How to use medications to manage Alzheimer’s and Parkinson’s

Alzheimer’s disease and Parkinson’s disease are two of the most common neurodegenerative disorders, affecting millions of people worldwide.

While both diseases are currently incurable, medications play a crucial role in managing symptoms, improving quality of life, and in some cases, slowing disease progression.

This review offers a clear overview of how medications are used in the treatment of Alzheimer’s and Parkinson’s, with a focus on making the information accessible to non-scientists.

Alzheimer’s disease primarily affects memory and cognitive functions. The medications approved for Alzheimer’s aim to improve symptoms related to cognition, such as memory loss and judgment, and to manage behavioral changes, such as depression or agitation.

The most commonly prescribed medications for Alzheimer’s are cholinesterase inhibitors (such as donepezil, rivastigmine, and galantamine).

These drugs work by increasing levels of acetylcholine, a chemical messenger involved in memory and learning, which is typically low in Alzheimer’s patients.

Another drug commonly used in Alzheimer’s treatment is memantine. Memantine works differently from cholinesterase inhibitors.

It regulates the activity of glutamate, another important brain chemical that, when produced in excessive amounts, can lead to brain cell death. Memantine is often used in the later stages of Alzheimer’s and can be combined with a cholinesterase inhibitor.

In addition to these, recent advances have introduced new types of treatments that target the underlying causes of Alzheimer’s, such as the buildup of amyloid-beta plaques in the brain—one of the hallmarks of the disease.

For example, aducanumab, approved in some regions, is designed to help reduce these plaques. However, its use is surrounded by controversy regarding its efficacy and safety.

Turning to Parkinson’s disease, this condition is characterized by tremors, stiffness, and difficulty with balance and coordination.

The cornerstone of Parkinson’s treatment is levodopa, which the brain converts into dopamine, a neurotransmitter that is deficient in Parkinson’s patients.

Since levodopa’s effectiveness can diminish over time and with continuous use, it is often combined with carbidopa, which prevents levodopa from breaking down before it reaches the brain.

Other medications used to manage Parkinson’s include dopamine agonists (such as pramipexole and ropinirole), which mimic the effects of dopamine in the brain.

There are also MAO-B inhibitors (such as selegiline and rasagiline) that help prevent the breakdown of brain dopamine by inhibiting the enzyme monoamine oxidase B.

An important aspect of managing Parkinson’s disease is adjusting the medication regimen over time as the disease progresses and symptoms evolve.

This might involve increasing dosages, combining different types of drugs, or changing medications altogether to manage side effects and maintain functionality.

For both Alzheimer’s and Parkinson’s, medication management is highly individualized. What works for one person may not work for another, and it often requires careful monitoring and adjustments by healthcare professionals.

Patients and caregivers should also be aware of the potential side effects of medications, which can include gastrointestinal upset, dizziness, and more serious effects such as heart issues or severe mood changes.

Effective treatment of Alzheimer’s and Parkinson’s involves more than just medications. Comprehensive care includes lifestyle modifications, physical and occupational therapies, and support for caregivers.

Despite the challenges these diseases present, advancements in treatment and management strategies continue to improve the ability to provide care and enhance the quality of life for those affected.

In conclusion, while there is no cure for Alzheimer’s or Parkinson’s, effective medication management can alleviate symptoms and improve quality of life.

Patients, caregivers, and healthcare providers need to work closely together to tailor treatments to individual needs, monitor progress, and adjust strategies as required.
