392 Possible Causes for Variable Tremor

  • Peripheral Neuropathy

    This leads to the development of a variable tremor.[news-medical.net]

  • Essential Tremor

    A variability of tremor frequency between postural and kinetic tasks has been proposed in ET, suggesting either multiple central oscillating networks, or peripheral or proprioceptive[ncbi.nlm.nih.gov] […] ratings in detecting changes in essential tremor that exceed random variability in tremor amplitude.[ncbi.nlm.nih.gov] We observed a marked increase in tremor and its variability, as well as the "freezing" of the movement pattern as effects of the cognitive load.[ncbi.nlm.nih.gov]

  • Acute Amphetamine Intoxication

    Results: The clinical presentation was variable deterioration in level of consciousness, somnolence, ataxia, tremor, apnea, hypotonia and seizure.[omicsonline.org]

  • Orthostatic Hypotension

    Patients with the MSA parkinsonian variant have variable parkinsonian findings, including rigidity, bradykinesia, tremor, and truncal instability, that do not respond to levodopa[emedicine.medscape.com] […] parkinsonian findings: Found in MSA parkinsonian variant; are unresponsive to levodopa; include rigidity, bradykinesia, tremor, and truncal instability Evidence of cerebellar[emedicine.medscape.com] […] present: Pyramidal or cerebellar abnormalities: Weakness, ataxia, incoordination, and eye-movement abnormalities may precede the autonomic features by as long as 2 years Variable[emedicine.medscape.com]

  • Chronic Obstructive Pulmonary Disease

    Although tremors, tachycardia, and palpitations are considered the more common adverse events associated with β 2 -agonists, they occurred at very low rates when reported,[ncbi.nlm.nih.gov] […] adverse events, when reported, may also be considered disease related and typically included respiratory tract infections, nasopharyngitis, and cough, although there was some variability[ncbi.nlm.nih.gov]

  • X-linked Parkinsonism-Spasticity Syndrome

    Format Definition A syndrome characterized by parkinsonian features, such as cogwheel rigidity, resting tremor and bradykinesia, and variably penetrant spasticity.[uniprot.org] , and variably penetrant spasticity.[malacards.org] Upper limb tremor is most commonly psychogenic. Variable tremor frequency is consistent with a psychogenic cause.[stanfordmedicine25.stanford.edu]

  • Posterior Cerebral Artery Occlusion with Infarction

    Variable effects from thalamic syndrome to varieties of cortical visual disturbance.[patient.info] Severe ipsilateral cerebellar ataxia • Nausea & vomitings • Dysarthria • Contralateral loss of pain & temperature over extremities, body & face. • Partial deafness, ataxic tremor[slideshare.net] Contralateral tremor, ataxia or chorea. Posterior cerebral artery occlusion: Most often causes occipital lobe infarction with hemianopia and macular sparing.[patient.info]

  • Psychogenic Movement Disorders

    Polymyography coupled to accelerometry is used to demonstrate the major electrophysiological criteria of psychogenic tremor, namely spontaneous variability of tremor frequency[ncbi.nlm.nih.gov] The diagnosis should rest on positive findings such as paroxysmal nature, maximum severity at or near onset, variability of tremor direction, frequency and amplitude, entrainment[ncbi.nlm.nih.gov] Psychogenic tremor will have variable frequency over time, be synchronous in the two arms, and might well be entrained with voluntary rhythmic movements.[ncbi.nlm.nih.gov]

  • Posterior inferior cerebellar artery occlusion

    Variable effects from thalamic syndrome to varieties of cortical visual disturbance.[patient.info] Contralateral tremor, ataxia or chorea. Posterior cerebral artery occlusion: Most often causes occipital lobe infarction with hemianopia and macular sparing.[patient.info]

  • Orthostatic Syncope

    […] parkinsonian findings: Found in MSA parkinsonian variant; are unresponsive to levodopa; include rigidity, bradykinesia, tremor, and truncal instability Evidence of cerebellar[emedicine.medscape.com] […] present: Pyramidal or cerebellar abnormalities: Weakness, ataxia, incoordination, and eye-movement abnormalities may precede the autonomic features by as long as 2 years Variable[emedicine.medscape.com]
