Study Notes
Altered Mental Status
- Defined as a disruption in wakefulness or arousal controlled by the reticular activating system in the brain.
- Consciousness can be altered due to various factors affecting the cerebral cortex.
Persistent Vegetative State
- A condition where the patient may be awake but lacks any cortical function.
Mnemonics for Causes of Altered Mental Status
- Metabolic disturbances (e.g., hypercalcemia, hyponatremia)
- Seizures
- Trauma
- Oxygen deprivation (hypoxia)
- Uremia
- Vascular issues (e.g., myocardial infarction, cerebrovascular accident)
- Psychiatric conditions
- Endocrine disorders (e.g., hypothyroidism, hypoglycemia)
- Infections
- Drugs and alcohol use
Patient Assessment Techniques
- Start with airway, breathing, circulation (ABC) checks.
- Assess cardiac rhythm, oxygen levels, and responsiveness to stimuli.
- Administer Narcan for opioid overdoses and Romazicon for benzodiazepine overdoses.
General vs. Focal Findings
- Generalized findings indicate systemic causes like intoxication or low glucose levels, presenting as symmetrical pupil responses and slurred speech.
- Focal findings may signify localized brain issues, leading to unilateral weakness, facial droop, or specific speech impairments.
Levels of Consciousness
- Lethargy: Patient responsive to stimulus; may require prompting.
- Obtundation: Requires constant stimulation to remain awake.
- Stupor: Cannot be awakened even with stimulus.
- Coma: Unresponsive to any stimuli, including painful ones.
Orientation and Language Assessment
- Check patients' knowledge of name, place, time, and current events.
- Misunderstandings can occur; some may appear aware but are confused.
- Language disorders include expressive, receptive, or global aphasia, causing challenges in comprehension or speech.
Glasgow Coma Scale
- Measures the best score across eye opening, verbal, and motor responses.
- Scores can range from 3 (deep coma) to 15 (fully awake and alert).
Eye Movement and Pupillary Assessment
- Eye gaze deviations can indicate lesions (toward lesion in hemiparesis).
- Pupillary assessment includes size, shape, reaction to light, symmetry, and accommodation.
Oculomotor Nerve (CN III)
- Controls eye movements and pupil constriction; vulnerable to compression.
- Dysfunction may lead to unequal pupil size or non-reactive pupils.
Pupil Characteristics
- Pinpoint pupils suggest opioid use.
- Dilated pupils can indicate brain damage or increased intracranial pressure.
Motor Assessment
- Evaluate range of motion, strength, coordination, and sensation in each limb.
- Use the NIH Stroke Scale to assess stroke severity; facial asymmetry and arm weakness are key indicators.
Sodium Abnormalities
- Hyponatremia can present as altered mental status, seizures, or coma.
- Hypernatremia also affects brain function; rapid correction risks central pontine myelinolysis.
Delirium vs. Dementia
- Delirium: Acute confusion with rapid onset, disorganized thinking, perceptual disturbances, and disorientation.
- Dementia: Progressive cognitive decline caused by brain damage or disease.
Causes of Delirium
- Neurotransmitter dysfunction, CNS processes, systemic diseases, toxins/medications, infections, hypoxia, urinary retention, and drug withdrawal.
Neurological Emergencies
- Conditions requiring immediate attention include intracranial aneurysm (CUA), intracerebral hemorrhage (ICH), status epilepticus, spinal cord compression, head trauma, and various encephalopathies (e.g., Wernicke's syndrome in alcoholics).
