Understanding a Parkinson’s diagnosis begins with recognising the gradual onset of symptoms. 

While the diagnosis of Parkinson’s may take time, especially considering the subtlety of some symptoms, each step brings you closer to a tailored treatment plan that maintains independence and overall wellbeing.

Who gets Parkinson’s?

Parkinson’s doesn’t discriminate by age or gender; it can affect anyone. Even very rare cases of juvenile Parkinson’s exist. While most cases of Parkinson’s are diagnosed in people over 60, 1 in 5 Australians living with Parkinson’s were diagnosed under the age of 50 (1). This is referred to as young onset Parkinson’s.

Getting a clear and accurate diagnosis of Parkinson’s, especially in the early stages, can be challenging, and remains an area of ongoing research and clinical focus.Right now there is no biomarker (e.g.blood test or scan) for diagnosing Parkinson’s so it relies on a clinical diagnosis by a GP or neurologist.

You could participate in a genetic study and with any family history or young onset diagnosis suspected, that data would be very useful to the study. https://www.qimrberghofer.edu.au/apgs/. However only about 10% of PD cases are linked to genes currently.

Below is an adapted questionnaire from the Michael J Fox Foundation which aims to help people determine if you should speak to your GP or geriatrician about investigating a Parkinson’s diagnosis.

If you answer yes to any one of these early symptoms, it does not mean you may have Parkinson’s. However, if you answer yes to several of the questions below, discuss these changes with your GP and decide if there are any next steps. Talk to your GP even if you answer no to most of these questions but feel that something is not quite right, for example, your mood or mobility have changed, and this affects your quality of life. Also take note if any of the movement symptoms start on one-side of the body or both.

      1. Do you have chronic constipation (less than 3 movements a week)?
      2. Have you experienced a reduced or complete loss of your sense of smell?
      3. Do you have unexplained mood changes, especially anxiety, depression and/or apathy?
      4. For young onset (under 50 years old), typically have you experienced more unexplained back/shoulder pain (e.g. frozen shoulder or unexplained shoulder pain that isn’t relieved by physiotherapy)?
      5. Have you been getting slower in your usual daily activities? (e.g. noticeable movements like moving a mouse or typing)?
      6. Is your handwriting getting smaller or illegible?
      7. Is your speech slurred or softer? Do people ask you to speak up even though you do not notice a change in your voice volume?
      8. Do you have trouble rising from a chair, rolling over or getting out of bed?
      9. Do your lips, hands, arms and/or legs shake? Does your finger twitch?
      10. Have you noticed more overall body stiffness?
      11. Do you have trouble fastening buttons, tying your shoelaces or getting dressed?
      12. Do you shuffle your feet and/or take smaller steps when you walk? TIP: Get your shoes out and look at the bottoms of them. You may notice uneven wear on the soles of your shoes.
      13. Do your feet seem to get stuck to the floor when walking or turning?
      14. Have you or others noticed that you don’t swing one arm when walking?
      15. Do you have more trouble with your balance?
      16. Have you or others noticed that you stoop or have abnormal posture?
      17. Do you blink less, or do people think you are staring or disinterested in what they are saying?
      18. Have you, your coworkers or your loved ones noticed a lack of facial expression?
      19. Do you have sleep issues, like acting out your dreams or yelling (RBD), feel like your legs need to move (RLS), get up many times at night to wee (nocturia) or can’t fall asleep or stay asleep easily?

If you want to discuss these changes with your GP or if you have noticed a loved one facing some of these difficulties, print these questions out as a conversation starter.

The earlier you get a diagnosis, the earlier you can start interventions that keep you well for longer.

How do they diagnose Parkinson’s?

No widely available test currently exists to definitively diagnose Parkinson’s. Diagnosis traditionally relies on clinical observations, particularly identifying four cardinal motor symptoms:

  1. slowness of movements (bradykinesia)
  2. muscle stiffness (rigidity)
  3. stiffness and slowness can result in falls and balance issues later on
  4. tremors occur in around 75% of cases, with the majority being the stereotypical, pill-rolling, resting tremor; some people with Parkinson’s have no tremor at all.

Specialised medical diagnosis involves consultations with a GP. Sometimes, early symptoms may go unrecognised, like changes in handwriting, loss of sense of smell, constipation or shoulder pain and can lead to delays in diagnosis. Initial assessment looks at your motor and non-motor symptoms, medical history, exposure to potential toxins and family history.

If recommended, you may be referred to a neurologist or geriatrician to have a neurological examination to confirm symptoms and rule out other conditions. A genetic test may be recommended, but only a fraction of cases involve known gene mutations. The majority of Parkinson‘s cases are idiopathic, or of unknown causes, emphasising the complexity of tracking the causes the condition.

The introduction of levodopa, a dopamine precursor and often first line medication for managing motor symptoms, is a significant aspect of both treatment of motor symptoms and diagnosis of Parkinson’s (2, 5).

What happens during a diagnosis?

Again, there is no single test that can confirm Parkinson’s that is widely available now. Diagnosis is based on a detailed clinical assessment by a GP, Geriatrician or neurologist, who will review your symptoms, medical history and movement changes.

During the assessment, the neurologist may examine:

  • Reflexes & muscle tone
  • Coordination & balance
  • Hand & finger movements
  • Walking & posture

In some cases, additional tests may be recommended to support the diagnosis or rule out other conditions with similar symptoms. These may include:

  • DaTscan (dopamine transporter scan) is an imaging test that measures dopamine activity in the brain and may help distinguish Parkinson’s from other movement disorders.
  • MRI or CT scans can be used to exclude other neurological conditions, such as stroke, brain tumours or structural changes in the brain.
  • Blood tests can be used to identify or rule out other medical conditions that can cause symptoms similar to Parkinson’s.

What is Parkinson’s doing to me?

Parkinson’s is highly complex and very individual. Each person experiences a unique combination of a possible 40 or more symptoms, though not all of them. It is now recognised as a whole-body disorder (2), resulting from the gradual loss of dopamine and other brain chemicals that help send messages from your brain to your body.

It may affect your sleep, mood, motivation, vision, your gastrointestinal system and your movements. The lack of dopamine makes your body slower and stiffer, altering the way you walk and talk. Loss of facial expressions and reduced blinking are also common. These motor symptoms are treatable with Parkinson’s medications like dopamine replacement, regular physical activity and a healthy lifestyle.

Decades prior to movement problems people may experience constipation, changes to handwriting, and loss of or a reduced sense of smell. Unexplained anxiety, depression, and apathy may appear, underlining the need for a holistic approach to wellbeing and earlier recognition of these ‘prodromal’ symptoms. 

A multidisciplinary care team can help you maintain your independence and give you the best medications and strategies to manage your symptoms.

What should I do next?

Reactions to a Parkinson’s diagnosis can range from acceptance to fear and anger to denial and disbelief. Some people feel relief after seeking a diagnosis for such a long time. Getting support in place early is a great idea, recognising that the emotional impacts often outweigh your physical limitations early on. Adjusting to these life changes requires time, acceptance, and setting realistic expectations for you and others. Reach out to friends, family, colleagues, support groups and allied health professionals. Seminars, webinars, and information from trusted sources can help guide you through this journey. Be wary of sites selling things and not citing scientific research papers.

Maintain your self-identity, don’t define yourself by Parkinson’s. Disclosing the Parkinson’s diagnosis to your workplace, friends or family is a personal choice, yet openness may bring relief and lower the stress of trying to hide your symptoms. It is a reportable driving medical condition, so contact your driving authority in your state or territory to get the necessary forms. 

It is highly recommended to apply for NDIS support as soon as possible if 65 and under. See our Step by Step NDIS information sheets on the web and go to the YOPX website for more articles and helpful tips on what to include in your application. Once you are on NDIS you can stay on NDIS. But if you don’t apply for support until you are over 65, My Aged Care (MAC) can provide financial assistance for the increased costs of managing this condition but it is means tested and does not have the same allowances as NDIS. 

Our top 5 wellness tips

Parkinson’s affects many different systems in the body and can vary greatly from person to person, changing significantly over time. Regular check-ups by health professionals are crucial, not only for diagnosing Parkinson’s early but also for managing it as it progresses. This is especially important for dealing with non-movement symptoms like depression, constipation, pain, and sleep problems.

To help people with Parkinson’s live as well as possible and stay independent, a care team effort is essential. This means involving GPs, specialists like neurologists, and other allied health professionals working together in a co-ordinated way.

Treatment can begin right away with some lifestyle changes to improve your overall wellness. Exercise is the number one best thing you can do for Parkinson‘s. It has been shown to slow progression (6).

Healthy lifestyle, good nutrition, keeping well hydrated, practising good sleep hygiene, and staying socially connected are our five favourite and easy tips to stay well and help reduce symptoms.

Your care team

Building a care team early is essential. Involve General Practitioners, physiotherapists, speech pathologists, occupational therapists, mental health specialists and others who will help you treat your most bothersome symptoms. If available, early self-referral to a Parkinson’s Nurse Specialist through your state or territory Parkinson’s Organisation can be invaluable.

Your GP may be able to help by getting you on a Mental Health Plan and/or Chronic Disease Management Plan to access these subsidised allied health professional supports.

If eligible*, your GP can also refer you for a Home Medications Review (HMR) where your pharmacist will come to your home to check your prescriptions and supplements for interactions and discuss with you how and when to take them to get the best results if you are finding this difficult. (*Patient eligibility: you must satisfy the following mandatory HMR Service Eligibility Criteria including being a current Medicare or DVA cardholder or is a person who is eligible for a Medicare card; be living in a community setting; are at risk of, or experiencing, medication misadventure; your GP/Referrer confirms that there is an identifiable clinical need for a HMR Service.)

Supports

Look to your local Parkinson’s organisation and government programs for early support in accessing the therapies and other help you may need to maintain your quality of life while dealing with this life-changing diagnosis.
