Abstract:

Repetitive transcranial magnetic stimulation (rTMS) is increasingly used clinically in the treatment of patients with major depressive disorder (MDD). However, rTMS treatment response can be slow. Early research suggests that accelerated forms of rTMS may be effective but no research has directly evaluated a schedule of accelerated rTMS compared to standard rTMS. To assess the efficacy of accelerated rTMS compared to standard daily rTMS., 115 outpatients with MDD received either accelerated rTMS (n = 58) (i.e., 63,000 high frequency rTMS pulses delivered as 3 treatments per day over 3 days in week 1, 3 treatments over 2 days in week 2 and 3 treatments on a single day in week 3) or standard rTMS (n = 57) (i.e., 63,000 total high frequency rTMS pulses delivered over 5 days per week for 4 weeks) following randomization. There were no significant differences in remission or response rates (p > 0.05 for all analyses) or reduction in depression scores (Time by group interaction (F (5, 489.452) = 1.711, p = 0.130) between the accelerated and standard rTMS treatment groups. Accelerated treatment was associated with a higher rate of reported treatment discomfort. It is feasible to provide accelerated rTMS treatment for outpatients with depression and this is likely to produce meaningful antidepressant effects.

Nota:

Questo studio mette a confronto la stimolazione magnetica transcranica tradizionale con la stimolazione magnetica transcranica ad alta frequenza. 115 pazienti affetti da depressione hanno effettuato 3 settimane di trattamento con rTMS ad alta frequenza e rTMS standard. Non si sono dimostrate differenze significative tra i due tipi di stimolazione. La stimolazione ad alta frequenza ha provocato un fastidio legato al trattamento in molti soggetti del gruppo che l'hanno sperimentata.
