Background: This study was designed to assess changes in brain volume and cognitive abilities in memantine-treated patients with Alzheimer’s disease (AD) by using an exploratory, single-arm, delayed-start design.; Methods: Cholinesterase inhibitor-treated patients with AD (N = 47; Mini-Mental State Examination score range: 15-23) were enrolled in an observational lead-in period (weeks: 1-24), followed by an […]

Background: Clinical trials have shown the benefits of cholinesterase inhibitors for the treatment of mild-to-moderate Alzheimer’s disease. It is not known whether treatment benefits continue after the progression to moderate-to-severe disease.; Methods: We assigned 295 community-dwelling patients who had been treated with donepezil for at least 3 months and who had moderate or severe Alzheimer’s […]
Sustained effects of once-daily memantine treatment on cognition and functional communication skills in patients with moderate to severe Alzheimer’s disease: results of a 16-week open-label trial

Sternberg, Kati,
Tennigkeit, Frank
The present study evaluated the effects of once-daily memantine (20 mg) treatment on cognition and communication in patients with moderate to severe Alzheimer’s disease (AD). In a multicenter, single-arm open-label study, outpatients diagnosed with AD (MMSE < 20; n = 97) were titrated from 5 mg to 20 mg once-daily memantine over 4 weeks. Once-daily […]
MR spectroscopy for assessment of memantine treatment in mild to moderate Alzheimer dementia

Objectives: Magnetic Resonance Spectroscopy (MRS) may provide a precise and reliable assessment of the extent and severity of neural tissue loss caused by various diseases. In particular, the N-Acetyl Aspartate (NAA) and Creatine (Cr) ratio has been found to be an indicator of the degree of neuronal loss in Alzheimer’s disease (AD). Memantine is thought […]
Effects of memantine on clinical ratings, fluorodeoxyglucose positron emission tomography measurements, and cerebrospinal fluid assays in patients with moderate to severe Alzheimer dementia: a 24-week, randomized, clinical trial

Li, Chunbo,
Xiao, Shifu
Most experts consider that memantine has a symptomatic treatment, but clinical trials have not yet provided compelling evidence to support a disease-modifying effect. We investigate the effects of memantine on clinical ratings; fluorodeoxyglucose positron emission tomography (FDG-PET) measurements, which can monitor disease-modifying effect; and cerebrospinal fluid (CSF) assays in patients with moderate to severe probable […]
Akatinol memantine in patients with vascular cognitive disorders
Treatment of cognitive disorders developed in cerebrovascular pathology is an actual medical problem. Of great importance is the timed diagnosis of these changes in the earlier phases of the development of cognitive deficit as well as adequate therapy that can delay and prevent the development of such complication as dementia. Pathogenetic mechanisms of cognitive disorders […]
Efficacy of acatinol memantine in mild cognitive disorder
An open 6 month clinical trial of efficacy of acatinol has been carried out in patients with mild cognitive disorder (MCD). Forty patients received acatinol and 20 patients of comparison group were treated with piracetam. Mean age of patients was 67,7+/-7,2 years. Patient’s state was assessed with a battery of scales, questionnaires and neuropsychological tests. […]

Lazzeroni, L.,
Rasgon, N. L.
Background: To determine the effects of memantine on cognition in a normal population of postmenopausal women with putative risk factors for Alzheimer’s disease (AD) using a built-in control for the genetic risk factor for AD (apoE-epsilon4 status).; Methods: A prospective, open-label, 6-month pilot medication trial with memantine and follow-up after discontinuance conducted at the Center […]
Randomized controlled trial of memantine in dementia associated with Parkinson’s disease
The objective of this study is to investigate the safety and tolerability of memantine, a glutamatergic modulator, in patients suffering from dementia associated with Parkinson’s disease (PDD), an increasingly common complication of PD. This was a 22-week trial of 25 participants with a DSM-IV diagnosis of PDD who were randomized to either placebo or 20 […]
