98 Possible Causes for Artefact - Patient Movement, Infrequent Blinking

  • Parkinson's Disease

    A total of five scans showed severe artefact due to patient movement preventing the assessment of the presence of nigrosome-1.[doi.org] No cases were excluded from the analysis due to poor quality or movement artefact. 16 subjects (8 PD and 8 controls) were correctly classified by both raters independently[doi.org] We also excluded patients with structural brainstem pathology resulting in distortion of the substantia nigra (n   4).[doi.org]

  • Graves Disease

    Note her thyrotoxic stare (infrequent blinking with exophthalmos) and enlarged thyroid gland (goiter).[emedicine.medscape.com] Signs and symptoms of thyrotoxic Graves disease include an enlarged thyroid, rapid heart rate, widened pulse pressure, a hyperthyroid stare (infrequent blinking) or frank[emedicine.medscape.com]

  • 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]
