Which condition should be suspected when a patient presents with bilateral facial weakness, unblinking expression, and a “horizontal” smile (inability to elevate the angles of the mouth)?

Bilateral facial weakness can be challenging to detect due to the symmetrical features. However, in cases where patients fail to elevate the angles of their mouth during a smile, have impaired speech (especially labial sounds like ‘puh’), and cannot form a seal with their lips when asked to blow out their cheeks, consider progressive supranuclear palsy (PSP). In severe cases, the eyes may roll up as the patient blinks (Bell’s phenomenon).
