Psychological factors in the prediction of Lyme disease course.
OBJECTIVE
To determine whether history of severe, long-term, premorbid, psychological stress is associated with increased incidence of chronic physical symptoms in presumed Lyme disease patients.


METHODS
Fifty-seven patients presenting at Lyme Disease Clinic of Long Island Jewish-Hillside Medical Center were studied for presenting symptoms, presence or absence of Lyme disease, and past history of psychological trauma. They were restudied 1 to 1.5 years later for presence or absence of physical symptoms. Statistical analyses compared symptom course for patients with and without Lyme disease, antibiotic and nonantibiotic treatments, and past history of psychological trauma.


RESULTS
There was correlation between history of past traumatic psychological events and chronicity of physical symptoms whether or not the patient had presumed Lyme disease or had received antibiotic treatment.


CONCLUSIONS
Traumatic psychological experiences predating onset of Lyme disease symptoms may play an important etiologic role in the chronicity of these symptoms.
