Parkinson disease living patient overview

Overview

Parkinson's disease is a condition that affects the brain over time. It causes problems with movement, such as shaking, stiffness, and trouble walking or balancing. It happens because certain brain cells that produce a chemical called dopamine slowly stop working.

Parkinson's disease is one of the most common neurologic conditions in older adults. About 1 in 500 people will develop it at some point in their life.

Parkinson's mostly affects people over the age of 60, but about 5 to 10 out of every 100 people with the condition start having symptoms before age 50. It is slightly more common in men than in women.

Symptoms

Common symptoms

• Tremor — shaking in a hand, arm, leg, or chin, especially when at rest
• Bradykinesia — slowness of movement, making simple tasks take longer
• Rigidity — stiffness in the arms, legs, or trunk
• Postural instability — problems with balance and coordination, increasing fall risk

Symptoms in children

• Parkinson's is extremely rare in children. Children with similar symptoms (tremors or muscle stiffness) usually have other conditions, like dystonia or juvenile parkinsonism, which need a specialist's evaluation.

Symptoms in older adults

• The same common symptoms also occur in older adults, but they may also experience more problems with constipation, sleep disturbances (such as acting out dreams), difficulty swallowing, and changes in thinking or memory.

Causes

Main causes

• The exact cause of Parkinson's is not known. It happens when a group of brain cells that make dopamine start to die, affecting how the brain controls movement.
• In rare cases, specific genetic changes can cause the condition. But for most people, Parkinson's likely results from a combination of genes and environmental triggers.

Risk factors

• Age — risk increases as you get older
• Family history — having a close relative with Parkinson's slightly raises your risk
• Exposure to certain toxins — such as pesticides or herbicides, though the link is not fully proven
• Head injuries — repeated head trauma may increase risk in some people

When to see a doctor

See a doctor urgently if:

• If you have a sudden worsening of symptoms, such as severe tremors or inability to move
• If you fall and hit your head, or experience new confusion
• If you have trouble swallowing or a high fever

Book a routine appointment if:

• If you notice a tremor in your hand, arm, or leg that does not go away
• If your movements feel stiff, slow, or you have trouble starting to walk
• If family or friends say your balance seems unsteady or you seem to be shuffling

Diagnosis

There is no single test for Parkinson's disease. A neurologist (a doctor who specialises in brain and nerve conditions) will take a detailed history, ask about your symptoms, and perform a physical exam to see how you move, walk, and balance. The diagnosis is based on your symptoms and how they respond to initial treatments.

Tests that may be done

• Medical history and neurological exam
• Blood tests to rule out other conditions
• Dopamine transporter scan (DaTscan) — a special imaging test that can help support the diagnosis
• Sometimes an MRI of the brain to check for other causes

What to expect at your appointment

The doctor will watch you do simple tasks like tapping your fingers, standing up from a chair, and walking. You may be asked to write a sentence or draw a spiral. The diagnosis can take time, and sometimes you may need follow-up visits to see how your symptoms change. If Parkinson's is suspected, your doctor may prescribe a trial of medication to see if it improves your symptoms.

Treatment

Treatment for Parkinson's focuses on managing symptoms and improving your daily life. It is tailored to each person and may include medications, therapies, and lifestyle changes. There is no cure, but many people can live well with the condition for many years.

Self-care at home

• Exercise regularly — activities like walking, swimming, tai chi, or dancing can help with movement and balance
• Eat a healthy, balanced diet with plenty of fibre to prevent constipation
• Get enough sleep and practice good sleep habits
• Stay socially connected with friends, family, or support groups

Medical treatments

Medicines for Parkinson's work by increasing dopamine levels in the brain or mimicking its effects. They are usually very effective in the early years. As the condition progresses, adjustments may be needed. Physical therapy, occupational therapy, and speech therapy can also help with movement, daily tasks, and communication. In more advanced stages, other therapies such as deep brain stimulation may be considered.

When is surgery considered?

For some people with advanced Parkinson's whose symptoms are not well controlled with medicine, a surgical option called deep brain stimulation (DBS) may be an option. DBS involves placing tiny electrodes in specific parts of the brain and connecting them to a device similar to a pacemaker that sends electrical signals. This can reduce tremors, stiffness, and slowness. It does not cure the disease but can improve quality of life. Your healthcare team will explain if this might be right for you.

Living with this condition

Living with Parkinson's means adapting to changes in movement, but many people continue to work, enjoy hobbies, and spend time with loved ones. It helps to keep a daily routine, allow extra time for tasks, and use tools like grab bars, walking aids, or utensils with larger handles. Planning ahead can make life easier.

Lifestyle tips

• Stay active — exercise is one of the best ways to protect your brain and keep your body moving
• Protect your sleep — a regular bedtime routine and avoiding caffeine late in the day can help
• Manage stress — relaxation techniques like deep breathing or meditation may help
• Drive safely — Parkinson's can affect reaction time and vision; check with your doctor about driving

Diet and exercise

A diet rich in fruits, vegetables, whole grains, and lean protein supports overall health. Eating enough fibre helps prevent constipation, which is common in Parkinson's. Exercise is very important — aim for at least 30 minutes of moderate activity most days. Balance exercises like tai chi or yoga can reduce fall risk. Your doctor or physiotherapist can help create a safe plan.

Mental health and emotional wellbeing

Parkinson's can affect mood and thinking. Many people experience depression, anxiety, or apathy. These feelings are a part of the condition, not a sign of weakness. Talk to your doctor if you feel down or worried — treatments like counselling, support groups, and sometimes medicines can help. It is also normal to have mild memory or concentration problems.

Prevention

There is no proven way to prevent Parkinson's disease. Some research suggests that regular exercise, a healthy diet (like the Mediterranean diet), and avoiding exposure to pesticides might lower your risk, but more studies are needed. The best approach is to live a healthy lifestyle overall.

Complications

If left untreated

• Worsening symptoms — tremors, stiffness, and slowness can become more disabling
• Falls and fractures due to poor balance
• Difficulty swallowing, which can lead to choking or pneumonia
• Constipation and other digestive problems
• Depression, anxiety, and cognitive changes (including dementia in some cases)

Long-term outlook

Parkinson's is a long-term condition that changes over time, but many people live full and active lives for years after diagnosis. With good medical care, therapies, and support, symptoms can be managed well. Research is ongoing, and new treatments continue to improve. You are not alone — there are many resources to help you live well with Parkinson's.
