Visible Tongue Fasciculations With Electromyographic Denervation in Autopsy‐Proven Progressive Supranuclear Palsy Mimicking Amyotrophic Lateral Sclerosis

Puntos clave

• This study aims to explore the presence of tongue fasciculations and denervation in progressive supranuclear palsy and how it mimics amyotrophic lateral sclerosis.
• Case report detailing clinical findings of an autopsy-proven progressive supranuclear palsy case.
• Electromyographic analyses were performed to assess denervation and fasciculations in the tongue.
• Visible tongue fasciculations were documented, indicating muscle nerve involvement.
• Electromyographic evidence confirmed denervation, showing overlap with ALS clinical features.
