Can a tremor of the tongue be an essential tremor?
It commonly affects the arms, and to a lesser extent, other regions of the body, and signs and symptoms tend to worsen during emotional or physiological stress. We describe a rare isolated presentation of tongue tremor as a part of essential tremor, its management, and the diagnostic dilemma.
Can a resting tongue be a sign of Parkinson’s disease?
Resting tremor is part of the classical parkinsonian triad and classically observed in the upper or lower limbs, legs, mandible, chin, and lips, but tongue tremor is far less often reported, especially as a revealing manifestation of Parkinson’s disease (PD).[1] Here, we describe a 63-year-old patient with a resting tongue tremor as the first
Can a neuroleptic medication cause a tongue tremor?

Is there such a thing as essential tremor?
Tongue tremor is commonly associated with essential tremor, but rarely presents as an initial finding. Essential tremor is the most common movement disorder and is characterised by 4–12 Hz postural and kinetic tremor, but there is no universally accepted diagnostic criterion.
