BACKGROUND Proper management of depression in elderly population would improve the outcome of the disease and reduce its related disability and mortality. Use of memantine with minimal side effects and drug interaction seems reasonable in the elderly but its antidepressant activity is controversial. The aim of the current research is to investigate the effects of add-on memantine during citalop...
Memantine, an N-methyl-D-aspartate (NMDA) receptor antagonist, has been shown to improve learning and memory in several preclinical models of Alzheimer's disease (AD). Memantine has also been shown to reduce the levels of amyloid beta (A beta) peptides in human neuroblastoma cells as well as to inhibit A beta oligomer-induced synaptic loss. In this study, we assessed whether NMDA receptor inhib...
BACKGROUND This is the first meta-analysis to compare the treatment effects and safety of administering donepezil alone versus a combination of memantine and donepezil to treat patients with moderate to severe Alzheimer Disease, particularly regarding cognitive functions, behavioral and psychological symptoms in dementia (BPSD), and global functions. METHODS PubMed, Medline, Embase, PsycINFO,...
INTRODUCTION Patients with idiopathic normal pressure hydrocephalus often show neuropsychiatric symptoms besides the triad of 'classic' symptoms. Memantine has been reported to have positive effects on the neuropsychiatric symptoms of patients with Alzheimer's disease and patients with dementia with Lewy bodies. We administered memantine to a Japanese patient with probable idiopathic normal pre...
The hippocampus is a complex network tightly regulated by interactions between excitatory and inhibitory neurons. In neurodegenerative disorders where cognitive functions such as learning and memory are impaired this excitation-inhibition balance may be altered. Interestingly, the uncompetitive N-methyl-d-aspartate receptor (NMDAR) antagonist memantine, currently in clinical use for the treatme...
OBJECTIVE Most investigations of pharmacotherapy for treating Alzheimer's disease focus on patients with mild-to-moderate symptoms, with little evidence to guide clinical decisions when symptoms become severe. We examined whether continuing donepezil, or commencing memantine, is cost-effective for community-dwelling, moderate-to-severe Alzheimer's disease patients. METHODS Cost-effectiveness ...
Low-dose memantine might have anti-inflammatory and neurotrophic effects mechanistically remote from an NMDA receptor. We investigated whether add-on memantine reduced cytokine levels and benefitted patients with opioid dependence undergoing methadone maintenance therapy (MMT) in a randomized, double-blind, controlled 12-week study. Patients were randomly assigned to a group: Memantine (5 mg/da...
There is preclinical support for using NMDA receptor glutamatergic antagonists to aid in naltrexone-based treatment of opioid dependence. We hypothesized that adding memantine will improve efficacy of extended-release (XR) naltrexone to prevent relapse. In this double blind study opioid-dependent participants (N=82) underwent inpatient detoxification and naltrexone induction. During naltrexone ...
Hippocampal learning is thought to induce metaplasticity, which can facilitate subsequent learning. Administered at single low doses, the N-methyl-d-aspartate-type glutamate receptor antagonist memantine predominantly blocks α7 nicotinic acetylcholine receptors (α7 nAChRs). Placebo-controlled administration of a single low dose of memantine in a pharmaco-fMRI experiment may thus help characteri...
BACKGROUND Given that memantine is thought to decrease N-methyl-D-aspartic-acid-related (NMDA) glutamatergic hyperactivity and improve locomotion in rats, we sought to assess the drug's impact on axial symptoms in advanced Parkinson's disease (PD). METHODS We performed a 90-day, randomised, double-blind, study with two parallel arms: 20 mg/day memantine versus placebo (ClinicalTrials.gov:NCT0...
