Parkinson’s disease is a neurodegenerative disorder that affects millions of people worldwide. In Spain, it is estimated that over 160,000 people live with this condition.
Recognising the early symptoms of Parkinson’s is crucial for an early diagnosis and starting the appropriate treatment. This article explains the most common initial symptoms of Parkinson’s disease and the importance of detecting them early.
What is Parkinson’s Disease?
Before discussing the symptoms, it is essential to understand what Parkinson’s disease is and how it affects those who suffer from it. It is a neurodegenerative disorder that progressively affects the nervous system and, consequently, movement. The disease occurs when neurons in a specific part of the brain, called the substantia nigra, which produce dopamine—a neurotransmitter essential for controlling body movements—begin to degenerate. This decrease in dopamine leads to the characteristic symptoms of the disease, such as slowness of movement, tremors, and rigidity, as well as other non-motor symptoms that also impact the patient’s daily life.
Early Symptoms of Parkinson’s You Should Know
Parkinson’s disease can begin subtly, with symptoms that are often overlooked in the early stages. Identifying these symptoms can help seek early medical evaluation and proper management of the disease. Below, we explain the most common initial symptoms to watch out for:
- Resting tremor: Tremor is one of the most characteristic symptoms of Parkinson’s. It usually starts in one hand or finger when the affected part rests. This tremor may spread to other parts of the body over time. However, it does not always have to be present for a Parkinson’s diagnosis.
- Muscle rigidity: This can cause discomfort pain, and limit the range of motion. Rigidity can affect any body part and is often more noticeable when moving the joints.
- Bradykinesia (slowness of movement): Bradykinesia refers to the slowing down voluntary movements. This symptom can make daily activities such as walking, whisking eggs, or buttoning a shirt more difficult.
- Changes in handwriting: Micrographia is an alteration that manifests as smaller and more cramped writing than usual. This can make handwriting harder to read.
- Sleep disturbances: Problems such as insomnia or sudden movements during REM sleep, as if acting out dreams can be early signs of Parkinson’s. These symptoms may appear years before motor problems become evident.
- Loss of smell: Partial or total loss of the sense of smell, known as hyposmia or anosmia, is one of the symptoms that can appear years before other more noticeable symptoms.
- Other non-motor symptoms: Constipation and mood changes (such as depression), among others, can also appear years before more prominent motor symptoms.
Why is it Important to Recognise Early Symptoms of Parkinson’s?
Identifying the early symptoms of Parkinson’s is crucial for several reasons:
- Facilitates early diagnosis: The sooner the disease is diagnosed, the sooner treatment can begin.
- Improves prognosis: Early treatment can help maintain quality of life and delay the progression of symptoms.
- Provides opportunities to participate in clinical trials: Patients diagnosed in the early stages may have more options to participate in studies of new treatments.
- Allows for future planning: An early diagnosis enables patients and their families to plan and adapt better to the changes brought by the disease.
Stages of Parkinson’s Disease
Parkinson’s disease is a progressive condition and develops in several stages over time. Understanding these stages can help patients and their families or caregivers prepare for the changes that may occur. Below, we explain the different stages of the disease and how they can affect daily life:
- Early stage: Symptoms are mild and usually affect only one side of the body. At this stage, symptoms typically do not significantly interfere with daily activities.
- Moderate stage: Symptoms become more pronounced and affect both sides of the body. Balance problems may arise, increasing the risk of minor falls, and performing everyday tasks may require more time and effort.
- Advanced stage: Symptoms severely affect mobility and independence, significantly limiting the patient’s autonomy. Complications such as frequent falls, freezing while walking, and speech and swallowing difficulties may appear.
It is important to remember that the progression of the disease varies greatly from person to person, and proper treatment can help manage symptoms at all stages.
What to Do if You Suspect You Have Parkinson’s Symptoms?
If you notice one or more of the symptoms mentioned, it is crucial to consult a neurologist. The diagnosis of Parkinson’s is primarily based on clinical evaluation. Your specialist will likely perform the following tests:
- A detailed assessment of your symptoms and medical history.
- A complete physical and neurological examination.
- Additional tests may be needed to rule out other conditions.
Treatment of Parkinson’s
Although there is no cure for Parkinson’s, several treatments are available to help manage symptoms and improve quality of life:
- Medications: Various drugs can help control symptoms. Your doctor will assess the most suitable treatment for you, adjusting the dosage and type of medication over time according to your needs.
- Physical and occupational therapy: These therapies can help you maintain mobility, flexibility, and independence in daily activities. Physiotherapists and occupational therapists can design specific exercises tailored to your needs, allowing you strengthen your body and perform daily tasks more safely and comfortably.
- Speech therapy: Speech therapy can be beneficial if you experience difficulties speaking or swallowing. A speech therapist specialising in neurological disorders can teach you techniques to improve your pronunciation, voice volume, and swallowing coordination, helping you communicate clearly and enjoy meals without worries.
- Advanced treatments: In some cases, when symptoms are not adequately controlled with medication, more advanced procedures may be considered, such as deep brain stimulation (DBS). This surgical procedure involves implanting electrodes bilaterally to modulate certain brain parts, helping reduce motor symptoms. It is an option only recommended after a detailed evaluation by a specialist.
- Focused ultrasound therapy: Another advanced treatment is high-intensity focused ultrasound.
- Lifestyle changes: Adopting a balanced diet and exercising regularly can help you manage Parkinson’s symptoms and maintain your overall well-being. Exercise, in particular, can improve mobility, balance, and mood, while a good diet contributes to having more energy and better managing the effects of medication.
Research and Advances in Parkinson’s Treatment
Research on Parkinson’s continues to advance. Some of the most promising fields include:
- Neuroprotective therapies: Treatments aimed at slowing or halting the progression of the disease.
- Gene therapy: Research exploring how to modify genes to treat or even prevent Parkinson’s disease.
- Stem cells: Studies investigating the possibility of regenerating lost neurons through stem cells.
- Biomarkers: Development of tests that allow for earlier and more accurate diagnosis, facilitating personalised treatment.
- Ultrasound therapies: Both high- and low-intensity ultrasound therapies are used for therapeutic lesions, neuromodulation of different brain regions, or opening the blood-brain barrier to allow the passage of specific medications.
The Importance of Early Detection
Recognising the early symptoms of Parkinson’s is essential for obtaining an early diagnosis and starting treatment as soon as possible. Although receiving a Parkinson’s diagnosis can be overwhelming, it is necessary to remember that, with the proper treatment, many people with this condition lead entire and active lives for many years.
