Understanding Parkinson's Disease: Recognising the Symptoms

Parkinson's disease (PD) is a neurodegenerative disorder that affects movement control. It occurs when there is a loss of dopamine-producing cells in the part of the brain called the substantia nigra, leading to a variety of motor and non-motor symptoms. While there is no cure for Parkinson's disease, early detection and treatment can significantly improve the quality of life for those affected. In this blog, we will delve into the symptoms of Parkinson's disease and explore ways to spot them.

1. Motor Symptoms: Motor symptoms are the hallmark signs of Parkinson's disease and generally appear gradually over time. These symptoms affect movement and may include:

a) Tremors: Tremors are involuntary shaking or trembling movements, usually starting in the hands, fingers, or feet. The tremors are typically present at rest and may disappear or decrease with voluntary movement.

b) Rigidity: Rigidity refers to stiffness or inflexibility of the muscles, making it difficult to move. It may affect any part of the body and can cause discomfort or pain.

c) Bradykinesia: Bradykinesia refers to slowness of movement, making routine tasks such as buttoning a shirt or brushing teeth challenging. It may also affect facial expressions, resulting in a reduced range of facial movements.

d) Postural instability: Postural instability refers to difficulty in maintaining balance and posture, leading to a stooped or hunched posture and an increased risk of falls.


2. Non-Motor Symptoms: In addition to motor symptoms, Parkinson's disease can also cause non-motor symptoms, which may occur before or after the onset of motor symptoms. These symptoms may include:

a) Sleep disturbances: Parkinson's disease can disrupt sleep patterns, causing insomnia, vivid dreams, restless leg syndrome, and sleep apnea.

b) Depression and anxiety: Many people with Parkinson's disease experience mood changes, including depression, anxiety, and irritability.

c) Cognitive changes: Parkinson's disease can also affect cognitive function, including memory, attention, and problem-solving skills.

d) Loss of sense of smell: A reduced ability to smell or taste is often an early sign of Parkinson's disease.

e) Constipation and urinary problems: Parkinson's disease can affect the autonomic nervous system, leading to digestive issues, constipation, and urinary problems.


3. Ways to Spot the Symptoms: Early detection of Parkinson's disease can be challenging as the symptoms may vary from person to person, and some of the symptoms may be attributed to other conditions. However, being aware of the following warning signs can help in spotting the symptoms of Parkinson's disease:

a) Pay attention to changes in movement: If you or a loved one notice tremors, stiffness, slowness of movement, or difficulties with balance and posture, it may be a sign of Parkinson's disease.

b) Monitor changes in mood and cognition: If you or a loved one experience unexplained mood changes, cognitive difficulties, or sleep disturbances, it may be indicative of Parkinson's disease.

c) Notice changes in smell and other bodily functions: A reduced ability to smell or taste, constipation, and urinary problems may also be early signs of Parkinson's disease.

d) Keep track of the progression of symptoms: Parkinson's disease is a progressive condition, and symptoms tend to worsen over time. If you notice a gradual worsening of any of the above symptoms, it may be a red flag for Parkinson's.

It's important to remember that not everyone with Parkinson's will experience all of these symptoms, and the severity of symptoms may vary. It's always best to consult a healthcare professional for an accurate diagnosis if you suspect Parkinson's disease.
