The diagnostic value of midbrain hyperechogenicity in ALS is limited for discriminating key ALS differential diagnoses

BACKGROUND Hyperechogenicity of the substantia nigra was recently reported in patients with sporadic ALS with a frequency similar to PD. Data on the diagnostic utility compared to key differential diagnoses of ALS do not exist yet. METHODS We prospectively enrolled 43 patients with ALS, 29 with myasthenia gravis, 25 patients with inflammatory neuropathy, and 13 with cervical canal stenosis. A...

The First ALS Ambulance in the World

The survival rate of medical emergencies depends highly on the intervention time and prompt medical care on the scene. The idea of “bring the doctor and medical equipment to the spot” was born in Hungary in the mid-1950s. The demand for advanced life support was a consequence of the fast growth of industry and traffic. It is worthwhile to review the development of the idea, the therapeutic meth...

Is all ALS genetic?

What is “Hyper” in the ALS Hypermetabolism?

The progressive and fatal loss of upper (brain) and lower (spinal cord) motor neurons and muscle denervation concisely condenses the clinical picture of amyotrophic lateral sclerosis (ALS). Despite the multiple mechanisms believed to underlie the selective loss of motor neurons, ALS aetiology remains elusive and obscure. Likewise, there is also a cluster of alterations in ALS patients in which ...
