Parkinson’s Disease

Neurology

Parkinson’s disease is a chronic and progressive neurological disorder affecting movement control.

It is named after Dr James Parkinson, who first described the condition in 1817. The disease primarily affects a region of the brain called the substantia nigra. This plays a key role in the production of dopamine, a chemical messenger involved in the coordination of movement.

The characteristic symptoms of Parkinson’s disease are:

Tremor: Resting tremor, typically starting in one hand, is a common early symptom of Parkinson’s disease. The tremor is usually seen as a rhythmic back and forth movement.
Bradykinesia: This refers to slowness of movement and difficulty initiating and executing voluntary movements. It can lead to decreased dexterity, slurred speech and a general feeling of weakness.
Muscle Stiffness: Parkinson’s disease can cause stiffness and rigidity in the muscles, making it difficult to move properly.
Postural Imbalance: As the disease progresses, individuals with Parkinson’s may experience impaired balance and coordination, leading to a tendency to stoop, stumble or fall.

Other non-motor symptoms that may accompany Parkinson’s disease include cognitive changes such as memory and thinking difficulties, mood disorders such as depression and anxiety, sleep disturbances and autonomic dysfunction such as changes in blood pressure and digestion.

The exact cause of Parkinson’s disease is still not fully understood, but probably involves a combination of genetic and environmental factors. There is currently no cure for Parkinson’s, but various treatments are available to manage symptoms and improve quality of life. These treatments may include medications, physical therapy, occupational therapy, speech therapy and, in some cases, deep brain stimulation (DBS) surgery.

FAQ

What’s Parkinson’s disease?

Parkinson’s disease is a progressive neurological disorder that affects movement control. It is characterized by symptoms such as tremors, slowness of movement, muscle stiffness, and impaired balance.

What are Parkinson’s symptoms?

Motor Symptoms:
Tremor (resting tremor)
Bradykinesia (slowness of movement)
Rigidity (muscle stiffness)
Postural instability
Akinesia (difficulty initiating movements)
Non-Motor Symptoms:
Cognitive changes (memory, attention, and thinking difficulties)
Mood disorders (depression, anxiety, apathy)
Sleep disturbances (insomnia, vivid dreams, excessive daytime sleepiness)
Autonomic dysfunction (orthostatic hypotension, constipation, urinary problems)
Sensory symptoms (hyposmia, pain, tingling sensations)
Speech and swallowing difficulties

What worsens parkinsons disease?

Factors that can worsen Parkinson’s disease include inadequate medication management, high levels of stress, infections, lack of exercise, poor sleep, other health conditions, and the natural aging process.

Is Parkinson’s disease painful?

Parkinsons disease itself is not typically associated with pain as a primary symptom. However, some patients may experience pain or discomfort due to secondary factors or associated conditions. These may include muscle stiffness and rigidity, which can lead to muscle cramps or discomfort. In addition, some patient’s disease may develop musculoskeletal problems or experience joint stiffness, posture changes or pain related to falls.

Can Parkinson’s disease be cured?

There is currently no known cure for Parkinson’s disease. Parkinson’s is a chronic and progressive neurological disorder, meaning it worsens over time. However, several treatment options are available for individuals with Parkinsons disease that can help manage symptoms and improve quality of life.

Is Parkinson’s disease fatal?

Parkinson’s disease itself is not considered directly fatal. However, it is a progressive neurological disorder that can lead to complications over time. This can result in a shorter life expectancy. The progression and impact of Parkinson’s disease can vary between individuals, and the rate of progression also varies.

How Parkinson’s disease is diagnosed?

Parkinson’s disease is diagnosed based on a comprehensive assessment of medical history, clinical symptoms and neurological examination. There is no specific test for diagnosis and the process involves ruling out other possible causes. A neurologist or movement disorder specialist typically performs the assessment, which includes a detailed medical history, a neurological examination to assess motor function and sometimes additional tests such as brain imaging. Response to Parkinson’s medications may also be considered in the diagnosis.

Is Parkinson’s disease hereditary?

Most cases of Parkinson’s disease are sporadic and not directly inherited, but in about 5-10% of cases there is a genetic component. Some genetic mutations may increase the risk of developing Parkinson’s, but a family history does not guarantee the development of the disease.

What causes parkinsons disease?

The exact cause of Parkinsons disease is not fully understood, but is believed to involve a combination of genetic and environmental factors. Genetic mutations and exposure to certain environmental factors may contribute to the development of the disease.

What foods are high in dopamine for Parkinsons disease?

Foods that may support dopamine production and brain health include protein-rich foods (e.g., lean meats, poultry, fish, eggs), fruits and vegetables (especially those rich in antioxidants), nuts and seeds, dark chocolate, and green tea.
