Understanding the Early Signs of Parkinson's: What People Often Miss

Parkinson's Awareness Day is a great opportunity to highlight this progressive neurological disorder that affects movement. Caused by a reduction in dopamine-producing cells in the brain, the disease develops gradually, and symptoms can vary significantly from person to person.

While many people associate Parkinson's with tremor, stiffness or slowness of movement, these are generally late symptoms and in fact, early signs can be subtle, easily overlooked, and pre-date diagnosis for many years.

Some of the more subtle symptoms can include:

1. Changes in sense of smell

A reduced or lost sense of smell (anosmia) is one of the earliest reported symptoms, sometimes appearing years before movement-related issues.

2. Sleep disturbances

Acting out dreams (known as REM sleep behaviour disorder), restless sleep, or frequent waking can be early indicators.

3. Subtle changes in handwriting

Handwriting may become smaller (micrographia) and more cramped over time.

4. Reduced facial expression

Sometimes described as a "masked face," this can make someone appear less expressive or animated.

5. Low mood or anxiety

Depression and anxiety can precede physical symptoms and are part of the condition—not just a reaction to it.

6. Constipation

Persistent constipation, unrelated to diet or lifestyle changes, is a commonly overlooked early feature.

7. Softer or quieter voice

People may notice their voice becoming softer, hoarser, or more monotone.

What should you do if you notice these symptoms?

It's important to emphasise that experiencing one or even several of these symptoms does not mean you have Parkinson's disease. Many of these signs are common and can be caused by a range of benign or treatable conditions.

However, if you notice persistent changes, particularly a combination of symptoms, it's sensible to seek medical advice.

Your GP is the best first step. They can:

• Take a thorough history
• Assess your symptoms in context
• Rule out more common causes
• Arrange further investigations or specialist referral if appropriate

Why early assessment matters

While there is currently no cure for Parkinson's, early diagnosis can make a meaningful difference. It allows for:

• Better symptom management
• Access to supportive therapies
• Improved long-term planning and quality of life

A balanced approach to awareness

Awareness is about being informed—not alarmed. The goal is not to encourage self-diagnosis, but to empower individuals to recognise when something may be worth discussing with a healthcare professional.

If you have any concerns about symptoms—whether related to Parkinson's or otherwise—our GP team is here to provide clear, personalised guidance in a supportive and confidential setting.

If in doubt, get checked. Early reassurance is just as valuable as early diagnosis.
