Study of Depression-Ketamine-Brain Function

2014-08-26 22:13:14 | BioPortfolio


Targeting the glutamatergic system to treat depression is a new and promising strategy based on studies at the molecular, synaptic, and neuronal level but also on results of studies conducted in animal models and first clinical studies involving depressed patients.Ketamine has been proposed as a novel approach to induce rapid antidepressant response. In this pilot project the investigators aim to introduce this novel and promising approach into clinical practice. Besides the assessment of clinical efficacy, the investigators will put a special emphasis on the assessment of ketamine-associated effects on brain function using fMRI and cognitive testing.

Ketamine Plus Lithium in Treatment-Resistant Depression

The purpose of this study is to test the antidepressant effect of ketamine when given repeatedly over a period of 1 week, as well as the use of Lithium as a relapse-prevention strategy for...

Ketamine for Depression: An MRI Study

Ketamine has been shown to decrease symptoms of anxious depression quickly. This decrease has been shown to last for up to one month. MRI technology will be used before and after ketamine ...

Ketamine and Scopolamine Infusions for Treatment-resistant Major Depressive Disorder

Ketamine infusions resulted in an acute reduction in global depression scores and in severity of suicidal ideation. Scopolamine infusions produced also a significant improvement in depress...

Ketamine for Treatment Resistant Late-Life Depression

The purpose of this study is to examine the effectiveness of a single infusion of ketamine, to determine which dose is optimal and lasts the longest, and to learn about how ketamine works ...

Administration of Subanesthetic Dose of Ketamine and Electroconvulsive Treatment for Treatment Resistant Depression

In this proof of concept study, the investigators plan to administer iv ketamine interleaved with ECT days. Patients with treatment resistant depression who are deemed to be eligible for ...

Ketamine-induced affective switch in a patient with treatment-resistant depression.

There is growing evidence to support the rapid, albeit short-lived antidepressant effect of subanesthetic dose of ketamine, a noncompetitive glutamate N-methyl-D-aspartate receptor antagonist in treat...

Single-Dose ketamine followed by daily D-Cycloserine in treatment-resistant bipolar depression.

To the Editor: Bipolar depression is a leading cause of disability in the United States. Recently, N-methyl-D-asparate glutamate-receptor (NMDAR) antagonists, such as ketamine, have been shown to indu...

Low-Dose Ketamine in Chronic Critical Illness.

We report a case series on the observed effects of low-dose ketamine infusions in 4 critically ill patients with varying complications related to prolonged critical illness. Doses of ketamine infusion...

Ketamine Users Have High Rates of Psychosis and/or Depression.

Ketamine has been linked to psychosis and used in the treatment of depression. However, no study has examined the prevalence of psychotic and depressive disorders in dependent ketamine users. This stu...

The positive effect on ketamine as a priming adjuvant in antidepressant treatment.

Ketamine is an anesthetic with antidepressant properties. The rapid and lasting effect of ketamine observed in preclinical and clinical research makes it a promising therapeutic to improve current maj...

Medical and Biotech [MESH] Definitions

A cyclohexanone derivative used for induction of anesthesia. Its mechanism of action is not well understood, but ketamine can block NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE) and may interact with sigma receptors.

Depressive states usually of moderate intensity in contrast with major depression present in neurotic and psychotic disorders.

A hallucinogen formerly used as a veterinary anesthetic, and briefly as a general anesthetic for humans. Phencyclidine is similar to KETAMINE in structure and in many of its effects. Like ketamine, it can produce a dissociative state. It exerts its pharmacological action through inhibition of NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE). As a drug of abuse, it is known as PCP and Angel Dust.

The prototypical tricyclic antidepressant. It has been used in major depression, dysthymia, bipolar depression, attention-deficit disorders, agoraphobia, and panic disorders. It has less sedative effect than some other members of this therapeutic group.

A propylamine formed from the cyclization of the side chain of amphetamine. This monoamine oxidase inhibitor is effective in the treatment of major depression, dysthymic disorder, and atypical depression. It also is useful in panic and phobic disorders. (From AMA Drug Evaluations Annual, 1994, p311)
