One of the most common symptoms of Parkinson’s disease is tremor, which involves a persistent twitching or shaking of one or more limbs. These tremors are known as rest tremors because they do not occur when the person is actively using the affected body part. Tremors usually appear on one side of the body and gradually worsen over time. Patients with tremors often notice subtle changes in their walking pattern, which may signal an underlying problem.

Essential tremor is an involuntary rhythmic tremor that can occur in the hands, arms, or head. It is often inherited. This disorder affects the globus pallidus interna (GPi), which regulates muscle tone in the brain. It is also linked to the thalamus, which relays sensory messages from the body to the brain. It can also affect the ability to write small letters or words, a condition called micrographia.

In some cases, medicines for Parkinson’s disease can help ease symptoms. Some of these medicines replace the brain chemical dopamine. Surgical procedures may be necessary if the medications fail to improve symptoms. Another option for treating Parkinson’s disease is deep brain stimulation. This procedure involves implanting electrodes into the brain. These electrodes are connected to a small electrical device in the chest. Deep brain stimulation can reduce the severity of the symptoms, and can even reduce the need for certain medicines.

While there are no known causes of Parkinson disease, scientists believe that genetics and environment play a role in its development. Environmental factors that can contribute to the disease include rural living, agricultural pesticides, and exposure to well water. These factors are not the only risk factors, however. Other risk factors include advancing age.

Diagnosing Parkinson disease requires a thorough neurological examination and medical history. Your doctor may suggest imaging tests, such as a dopamine transporter (DAT) scan, to rule out other conditions. Often, a physician will use a combination of these tests to determine the cause of the symptoms. Some doctors may also use a brain scan to confirm the diagnosis. Your doctor will need to monitor your symptoms for a while before making a definitive diagnosis.

Parkinson disease is a progressive disease, which means that the symptoms will gradually worsen over time. Symptoms may be mild and subtle in the early stages of the disease, but will eventually lead to more serious conditions such as tremors, stiffness, and a loss of ability to speak or write.

While there is no cure for Parkinson’s disease, medication can help to control the symptoms. The most common treatment is levodopa, which is a chemical used by nerve cells in the brain to make dopamine, which in turn controls movement. It is often combined with other medications to provide the best results.
