Key Highlights

• According to estimates, in 2023, there were approximately 2.71 million diagnosed prevalent cases of Parkinson’s disease in the 7MM. Of these, the United States accounted for 45% of the cases, while Japan and Germany represented 9% and 18% of the cases, respectively.
• In 2023, EU4 and the UK recorded nearly 1.24 million diagnosed prevalent cases of Parkinson's disease. These cases are projected to grow significantly at a compound annual growth rate (CAGR) throughout the study period from 2020 to 2034.

Parkinson’s Disease Understanding

Parkinson’s Disease Overview

According to the Parkinson’s Foundation, Parkinson’s disease is a neurodegenerative disorder that affects predominately dopamine-producing (dopaminergic) neurons in a specific area of the brain called the substantia nigra. Because Parkinson’s disease develops over time, various stages help identify how symptoms have progressed and what should be expected next. Generally, there are five stages of Parkinson’s disease: Stage I, Stage II, Stage III, Stage IV, and Stage V.

According to the National Health Service (NHS), there are many different symptoms associated with Parkinson’s disease. However, the order in which these develop and their severity differ for individuals. It is unlikely that a person with Parkinson's disease would experience all or most of these. The main symptoms referred to by doctors as parkinsonism include tremors, slowness of movement (bradykinesia), and muscle stiffness (rigidity), which are classified as motor symptoms while non-motor symptoms include cognitive changes, autonomic dysfunctioning, mood and sleep disorders, and others.

While the exact cause of Parkinson’s disease is not known, a combination of genetic and environmental factors is believed to contribute to its development. Other risk factors include age, gender, head trauma, and use of certain medications.

Parkinson’s Disease Diagnosis

Diagnosing Parkinson's disease can be challenging, as there is no definitive test for the condition. Instead, the diagnosis is typically based on a combination of medical history, symptoms, physical and neurological examinations, and sometimes additional tests. MRI may be used only to exclude other causes. DaTscan, an imaging test, can assist in confirming the diagnosis by assessing dopamine levels in the brain. Additionally, advancements in neuroimaging studies, including transcranial Doppler ultrasonography, PET, single-photon emission computed tomography (SPECT), morphometric MRI studies, tractography, functional MRI, and perfusion imaging, are being used to differentiate idiopathic Parkinson's disease from other parkinsonian disorders. Radionuclide imaging modalities like PET and SPECT, using a dopamine transporter ligand, have become the best approach to assess dopamine metabolism and deficiency.

Diagnosing Parkinson's disease presents significant challenges due to its gradual onset and symptom overlap with other neurodegenerative disorders. Early symptoms are often subtle and vary widely among individuals, complicating detection. Moreover, there is no definitive biomarker or diagnostic test, relying instead on clinical evaluations and symptom history, which can lead to misdiagnoses and delays in treatment initiation and care planning.

Parkinson’s Disease Epidemiology

For the purpose of designing the patient-based model for Parkinson’s Disease, the report provides historical as well as forecasted epidemiology segmented by Total Diagnosed Prevalent Cases of Parkinson’s Disease, Gender-specific Diagnosed Prevalent Cases of Parkinson’s Disease, Age-specific Diagnosed Prevalent Cases of Parkinson’s Disease, Stage-specific Diagnosed Prevalent Cases of Parkinson’s Disease, Diagnosed Prevalent Cases of Psychosis due to Parkinson's Disease, and Diagnosed Prevalent Cases of MCI due to Parkinson's Disease in the 7MM covering the United States, EU4 countries (Germany, France, Italy, and Spain) and the United Kingdom, and Japan, from 2020 to 2034.

The analyst estimate that in 2023, the United States accounted for the highest cases of diagnosed Parkinson’s disease across the 7MM, totaling 1.21 million cases. The analyst forecasts a rise in this figure by 2034, reflecting the growing burden of the disease. This trend underscores the increasing healthcare challenge posed by Parkinson’s in the US during the forecast period.

In the assessment done, the estimated total diagnosed prevalent cases of Parkinson’s disease in Japan were nearly 257 thousand in 2023.

Among the EU4 and the UK, Germany accounted for the highest diagnosed prevalent cases of Parkinson’s disease with nearly 495 thousand cases in 2023 followed by France accounting for approximately 277 thousand cases. On the other hand, Spain accounted for the least with nearly 149 thousand cases.

In 2023, Japan accounted for approximately 135 thousand cases in males and 123 thousand cases in females, based on gender-specific diagnosed prevalent cases of Parkinson’s disease. These cases are expected to increase during the forecast period.

In the US, nearly 19 thousand cases were diagnosed with Parkinson’s disease in the age group =49 years, 215 thousand cases in 50-64 years, 449 thousand cases in 65-74 years, and 527 thousand cases in =75 years in 2023.

Among the stage-specific diagnosed prevalent cases of Parkinson’s disease in Japan, there were approximately 9 thousand cases for Stage I, 40 thousand cases for Stage II, 107 thousand cases for Stage III, 70 thousand cases for Stage IV, and 31 thousand cases for Stage V in 2023.

In Japan, there were approximately 73 thousand cases of psychosis associated with Parkinson’s disease in 2023.

In the assessment done, the estimated Diagnosed Prevalent Cases of MCI due to Parkinson's Disease in the US were nearly 508 thousand in 2023.
