Parkinson’s disease (PD) is a neurodegenerative disorder that affects movement, while dementia is a term used to describe a decline in cognitive function that can impact a person’s ability to carry out daily activities. Does Parkinson’s cause Dementia? While the two conditions are distinct, there is a strong link between Parkinson’s disease and dementia.

What Causes Degeneration of Neurons in The Brain?

There are many factors that can contribute to the degeneration of neurons in the brain, and the specific causes can vary depending on the type of degenerative disease or disorder. Here are some examples of factors that can contribute to neuron degeneration:

Genetics: Inherited genetic mutations can lead to the production of abnormal proteins or other cellular changes that can cause neurons to degenerate.

Environmental factors: Exposure to toxins, such as pesticides or heavy metals, can damage neurons and contribute to neurodegenerative diseases.

Aging: As we age, our cells become less efficient at repairing damage, and this can lead to the accumulation of damaged proteins and other cellular changes that can contribute to neuron degeneration.

Inflammation: Chronic inflammation in the brain can damage neurons and contribute to the development of neurodegenerative diseases.

Trauma: Traumatic brain injuries can cause physical damage to neurons and lead to neurodegeneration.

Other medical conditions: Some medical conditions, such as diabetes, high blood pressure, and autoimmune diseases, can increase the risk of neuron degeneration.

It is often a combination of these factors, rather than a single cause, that may be the contributors to neuron degeneration in Parkinson’s Disease.

Research suggests that up to 80% of people with Parkinson’s disease will experience some cognitive decline over the course of their illness, with about 50% developing dementia at some point in their lives. This type of dementia is known as Parkinson’s disease dementia (PDD).

What is Parkinson’s Disease Dementia (PDD)

Parkinson’s disease dementia (PDD) is a type of dementia that affects some people with Parkinson’s disease (PD). The symptoms of PDD can include memory loss, difficulty with planning and problem-solving, and changes in mood and behavior. PDD typically develops several years after the onset of PD, and the severity of cognitive impairment can vary widely from person to person.

In addition to cognitive changes, people with PDD may also experience motor symptoms associated with PD, such as tremors, stiffness, and slowed movements. Behavioral and psychological symptoms, such as depression, anxiety, hallucinations, and delusions, are also common in PDD.

How Does PDD Develop?

The exact cause of PDD is not fully understood, but it is believed to be related to the degeneration of neurons in specific areas of the brain that are affected by both PD and dementia. It is also believed to be a result from the accumulation of abnormal proteins in the brain, including alpha-synuclein, which is also involved in the development of Parkinson’s disease. 

It is important to note that not everyone with Parkinson’s disease will develop PDD, and there are treatments available to help manage both conditions. People with Parkinson’s disease who are concerned about cognitive decline should speak with their healthcare provider for guidance on how to monitor and manage their symptoms.

What Are Treatment Options For PDD?

While there is no cure for Parkinson’s disease dementia (PDD), there are treatments available that can help manage the symptoms of the disease and improve quality of life for people with PDD. Here are some ways that PDD can be managed:

Medications: There are several medications that can be used to manage the symptoms of PDD, including medications to manage the motor symptoms of Parkinson’s disease, as well as medications to manage cognitive and behavioral symptoms.

Cognitive and behavioral therapy: Therapy sessions with a trained healthcare professional can help people with PDD and their caregivers learn strategies for managing cognitive and behavioral symptoms, such as memory loss, depression, and anxiety.

Exercise: Exercise has been shown to be beneficial for people with Parkinson’s disease, and it may also help improve cognitive function and mood in people with PDD.

Support groups: Joining a support group can help people with PDD and their caregivers connect with others who are facing similar challenges and provide emotional support and practical advice.

Lifestyle changes: Eating a healthy diet, getting enough sleep, and reducing stress can all help improve overall health and may help manage symptoms of PDD.

It is important for people with PDD and their caregivers to work closely with their healthcare provider to develop a personalized treatment plan that addresses their specific symptoms and needs.

Regenerative Medicine for Parkinson’s Disease Dementia

Another option that is outside of traditional medicine that patients are exploring is regenerative medicine, also known as stem cell therapy. This therapy involves the use of stem cells to repair or replace damaged or diseased tissues in the body. Stem cells are unique because they have the ability to differentiate, or transform, into different types of cells, such as muscle cells, nerve cells, or blood cells. This makes them a potentially useful tool for repairing damaged tissues or replacing lost or damaged cells in the body. 

Mesenchymal stem cells (MSCs) are being investigated for their potential use in a variety of therapeutic applications, including the treatment of musculoskeletal disorders, cardiovascular disease, and neurological disorders such as Parkinson’s disease and multiple sclerosis. Mesenchymal stem cells (MSCs) are derived from adult tissues isolated from the patient’s own tissue (autologous) or from a donor (allogeneic). 

While research continues regarding the use of MSCs for the management of neurological conditions, there has been some evidence to suggest that it may have potential as a therapeutic option. Studies have shown that MSCs can migrate to damaged areas of the brain and release neurotrophic factors, which can promote the growth and survival of neurons. 

MSCs may also have anti-inflammatory properties, which could help reduce inflammation in the brain that is associated with neurodegenerative diseases such as PDD. They have the ability to modulate the immune response and produce a variety of growth factors and other signaling molecules that can help promote tissue repair and regeneration.

If you are looking into options for yourself or a loved one, talk to your healthcare provider about which options are best for the management of your condition. When options are limited or not showing improvement, regenerative medicine may be an option worth exploring. When looking for a provider in this industry is important to have the elements of experience, transparency, and quality control.
