title: Reversal of brain dysfunction with UV-A1 irradiation in a patient with systemic lupus.
abstract: Low-dose ultraviolet A-1 (UV-A1; 340-400 nm) bodily irradiation significantly reduces clinical manifestations of systemic lupus erythematosus (SLE). As neuropsychiatric-like symptoms respond prominently, a single patient was selected to undergo positron emission tomography (PET) before and after therapy to determine the effects of the therapy on the brain. The functional changes in 18F-deoxyglucose uptake as determined by PET imaging in this SLE patient indicated that improvement in brain function paralleled the reversal of cognitive deficits noted after the administration 160 kJ of bodily UV-A1 irradiation administered three times a week. Also of interest is that the UV-A1 irradiation, for the first time, ameliorated discoid lupus rashes, presumably due to a systemic action, as the lesions were for the first time covered during therapy.
