This week’s Medical Challenge is from guest blogger Vincenzo Happach – medical student at DMU & good personal friend of mine. If you would like to submit a guest post or a medical case of your own, please use the contact page.
An 86 year old Caucasian female presents to the medicine floor after, while driving, she began to feel anxious, confused, and lost.

Upon examination the next morning the patient is oriented only to person. She knows she’s in the hospital but is not sure which one. Exam is notable only for bilateral peripheral neuropathy of the lower extremities. Gait is normal, strength is 5/5 & reflexes are 2+ in all extremities.
She has a past medical history of Anxiety, Hypothyroidism, and Diabetes Mellitus Type II. She admits to occasional incontinence of urine when startled or during bouts of laughter.
Her medications include Synthroid, Metformin, Aspirin, Lisinopril, Cymbalta and Glipizide.
