The Mini Mental State Exam (MMSE) is a general assessment of cognitive impairment. The Pyramids and Palm Trees test assesses semantic memory. The Rey Complex Figure test examines visuospatial abilities and episodic recall. “Years from symptom onset” measures the number of years between the test date and the year that the patients or their caregivers reported first observing symptoms. “Months from first clinic visit” measures the number of months between the test date and the date of the patient’s first visit to the neurology clinic at the University of Pennsylvania.
