Does Metformin Cause Dementia?
Metformin is an antidiabetic drug and there has been ongoing debate about its risk with dementia. Some studies have pointed out that there is a reduced dementia risk with metformin, other studies have found no correlation between the two.
There are a few population-based studies that have pointed out the relationship between metformin and dementia. A study published in the Journal of Alzheimer’s Disease has showcased that the use of metformin has actually reduced the risk of dementia in type 2 diabetic patients. However, the Journal of Clinical Endocrinology and Metabolism has shown that metformin is not associated with dementia risk in type 2 diabetes patients.
It is still not understood how metformin affects cognitive health. Metformin is said to inhibit gluconeogenesis in the liver and is said to lower blood glucose. It helps affect the neuroprotective side of the brain.
Metformin’s Impact On Brain Metabolism
There are a few ways metformin affects glucose metabolism in the brain. The Journal of Alzheimer’s Disease has stated that using metformin has improved glucose metabolism in patients with mild Alzheimer’s disease, diabetes, or mild cognitive impairment (MCI). To add on, the study in the Journal of Clinical Endocrinology and Metabolism stated that metformin helped improve insulin sensitivity and glucose metabolism in type 2 diabetes patients. By understanding the brain, it is also important to start doing brain exercises to prevent Alzheimer’s.
Implications For Cognitive Health
Though there are studies that link the use of metformin with the benefits of cognitive health, especially in patients with type 2 diabetes, more research is needed to fully understand its relationship with dementia. It is still unclear what the required dosage and duration are for using metformin. Thus, further research is needed to understand the biological impact.
Comparing Dementia Causality Rates In Metformin Users Vs. Non-Users
There are a few mixed findings between metformin and dementia casualty rates. This is because some observational studies have stated that metformin helps lower dementia risk. However, others have found that there is no association with dementia. A study that used a causal inference approach showed that metformin showed a lower hazard of all-cause mortality and a lower hazard of dementia onset. Another study showed that patients who did not receive pharmacological treatment had a lower risk of dementia. However, there is another study that showed a slower decline in delayed memory and the link with metformin over time.
Study Design And Methods
There have been studies using various designs to show the link between metformin and dementia in users and non-users. A case study showed an association between long metformin use and a higher risk of developing Alzheimer’s Disease. However, there were no dose effects observed. However, another study used randomized controlled trials (RCTs) to study the effect of metformin on dementia and it showed the efficacy of metformin in preventing dementia. Data from many sources, such as electronic health records, medical claims databases, and clinical trials, has been studied to find the link between the use of metformin and the risk of dementia.
Key Findings And Implications
- Whether the researcher influenced the findings and whether there are any actions that can be taken into account.
- There needs to be a discussion about the implications rather than a separate section for it.
- To specify the theoretical and practical implications of the findings, such as social, political, technological, and policy-related.
What Is The Link Between Diabetes And Dementia?
Some studies have stated that people with diabetes mellitus have a higher risk of getting dementia compared to those without diabetes. It is not clearly understood how diabetes affects the rate of dementia, but it is believed to be tied to insulin resistance, inflammation, and oxidative stress.
The relationship between metformin therapy and the risk of dementia is complex, as the medication is primarily used for patients with type 2 diabetes. A meta-analysis study found that metformin use reduced dementia risk in patients with type 2 diabetes with a hazard ratio of 0.707. Another study showed a hazard ratio of 0.554 for those using metformin with reduced dementia risk in type 2 diabetes patients.
There has also been a study between the use of metformin and the risk of those who do not have diabetes. A study showed that there was no correlation between metformin use and dementia risk in those who were non-diabetic.

Does Metformin Cause Alzheimer's Disease?
The relationship between metformin and Alzheimer’s Disease is a topic of research and ongoing debate, as studies have shown positive and negative effects of using it. Here are some highlights and contrasting outcomes.
There have been studies showing the benefits of metformin in people with type 2 diabetes and the role of APOE carrier status. It showed metformin showed better cognitive memory. Another study found that high-dose metformin was linked with improved cognitive function and reduced amyloid-β levels in patients with MCI and early Alzheimer’s Disease.
However, there are studies that show the contrast of metformin use in patients who have been diagnosed with type 2 diabetes. The research showed that metformin increased the risk of Alzheimer’s Disease in the patients. It also indicated that long-term use of metformin reduced vitamin B12, which could be a risk factor for Alzheimer’s Disease.
Though there are some studies that show the benefits of metformin in having a protective effect against Alzheimer’s Disease, there has been other research that states otherwise. Therefore, the link between metformin and Alzheimer’s Disease is complex, and it could be due to factors such as age, genetics, and other health conditions. Thus, more research is needed to fully understand the link between metformin and Alzheimer’s Disease.
Can Metformin Increase The Risk Of Alzheimer’s Disease?
A meta-analysis of 14 studies found metformin reduced dementia risk in type 2 diabetes patients. Another study found that long-term use of metformin increased the risk of dementia in elderly diabetic patients.
Can Metformin Cause Cognitive Decline?
General cognitive effects show that those with type 2 diabetes state that metformin may help to improve memory, attention, speed processing, decision-making, and problem-solving. Though there seem to be benefits, long-term usage of metformin will increase mitochondrial function, which also affects cognitive function, causes hypoglycemia, and leads to insulin resistance, which may contribute to cognitive decline.

View Our LightDoes Metformin Cause Memory Loss?
As stated, metformin is widely used as a drug for type 2 diabetes patients. However, there seem to be both good and bad effects on the use of the medication with memory.
Though some studies have indicated that metformin may help to improve cognitive function, there have been other concerns that it causes memory loss.
The short-term effects that metformin has on memory can be seen in Diabetes Care which states that metformin is associated with improved memory functions. This is seen in patients with type 2 diabetes and there is an increase in their attention and executive function. Another study showed that metformin has improved cognitive function in patients with MCI.
On the other hand, taking metformin is linked to problems, like a higher risk of dementia in older adults. Another study from the journal Neurology showed that long-term metformin use in older adults showed a higher risk of cognitive decline.
One theory is that metformin may improve insulin sensitivity, which helps with improved brain function, while the other states that metformin may reduce inflammation and oxidative stress. On the other hand, some studies have shown that metformin may interact with the APOE gene, which is linked to a reduced risk of dementia. These studies seem to be inconclusive at present. Hence, it is essential to ensure sensory activities for dementia patients.
Does Metformin Affect Mental Health?
There may be mixed evidence when it comes to metformin use and its mental health benefits. However, there are a few studies that shed light on its impact on mood and cognitive function.
Metformin may have antidepressant effects in those with type 2 diabetes and depression. Studies have shown that metformin improves depressive symptoms in type 2 diabetes patients and, when combined with therapy, has an effect on reducing depression. This could be music therapy for dementia or anything else that would help the patient. The medication has also been shown to improve cognitive function and clarity. It is still not understudied how metformin affects mental health, although there are some theories that state that metformin influences neurotransmitter systems and synaptic plasticity.
However, consideration needs to be taken into account that the studies conducted were small in sample size and there needs to be more research taken into account. This medication should not be considered a treatment for depression and cognitive impairment because more research needs to be done to understand its potential as a therapeutic agent.
