Molecules, Vol. 28, Pages 3181: Scutellarin Alleviates Ischemic Brain Injury in the Acute Phase by Affecting the Activity of Neurotransmitters in Neurons
In this study, the protective effects of scutellarin on ischemic brain damage in the acute phase (within 12 h) were illustrated. In middle cerebral artery occlusion and reperfusion (MCAO/R) modeling rats, the Z-Longa score was significantly down-regulated by 25% and 23.1%, and the brain infarct size was reduced by 26.95 ± 0.03% and 25.63 ± 0.02% when responding to high-dose and low-dose scutellarin treatments, respectively. H&E and TUNEL staining results indicated that the neuron loss of the ischemic region was improved under scutellarin treatment. In order to investigate the mecha...

Treatment of Vascular and Neurodegenerative Forms of Cognitive Impairment and Dementias
Ideally, dementia care should be provided by a collaborative team. Eligible patients should be treated with the cognitive-enhancing medications, the cholinesterase inhibitors and memantine. For most of the common causes of dementia, there are no disease-modifying medications, with the exception that vascular dementia can be prevented by treating vascular risk factors to prevent stroke. There is hope that Alzheimer disease can be treated by using monoclonal antibodies that target amyloid beta, although more trials are needed. Holistic, patient-centered care can enhance quality and extend the time that the patient can live s...

Targeting organic cation transporters at the blood-brain barrier to treat ischemic stroke in rats
Exp Neurol. 2022 Jul 26:114181. doi: 10.1016/j.expneurol.2022.114181. Online ahead of print.ABSTRACTDrug discovery and development for stroke is challenging as evidenced by few drugs that have advanced beyond a Phase III clinical trial. Memantine is a N-methyl-d-aspartate (NMDA) receptor antagonist that has been shown to be neuroprotective in various preclinical studies. We have identified an endogenous BBB uptake transport system for memantine: organic cation transporters 1 and 2 (Oct1/Oct2). Our goal was to evaluate Oct1/Oct2 as a required BBB mechanism for memantine neuroprotective effects. Male Sprague-Dawley rats (200...

Beneficial effects of memantine on ischemia/reperfusion injury following torsion/detorsion induced testicular damage in rats: Improvement in histological and biochemical parameters
Testicular torsion is a common urologic emergency and one of the causes of infertility in males. Hence, prompt diagnosis and treatment are important to prevent testicular damages. It has been reported that memantine, a drug for Alzheimer's disease has anti-oxidative role against cerebral ischemic stroke and cardiac ischemia reperfusion.

Memantine, NMDA Receptor Antagonist, Attenuates ox-LDL-Induced Inflammation and Oxidative Stress via Activation of BDNF/TrkB Signaling Pathway in HUVECs
AbstractAtherosclerosis is a chronic cardiovascular disease and contributes to pathogenesis of most myocardial infarction and ischemic stroke. Additionally, N-methyl-d-aspartate (NMDA) receptor plays a crucial role in myocardial infarction and ischemic strokes. The aim of our study was to investigate the underlying mechanisms of memantine (MEM), the blocker of NMDA receptors, in the development of atherosclerosis. In our study, human umbilical vascular endothelial cells (HUVECs) were stimulated with low-density lipoprotein (ox-LDL) to establish an atherosclerotic cell model. Cell Counting Kit-8 (CCK-8) assay and TUNEL stai...

Considerations and Current Trends in the Management of the Geriatric Patient on a Consultation –Liaison Service
AbstractPurpose of ReviewTo provide consultation –liaison psychiatrists with an updated resource that can assist in the treatment and management of geriatric patients.Recent FindingsThe current available literature has not shown any differences in efficacy between haloperidol and second-generation antipsychotics in patients with delirium. When considering relative advantages of forms of antipsychotic administration, there is no support for a superior safety profile of oral compared to intramuscular or intravenous administration. A recent meta-analysis of four randomized controlled trials concluded that when melatonin was...

Amantadine and memantine: a comprehensive review for acquired brain injury.
Authors: Ma HM, Zafonte RD Abstract This comprehensive review discusses clinical studies of patients following brain injuries (traumatic, acquired, or stroke), who have been treated with amantadine or memantine. Both amantadine and memantine are commonly used in the acute rehabilitation setting following brain injuries, despite their lack of FDA-approval for neuro-recovery. Given the broad utilization of such agents, there is a need to review the evidence supporting this common off-label prescribing. The purpose of this review is to describe the mechanisms of action for memantine and amantadine, as well as to compl...

Abolition of aberrant neurogenesis ameliorates cognitive impairment after stroke in mice
Poststroke cognitive impairment is considered one of the main complications during the chronic phase of ischemic stroke. In the adult brain, the hippocampus regulates both encoding and retrieval of new information through adult neurogenesis. Nevertheless, the lack of predictive models and studies based on the forgetting processes hinders the understanding of memory alterations after stroke. Our aim was to explore whether poststroke neurogenesis participates in the development of long-term memory impairment. Here, we show a hippocampal neurogenesis burst that persisted 1 month after stroke and that correlated with an impair...

Correlation of stroke and dementia with death: A study from the Swedish dementia registry
(Bentham Science Publishers) Patients who died of IS the most common type of dementia was vascular dementia while those died from other causes were most often diagnosed with Alzheimer's dementia (AD). Patients who died from IS and were registered in Riksstroke had higher MMSE score compared to other groups. Patients who died from IS took more cardiovascular medications. There were no differences in the use of antipsychotics, antidepressants, acetylcholinesterase inhibitors, memantine, anxiolytics, or hypnotics between the groups.

Stroke as a cause of death in death certificates of patients with dementia: a cohort study from the Swedish Dementia Registry.
CONCLUSIONS: There was relatively high number of patients that died from IS in their death certificate but had not been registered in Riksstroke in the year before death. This creates concerns on the accuracy of death certificate stroke diagnoses, particularly for deaths taking place outside of hospitals. PMID: 30280666 [PubMed - as supplied by publisher]

Targeting nitric oxide and NMDA receptor-associated pathways in treatment of high grade glial tumors. Hypotheses for nitro-memantine and nitrones
Publication date: Available online 13 October 2017Source: Nitric OxideAuthor(s): Meric A. Altinoz, İlhan ElmaciAbstractGlioblastoma multiforme (GBM) is a devastating brain cancer with no curative treatment. Targeting Nitric Oxide (NO) and glutamatergic pathways may help as adjunctive treatments in GBM. NO at low doses promotes tumorigenesis, while at higher levels (above 300 nM) triggers apoptosis. Gliomas actively secrete high amounts of glutamate which activates EGR signaling and mediates degradation of peritumoral tissues via excitotoxic injury. Memantine inhibits NMDA-subtype of glutamate receptors (NMDARs) and induc...

The efficacy and safety of pharmacological treatments for post-stroke aphasia.
Conclusions Current evidence suggests that drugs can improve the prognosis of post-stroke aphasia, such as donepezil, memantine. Donepezil has a significant effect in improving the ability of auditory comprehension, naming, repetition and oral expression. Memantine has a significant effect in improving the ability of naming, spontaneous speech and repetition. Bromocriptine showed no significant improvement in the treatment of aphasia after stroke. The trial for galantamine, amphetamine and levodopa in the treatment of aphasia after stroke is limited and inconclusive. PMID: 29984673 [PubMed - as supplied by publisher]
