Teaching Video NeuroImages: Palatal tremor in adult-onset Alexander disease.
A 67-year-old man presented with a several-year history of progressive gait ataxia, dysarthria, and a 2-Hz palatal tremor (video on theNeurology®Web site at Neurology. org). He did not have corticospinal tract signs. Cranial MRI revealed hypertrophic olivary degeneration on T2-weighted images (figure). Genetic testing revealed a transition C . T, nucleotide position 235, codon 79, resulting in ...
متن کاملTeaching Video NeuroImages: Re-emergent jaw tremor in Parkinson disease.
A 77-year-old woman who was diagnosed with Parkinson disease at 51 years of age presented with a 4-year history of intermittent jaw tremor. This was present at rest and declined in amplitude during voluntary movements. Tremor reappeared after the patient bit a tongue depressor continuously for 10 seconds (video on the Neurology® Web site at Neurology.org). “Re-emergent tremor” is a postural han...
متن کاملTeaching neuroImages: Rest tremor mimicking ventricular tachycardia.
Ventricular tachycardia is a life-threatening condition. ECG artifact caused by the 4to 6-Hz rest tremor of Parkinson disease (PD) can mimic a wide complex ventricular tachycardia (figure). Misinterpretation of ECG artifact can have grave consequences, including cardiac catheterization, administration of antiarrhythmics, and placement of automated implantable cardioverter-defibrillators.1 Tremo...
متن کاملPrimary writing tremor.
We describe a patient who complained of jerking of the right forearm on writing. Active pronation of his arm produced several beats of pronation/supination tremor. A burst of tremor also could be elicited by tendon taps to the volar surface of the wrist, to the finger extensors, and to pectoralis major, and by forcible supination of the wrist delivered by a torque motor. The subject's writing d...
متن کاملTeaching video neuroimages: complicated scapular winging.
Scapular winging (SW) is a common sign in neuromuscular disorders. Besides “pure” phenotypes due to single muscle weakness often secondary to nerve injuries or dysfunctions, the phenotype can be complicated when a combination of different scapular fixators is involved by a myopathy. We show an example of 2 sisters with facioscapulohumeral muscular dystrophy (video 1 on the Neurology® Web site a...
