Methods. Currently there are just five medications – including memantine – which have been approved for the treatment of cognitive decline in Alzheimer’s. For example, a double-blind randomized controlled trial in 80 young adults with opioid dependence treated with buprenorphine and/or naloxone were also given either memantine or a placebo. Our website services, content, and products are for informational purposes only. Glutamate, an excitatory neurotransmitter in the central nervous system (CNS), may play a role in the development of anxiety. The patients also reported experiencing a subjective improvement in their mood, memory, and concentration [17]. This paper evaluates memantine as an augmentation therapy for treatment of anxiety. The other four are all acetylcholinesterase inhibitors, which means that they work primarily by preventing the breakdown of the neurotransmitter acetylcholine. Memantine may improve the ability to think and remember or may slow the loss of these abilities in p… These factors include: individual variation, dosage, time span over which you’ve taken the drug, and whether you’re taking any other drugs or supplements. FDA has approved memantine, as a noncompetitive N-methyl-D-aspartate (NMDA) glutamate receptor antagonist for the treatment of Alzheimer’s disease [6]. The kind of drunk, disoriented, and uncoordinated feeling widely reported by myself and others is what I believe is helping my anxiety. It gives you genetic-based diet, lifestyle and supplement tips that can help improve your cognitive function. Infantile nystagmus (IN) often occurs in the first 3 to 6 months of life. In addition, … Most studies support 20mg a day (or 10mg twice daily) to be the most effective dose [1]. The NMDA receptor antagonist memantine may be an effective augmentation therapy in patients with treatment-resistant anxiety. Having a hard time focusing with all that is going on this year? That said, watch for fatigue, aches, dizziness, nausea, and constipation. However, this effect would need to be studied in human patients to find out for sure whether a similar effect would be seen in humans, and not just mice. Randomized studies are indicated to confirm whether memantine is a novel therapy for ADHD across the lifespan. Read on to learn more about this drug, its mechanisms, side-effects, and more! GAD is characterized by excessive worry or anxiety, which affects a person’s quality of life. Memantine is not a cure for Alzheimer's disease but it can help people with the disease. A plus sign next to the number “[1+, 2+, etc...]” means that the information is found within the full scientific study rather than the abstract. Our goal is to not have a single piece of inaccurate information on this website. Common side effects include headache, constipation, sleepiness, and dizziness. 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. The number of patients who achieved remission (HAM-A ≤7) at endpoint was 4 (40%). Furthermore, memantine caused short-term worsening of neurologic symptoms in MS, thereby exacerbating the cognitive deficits [41]. Memantine has been a godsend for my social anxiety. ), fatigue 20% ( Memantine also blocks 5-HT3 (serotonin subtype 3) receptors. The recommendations are. It is important to note that memantine and other Alzheimer’s drugs do not cure Alzheimer’s – they only slow some of the cognitive decline commonly seen in this disease. This paper evaluates memantine as an augmentation therapy for treatment of anxiety. The number of patients considered responders (reduction of ≥50% in HAM-A total score) at endpoint was 6 (60%). Week 2: 10 mg orally/day (Administer 5 mg twice a day.) Memantine also enhances intracortical inhibition, 23 which is deficient in OCD. All 15 patients (100%) had a diagnosis of generalized anxiety disorder (GAD) while 4 (26%) patients also had comorbid social anxiety disorder, and they all (100%) were using SSRIs at the time of the enrollment with a mean dose of 40 mg/day (Table 1). Finally, memantine may activate dopamine D2 receptors. A pilot open label prospective study of memantine monotherapy in adults with ADHD. Twelve weeks of memantine was reported to slightly decrease anxiety in 7 patients with GAD [22, 23]. Memantine is a drug approved for the treatment of moderate-to-severe Alzheimer’s disease. This medicine is available only … Clinical trials typically use somewhere between 5-40mg per day, often administered in two equal doses spread over the course of the day. Be cautious about risk of falls if memantine causes sedation for the patient. Selfhacked LLC does not provide medical advice, diagnosis, or treatment. 25 There is very little published data of memantine treatment of either OCD or GAD. Another case study of a 56-year-old man who suffered from PTSD, depression, suicidal ideation, insomnia, and cognitive impairment reported an improvement in anger control, concentration, memory, and depression [18]. They usually come in the form of confusion, dizziness, insomnia, or headache. It could be flexibly dosed upwards by 5 mg every week based on effectiveness and tolerability to a maximum dose of 20 mg/day. Our science team is put through the strictest vetting process in the health industry and we often reject applicants who have written articles for many of the largest health websites that are deemed trustworthy. The mean final dose of memantine was approximately 14 mg/day. We are committed to sharing findings related to COVID-19 as quickly as possible. Therefore, it is important to take all of the information below with a healthy grain of salt! Glutamate is felt to play a role in the development of anxiety. The so-called “negative symptoms” of schizophrenia (such as decreased speech and socialization; reduced emotional response) were reduced when memantine was added to antipsychotics [25]. Memantine partially blocks N-methyl-D-aspartate (NMDA) receptors' glutamate channels located in the CNS. Also known as: Namenda, Namenda XR Memantine has an average rating of 5.3 out of 10 from a total of 55 ratings on Drugs.com. My wife was recently prescribed Memantine for headaches. Total daily doses of memantine were divided between morning and evening and taken with food. Some evidence supports the use of memantine in the treatment of PTSD. Two patients discontinued treatment due to moderate adverse events (nausea and dizziness) after their second study visit. ), headaches 30% ( According to studies, “memantine is well tolerated” and only around 1% of patients suffer from memantine side effects. According to one study, sixty patients who took memantine daily for their migraines had an average of 3.4 fewer migraines per month, whereas the placebo group only had 1 less per month [28]. Memantine is in a class of medications called NMDA receptor antagonists. Memantine improved sleep quality. Memantine will not cure Alzheimer's disease, and it will not stop the disease from getting worse. It is also used “off-label” to treat dementia, ADHD, PTSD, and other psychiatric conditions. Other reported side effects include [37]: For patients with severe liver or kidney impairments, clinicians have been advised to prescribe a lower dosage of memantine accordingly. There was no difference in the frequency of side effects between the two treatments [15]. Methods. Memantine as augmentation therapy (mainly to SSRIs) was well tolerated. Nonetheless, like any drug, there is always at least some potential of experiencing adverse side-effects, and so it’s important to be aware of these. Usual Adult Dose for Alzheimer's Disease. Forty percent of patients achieved remission (HAM-A ≥ 7). Its use in other illnesses such as bipolar disorder and autism is currently being explored. Memantine is a medication used to treat moderate-to-severe Alzheimer's disease. As always, the best way to minimize the risk of experiencing adverse reactions from memantine (or any other medication) is to make sure that your doctor is fully aware of any other medications or supplements you are taking, other pre-existing health conditions you have, and any other information that could be relevant to your treatment. Mean outcome trajectories were assessed by implementing a random intercept model to account for the within subject dependency due to assessments over the study period (Figure 1). Our science team must pass long technical science tests, difficult logical reasoning and reading comprehension tests. 6) May Decrease Symptoms of Obsessive-Compulsive Disorder (OCD) According to some studies, memantine has shown some potential when used in addition to first-line treatments for OCD . Demographic and clinical characteristics of patients. Common Questions and Answers about Memantine for anxiety. Memantine partially blocks N-methyl-D-aspartate (NMDA) receptors' glutamate channels located in the CNS. At this point, adding memantine to Ms. A’s regimen of clomipramine (300 mg/day) and sulpiride (400 mg/day) was suggested, and she signed informed consent after explanation of this off-label therapy. 2012, Article ID 749796, 3 pages, 2012. https://doi.org/10.1155/2012/749796, 1Department of Psychiatry, SUNY Upstate Medical University, 750 E.

Therefore, these drugs are useful for improving the daily functioning and quality-of-life of Alzheimer’s patients; but they nevertheless do not reverse the course of the disease once it has started, nor do they fully prevent the disease from progressing over time. Glutamate, an excitatory neurotransmitter, is often in balance with an inhibitory neurotransmitter, GABA. Eight animal groups were used (n = 6 - 8/group), of which three groups received different doses of memantine (1, 2.5, and 5 mg/kg; ip) 30 min before being placed in CB for 60 min while the apparatus was off . On the 5th day the headaches stopped, but now she's constantly … Supposedly memantine works for anxiety by inhibition of glutamate. Dissociative or psychotic patients were excluded. 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 [2]. It is less preferred than acetylcholinesterase inhibitors such as donepezil. Given that memantine has met FDA approval for medical use, the majority of scientific evidence supports the overall safety and effectiveness of memantine. Required fields are marked *. All agreed to be enrolled in an open-label case series where memantine was used adjunctively with their preexisting SSRIs in order to further mitigate their anxiety. ). Memantine also blocks nicotinic receptors [6]. Align your health hacks with your genes for optimal health & cognitive function. It is taken by mouth. -Initial Dose: 7 mg orally once a day. 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 [20]. is a clickable link to peer-reviewed scientific studies. On the other hand, if you reduce glutamate and, presumably, one of its precursors, glutamine, you run the risk of muscle wasting. Objective. For example, an open-label pilot study in 33 bipolar disorder patients hospitalized for mania reported that 21 days of memantine reduced symptoms of mania [19]. Methadone is another medication used to help individuals with opioid use disorder. This was a ten-week, single-center, open-label study for which fifteen patients were enrolled after obtaining Institutional review board approval. This also suggests that this mechanism may not be central to the drug’s main therapeutic effects [7]. Jonathan Ritter, PharmD, PhD (Pharmacology), Flea Bites on Humans & Pets: Symptoms & Treatment, Extended-release (24 hours) 7 mg, 14 mg, 21 mg, and 28 mg capsules. Some studies reported benefit, one case documenting a 100% response [24]. Some guidelines recommended to start patients off at 5mg once daily, and increase (“titrate”) the dose in increments of 5mg every week until reaching a dose of 20mg per day [13, 1, 44]. In another study (double-blind randomized controlled trial) of 26 adults with ADHD, 12 weeks of memantine helped to improve executive functioning when administered with methylphenidate, while the placebo group showed no improvement. We believe that the most accurate information is found directly in the scientific source. The efficacy and safety of memantine in children has not been studied extensively enough for it to be approved for use in younger patients [3]. The important (much rarer) side effects, which caregivers should watch for because of how memantine impacts signals in the brain, are shortness of … Week 4/Maintenance Dose: 20 mg orally/day (Administer 10 mg twice a day.) This medication is only FDA-approved for the treatment of certain specific medical disorders, and can only be taken by prescription and with oversight from a licensed medical professional. Memantine has a small beneficial effect in people with moderate-to-severe AD. Method: Ten OCD and 7 GAD subjects received 12 weeks of open-label memantine 10 mg twice daily, as either monotherapy or augmentation of their existing medication. Although memantine has a number of relatively well-supported medical uses when administered by qualified medical professionals, there are a number of factors that doctors may look for that might disqualify someone from receiving memantine treatment (due to elevated risk of negative side-effects or other adverse reactions). Occasionally, doctors will prescribe drugs like memantine to help treat conditions that fall outside of the official uses approved by the FDA – also known as “off-label” drug use [9, 10, 11]. 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 [13]. 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 [30]. In regards to limitations, this was an open-label consecutive patient case series. Glutamate, the predominant excitatory neurotransmitter in the central nervous system, is thought to play an important role in the pathophysiology of anxiety [4, 5]. male and female outpatients aged 18–65 with a DSM-IV diagnosis of either generalized or social anxiety disorder based on MINI diagnostic interview; rating of at least “moderately ill” (score of 4) on the Clinical Global Impressions of Severity (CGI-S) scale and score of at least 10 on HAM-A and 5 on HADS anxiety subscale; failure to respond adequately to trial of conventional anxiolytic; adequate treatment duration was considered 4 weeks at therapeutic dose; adequate response is defined as an improvement of ≥50% in symptoms of anxiety on current anxiolytic therapy, as measured subjectively by patients or objectively by physician; stable on current psychiatric medication for ≥6 weeks prior to study entry. Memantine may be an effective augmentation therapy in patients with anxiety who remain symptomatic despite adequate treatment with conventional antidepressant anxiolytics. Your email address will not be published. Taking 20mg per day of memantine for 12 weeks reportedly decreased symptoms of inappropriately increased awareness and avoidance in a case series of 4 veterans. Listing a study does not mean it has been evaluated by the U.S. Federal Government. One of the most common “off-label” uses of memantine is to treat other (i.e. However, this same study also reported that there were no apparent benefits of the use in memantine in patients with only mild Alzheimer’s disease [1]. Another study reported a slight improvement or no benefit of memantine in DLB [39]. However, keep in mind that the evidence supporting these potential applications is still only preliminary, and a lot more additional research will be needed before any of these applications are ever officially approved for medical use. Gabapentin is a prescription medication, most commonly sold under the brand name, Neurontin. Mean age was 44 years (range 26–63). Memantine was started at 5 mg/day and titrated to 20 mg/day within 2 weeks. After 28 weeks of memantine treatment, 16 WKS patients were reported to show improvements in both thinking and overall functioning when compared to the placebo group (randomized controlled trial) [14]. The analysis included double-blind, randomized, placebo-controlled trials of memantine in MDD and BD. Memantine is believed to slow the neurotoxicity associated with Alzheimer’s disease and other neurodegenerative diseases [3]. Five patients withdrew consent. Memantine has been reported to reduce the symptoms of IN, as well as improve vision and the ability to angle the eyes in order to focus on objects (foveation) [27]. This site uses Akismet to reduce spam. memantine-like substances that show putative anti-proliferative and autophagic effects on several glioma and medulloblastoma cell lines through NMDAR1.18,19 In a phase I trial,20 memantine was found to be safe when combined with temozolomide, mefloquine, and metformin in patients with glioblastoma.

It has a community prevalence of 2–7%, and a prevalence of around 10% in patients presenting to primary care (Reference Beekman, Bremmer and Deeg Beekman 1998).In people with dementia, however, the rate rises to between 38 … 43% of those users who reviewed Memantine reported a positive effect, while 41% reported a negative effect. Learn how your comment data is processed. In a recent meta-analysis of 28 studies, the combination of donepezil and memantine was reported to significantly improve cognitive function, behavioral and psychological symptoms, and global functions more than donepezil alone, with the same side effects [8]. Memantine partially inhibits N-methyl-D-aspartate (NMDA) glutamate receptors thus dampening synaptic glutamate availability [10]. 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. Memantine was largely well-tolerated and associated with improvement in ADHD symptoms and neuropsychological performance. Future investigations would benefit from placebo-controlled clinical trials to further investigate the true benefits of memantine for the treatment of anxiety. Memantine partially blocks N-methyl-D-aspartate (NMDA) receptors' glutamate channels located in the CNS. Originally developed in the 1960s to treat diabetes, memantine was approved by the FDA in the US in 2003 for the treatment of moderate-to-severe Alzheimer’s disease [1]. In patients with especially severe kidney impairments, it is recommended that dosages not exceed more than 5mg twice daily (10mg/day) [37]. A. Monn, and D. D.

Generalised anxiety disorder is the most common late-life psychiatric disorder. Treatment with memantine significantly decreased the NPI score (5.8±4.3, p <0.01). Dementia of Wernicke-Korsakoff syndrome (WKS) is dementia caused by vitamin B1 deficiency. In preclinical reports and other clinical trials, memantine has been shown to be effective in the treatment of obsessive compulsive and posttraumatic disorders but has never been evaluated for generalized or social anxiety disorders [7–9]. A responder was defined as a patient with a reduction of ≥50% in HAM-A total score. It is generally well-tolerated, and does not appear to cause an unusually high rate of negative side-effects [36]. 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 [43]. Memantine is similar to control in dysphoria, anxiety/phobia, euphoria, apathy, and eating disturbance.Conclusion: The meta-analysis suggest that memantine has benefits for the treatment of most of the behavioral disturbances in patients with Alzheimer’s disease. Memantine augmentation resulted in clinically relevant reduction in anxiety symptoms when compared to baseline. Twelve weeks of memantine was reported to slightly decrease anxiety in 7 patients with GAD [22, 23]. We do not aim to diagnose, treat, cure or prevent any illness or disease. Treating Generalized Anxiety Disorder Symptoms; If you are struggling with anxiety, Memantine may be very helpful for you. This GABA-glutamate balance (when GABA is low and Glutamate is normal to high) is also felt to play a role in the development of generalized or social anxiety disorders. Glutamate, an excitatory neurotransmitter in the central nervous system (CNS), may play a role in the development of anxiety. Week 3: 15 mg orally/day (Administer 5 mg and 10 mg as separate doses.) Then when I realized it was sort of delayed reaction I took it that night. Memantine has warnings in those with kidney and liver dysfunction or impairment [3]. Some evidence suggests that memantine may have potential as a complementary medication to help treat addiction and other substance use disorders (meaning that it is used together with other, more “conventional” drugs – and not used just on its own). In the context of dementia treatment, the specific form of dementia that has the most evidence to support it is vascular dementia. Result. namenda. Memantine (Namenda) is an N-methyl-D-aspartate (NMDA) glutamate receptor antagonist that is FDA-approved for the treatment of Alzheimer’s dementia. Muscle spasms are another common symptom of MS, causing discomfort and decreasing quality of life. Similarly mean HAD-A dropped from baseline value of 13.2 to 8.4. Usually, this is done because there is actually decent evidence that the drug may help, although this evidence might not be quite strong enough to get full FDA approval (which generally has very strict requirements). 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) [4]. The memantine group was reported to be significantly less likely to relapse compared to the placebo group, as observed over the course of eight weeks [31]. Acquired fixational pendular nystagmus (APN) is a type of eye condition where eyes make repetitive uncontrolled movements that appear as excessive motion, and which blurs the patient’s vision. There were 15 patients enrolled for the study, 11 females and 4 males. The mean MMSE and NPI scores were 22.6±3.4 and 13.8±12.9, respectively. Nine patients (60%) were mild to moderately ill, while 6 patients (40%) were markedly ill at the baseline visit according to the CGI scale. Memantine for anxiety. Memantine’s main mechanism is through glutamate NMDA receptor inhibition in the brain. However, Gabapentin for anxiety is becoming increasingly popular. … The FDA has officially approved memantine for the treatment of certain cases of Alzheimer’s disease, and this is the most typical medical use of memantine. Memantine was listed as a category B in the old FDA pregnancy risk ratings for drugs. Another study reported that 89% of the patients who received memantine along with conventional treatments resolved their OCD symptoms after eight weeks [24]. Patients with at least one postbaseline efficacy measurement were included in the efficacy dataset and analyzed using the last-observation-carried-forward (LOCF) technique. In a study (double-blind randomized controlled trial) of 548 patients with vascular dementia, those treated with memantine for 28 weeks were reported to score significantly higher on their mini-mental status exam (a clinical test that is used to assess the progression of cognitive decline, especially in dementia) compared patients on placebo [12]. We have written this post for informational purposes only, and our goal is solely to inform people about the science behind memantine’s effects, mechanisms, and current medical uses. SelfHacked © 2013 – 2021 All Rights Reserved, If you’re interested in natural and targeted ways of improving your cognitive function so that you can perform optimally despite all the negative news around you, we recommend checking out, . Animal reproduction studies have shown adverse events, and patients are advised to use memantine with caution before- or during pregnancy [3]. The authors feel that memantine, given its ability to manipulate the GABA-glutamate balance by lowering glutamate without major side effects (weight gain, sexual problems, (i.e., SSRI/SNRI), or addiction (i.e., sedatives)), may be a reasonable add-on or augmentation strategy to better alleviate anxiety in SNRI or SSRI partial responders. 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 [32]. Memantine has been reported to increase the concentration of sertraline (an antidepressant) in the brains of mice. Seven patients completed the trial fully. There were significant decreases in the scores of subscales for anxiety (p =0.04) and irritability/lability (p =0.04). Once again, however, this effect has not yet been directly observed in any human populations, so it’s too early to know how much potential memantine might have in the medical treatment of ALS. ), and increased dream activity 20% ( Join SelfHacked today and start the journey of improving your life. However, there are also several other types of dementia that have evidence to support the use of memantine in treatment, and it’s not uncommon for doctors to prescribe memantine as a part of the treatment for patients with these conditions. Anxiety disorders are some of the most occurring forms of psychiatric disorders seen in clinical practice and are associated with a 1-year prevalence rate of 12% in adults [1]. Given memantine’s ability to lower glutamate activity, it may be able to also lower anxiety without the need for a sedative medication. The information on this website has not been evaluated by the Food & Drug Administration or any other medical body. Although this effect has not been studied directly in humans, at least one animal study has reported that treating mice with memantine after they experienced repetitive mild traumatic brain injury showed less extensive damage to their brains compared to controls [34]. In some extreme cases they come with hallucinations, but this is rare. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. Anxiety from memantine or naltrexone? Memantine is used to treat the symptoms of Alzheimer's disease (AD; a brain disease that slowly destroys the memory and the ability to think, learn, communicate and handle daily activities). Augmentation therapy is a common approach to managing patients who remain symptomatic despite adequate treatment with conventional antidepressant anxiolytics [3]. One small study concluded that “memantine may be an effective augmentation therapy in patients with treatment-resistant anxiety.” 14 Main eligibility criteria included:(i)male and female outpatients aged 18–65 with a DSM-IV diagnosis of either generalized or social anxiety disorder based on MINI diagnostic interview;(ii)rating of at least “moderately ill” (score of 4) on the Clinical Global Impressions of Severity (CGI-S) scale and score of at least 10 on HAM-A and 5 on HADS anxiety subscale;(iii)failure to respond adequately to trial of conventional anxiolytic;(iv)adequate treatment duration was considered 4 weeks at therapeutic dose;(v)adequate response is defined as an improvement of ≥50% in symptoms of anxiety on current anxiolytic therapy, as measured subjectively by patients or objectively by physician;(vi)stable on current psychiatric medication for ≥6 weeks prior to study entry.
