176 Possible Causes for Cogwheel Rigidity

  • Postencephalitic Parkinson Disease

    Cogwheel rigidity will be appreciated with passive movement of the patients limb.[thebigl.co] Parkinson's disease is recognized by the presence of at least three of four cardinal signs: resting tremor, cogwheel rigidity, bradykinesia/akinesia, and postural reflex impairment[parkinsonsmi.org] The abnormal tone is referred to as lead-pipe and cogwheel rigidity.[enotes.tripod.com]

  • Neuroleptic Malignant Syndrome

    Motor abnormalities: Patients may have generalized, severe muscle rigidity (sometimes with simultaneous tremor, leading to cogwheel rigidity), or, less often, dystonias, chorea[msdmanuals.com] We present video evidence of the effectiveness of dantrolene in reducing muscular rigidity, tremor and cogwheel phenomena in a patient with NMS.[ccforum.com] Muscle rigidity, cogwheel phenomena and tremor disappeared within 10 min (video footage is available in Additional file 2 ), but they gradually reappeared within an hour.[ccforum.com]

  • Methylphenyltetrahydropyridine

  • Parkinsonian Disorder

    (cogwheel and lead-pipe rigidity), festinant gait, stooped posture, mask-like facies and eventual progressive dementia par·kin·son·ism ( pahr'kin-sŏn-izm ) Neurologic syndrome[medical-dictionary.thefreedictionary.com] […] characterized by insidious onset of rhythmical muscular tremors at rest (pill-rolling tremor; 4–6 Hz), paucity and slowness of movement (hypokinesia, bradykinesia) and generalized rigidity[medical-dictionary.thefreedictionary.com]

  • West Nile Encephalitis

    At hospital admission, a masked facies and bilateral upper and lower extremity cogwheel rigidity were present.[jamanetwork.com]

  • Parkinson's Disease

    In parkinsonism the rigidity can be uniform ("lead-pipe rigidity") or ratchety ("cogwheel rigidity").[en.wikipedia.org] rigidity (catching and releasing) or lead-pipe rigidity (continuously rigid); rigidity must be distinguished from spasticity, which has only increased flexor tone; rigidity[aafp.org] Rigidity Rigidity is characterised by increased resistance, usually accompanied by the “cogwheel” phenomenon, particularly when associated with an underlying tremor, present[web.archive.org]

  • Juvenile Paralysis Agitans of Hunt

    Major features Resting tremor in hands, arms, legs, jaw, and face Bradykinesia Rigidity- cogwheel or lead-pipe Minor features Bradyphrenia Speech abnormalities Depression[slideplayer.com]

  • Parkinson-Dementia Syndrome

    BACKGROUND: Dementia represents one of the most challenging health problems. Despite intense research, available therapies have thus far only achieved modest results. Deep brain stimulation (DBS) is an effective treatment option for some movement disorders and is under study for psychiatric applications. Recently,[…][ncbi.nlm.nih.gov]

  • Parkinson's Disease Type 3

    Parkinson's disease type 3 (PD3) is a form of Parkinson's disease that is inherited in an autosomal dominant manner. The underlying mutation has not yet been identified, but PD3 has been related to a 2.5 Mb-locus on the short arm of chromosome 2. To date, PD3 has been diagnosed in distinct families in Europe and[…][symptoma.com]

  • Dementia with Lewy Bodies

    Dementia with Lewy bodies (DLB) is increasingly recognized as a common cause of dementia in older people. However, its true frequency remains unclear, with previous studies reporting a prevalence range from zero to 22.8% of all dementia cases. This review aimed to establish the population prevalence and incidence[…][ncbi.nlm.nih.gov]
