 To the researchers knowledge, very few randomized controlled clinical trials have tested the effectiveness of non-pharmacological interventions in patients with a mean age of 60 years and older. Data from these studies showed that brief intervention e.g. receiving either an informative leaflet on BZD withdrawal during a meeting with the doctor or an informative letter by post mail or psychological interventions including cognitive behavioral therapy or CBT are most likely more effective than the standard care and in some cases, to the gradual dose reduction GDR supervised by a physician. However, only 10 brief intervention to 85 cognitive behavioral therapy designed to treat insomnia of participants completely stopped BZD use at the end of treatment. Furthermore, Parr and colleagues indicate that the complete stop of BZD consumption remains difficult and still a big challenge to patients, clinicians and researchers.
