Alzheimer's Disease and the Impact of Viagra

The mounting evidence suggests that Viagra may have the potential to enhance memory and cognitive abilities in individuals with Alzheimer's disease. This notion revolves around the idea that Viagra can be regarded as a therapy that enhances brain function. This characteristic is commonly found in Viagra and other PDE5 inhibitors. Substantial evidence indicates that it is widely present in the brain, as demonstrated in a rat model of high altitude.

Improving Cognitive Function

Researchers widely believe that Viagra could be a candidate for repurposing as a treatment for Alzheimer's disease. Its main medicinal ingredient, sildenafil, works by increasing blood flow to the penis, and, in the last decade, similar concentration has been shown to improve synaptic function in the brain, basically improving mental acuity. The underlying cause of Alzheimer's disease is the death of the cells, and the synapses that are responsible for taking in, processing, storing, and then passing information to the next cells remain intact. Most animal and human studies have shown that phosphodiesterase 5 inhibitors, including Viagra, improve cognition at the molecular, synaptic, behavioral, and end-organ levels, thus improving memory and learning. Such studies have also shown that it reduces the production of toxic substances in the brain that worsen Alzheimer's disease and dementia.

Enhancing Blood Flow to the brain

With Alzheimer's disease, proper blood flow to the brain is essential for maintaining proper cognitive function. Research has found that Viagra may help to improve blood flow to the brain by allowing for the dilation of blood vessels. In fact, a 2013 study published in the Journal of the American Medical Association (JAMA) Neurology showed that Viagra may even aid in the treatment of Alzheimer's disease. The research was led by J. Scott Roberts, a professor at the University of Michigan's Institute for Social Research and a member of the UM Taubman Medical Research Institute. In the study, the researchers found an association between the use of Viagra and a lesser prevalence of Alzheimer's. However, the study had been relatively small, and the results remained inconclusive.

Managing Behavioral and Psychological Symptoms of Alzheimer's

For example, caregivers and professionals need to assess the individual and their environment concerning any problematic symptoms such as aggression, agitation, suspiciousness, wandering, irritability, hallucinations, sexual disinhibition, psychosis, apathy, depression, and sleep disturbances. In addition to that, music therapy, aromatherapy, massage, doll therapy, reminiscence, and light therapy have been recognized as useful therapies. Non-pharmacological approaches are currently the therapies of choice for the management of BPSD; the psycho-social model is one of the most widely used modalities in dealing with BPSD, especially among individuals living in care facilities. Pharmacological treatment can be used as part of the overall approach to managing BPSD and may be appropriate when the severity of the behaviors is great and when other interventions have failed. Thus, managing the behavioral and psychological symptoms of Alzheimer's is not just restricted to the use of medication. Instead, it refers to therapies that are to be employed to delay the process of the disease, alleviate the suffering of the patients, decrease the caregivers' burden, and, last but not least, improve the quality of life of the individuals living with Alzheimer's.

Considerations and Limitations

Safety and Side Effects of Viagra in Alzheimer's Patients

In general, Viagra is considered to be safe if it is used correctly and by a healthy person. However, as with any drug, it can have side effects that can range from, in the best case, mild annoyance to, in the worst case, severe harm to the body. In relation to the specific case of Alzheimer's, the Alzheimer's Association states that too much use of Viagra can result in ischemic optic neuropathy, a disease that can lead to blindness, among other problems. Also, since the body of an Alzheimer's patient is in a highly fragile state, it is possible that the person will experience a heart attack during intercourse, which can be life-threatening. Even if the person survives, it can lead to a series of complications in the brain that could worsen the Alzheimer's condition.

Drug Interactions and Contraindications

It is important for anyone taking the treatment to know about potential drug interactions and contraindications that could occur between Viagra, which dilates blood vessels, and medication taken for Alzheimer's disease, many of which are vasoconstrictors. Examples include cholinesterase inhibitors like Donepezil and NMDA-receptor antagonists like Memantine. The use of Viagra may cause several side effects and contraindications such as hypotension, prolonged erections, priapism, myocardial infarction, ventricular arrhythmias and sudden hearing loss. Many of these side effects can be increased in severity if the patient with Alzheimer's Disease is taking medications that interact poorly with Viagra. The long-term use of Viagra in Alzheimer's patients can increase the risk of stroke due to the increased chance of hemorrhaging in patients who are taking both. Although it is uncommon for people who are struggling with advanced Alzheimer's Disease to also be taking Viagra, it is not unheard of, and the risk of serious, life-threatening complications comes down to the responsibility of the caregiver.
