Case Summary:
We present two probable CJD cases seen in the same hospital within one month. Case one was a 67-year-old white female, former psychology practice manager, presenting with worsening cognition, vertigo, behavioral changes and 15 lb weight loss over 6 months. Exam findings significant for MoCA of 17/30 (decreased to 15/30 after one week), constant right eye shut, mild dysmetria in both lower extremities, a wide based gait with small strides. Blood work and initial Spinal fluid studies were negative. Continuous EEG showing occasional right temporal slow, frequent generalized rhythmic theta and delta slowing. MRI brain findings were suggestive of CJD with hyperintensities in bilateral caudate nucleus and putamen. Patient did not respond to high dose steroid.
Case two was a 78-year-old white male, admitted for deterioration in cognition, gait, speech, fatigue and intermittent body jerking. Progression of his symptoms was so rapid, from a highly functional retired funeral director, he became minimal speech, loss of ADL within 3 months. Exam was significant for orientation to self only, global aphasia, muscle weakness and startle myoclonus. Blood work and initial spinal fluid studies were negative. MRI brain showed asymmetric cortically based diffuse restriction within cingulate, caudate nucleus also left temporoparietal. EEG showed generalized rhythmic delta activity.
CSF from both cases eventually showed positive RT-QuIC, 14-3-3 protein and highly elevated T-Tau protein.
