Parkinson’s Disease and VA Disability Compensation

Parkinson’s Disease (PD) is a disease of the central nervous system, characterized by the death of dopamine-producing cells in the brain.  With less dopamine, a person has less ability to control their movements, body, and emotions.

Symptoms of Parkinson’s Disease

Symptoms of Parkinson’s Disease are generally classified as motor symptoms and non-motor symptoms.  Motor symptoms can include:

  • Rigidity
  • Tremors
  • Delayed movement
  • Poor balance

Non-motor symptoms include:

  • Sleep disturbances
  • Urinary dysfunction
  • Constipation
  • Swallowing problems
  • Mood disorders
  • Cognitive deficits

VA Disability Ratings for Parkinson’s Disease

VA rates Parkinson’s Disease under 38 CFR § 4.124a – Schedule of Ratings, Neurological Conditions and Convulsive Disorders, Diagnostic Code (DC) 8004.  This diagnostic code assigns an automatic minimum 30 percent rating for the condition, but it does not take into account the symptoms associated with it.  Therefore, VA should continue rating as follows, after beginning with the minimum 30 percent rating:

  • Evaluate each of the veteran’s symptoms/residuals associated with Parkinson’s Disease
  • Calculate the combined disability rating for those symptoms
  • Assign the higher evaluation (i.e. the minimum 30 percent rating for the disease itself or the combined rating of the symptoms)

Examples of symptoms/residuals of Parkinson’s Disease that VA can evaluate when assigning a disability rating include the following:

  • Difficulty swallowing (dysphagia) – DC 7203
  • Speech problems (dysarthria) – DC 8210
  • Bladder incontinence (neurogenic bladder) – DC 7542

Parkinson’s Disease and Agent Orange Exposure

Agent Orange is an herbicide agent that was used by the United States during the Vietnam War.  More specifically, Agent Orange is a 50/50/ mixture of two kinds of herbicide agents: 2, 4-D and 2, 5-T.  Additionally, Agent Orange contains the most toxic dioxin called TCDD.  The United States used Agent Orange during the Vietnam War to destroy enemy crops.  As a result, Vietnam veterans have developed a number of symptoms that have been traced to Agent Orange exposure, including Parkinson’s Disease.

In July 2009, the Health and Medicine Division (formally known as the Institute of Medicine) concluded in its report “Veterans and Agent Orange: Update 2008,” that there is suggestive but limited evidence that exposure to Agent Orange and other herbicides is associated with an increased chance of developing Parkinson’s Disease.  As a result, VA added Parkinson’s Disease to its list of presumptive conditions associated with Agent Orange exposure.

Presumptive Exposure to Agent Orange

Presumption of service connection, as outlined by the Agent Orange Act of 1991, requires VA to assume that veterans who served during certain time periods and locations were exposed to Agent Orange.  In relation to Parkinson’s Disease, veterans who served in the following locations and later developed Parkinson’s Disease do not have to prove that their condition is related to service:

  • Veterans with “boots on the ground,” those serving on inland waterways in Vietnam, and “blue water” Navy veterans between January 9, 1962 and May 7, 1975;
  • Veterans who flew or worked in C-123 aircraft during the Vietnam War era; and
  • Veterans who served along the Korean Demilitarized Zone (DMZ) between September 1, 1967 and August 31, 1971

Other Presumptive Conditions

VA also assumes service connection for the following conditions, in addition to Parkinson’s Disease:

  • AL Amyloidosis
  • Bladder Cancer
  • Chronic B-Cell Leukemia
  • Chloracne (if it presents within one year of exposure to a degree of 10 percent disabling)
  • Diabetes Mellitus Type 2
  • Hodgkin’s Disease
  • Hypothyroidism
  • Ischemic Heart Disease (including Coronary Artery Disease, stable and unstable angina, myocardial infarction, and sudden cardiac death)
  • Multiple Myeloma
  • Non-Hodgkin’s Lymphoma
  • Peripheral Neuropathy, Early Onset (if it presents within one year of exposure to a degree of 10 percent disabling)
  • Porphyria Cutanea Tarda (if it presents within one year of exposure to a degree of 10 percent disabling)
  • Prostate Cancer
  • Respiratory Cancers, including Lung Cancer
  • Soft Tissue Sarcomas (other than osteosarcoma, chondrosarcoma, Kaposi’s sarcoma, and mesothelioma)

Parkinson’s-like Symptoms

The 2021 NDAA, National Defense Authorization Act, passed by Congress determined that there is a link between Parkinson’s-like symptoms are Agent Orange exposure.

Parkinson’s-like symptoms refers to a condition where the symptoms may resemble Parkinson’s Disease, but have not been formally diagnosed as such.  The symptoms may include tremors, slowed movement, impaired speech, and muscle stiffness.  The addition of Parkinson’s-like symptoms to VA’s presumptive condition list will make it easier for veterans with these symptoms to secure disability benefits.

Parkinson’s Disease and Traumatic Brain Injury (TBI)

Traumatic brain injury (TBI) occurs when brain function is disrupted by a traumatic event such as an IED blast, a gunshot wound, a car accident, etc.  Rates of TBI among service members have increased substantially since the Iraq and Afghanistan wars.  VA diagnoses a veteran’s TBI as mild, moderate, or severe based on the severity of his or her symptoms.  Importantly, if Parkinson’s Disease develops at any point following a moderate or severe TBI, the veteran will be presumptively service-connected for it.

Secondary Service Connection for Disabilities Caused by Parkinson’s Disease

Parkinson’s Disease, while a neurological movement disorder, may affect other systems of the body which can lead to additional disabilities.  In the instance of Parkinson’s Disease, a secondary service-connected disability would be a disability that was caused by the Parkinson’s Disease, once it has been deemed service-connected.

Below are some conditions which may be considered secondary to Parkinson’s Disease:

  • Hypertension
  • Irregular Heartbeat
  • Ischemic Heart Disease
  • Heart Failure
  • Stroke
  • Osteoarthritis
  • Osteoporosis
  • Injuries sustained from falling
  • Anxiety
  • Depression
  • Gastrointestinal Complications
  • Sleep Conditions, such as Sleep Attacks and Obstructive Sleep Apnea

Camp Lejeune Contaminated Water Exposure and Parkinson’s Disease

VA has established a list of presumptive conditions, including Parkinson’s Disease, for service members that served at Camp Lejeune for at least 30 cumulative days from August 1, 1953 through December 31, 1987.  Therefore, Camp Lejeune veterans do not need to prove that their Parkinson’s Disease is connected to their military service.

TDIU and Special Monthly Compensation (SMC) for Parkinson’s Disease

Due to the fact that Parkinson’s Disease is such a disabling condition that often affects daily functioning, veterans can look to see if they qualify for Special Monthly Compensation (SMC) – a monthly benefit for veterans who have service-connected conditions that result in severe impairment, including the loss or loss of use of extremities, blindness, the need of regular aid and attendance, etc.

Furthermore, total disability based on individual unemployability (TDIU) may be an option if a veteran’s Parkinson’s Disease precludes him or her from securing and following substantially gainful employment.  Here, veterans will be paid at the 100 percent level regardless of their combined disability ratings.
