Memantine in Vascular Dementia: Subgroup Analyses Analyses based on studies in patients with mild to moderate vascular dementia: • Orgogozo et al. (2002) (MMM300) • Wilcock et al. (2002) (MMM500) • ADAS-cog analysis by severity at baseline: • MMSE 20-22 • MMSE 15-19 • MMSE 10-14 • ADAS-cog analysis by neuroradiological findings at baseline: • Macrolesions, “Large Vessel Disease” • No macrolesions, “Small Vessel Disease” Möbius and Stöffler, Int Psychogeriatr 2003

Summary The strongest effect of memantine on cognition was shown • in the moderately demented patient population (MMSE < 15 at baseline) and • in the subgroup of patients with “small vessel disease” (no macrolesions in CT/MRI) Möbius and Stöffler, Int Psychogeriatr 2003
