Episode notes
Generalized Weakness Overview
- Generalized weakness can stem from neurologic or systemic issues like anemia or infections.
- True neurologic weakness involves decreased muscle power, localizing from brain to muscle.
Key History Questions
- Focus on symptom onset, pattern, and associated issues like sensory disturbances or bowel/bladder problems.
- Consider the patient's context, age, and medical history for accurate diagnosis.
Around-the-Clock Pattern
- Weakness progressing from one leg to the other, then to the arms, follows the "around-the-clock" pattern.
- This unusual pattern suggests a lesion at the cervical medullary junction, although rare.
