The diagnosis of ALS often comes after the exclusion of all other conditions
to explain symptoms. While there is no single definitive test for ALS, specialists
will often diagnose it after evidence of both upper and lower neuron signs in a
single limb. Specialists will also go through a patient’s medical history to look
for the presence of other symptoms that may be associated with ALS.
Specialists will likely conduct multiple tests that can be used to rule out other
diseases to help establish an ALS diagnosis.
-
Electromyography (EMG) is a recording technique that may be used to detect electrical
activity in the muscle
- Magnetic
Resonance Imaging (MRI) is a high-contrast, two-dimensional view of the brain
and spinal cord. This test can help your doctor determine if something other than
ALS may be causing your signs and symptoms
- Blood and urine samples may be taken to rule out other diseases or conditions
- Biopsy may be done to check the health of the muscle.
This involves taking cells from the muscle
while a patient is under anesthesia
