Long-term idebenone treatment of vascular and degenerative brain disorders of the elderly.
A multicentre study with an open experimental design was carried out on 118 patients suffering from mild to moderate cognitive decline due to cerebrovascular and degenerative disorders (chronic cerebrovascular disorders, CCVD; multi-infarct dementia, MID; aging brain, AB; dementia of Alzheimer's type, DAT). All patients, after a wash-out period of 3 weeks, were treated with idebenone (45 mg twice daily by oral route) for a period of 6 months. Behavioral and cognitive measures (Sandoz Clinical Assessment of Geriatrics, SCAG; Serial Learning Test) were applied to evaluate the long term therapeutical aspects. The results, analyzed by multivariate analysis of variance and chi2 test, showed a significant improvement of the cognitive profile in all patients, more evident in CCVD and AB groups. No remarkable side-effects were found in all groups of patients, thus confirming good tolerability of idebenone.
