Understanding Levetiracetam: A Promising Drug to Treat Alzheimer's Disease

Updated: Jul 18, 2023

Alzheimer's disease is a neurodegenerative disorder that affects millions of people worldwide. It is a progressive disease that gradually destroys memory and cognitive functions, leading to severe impairment of daily activities. While several drugs have been developed to treat Alzheimer's disease, none of them have been able to provide a cure or halt the progression of the disease. However, recent research has identified a promising drug called Levetiracetam that has the potential to treat Alzheimer's disease. In this article, we will take a deep dive into the research and development of Levetiracetam as a treatment for Alzheimer's disease.


What is Levetiracetam?

Levetiracetam is an antiepileptic drug that is commonly used to treat epilepsy. It works by inhibiting the abnormal activity of neurons in the brain, thereby preventing seizures. However, recent research has shown that Levetiracetam may also have potential in treating Alzheimer's disease.

Research on Levetiracetam as a Treatment for Alzheimer's Disease

In a recent study conducted by researchers at MIT, Levetiracetam was found to reverse memory impairments caused by hyperactivity and neurodegeneration in mammillary body neurons in mice. The mammillary body is a part of the hypothalamus that is one of the first brain regions to show neurodegeneration in Alzheimer's disease. The researchers identified a subset of neurons within the mammillary body that are most susceptible to neurodegeneration and hyperactivity. They found that this damage leads to memory impairments, suggesting that this region may contribute to some of the earliest symptoms of Alzheimer's disease.

The researchers found that Levetiracetam could reverse memory impairments caused by hyperactivity and neurodegeneration in mammillary body neurons in mice. The drug reduced neuronal hyperactivity, leading to significant improvements in memory tasks. Levetiracetam is currently used to treat epileptic seizures and is also in clinical trials to treat hyperexcitability in the cortex, which increases the risk of seizures in Alzheimer's patients.

How Levetiracetam Works

Levetiracetam works by binding to a specific protein called synaptic vesicle protein 2A (SV2A), which is involved in the release of neurotransmitters in the brain. By binding to SV2A, Levetiracetam reduces the release of excitatory neurotransmitters, such as glutamate, and increases the release of inhibitory neurotransmitters, such as GABA. This mechanism of action helps to reduce the abnormal activity of neurons in the brain, which is beneficial in treating both epilepsy and Alzheimer's disease.

Clinical Trials of Levetiracetam for Alzheimer's Disease

Several clinical trials are currently underway to investigate the efficacy of Levetiracetam in treating Alzheimer's disease. One such trial is being conducted by researchers at the University of California, San Francisco. The trial aims to evaluate the safety and efficacy of Levetiracetam in treating Alzheimer's disease in patients with mild cognitive impairment. The trial will involve a total of 60 patients, who will receive either Levetiracetam or a placebo for a period of six months.

Another clinical trial is being conducted by researchers at the University of Kansas Medical Center. The trial aims to investigate the effects of Levetiracetam on brain function in patients with Alzheimer's disease. The trial will involve a total of 30 patients, who will receive either Levetiracetam or a placebo for a period of six months. The researchers will use various imaging techniques to evaluate changes in brain function over the course of the trial.

Advantages of Levetiracetam as a Treatment for Alzheimer's Disease

Levetiracetam has several advantages as a potential treatment for Alzheimer's disease. Firstly, it has a favorable side effect profile and is well-tolerated by patients. Secondly, it has a well-established safety profile, having been used to treat epilepsy for over 20 years. Thirdly, it has a unique mechanism of action that targets synaptic vesicle protein 2A, which is involved in the release of neurotransmitters in the brain. This mechanism of action may be beneficial in treating both epilepsy and Alzheimer's disease.

Conclusion

Alzheimer's disease is a devastating disorder that affects millions of people worldwide. While several drugs have been developed to treat Alzheimer's disease, none of them have been able to provide a cure or halt the progression of the disease. However, recent research has identified a promising drug called Levetiracetam that has the potential to treat Alzheimer's disease. Levetiracetam works by inhibiting the abnormal activity of neurons in the brain, which is beneficial in treating both epilepsy and Alzheimer's disease. Several clinical trials are currently underway to investigate the efficacy of Levetiracetam in treating Alzheimer's disease, and the results of these trials will provide valuable insights into the potential of this drug as a treatment for Alzheimer's disease.
