Parkinson's Disease Know The Important Symptoms & Treatments
August 31, 2020
Parkinson’s disease – you may have heard of it because Neil Diamond and Ozzy Osbourne were recently diagnosed with it. Or perhaps you know Michael J. Fox is a strong advocate and funds research through his foundation. Neurologist Jonathan Spivack, MD, discusses this disease, while physiatrist Stephanie Jones, DO, explains how physical therapy can help as a supplemental treatment.
According to the Parkinson’s Foundation about ten million people worldwide currently have this disease.
What is Parkinson’s Disease?
“Parkinson’s disease is a neurodegenerative disease that progresses slowly and definitely, though at variable rates,” explains Dr. Spivack. “Symptoms go beyond the classic motor changes. It results from a loss of specific dopamine-producing brain cells. Specifically, this loss is likely due to a mix of genetic and environmental factors,” he adds.
Dopamine allows communication between particular nerve cells responsible for movement. If you have Parkinson’s dopamine levels gradually drop, causing a loss of motor skills. Generally, most patients with the disease are over age 65.
Early Signs and Symptoms
Diagnosing Parkinson’s can be difficult as some of the symptoms happen during the natural aging process. The Parkinson’s Foundation identifies the following 10 early signs of PD:
- Tremors or shaking of your hand, fingers or chin
- Small handwriting
- Loss of smell
- Sudden movements during sleep
- Stiffness when walking or moving
- Softer or lower voice volume
- Mad facial expression
- Feeling dizzy or faint
- Hunching or stooping posture
A single sign may not point to the disease, but if you (or a loved one) has multiple signs, talk to your healthcare provider.
Diagnosing Parkinson’s Disease
“It is a clinical diagnosis, based on symptoms that evolve over the course of the disease,” says Dr. Spivack. “There is no diagnostic test that can establish the disease.”
There are three cardinal symptoms, though only two need be present
- Rigidity: stiffness of muscles
- Bradykinesis: slowness of movements
Not all symptoms are present at the outset, but develop over the course of the disease.
Diagnosing Parkinson’s disease can be difficult as some of the symptoms happen during the natural aging process. tests are not done for a diagnosis, but to rule out other illnesses than can mimic it.
Cause of Parkinson’s
Currently the cause of Parkinson’s is unknown, although scientists are researching three main factors.
- The environment – Several studies also suggest extended exposure to chemicals and environmental factors may play a part in developing Parkinson’s disease.
- Aging – Most people develop Parkinson’s at the age of 50 or older, although a small percentage develop Young Onset Parkinson’s disease.
Treatment for Parkinson’s
“Treating Parkinson’s involves both medication and non-medication based modalities, along with surgery in specific cases,” observes Dr. Spivack. “The mainstay is medication based; all patients with the disease require their use. It is in advanced cases where surgery can be considered.”
“Treatments are symptom-based, variable in efficacy, and there is still controversy about when to start. Symptoms are controlled to a degree, the benefit(s) still lost over time, but life span is prolonged. With this comes significant functional disabilities at home, work, etc., all of which need to be addressed,” adds Dr. Spivack.
A neurologist is essential in the care of a Parkinson’s patient. “Because the disease has so many different symptoms, the treatments are multifaceted, so must be adjusted patient by patient,” says Dr. Spivack. “With all of these complexities, non-pharmacologic interventions like physical, occupational, speech, and nutritional therapies are critical to maintaining quality of life.”
Physical Therapy for Parkinson’s
“In addition to medication management of Parkinson’s, physical therapy is an important supplemental treatment of symptoms,” says Dr. Jones. “Continuing to participate in formal physical therapy sessions and maintaining a baseline level of physical activity can preserve, and even improve, a patient’s function, which includes their capability to walk and their balance.”
“Physical therapy can also help reduce negative secondary complications such as decreased range of motion of the joints and hardening (or shortening) of tissue,” adds Dr. Jones. “Lastly, it is important to follow a home exercise program, as prescribed by the physical therapist, to continue rehabilitation daily at home.”
