Parkinson symptoms in older adults

Overview

Parkinson's disease is a brain condition that affects movement. It happens when cells in the brain that make a chemical called dopamine (doh-PUH-meen) are gradually lost. Dopamine helps control movement and balance. With less dopamine, the brain cannot send signals properly, causing shaking, stiffness, and coordination problems.

Yes. Parkinson's is one of the most common nervous system disorders worldwide. It becomes much more common with age.

Most people diagnosed with Parkinson's are over 60. The average age at diagnosis is around 60. It affects both men and women, but slightly more men.

Symptoms

Common symptoms

• A tremor, or shaking, in a hand, arm, or leg, especially when at rest.
• Slowness of movement (bradykinesia).
• Muscle stiffness in the arms, legs, or neck.
• Balance and coordination problems.
• Smaller handwriting than usual (micrographia).
• Reduced arm swing on one side when walking.
• A quiet, soft voice.
• A masked, expressionless face (hypomimia).
• Difficulty walking or feeling as though one foot is stuck to the floor.

Symptoms in children

• Parkinson's disease is extremely rare in children. This article focuses on symptoms in older adults.

Symptoms in older adults

• Falls are more common due to balance issues and weaker muscles.
• A sudden 'freezing' sensation where the feet feel glued to the floor.
• More severe stiffness and rigidity.
• Sleep problems, including acting out dreams (REM sleep behavior disorder).
• Urinary urgency or frequency.
• Trouble swallowing or chewing as the disease progresses.
• Thinking and memory changes, including dementia in later stages.

Causes

Main causes

• The exact cause is not known.
• A loss of dopamine-producing neurons in the substantia nigra (a small area in the brain).
• A combination of genetic changes and environmental triggers (such as exposure to certain pesticides) is thought to play a role.

Risk factors

• Advancing age (most common risk factor).
• Having a close relative with Parkinson's (slightly increases risk).
• Being male.
• Exposure to certain chemicals, such as pesticides or heavy metals.
• Head injuries (some research suggests a link).

When to see a doctor

See a doctor urgently if:

• If you or someone you know has sudden, severe difficulty with movement, speech, or swallowing.
• If confusion or fainting occurs with no obvious cause.
• If you experience a head injury from a fall and have new symptoms.

Book a routine appointment if:

• If you have a tremor that doesn't go away, stiffness, or slowness that affects daily activities.
• If you notice a change in your walking, balance, or speech.
• If a family member or friend notices a masked face or decreased arm swing.

Diagnosis

A doctor will take a detailed medical history and perform a physical and neurological exam. They will watch how you move, check your reflexes, and see if you have a tremor or stiffness. You may be referred to a neurologist (a brain and nerve specialist).

Tests that may be done

• Blood tests to rule out other conditions.
• Brain imaging, such as an MRI (magnetic resonance imaging).
• Sometimes a DaTscan (dopamine transporter scan) to measure dopamine activity in the brain.

What to expect at your appointment

Parkinson's is diagnosed based on symptoms and a careful exam. There is no single test that can confirm it with 100% certainty. The doctor may check your response to Parkinson's medication over a trial period. It can take time and multiple visits to be sure.

Treatment

Treatment focuses on reducing symptoms and helping you stay as active and independent as possible. There is no cure, but many people do well with treatment for years.

Self-care at home

• Exercise every day to improve balance, strength, and mood (speak to your doctor first).
• Make your home safer by removing rugs, adding grab bars, and improving lighting.
• Keep a routine and set realistic daily goals.
• Rest when you feel tired, and pace your activities.
• Talk to your healthcare team about aids like walking sticks or special handrails.

Medical treatments

Medications can replace dopamine or help it stay active in the brain. These medicines can improve movement and reduce tremor, but they are not a cure. Side effects can occur, so your doctor will monitor you closely. Physical, occupational, and speech therapy are also very helpful. Therapists can teach you ways to move safely, manage daily tasks, and speak more clearly.

When is surgery considered?

For some people with advanced Parkinson's whose symptoms no longer respond well to medication, deep brain stimulation (DBS) may be considered. This surgery involves placing a small device in the chest that sends electrical signals to specific brain areas. A specialist team will decide if you are a suitable candidate.

Living with this condition

Living with Parkinson's means learning to adjust. Simple daily activities may take longer, but with support and planning, many people continue to enjoy life. Break big tasks into steps, use adaptive tools, and allow plenty of time.

Lifestyle tips

• Stay socially active to avoid isolation.
• Keep your brain engaged with puzzles, reading, or learning new skills.
• Manage stress with deep breathing or meditation.
• Get support from family, friends, and people who understand Parkinson's.
• Talk openly with your healthcare team about any changes.

Diet and exercise

Eat a balanced diet rich in fruits, vegetables, whole grains, and fiber to prevent constipation. Drink plenty of fluids. Exercise can improve walking, balance, and quality of life. Options include walking, gentle stretching, yoga, or resistance training. Always check with your doctor before starting a new exercise programme. If swallowing is a problem, a speech and language therapist can give you advice on food textures and exercises.

Mental health and emotional wellbeing

It is completely normal to feel scared, sad, or anxious after a diagnosis. Parkinson's can affect mood and thinking. Depression and anxiety are common. Talk to your doctor about mental health support. Remember that seeking help is a sign of strength, not weakness.

Prevention

There is no proven way to prevent Parkinson's disease. Some research suggests that regular physical activity and eating a healthy plant-based diet may lower the risk, but more studies are needed. For people who already have Parkinson's, exercise and lifestyle changes can slow down disability and improve well-being.

Complications

If left untreated

• Untreated Parkinson's may lead to falls and fractures.
• Difficulty swallowing increases the risk of choking and pneumonia (a serious lung infection).
• Severe stiffness can lead to bedsores and blood clots.
• Thinking and memory problems can affect independence.

Long-term outlook

Many people with Parkinson's live long, fulfilling lives. Medications and therapies can control symptoms for many years. Life expectancy is close to that of people without Parkinson's, especially with good medical care and family support. The disease is different for everyone, and your doctor can help you plan for the future.
