: Controls autonomic responses, such as breathing and digestion.
Traumatic Brain Injury (TBI) Statistics
- Striking or being struck by an object is the third leading cause of TBI, with sports like diving, contact football, and rugby being significant contributors.
- Violence-related injuries from assaults or battery also contribute to TBI cases.
- Alcohol is the largest indirect cause of TBI, especially in vehicle crashes.
Risk Factors
- Attention deficit and hyperactivity disorder (ADHD) increases the risk of falls.
- Socioeconomic factors, such as low economic status and rural living, correlate with higher TBI incidence due to lack of education and safety gear.
- Firearm-related violence, both legal and illegal, contributes to TBI risk.
Cognitive Functions and Impairments
- Cognitive control largely resides in the frontal lobe, impacting functions such as arousal, attention, concentration, and memory.
- Cognitive impairments commonly observed in TBI patients include lethargy, confusion, and impaired attentiveness.
Coma Recovery Sequence
- Eye opening is the first indicator of recovery, followed by brainstem function restoration and the ability to follow commands.
- Neurobehavioral impairments often provide insight into cognitive deficits affecting daily function.
Manifestations of TBI
- Key symptoms include low frustration tolerance, agitation, impulsivity, and emotional lability.
- Difficulty in communication can result in disorganized speech and inappropriate social interactions.
- Mental inflexibility may hinder switching between thoughts and processing new information.
Communication Challenges
- Patients may exhibit deficits in organizing speech and word retrieval.
- Poor recall of new information and confusion in day-to-day interactions are common.
- Therapeutic approaches emphasize structure and repetitive instruction for better comprehension and engagement.
Cerebral Contusions
- Also called Parenchymal Contusion or Cortical Bruising, results from low-velocity impacts like blunt trauma.
- Patients may display confusion and nonsensical statements due to brain contact with external objects.
Post-Traumatic Confusional State
- Characterized by poor attention and disorientation.
- Use of step-by-step commands and clear communication can aid patient recovery.
- Avoid assumptions about patient memory and provide maximum structure during activities.
