Stimulus-induced or spontaneous myoclonus is most specific for which disease?

Explanation:
Stimulus-induced or spontaneous myoclonus points to Creutzfeldt-Jakob disease because this rapid, prion-mediated dementia characteristically features sudden, involuntary jerks that can be triggered by sensory stimuli or occur spontaneously. This pattern is much more specific to CJD than to other neurodegenerative diseases. Alzheimer disease centers on memory loss and gradual decline; Huntington disease presents with chorea and behavioral changes; Parkinson disease shows resting tremor, rigidity, and bradykinesia. So the presence of myoclonus in this context is a hallmark that most strongly supports CJD.
