T. Silverstone et al., HOW EFFECTIVE IS LITHIUM IN THE PREVENTION OF RELAPSE IN BIPOLAR DISORDER - A PROSPECTIVE NATURALISTIC FOLLOW-UP-STUDY, Australian and New Zealand Journal of Psychiatry, 32(1), 1998, pp. 61-66
Objective: The effectiveness of lithium in preventing recurrences of b
ipolar disorder was examined prospectively for 2 years in two represen
tative samples of bipolar I patients being treated in a comprehensive
program following recommended guidelines. Method: One hundred and twen
ty patients were recruited from consecutive admissions to two catchmen
t area psychiatric services (one in the United Kingdom, the other in N
ew Zealand). They were seen at 3-monthly intervals by a member of the
research team. Treatment was adjusted according to clinical needs. Res
ults: Overall, two-thirds of the patients had a recurrence. Of the 57
on lithium as sole treatment, 39 (68%) had a further episode; 17 after
stopping lithium. The 42 on other mood stabilisers and/or an antipsyc
hotic, with or without lithium, did no better. By contrast, only eight
(38%) of the 21 who were taking no prophylactic medication had a recu
rrence. Conclusions: Lithium is much less effective in clinical practi
ce than would be expected from clinical trial results. A major reason
for this is poor compliance. Alternative treatment strategies are need
ed to improve the outcome for bipolar disorder patients.
