Evaluation of the Safety and Efficacy of Memantine as Adjunctive Treatment in Schizophrenia Patients

Standard antipsychotic drug regimens do not fully address the impact of cognitive symptoms associated with schizophrenia. The NMDA receptor has been connected to the pathophysiology of schizophrenia. Memantine is an uncompetitive NMDA receptor antagonist. It is hypothesized that adjunctive therapy with memantine will reduce NMDA receptor hyperactivity, improving signal to noise ratio and thereby improving cognitive symptoms.

Memantine Treatment for Obsessive-Compulsive Disorder and Generalized Anxiety Disorder

The objective of this study was to obtain preliminary open-label data on the efficacy and tolerability of memantine, an anti-glutamatergic medication with a unique pharmacodynamic profile, in individuals with OCD and individuals with GAD. Because glutamatergic hyperactivity in frontal and frontal-subcortical circuits may play a role in the symptomatic expression of OCD, and possibly GAD, agents that reduce glutamatergic neurotransmission should provide unique anti-stress and an...

Biomarker Study of Acamprosate in Schizophrenia

NMDA receptors are brain receptors that are stimulated by glutamate. Poorly functioning NMDA receptors are thought to be involved in the pathology of schizophrenia. This hypothesis is based on the observation that PCP, which blocks the NMDA receptor, produces symptoms and cognitive impairments similar to schizophrenia. Efforts to enhance the function of the NMDA receptor with glycine and D-cycloserine have met with limited success. An alternative approach would be to use the...

Nitrous oxide, a member of the NMDA receptor antagonist class, is a widely-used general anesthetic and sedative with a proven safety profile. The investigators hyp...


Multicenter and Prospective Clinical Registry Study of Autoimmune Encephalitis in China

In recent years, more and more previously thought to be unknown encephalitis was found to be a specific antigen associated encephalitis,but because of the lack of recognition in the clinic, usually been misdiagnosed as other causes of encephalitis. Therefore, it is urgent to establish a database of autoimmune encephalitis in Chinese population. The prospective clinical trial of atutoimmune encephalitis in China, by screening the autoimmune encephalitis associated antibody and...

The Safety and Efficacy of Neramexane in Patients With Moderate to Severe Alzheimer's Disease

Memory loss and difficulties with thinking associated with Alzheimer's disease may be due to chronic release of a brain chemical called glutamate. Glutamate helps transmit messages between nerve cells through interaction with a certain type of receptor (N-methyl-D-aspartate, NMDA) on the cell. Neramexane is a new drug that blocks the effects of excessive glutamate at the receptor (NMDA receptor antagonist).

Post-market Study of AMAP Receptor Antagonists for Epilepsy Patients in Hong Kong

Background: Epilepsy is a chronic neurological disease which affects approximately 70,000 patients in Hong Kong and 50 billion people worldwide. Among these patients one-third remained unresponsive to antiepileptic agents. Continual drug manipulation is an essential therapeutic option for these patients with refractory epilepsy. In particular, rational polytherapy has become the mainstay of treatment for the sub-group of patients who have failed two or more antiepileptic...

Investigation of the NMDA Antagonist Ketamine as a Treatment for Tinnitus

Tinnitus, or ringing in the ears, is a very common problem that often accompanies hearing loss. It affects up to 1 in 10 adults, and about 30% of people who experience chronic tinnitus find it very distressing. In these patients, symptoms of depression and anxiety often accompany tinnitus and there are no approved treatments. Clinical trials are ongoing to test a glutamate NMDA receptor antagonist (called esketamine), which is injected into the inner ear. However, the prelimina...

Treatment of Japanese Encephalitis

Japanese encephalitis is the single largest cause of viral encephalitis in the world today. It occurs in yearly post monsoon outbreaks in Uttar Pradesh and other parts of India and south east Asia. There is presently no antiviral drug of proven benefit for this illness and treatment is mostly supportive. The drug Ribavirin is already in the market in use for other indications. It has been found useful in West Nile encephalitis and various hemorrhagic fevers caused by related ar...

Memantine for the Treatment of Cognitive Impairment in Systemic Lupus Erythematosus

A phenome-wide association study (PheWAS) identified an association between a variant in the human gene for the N2A subunit of the N-methyl-D-aspartate (NMDA) receptor, GRIN2A, and Systemic Lupus Erythematosus (SLE). A single nucleotide polymorphism (SNP) in this gene encodes for increased NMDA receptor activity. Based on the potential function of the associated SNP and published literature, alterations in SNP function signaling may underlie a cluster of symptoms. The objective...

The Antidepressant Effects Of The NMDA Antagonist, CP-101,606, In Patients With MDD

To determine if the NMDA antagonist, CP-101,606, is effective for depression

Mineralocorticoid Receptor, NMDA Receptor and Cognitive Function in Depression

The steroid hormone cortisol is released in response to stress and acts in the central nervous system upon glucocorticoid (GR) and mineralocorticoid receptors (MR). GR are widely distributed across the brain while MR are predominantly expressed in the hippocampus and prefrontal cortex - two brain areas closely related to memory and executive function. Stimulation of MR leads to an increase of glutamate that act on glutamatergic NMDA receptors in the hippocampus and prefrontal c...

Patients with schizophrenia, depression and healthy controls participated in this study. The Investigators found that...

The Influence of Glutamate on Memory in Humans

The hippocampus is particularly laden with n-methyl-d-aspartate (NMDA) receptors, and is at the same time one of the most important sites in declarative memory. The rationale of this study is that the NMDA partial agonist D-Cycloserine will promote learning compared to a placebo. On the other hand, the NMDA receptor antagonist Memantine might lead to reduced memory. We believe that the influence of NMDA receptors on memory can be determined via acute co-activation of the NMDA r...
