Parkinson symptoms screening test preparation

Overview

Parkinson’s disease is a condition of the brain that gradually causes movement problems. It happens when certain nerve cells stop working properly and no longer make enough of a chemical called dopamine, which helps control movement. Over time, this can lead to shaking, stiffness, and trouble with balance and coordination.

Parkinson’s is one of the most common neurological conditions affecting older adults. It is estimated that about 1 in 500 people in the UK have Parkinson’s, and the number increases with age.

It most often develops in people over the age of 60, but around 1 in 20 people with Parkinson’s are diagnosed before age 50. Men are slightly more likely to be affected than women.

Symptoms

Common symptoms

• Tremor (shaking) in a hand, arm, or leg, especially when at rest.
• Stiffness in the limbs, neck, or trunk that makes movement difficult.
• Bradykinesia (slowness of movement), which can make simple tasks like buttoning a shirt harder.
• Impaired balance and coordination, leading to a shuffling walk or falls.
• Changes in handwriting, such as smaller, cramped letters (micrographia).

Symptoms in children

• Parkinson’s is extremely rare in children. When it does occur, it is often linked to a genetic cause. Symptoms may include early-onset dystonia (involuntary muscle contractions), slowness, and tremor.

Symptoms in older adults

• In older adults, the typical motor symptoms (tremor, stiffness, slowness) are the most common. They may also experience non‑motor symptoms like depression, sleep problems, and memory changes.

Causes

Main causes

• Parkinson’s is caused by the gradual loss of dopamine‑producing nerve cells in a part of the brain called the substantia nigra. The exact reason why these cells die is not fully understood.
• In most cases, there is no single known cause; it is likely a combination of genetic and environmental factors.

Risk factors

• Age: risk increases with age, especially after 60.
• Genetics: having a close relative with Parkinson’s slightly raises the risk, but most cases are not inherited.
• Environmental exposures: long‑term exposure to certain pesticides or chemicals may increase risk, but this is not proven for everyone.

When to see a doctor

See a doctor urgently if:

• If you experience a sudden, severe worsening of symptoms that affects your ability to care for yourself.
• If you have a fall that causes a head injury or you cannot get up.
• If you have new hallucinations, confusion, or a fever with muscle rigidity.

Book a routine appointment if:

• If you notice a persistent tremor, stiffness, or slowness that is affecting your daily activities.
• If you have trouble walking, balancing, or performing fine motor tasks like writing or buttoning clothes.

Diagnosis

There is no single test for Parkinson’s disease. Diagnosis is based on your medical history, a thorough neurological examination, and how your symptoms develop over time. A specialist, usually a neurologist, will assess your movement, coordination, and reflexes.

Tests that may be done

• Neurological exam: checks for tremor, stiffness, balance, and walking.
• Response to Parkinson’s medication: improvement with a trial of dopamine‑like medications can support the diagnosis.
• DaTscan (dopamine transporter scan): a special imaging test that can help differentiate Parkinson’s from other conditions, but it is not used routinely.
• Other tests (blood tests or MRI) may be done to rule out other causes of your symptoms.

What to expect at your appointment

For screening or preparation, your doctor will give you specific instructions if any tests are needed. For a DaTscan, you may be asked to avoid certain medications or caffeine beforehand. Usually, no special preparation is needed for the basic neurological exam. The process can take time, and your doctor may want to see you more than once to see how symptoms change.

Treatment

Treatment for Parkinson’s aims to manage symptoms and keep you as active and independent as possible. It often involves a combination of medication, therapy, and lifestyle changes tailored to your needs.

Self-care at home

• Stay physically active with exercises like walking, swimming, or tai chi to improve strength and balance.
• Eat a balanced diet with plenty of fruits, vegetables, and fibre to help with digestion.
• Get enough rest and practice good sleep habits.
• Use assistive devices such as a walking stick or grab bars if needed.

Medical treatments

Medications that increase dopamine levels or mimic its action in the brain are the mainstay of treatment. Your doctor will work with you to find the right type and dose. Other treatments include physiotherapy, occupational therapy, and speech therapy to help with movement, daily tasks, and communication.

When is surgery considered?

Deep brain stimulation (DBS) may be considered for people with advanced Parkinson’s whose symptoms are not well controlled by medication. DBS involves implanting electrodes in certain parts of the brain to help regulate abnormal signals.

Living with this condition

Living with Parkinson’s can mean adapting your daily routines. Simple changes—like dressing in loose‑fitting clothes, using utensils with larger handles, and allowing extra time for activities—can make a big difference. Planning your day around when medications work best can also help.

Lifestyle tips

• Stay connected with friends and family—social activities can improve mood and reduce isolation.
• Find enjoyable hobbies that match your abilities, such as art, music, or gentle gardening.
• Manage stress through relaxation techniques like deep breathing or meditation.

Diet and exercise

A balanced diet rich in fibre, whole grains, and lean protein supports overall health. Some people notice that protein can affect how well certain medications work, so they separate high‑protein meals from medication times. Regular exercise—especially activities that challenge balance and flexibility—can help maintain mobility and reduce falls.

Mental health and emotional wellbeing

Depression, anxiety, and apathy are common in Parkinson’s. These are part of the condition, not a personal failing. Talk to your doctor if you feel down or worried—counselling, support groups, and sometimes medication can help.

Prevention

Currently, there is no proven way to prevent Parkinson’s disease. Research is ongoing, but no specific changes in diet, exercise, or supplements have been shown to stop it from developing.

Complications

If left untreated

• Worsening of motor symptoms, making daily activities much harder.
• Increased risk of falls and fractures from balance problems.
• Swallowing difficulties, which can lead to choking or aspiration pneumonia.
• Cognitive changes, including dementia in some advanced cases.

Long-term outlook

Parkinson’s is a progressive condition, meaning symptoms can get worse over time. However, with modern treatments and support, many people continue to enjoy a good quality of life for many years. Everyone’s experience is different, and your healthcare team will help you manage symptoms and plan for the future. There is reason to remain hopeful.
