| Research Abstract |
To our knowledge, there are only two prospective studies which have investigated the prognosis of rapid cycling affective disorder and their results vary quite considerably. Thus, the prognostic significance of rapid cycling remains an important question.
We followed up 30 rapid cyclers who were treated aggressively with lithium, carbamazepine and sometimes in combination with other drugs. Of these 30, fourteen stopped cycling rapidly within the first year. On the other hand, the remaining sixteen comtinued to cycle rapidly. Their treatment responses differ accordingly to the duration of rapid cycling prior to intensive treatment.
We also assessed hypothalamic-pituitary-adrenocortical axis function in patients with rapid cycling by measuring urinary free cortisol in the dexamethasone test. Our results show that rapid cycling patients have lower urinary free cortisol levels during hypomanic phases than during depressive phases. The present study confirmed the hypothesis that hypothalamic-pituitrary-adrenocortical axis function varies with the mood states of rapid cycling patients.
