<h2>What is Parkinson&#8217;s disease?</h2>
What is Parkinson’s disease? It is best described as a long-term degenerative disorder of the central nervous system. It primarily impacts the motor system, leading to difficulties with movement and coordination. It is important to distinguish it from other neurological conditions like Alzheimer’s disease or general memory loss, though cognitive changes can occur in later stages.
&nbsp;
It develops when neurons (nerve cells) in a specific area of the brain, the substantia nigra, begin to break down or die. These neurons are responsible for producing dopamine, a chemical messenger that helps coordinate smooth, controlled movements. As dopamine levels decline, the brain loses its ability to properly regulate movement, leading to the hallmark motor symptoms that define Parkinson&#8217;s disease. Over time, the condition can also affect non-motor functions, including mood, cognition, sleep, and autonomic processes like blood pressure.
&nbsp;
In medical records and healthcare systems worldwide, the code for Parkinson&#8217;s disease from ICD-10 is G20. This standardized classification is used by physicians for diagnosis, treatment planning, and insurance documentation, making it especially relevant for expats who manage their healthcare across different countries and medical systems.

The symptoms of Parkinson&#8217;s disease typically develop gradually and often begin on one side of the body before progressing. Recognizing Parkinson&#8217;s disease symptoms early is key to timely intervention.
<ul>
<li style="font-weight: 400">Tremor (shaking) 
Tremors often begin in a limb, such as the hand or fingers. You may also notice facial tremors associated with Parkinson’s disease, or a rhythmic shaking of the jaw or lips.</li>
<li style="font-weight: 400">Bradykinesia (slowness of movement) 
Over time, Parkinson&#8217;s disease reduces the ability to initiate and complete movements, making everyday tasks like buttoning a shirt or rising from a chair more difficult.</li>
<li style="font-weight: 400">Muscle rigidity 
Stiffness in the limbs or trunk, which can limit range of motion and cause discomfort.</li>
<li style="font-weight: 400">Postural instability 
Impaired balance and coordination, increasing the risk of falls, particularly in the later stages of Parkinson&#8217;s disease.</li>
</ul>
&nbsp;
<h2>What causes Parkinson&#8217;s disease?</h2>
What causes Parkinson&#8217;s disease remains a central question in neurology research. While a definitive single cause has not been identified, scientists believe that Parkinson&#8217;s disease results from a combination of genetic and environmental factors.
<ul>
<li>Genetic Factors</li>
</ul>
Parkinson&#8217;s disease causes include specific genetic mutations. Variants in genes such as LRRK2, PINK1, PRKN, and SNCA have been linked to familial forms of the disease. However, inherited Parkinson&#8217;s disease accounts for only a small percentage of cases. Most are considered &#8220;idiopathic,&#8221; meaning they arise without a clear hereditary cause.
<ul>
<li>Environmental Factors</li>
</ul>
Environmental exposures are another recognized contributor to Parkinson&#8217;s disease cause. Research suggests prolonged exposure to certain pesticides, herbicides (such as paraquat and rotenone), and industrial chemicals may increase risk. Rural living and agricultural work have historically been associated with slightly higher rates of Parkinson&#8217;s disease, possibly due to pesticide exposure and well-water use.
<ul>
<li>The Role of Alpha-Synuclein</li>
</ul>
A protein called alpha-synuclein plays a central role in Parkinson&#8217;s disease. In healthy brains, this protein functions normally. In those with Parkinson&#8217;s disease, it misfolds and clumps together into abnormal deposits called Lewy bodies, which disrupt neuron function and accelerate cell death.

Certain factors are known to increase the likelihood of developing Parkinson&#8217;s disease. Understanding these risks can motivate proactive health monitoring.
<ul>
<li style="font-weight: 400">Age: The most significant risk factor for Parkinson&#8217;s disease is advancing age. The condition most commonly develops in people over 60, though early-onset Parkinson&#8217;s disease can occur before age 50.</li>
<li style="font-weight: 400">Sex: Men are approximately 1.5 times more likely to develop Parkinson&#8217;s disease than women, though the reasons for this are not fully understood.</li>
<li style="font-weight: 400">Family history: Having a first-degree relative with Parkinson&#8217;s disease moderately increases risk, particularly if genetic mutations are involved.</li>
<li style="font-weight: 400">Toxin exposure: As noted under Parkinson&#8217;s disease causes, ongoing or significant exposure to pesticides and industrial chemicals is associated with increased risk.</li>
<li style="font-weight: 400">Head trauma: Repeated head injuries or traumatic brain injury may increase susceptibility to Parkinson&#8217;s disease later in life.</li>
<li style="font-weight: 400">Reduced physical activity: Some research suggests sedentary lifestyles may be associated with higher risk, while regular aerobic exercise may offer a modest protective effect.</li>
</ul>
&nbsp;
<h2>Complications of parkinson&#8217;s disease</h2>
As Parkinson&#8217;s disease progresses through its stages, complications can arise that affect overall health and quality of life. Being aware of these helps patients and caregivers plan appropriate support.
<ul>
<li style="font-weight: 400">Falls and fractures: Balance problems in the later stages of Parkinson&#8217;s disease significantly increase fall risk, which can lead to serious injuries, particularly hip fractures.</li>
<li style="font-weight: 400">Dysphagia (difficulty swallowing): As muscles weaken, swallowing becomes difficult, raising the risk of aspiration pneumonia.</li>
<li style="font-weight: 400">Dementia and cognitive decline: In advanced Parkinson&#8217;s disease, cognitive impairment including difficulties with thinking, memory, and reasoning can develop. This may overlap with other dementias such as Alzheimer&#8217;s disease.</li>
<li style="font-weight: 400">Depression and anxiety: Emotional health complications are common across all stages of Parkinson&#8217;s disease and require dedicated mental health support.</li>
<li style="font-weight: 400">Sleep disorders: Disrupted sleep patterns, vivid dreams, and excessive daytime sleepiness are frequently reported by those with Parkinson&#8217;s disease.</li>
<li style="font-weight: 400">Urinary problems and constipation: Autonomic dysfunction caused by Parkinson&#8217;s disease can affect bladder and bowel function.</li>
<li style="font-weight: 400">Cardiovascular complications: Orthostatic hypotension (a sudden drop in blood pressure upon standing) is common and, in some patients, may interact with pre-existing <a href="https://www.phyathai.com/en/article/heart-disease-2">heart disease</a> or <a href="https://www.phyathai.com/en/article/arrhythmia-2">arrhythmia.</a></li>
