Neurology: Case of the Month

History and Physical — Patient 85

History

Present Illness: A 53 year old, left-handed Hispanic gentleman was evaluated by the Neurology Service at the VA Medical Center for progressive memory problems and difficulty executing complex tasks. About five years ago, his family began to notice that he was having trouble counting merchandise correctly and could not handle money well. His problems have slowly but progressively worsened. He became no longer able to do the family finances, and while he was able to drive, he got lost easily. His family noted that he could no longer write words nor dial a telephone. While he worked for several years in auto repair business, he became unable do basic repairs, including simply putting a lock together. He was no longer able to read a newspaper because "the layout was confusing and he tried to read it like a book." He had moderate difficulty reading globally because his "eyes jump around from line to line." However, despite these cognitive complaints, he did not need verbal reminders. He remembered to take his medicines without the aid of a pill box. He had no difficulty feeding, dressing, or bathing himself. He denied feeling depressed. He and his family denied hallucinations, notable variability in his cognitive symptoms, abnormal movements, nor urinary incontinence. He was diagnosed with "multiple sclerosis" at an outside institution three years ago based on his brain MRI findings, but was not started on medication at that time. He has had no episodes of transient or permanent vision loss, weakness, or numbness.

Past Medical History: Hypothyroidism, hypercholesterolemia, and migraines. A concurrent diagnosis of "multiple sclerosis," per patient.

Medications: Aspirin 81 mg daily, levothyroxine 0.05 mg daily, simvastatin 80 mg daily.

Family History: Maternal uncle with Alzheimer's disease. Mother with colon cancer.

Social History: He was married, living with his family. He previously worked as a traveling salesman. He also earlier worked in the auto repair business. His family reported that he has been "always a little slow" cognitively. He stopped working secondary to cognitive problems.
