2. Gradually progressive proximal and distal disease without fatigability.
3. Asymmetric bilateral without eye involvement.
4. Recognizing lower motor neuron signs including fasciculations, weakness, atrophy, and the EMG test.
5. Recognizing upper motor neuron signs including weakness and retained reflexes in the face of 3/5 weakness. If all of the disease was LMN, the reflexes would be absent.
