Parkinson’s disease is a neurological disorder that progresses slowly and affects movement and coordination. It is estimated that around 10 million people worldwide are living with the condition. Parkinson’s often begins with subtle symptoms, such as a tremor in the hands or changes in posture. While it is more common in older adults, it can also affect people at a younger age.
This blog is a complete guide to understanding Parkinson’s, its stages, symptoms, causes, and the treatments that are available. We will also cover what you need to know about living with Parkinson’s disease and how ongoing research is shaping a more hopeful future.
Synopsis
What is Parkinson’s Disease?
Parkinson’s disease is a progressive disorder of the central nervous system that is chronic and primarily affects movement. It occurs when nerve cells in a region of the brain called the substantia nigra, which controls movement, become damaged or die. These cells are responsible for producing a chemical messenger called dopamine, which is essential for smooth, coordinated muscle movement.
Dropping dopamine levels disrupts the communication between different parts of the brain. This is precipitated in the form of disrupted motor functions such as tremors and weakness, seen in people with Parkinson’s.
Key facts about the condition:
-
Parkinson’s disease in the elderly is more common, typically beginning around age 60, though early-onset cases can occur before 50.
-
The condition affects both men and women but is slightly more prevalent in men.
-
It is not contagious or inherited in most cases, though genetics may play a role in a small percentage of patients.
-
The disorder progresses in stages and affects individuals differently.
Signs and Symptoms of Parkinson’s Disease
The Parkinson’s symptoms appear gradually and are mild in the initial stages. Over time, they progress and start to interfere with daily activities. These symptoms are broadly divided into motor and non-motor types. These early symptoms are easy to dismiss or attribute to ageing. However, recognising the early signs of Parkinson’s disease can lead to timely diagnosis and better management of the condition.
Motor symptoms include:
-
Tremors: Usually seen in the hands or fingers when the body is at rest. It is often one of the first symptoms to appear.
-
Muscle Rigidity: Stiffness in the limbs or trunk that can limit the range of motion and cause discomfort.
-
Bradykinesia: A noticeable slowing down of movement, which makes even simple tasks take longer than usual.
-
Instability in Posture: Impaired balance and coordination, leading to frequent falls or a stooped posture.
Non-motor symptoms can appear before the motor signs and may go unnoticed:
-
Loss of sense of smell (anosmia)
-
Sleep disturbances such as REM sleep behaviour disorder
-
Depression and anxiety
-
Difficulty concentrating or mild memory problems
Causes and Risk Factors
Understanding what causes Parkinson’s disease helps in identifying individuals who may benefit from early screening and monitoring. Although the exact reason why Parkinson’s disease develops is still not fully understood, it is believed to result from a combination of genetic and environmental factors that cause loss of dopamine-producing neurones in the brain.
Some known risk factors include:
|
Age |
The risk increases significantly after the age of 60. |
|
Gender |
The condition is slightly more common in men than in women. |
|
Genetic mutations |
Certain inherited changes, such as LRRK2 and PARK7, have been associated with familial forms of Parkinson’s. |
|
Environmental exposures |
Long-term exposure to pesticides, herbicides, or industrial toxins may raise the risk in some individuals. |
|
Head trauma |
A history of repeated head injuries has been linked to higher Parkinson’s risk. |
Diagnosis: When to See a Doctor?
Parkinson’s cannot be confirmed with a single robust test. Diagnosis is mainly done based on clinical evaluation. A neurologist assesses symptoms, medical history, and neurological function to make a determination. When early warning signs of Parkinson’s, such as tremors or slowed movement, appear, it is considered in the diagnosis.
Key steps in diagnosis include:
-
Neurological Examination: This involves checking reflexes, muscle tone, coordination, and balance. The doctor may observe facial expressions, hand movements, and walking patterns.
-
Medical History: Details about symptom onset, progression, and family history are important for making an accurate diagnosis.
-
Imaging Tests: tools like MRI or DaTscan can help rule out other conditions that mimic its symptoms.
Treatment Options
Currently, there is no cure for Parkinson’s. However, multiple treatments are available to manage symptoms and improve quality of life. Treatment approaches are personalised and include a combination of medications, therapies, and sometimes surgery.
Medications commonly prescribed include:
-
Levodopa/carbidopa: This is the most effective drug for controlling motor symptoms by replenishing brain dopamine levels.
-
Dopamine agonists: These mimic the action of dopamine in the brain.
-
MAO-B inhibitors: They slow the breakdown of dopamine and help improve motor function.
Non-drug therapies include:
-
Physical therapy to maintain mobility and balance
-
Occupational therapy for daily activities and independence
-
Speech therapy for voice and swallowing issues
Surgical option:
Deep brain stimulation for Parkinson’s may be considered in cases where symptoms are not well-controlled with medication. It involves implanting electrodes into specific areas of the brain to regulate abnormal activity.
Supportive options for regular treatment:
Lifestyle changes such as regular exercise, a balanced diet, and stress reduction. The best treatment for Parkinson’s disease often combines a multidisciplinary team working together to address the changing needs of the patient.
Living with Parkinson’s: Coping and Support
Adjusting to life with Parkinson’s disease requires both physical and emotional adaptation. Medications and therapy manage physical symptoms. But for long-term care, it’s crucial to build the right support systems.
Important support systems include:
-
Emotional well-being: Depression and anxiety are common. Counselling, medication, and mindfulness practices may help manage mental health.
-
Caregiver Involvement: Family members and caregivers play a critical role in monitoring changes and assisting with daily activities.
-
Support Networks: Joining Parkinson’s caregiver support groups or patient communities offers a valuable connection and motivation.
-
Adaptation Strategies: Using assistive devices to help with communication and simplifying home layouts can help them maintain independence.
Hope for the Future: Research and Advancements
Advances in neuroscience and technology are giving a promising outlook for Parkinson’s disease. Several research directions are offering new strategies to slow progression and improve quality of life.
-
Neuroprotective therapies: Ongoing trials are focused on protecting dopamine-producing neurons from further damage. These include calpain inhibitors and anti-inflammatory agents that may reduce oxidative stress and inflammation in the brain. Cutting down these two key contributors to nerve cell degeneration can significantly slow down the progression of the disease.
-
Stem cell therapy and regenerative medicine: Researchers are exploring the use of lab-grown dopamine neurons derived from stem cells. These can be used to replace those lost to the disease’s progression. Transplanting these cells into targeted brain regions may restore function and reduce symptoms. It is still experimental, but it has a lot of promise.
-
Gene therapy trials: Targeted therapies are now being developed for individuals with known genetic mutations such as LRRK2 and PARK7. These therapies aim to either correct the faulty gene expression or reduce the harmful effects of the abnormal proteins they produce. Gene-based approaches are currently in clinical trials and can soon make a difference to personalised medicine for Parkinson’s.
-
AI and wearable technologies: Smart wearable devices are being used to track tremors, mobility changes, and medication response continuously throughout the day. Integrated with AI tools, these systems can provide clinicians with real-time data to personalise treatment plans.
Conclusion
Parkinson’s disease affects each person differently, but what remains constant is the value of early recognition and timely care. From subtle early symptoms to advanced treatment options, understanding the condition can make a meaningful difference.
