The most effective predictor of survival is the rate of observed disease progression, estimated via the time between symptom onset and diagnosis or evaluated by employing measures such as the ALS Functional Rating Scale (ALSFRS).
What are the markers for ALS?
In human ALS muscle, mitochondrial defects including dysregulation of respiratory complex I (44), decreased respiratory complex I and IV activity (45, 75), decreased muscle mitochondrial protein expression (75) and upregulation of muscular mitochondrial uncoupling protein 3 (76) indicate that impairments in …
How do you monitor ALS?
Tests to rule out other conditions might include:
- Electromyogram (EMG). Your doctor inserts a needle electrode through your skin into various muscles.
- Nerve conduction study.
