    […] reduction in speed and amplitude of repetitive actions) and at least one of the following: (i) muscular rigidity, (ii) 4–6 Hz rest tremor and (iii) postural instability not[doi.org] (hand, leg or jaw; low frequency [4–5 Hz], asymmetric, disappears with action) - Excellent response to levodopa (70%–100%) - Progressive disorder - Severe levodopa-induced[dx.doi.org] Step 1: Diagnosis of a parkinsonian syndrome Bradykinesia (slowness of initiation of voluntary movement with progressive reduction in speed and amplitude of repetitive actions[doi.org]

  • Spinocerebellar Ataxia Type 12

    SCA12 is a late-onset, autosomal dominant, slowly progressive disorder. Action tremor is the usual presenting sign.[jhu.pure.elsevier.com] . • BULGING EYES: Lid retraction & infrequent blinking • In advanced stages: dysphagia,facial palsy,tongue atrophy. • Younger onset demonstrate rigidity and dystonia 93.[slideshare.net] SCA12 is a late-onset, autosomal dominant , slowly progressive disorder. Action tremor is the usual presenting sign.[ncbi.nlm.nih.gov]

  • Bradykinesia

    The usual course is for gradual progression. 26-9. How do you recognize essential tremor? Answer 26-9.[dartmouth.edu] Parkinson's facies: A stoic, mask-like facial expression, with infrequent blinking; it is characteristic of Parkinson's disease.[webmd.com] The tremor appears with sustained postures and is often obvious with movements (an action tremor).[dartmouth.edu]

  • Extrapyramidal Disorder

    The usual course is for gradual progression. 26-9. How do you recognize essential tremor? Answer 26-9.[dartmouth.edu] Disturbance in the maintenance of emotional and associated movements resulting in bradykinesia (mask face, infrequent blinking and loss of swinging during walking) 9.[slideshare.net] The tremor appears with sustained postures and is often obvious with movements (an action tremor).[dartmouth.edu]

  • Atypical Juvenile Parkinsonism

    This is another progressive condition with no cure or treatment as yet.[mycareladies.co.uk] blinking, lack of facial expression, impaired postural reflexes, and gait abnormalities.[merckmanuals.com] People with MSA-C may show an “action tremor,” or tremor that happens when they reach for an object. Muscle weakness can cause slurring and trouble swallowing.[myparkinsonsteam.com]
