This paper evaluates memantine as an augmentation therapy for treatment of anxiety. Memantine quickly binds to and blocks NMDA receptors, which can counteract toxicity caused by too much excitation (excitotoxicity), and thereby prevents programmed cell death (apoptosis) . It is also used “off-label” to treat dementia, ADHD, PTSD, and other psychiatric conditions. It works by decreasing abnormal activity in the brain. This paper evaluates memantine as an augmentation therapy for treatment of anxiety. Then when I realized it was sort of delayed reaction I took it that night. ), fatigue 20% ( The recommendations are personalized based on YOUR DNA. When memantine was combined with methadone, the two medications reportedly decreased the total amount of methadone needed to curb individuals’ craving for opioids over the course of 12 weeks of treatment . It is taken by mouth. This has only been studied in cell lines where memantine does bind to D2 receptors; however, its action is very short-lived, making it difficult to measure. Mean dose was 14 mg/d (range 5–20 mg/d). Seven patients completed the trial fully. This was assessed using the Clinician’s Interview-Based Impression of Change Plus Caregiver Input (CIBIC-Plus), the Alzheimer’s Disease Cooperative Study Activities of Daily Living Inventory modified for severe dementia (SDCS-ADLsev), and the Severe Impairment Battery, all of which are used by clinicians to measure diverse aspects of cognitive function and behavior in Alzheimer’s patients . SelfHacked has the strictest sourcing guidelines in the health industry and we almost exclusively link to medically peer-reviewed studies, usually on PubMed. In 28 patients with refractory migraines, memantine taken daily reportedly helped to decrease the number of days with a headache from 22 per month to 16 days per month . This also suggests that this mechanism may not be central to the drug’s main therapeutic effects .

One case study of a bipolar patient resistant to conventional treatment reported that 10 mg/day of memantine for 4 weeks resulted in a complete disappearance of manic symptoms . It is less preferred than acetylcholinesterase inhibitors such as donepezil. Learn which genes are key players in cognitive function and what you can do to optimize them. Conclusion. Memantine also helps with severe dementia as well as dementia of WKS (Wernicke-Korsakoff Syndrome), but the results have not been as impressive as they are with vascular dementia. In a randomized controlled trial in 250 patients, memantine for 28 weeks slowed cognitive and functional decline compared to placebo in moderate-to-severe Alzheimer’s. We conducted a systematic review and meta-analysis on whether memantine was beneficial for the treatment of depressive symptoms in major depressive disorder (MDD) and bipolar disorder (BD). Another study reported a slight improvement or no benefit of memantine in DLB . What does the science have to say about how it works and what it does? Too little or too much glutamate can lead to cell death. Memantine has a small beneficial effect in people with moderate-to-severe AD. All patients in this paper suffered from either social anxiety disorder (SAD) or generalized anxiety disorder (GAD). Consequently, there is a large pool of high-quality evidence that supports memantine’s use in moderate-to-severe cases of Alzheimer’s disease (AD). Week 3: 15 mg orally/day (Administer 5 mg and 10 mg as separate doses.) In a study (randomized controlled trial) of 166 patients with severe dementia in either Alzheimer’s or vascular dementia, the group treated with memantine were reported to show better functional outcomes, and were less dependent on their caregivers, after 12 weeks of treatment with memantine . Bipolar disorder is a mental disorder characterized by periods of both elevated mood (mania) and depression, and some evidence exists that suggests that memantine may be helpful in treating some of its associated symptoms.

On the other hand, if you reduce glutamate and, presumably, one of its precursors, glutamine, you run the risk of muscle wasting. Twelve weeks of memantine was reported to slightly decrease anxiety in 7 patients with GAD [22, 23]. Our team comprises of trained MDs, PhDs, pharmacists, qualified scientists, and certified health and wellness specialists.

Another study reported that 89% of the patients who received memantine along with conventional treatments resolved their OCD symptoms after eight weeks . Dementia of Wernicke-Korsakoff syndrome (WKS) is dementia caused by vitamin B1 deficiency. There is the possibility of experiencing adverse side-effects or interactions: therefore it is important that you are continually monitored by your doctor while taking memantine. Given memantine’s ability to lower glutamate activity, it may be able to also lower anxiety without the need for a sedative medication. Selective serotonin reuptake inhibitors (SSRIs) are commonly used for the treatment of anxiety disorders; however, complete resolution of symptoms may only be seen in approximately 50% of patients . Some studies reported benefit, one case documenting a 100% response . Remission was defined as an HAM-A total score ≤7. 15 consecutive partially responding anxious patients were treated with adjunctive memantine for 10 weeks. Its use in other illnesses such as bipolar disorder and autism is currently being explored. Memantine as augmentation therapy (mainly to SSRIs) was well tolerated. Ms. Finally, memantine may activate dopamine D2 receptors. Some researchers have therefore hypothesized that combining memantine with antidepressants could enhance their potency and effects, although much more clinical research would be needed in order for this to become a part of standard medical practice .
