    Study Notes

    Neurological Assessment

    • Brain Anatomy:

      • Cerebrum: Responsible for higher-level functions (emotions, cognition, personality) divided into four lobes:
        • Frontal: Emotions, cognition, personality, Broca's area
        • Parietal: Sensory information integration
        • Temporal: Smell, sound, language
        • Occipital: Vision
      • Cerebellum: Balance and coordination
      • Brainstem: Vital functions

    • Neurological Functions:

      • Sensory: Sight, hearing, smell, touch, etc.
      • Motor: Movement, strength, range of motion (ROM), gait
      • Cognitive: Mental status, orientation, memory

    • Neurological Assessment Timing: Neurological assessment begins immediately upon entering the room. Mental status is prioritized, especially in older adults, as an early indicator of potential problems.

    Stroke Assessment

    • Stroke Symptoms:

      • Sudden, unilateral muscle weakness
      • Slurred speech
      • Facial droop
      • Aphasia (difficulty speaking or understanding speech)
      • Unequal strength/movement on one side of the body/face

    • Stroke Onset: Symptoms onset can be sudden, and any asymmetry in strength or movement between sides of the body or face should be immediately evaluated.

    • Priority of Stroke Assessment: Immediate assessment is crucial to minimize potential permanent deficits.

    • Unilateral vs. Bilateral Symptoms: Unilateral symptoms (one side) are more concerning for stroke.

    • Assessment for Stroke Suspicion: Complete neurologic assessment is required if stroke is suspected.

    • Side of Body Deficit: Stroke deficits typically manifest on the opposite side of the body compared to the damaged brain region (contralateral).

    Posturing

    • Decorticate Posturing: Inward arm positioning
    • Decerebrate Posturing: Outward arm positioning

    Romberg Test

    • Procedure: Patient stands with feet together, eyes closed.
    • Nurse Positioning: Nurse stands beside the patient, positioned to prevent falls.
    • Instructions: Patient closes eyes.
    • Assessment: Assessing balance, coordination, and proprioception (position sense).
    • Positive Test: Swaying or falling, using arms to maintain balance.
    • Negative Test: Maintains posture without assistance.
    • Normal Result: Negative test.
    • Positive Result Indication: Cerebellar dysfunction.

    Mental Status Assessment

    • Glasgow Coma Scale (GCS): Scale used to assess the level of consciousness and cognitive function in patients with a possible brain injury.
    • Interpretation & Scoring: GCS scores help determine the severity of a possible brain injury (mild, moderate, and severe).

    Cranial Nerves

    • Eye Movement & Pupil Reactivity (3, 4, 6):

      • Oculomotor (CN III): Eye movement, pupil reactivity
      • Trochlear (CN IV): Eye movement
      • Abducens (CN VI): Eye movement, pupil reactivity

    • Gag Reflex (9):

      • Glossopharyngeal (CN IX): Gag reflex. Taste. Posterior tongue, tonsils, pharynx, and pharynx muscles
      • Necessary Equipment: Tongue depressor
      • Next Assessment If Gag Absent: Check pharyngeal sensation
      • Additional Functions: Taste - does not include speech/chewing. Distiguishing CN IX and X is critical.

    • Tongue Position & Movement (12):

      • Hypoglossal (CN XII): Midline positioning and side-to-side movement of the tongue.

    • Chewing (5):

      • Trigeminal (CN V): Chewing (clenching teeth)

    • Facial Movement (7):

      • Facial (CN VII): Facial expressions (smiling, frowning, puffing cheeks)

    • Vision (2):

      • Optic (CN II): Vision
