Background: Lyme borreliosis (Lyme disease), a tick-borne spirochetal
illness. has later manifestations that may include arthritic. neurolog
ic, ophthalmologic, and cardiac symptoms. Recent reports suggest psych
iatric symptoms may also be part of the clinical picture. Method. Usin
g a structured interview (SCID), we interviewed three patients who had
developed a psychiatric disorder for the first time after infection w
ith Borrelia burgdorferi. Results: During Lyme borreliosis, one patien
t had major depression and panic disorder, one patient had an organic
mood syndrome with both depression and mania, and the third patient ha
d panic disorder. These disorders remitted after adequate antibiotic t
reatment. Conclusion: While depression has been previously linked to n
euroborreliosis, this is the first report to link panic disorder and m
ania with borrelial infection. Because of the rapid rise of Lyme borre
liosis nationwide and the need for antibiotic treatment to prevent sev
ere neurologic damage, mental health professionals need to be aware of
its possible psychiatric presentations.
