With the help of Dr. Jean-François Virolés, I’ve established a list of differential diagnosis that exists for ALS:
– Heavy metal poisoning
– Neurological form of Lyme disease (neuroborreliosis)
– Guillain-Barré syndrome
– Motor neuropathy
– Muscle weakness (myasthenia)
– Post-polio syndrome
– Cramp fasciculations syndrome
– Paraneoplastic syndrome
– Sjögren’s syndrome
– Some endocrine disorders
– Retroviral infections
– Some metabolic disorders
– Genetic conditions (Kennedy’s syndrome and spinal muscular atrophy)
– Inclusion body myositis
– Some spinal-cord compression disorders
With the stacks of rare diseases in this world, I’m sure there’s gotta be more to include here, but these are the most common ones.
Have a nice day.
