Abstract

The history of pharmacological research and drug prescription for dementia is briefly overviewed. The Authors stress the intrinsic ambiguity of the area of dementia and the lack of any strong correlation between clinical manifestations and etiopathogenetic mechanisms. Moreover, they criticize the methodological flaws of most clinical trials, especially concerning sample size and duration of follow-up. They put forward some recommendations for future trials, favouring a more pragmatic approach, a larger number of subjects involved and a longer duration of follow-up. Finally they make out a case for establishing a multicenter observatory of the Commissions for human experimentation.

Sommario

Viene brevemente passata in rassegna la storia della ricerca farmacologica e della prescrizione di farmaci per la demenza. Gli autori sottolineano l'intrinseca ambiguità dell'area della demenza e la mancanza di strette correlazioni fra manifestazioni cliniche e meccanismi eziopatogenetici. Essi criticano i difetti metodologici della maggior parte degli studi clinici, specialmente riguardo alla dimensione del campione e alla durata del follow-up. Essi avanzano alcune raccomandazioni per i futuri studi clinici, suggerendo un approccio pragmatico, un maggior numero di soggetti per ogni studio e una maggior durata del follow-up. Infine essi auspicano che venga istituito un osservatorio multicentrico delle Commissioni per la sperimentazione umana.
