Understanding Parkinson’s Disease: Symptoms, Causes, and Treatment Options

by | Feb 10, 2024 | Diseases

Tapping fingers or shaking a leg while waiting are common habits for many, yet for some, these movements aren’t a choice but symptoms of Parkinson’s disease (PD), a movement disorder affecting 10 million people globally. According to the Parkinson’s Foundation, PD is a progressive disorder that primarily damages dopamine-producing neurons in the brain’s substantia nigra, leading to a range of neurological symptoms.

PD’s onset is subtle, often beginning with a slight tremor in one hand, stiffness, or a slowdown in movement, as highlighted by the Mayo Clinic. Over time, symptoms like a lack of facial expression and slurred or soft speech may emerge, worsening as the disease progresses.

The National Institute of Neurological Disorders and Stroke outlines four primary symptoms of PD, noting that experiences vary among individuals:

  • Tremor: Commonly starting in a limb, it may show as a “pill-rolling” motion between the thumb and forefinger, especially noticeable when the hand is at rest.
  • Rigidity: Muscle stiffness and resistance to movement can lead to discomfort and limited mobility, observable in the jerky, restricted movements of the arms when someone else attempts to move them.
  • Bradykinesia: A noticeable slowing in spontaneous movement, making routine tasks more challenging and leading to decreased facial expressions.
  • Postural instability: This symptom, affecting balance and posture, raises the risk of falls and may change a person’s walking pattern to a shuffle.

The exact cause of PD remains a mystery, though it’s believed to involve both genetic and environmental factors. While there’s no cure, treatments are available to manage symptoms, although none can halt the disease’s progression. The Mayo Clinic notes that PD brains often contain Lewy bodies, abnormal accumulations of the protein alpha-synuclein, which are under investigation for their role in the disease.

Treatment often involves dopaminergic medications to supplement the brain’s dwindling dopamine supply, offering symptom relief. Ongoing research aims to discover PD biomarkers for earlier diagnosis and personalized treatment strategies.

For those experiencing PD-like symptoms, consulting a healthcare professional is crucial. A neurologist can offer a comprehensive evaluation and discuss treatment options. With appropriate care, individuals with PD can maintain a quality of life through the years following their diagnosis.
