Parkinson’s Disease Lawsuit [2025]: Have You or a Loved One Suffered From Parkinson’s Disease After Using Paraquat Herbicide Weed Killer?

Parkinson's disease lawsuit cases settlement claims herbicide weedkiller

If you or a loved one were diagnosed with or suffered from Parkinson’s disease after using or being exposed to Paraquat weed killer herbicide, you may be entitled to recover compensation from a Parkinson’s disease lawsuit case or settlement claim.

A team of products liability injury attorneys and class action lawyers is investigating potential lawsuit cases and settlement claims of individuals who claim to have been diagnosed with or suffered from Parkinson’s disease after using or being exposed to Paraquat weed killer.

Parkinson’s disease (PD) is a long-term neurodegenerative brain disorder affecting the ability of a person to control movement that develops when dopamine-producing nerve cells (dopaminergic neurons) in the substantia nigra area of the basal ganglia (a part of the brain that controls movement) become impaired and/or die.

According to the Parkinson’s Foundation, nearly a million people in the U.S. are living with Parkinson’s disease, with approximately 60,000 new Parkinson’s cases being diagnosed each year. Parkinson’s disease is one of the leading causes of death in the U.S., with approximately 39,500 people expected to die from Parkinson’s complications each year.

Unfortunately, individuals who were exposed to the herbicide Paraquat may be at an increased risk of developing Parkinson’s disease.

Parkinson’s Disease Lawsuit: Overview


Parkinson’s Disease Lawsuit & Settlement Cases

Parkinson’s disease lawsuit and settlement cases potentially being investigated include claims of individuals who, after using or being exposed to Paraquat herbicide, suffered from Parkinson’s disease:

  • Parkinson’s disease
  • Parksinonism
  • Primary parkinsonism
  • Idiopathic parkinsonism
  • Paralysis agitans
  • Synucleinopathy
  • Neurodegenerative disease
  • Parkinsonian syndrome

If you or someone you love were diagnosed with Parkinson’s disease and believe that it may be due to exposure to Paraquat herbicide, you may be eligible to recover monetary compensation from a Paraquat Parkinson’s disease lawsuit or settlement case.

Parkinson’s Paraquat Exposure Injury Claims

According to John Hopkins Medicine, exposure to environmental toxins such as chemicals in pesticides and herbicides (including paraquat) may play a role in the development of Parkinson’s disease.

Indeed, thousands of Parkinson’s disease lawsuits have been filed against Paraquat manufacturers, sellers and/or distributors on behalf of individuals who claim to have developed Parkinson’s disease as a result of their exposure to Paraquat herbicides. According to the Paraquat Parkinsons lawsuits, numerous scientific studies have found a link between Paraquat exposure and Parkinson’s disease.

Parkinson’s Signs & Symptoms

Parkinson’s disease signs and symptoms can potentially include:

  • Tremor or trembling in hands
  • Tremor or trembling in arms
  • Tremor or trembling in legs
  • Tremor or trembling in jaw
  • Tremor or trembling in head
  • Tremor or trembling in limbs
  • Stiffness of limbs and trunk
  • Slowness of movement (bradykinesia)
  • Impaired balance and coordination
  • Loss of muscle control
  • Parkinsonian gait
  • Tendency to lean forward when walking
  • Small quick steps when walking
  • Reduced swinging of arms while walking
  • Slowness of movement
  • Stooping or hunching over
  • Falling down
  • Difficulty swallowing
  • Difficulty chewing
  • Difficulty speaking
  • Autonomic dysfunction (dysautonomia)
  • Urinary problems
  • Constipation
  • Small handwriting
  • Skin problems
  • Loss of smell
  • Sleep issues
  • Soft or low voice
  • Dizziness or fainting
  • Depression and anxiety
  • Parkinson’s disease dementia
  • Others Parkinson’s symptoms

Symptoms of Parkinson’s disease usually start gradually and then progressively get worse over time. A doctor or neurologist typically will diagnose Parkinson’s based on medical history, family history, physical examination, neurological exam, specific single-photon emission computerized tomography scan (SPECT scan), dopamine transporter scan (DaTscan) and a review of signs and symptoms, among others.

Parkinson’s Treatment

There is currently no cure for Parkinson’s disease. And there are also no known medical treatments to slow or stop the progression of Parkinson’s disease. However, there are treatments that are capable of temporarily and partially relieving the motor symptoms of Parkinson’s disease.

Parkinson’s disease treatment to relieve symptoms can include medications to increase or promote dopamine levels (such as carbidopa-levodopa or L-DOPA), medications to mimic dopamine effects in the brain (such as dopamine agonists like pramipexole or Mirapex, ropinirole or Requip, rotigotine or Neupro, and apomorphine, etc.), medications to help prevent the breakdown of dopamine by inhibiting the brain enzyme monoamine oxidase B (such as selegiline or Zelapar), rasagiline or Azilect and safinamide or Xadago), medications to control tremurs (such as anticholinergics like benztropine or cogentin and trihexyphenidyl), medications to prolong the effect of levodopa therapy (such as Catechol O-methyltransferase COMT inhibitors like entacapone or Comtan and opicapone or Ongentys) and surgery (such as lesion surgery to burn tissue in the brain that control movement, deep brain stimulation or DBS and neural grafting or tissue transplants), among others.

If you or someone you love suffered from Parkinson’s disease after using or being exposed to Paraquat weedkiller herbicide, you may be entitled to compensation from a Paraquat lawsuit or settlement. Contact an injury lawyer to request a free case review.
