  • 66 y/o man with intervals of AMS found to have Lewy body Dementia

    2016-07-28

  • Vascular causes of AMS are typically abrupt in onset
    Seizures can be non-convulsive and affect cognition
    Alzheimer's - Dementia advances before onset of motor symptoms

    MRI stroke protocol not as helpful as MRI Brain - given it does not have sagittal and T1 views. If not looking for acute stroke, can get full brain MRI for more information.

    MRI with contrast: Will see hyperintense lesions (new) and hypontense lesions (old). Old lesions on T1 imaging will appear as black holes.

  • Multiple Sclerosis:

    Prognostic Markers: 
    -- Primary Progressive – more rapid disease progression
    -- Men progressed more quickly but outcomes not affected
    -- Type of symptoms at onset did not predict disease progression
