Concentrations of cortisol, dehydroepiandrosterone and dehydroepiandrosterone-sulfate were measured by performing radioimmunoassay of the cerebrospinal fluid of 68 dogs diagnosed with idiopathic epilepsy or inflammatory, degenerative, or non-neurological disease. No steroid concentration differences were found among diagnoses. Dehydroepiandrosterone and dehydroepiandrosterone-sulfate concentrations were higher in males than in females and dehydroepiandrosterone-sulfate decreased with increasing age. No sex or age effects were observed on cortisol or hormone ratios. Although limited to a relatively small sample, our results show sex- and age-dependent variations in these neurosteroid concentrations in cerebrospinal fluid. The role of such variations in the pathophysiology of the dog brain warrants further investigation.
