2.3.2 Neurological Diagnosis

Question 1

What are the 3 steps in the neurologic diagnostic process?

Answer 1

Syndrome - signs and symptoms

Lesion - location

Etiology - what caused the lesion

Question 2

Fill in this chart describing the characteristics of lesions found in the UMN or LMN

Answer 2

Question 3

What are the four major lesion categories?

Answer 3

Lateral (Focal), Diffuse, Midline, and Mult-focal

Question 5

What two factors of shared anatomy can lead to focal lesions in the PNS?

Answer 5

Proximity and blood supply

Question 6

What two factors/etiologies of shared physiology can lead to diffuse lesions in the PNS?

Answer 6

Toxin sensitivity and Metabolic insult sensitivity

Question 7

What are the three steps in the lesion localization process?

Answer 7

1. Determine the subsystem involved
2. Determine the likely localization based on the pattern and nature of deficits
3. Confirm and refine localized with other subsystems

Question 8

What are some sources of diffuse muscle weakness?

Answer 8

Muscle, NMJ, diffuse neuropathy, LMN neuropathy, UMN neuropathy
