Parkinson's disease is a brain condition that gets worse over time. It's primarily known for affecting movement, but it can also impact your senses, thinking, and mental health.

Here's a breakdown of what happens:

What Causes It?
Parkinson's disease is caused by the loss of nerve cells in a part of the brain called the substantia nigra. These nerve cells are responsible for producing a chemical messenger called dopamine. Dopamine is crucial for controlling and coordinating body movements. When dopamine levels drop, it leads to the movement problems associated with the disease.

The exact reason these nerve cells die is not fully understood, but most experts believe it's a combination of genetic and environmental factors. Some research suggests that abnormal clumps of a protein called alpha-synuclein, known as Lewy bodies, play a role in the death of these neurons.

What are the Symptoms?
Symptoms usually start gradually and get worse over time. They can be grouped into two main categories:

• Motor Symptoms (movement-related): These are collectively called parkinsonism and include:

  • Tremor: Involuntary shaking, often starting in a hand or fingers, even when the muscles are at rest. This can look like "pill-rolling" where the thumb and forefinger rub together.
  • Bradykinesia: Slowed movement, making everyday tasks difficult. This isn't actual muscle weakness, but rather problems with muscle control.
  • Rigidity: Stiff and inflexible muscles, which can cause pain and affect posture. This can be a constant stiffness (lead-pipe rigidity) or a jerky, stop-and-go stiffness (cogwheel rigidity).
  • Postural Instability: Difficulty maintaining balance, which can lead to falls. This often appears as a hunched-over stance and shuffling steps.

• Non-Motor Symptoms: These can appear at any stage of the disease, sometimes even years before movement problems:

  • Loss of sense of smell (anosmia).
  • Sleep problems, such as insomnia or acting out dreams.
  • Depression and anxiety.
  • Constipation.
  • Changes in blood pressure, leading to dizziness when standing up.
  • Fatigue and lack of energy.
  • Memory problems and difficulty thinking or focusing.
  • Speech changes, such as speaking softly or quickly, or in a monotone.
  • Pain.

Treatment
Currently, there is no cure for Parkinson's disease, but treatments focus on managing symptoms and improving quality of life.

• Medications:

  • Levodopa: This is the most common and effective medication. Nerve cells use levodopa to make dopamine, replenishing the brain's supply. It's often combined with other medications to make it more effective and reduce side effects.
  • Dopamine agonists: These medications mimic the effects of dopamine in the brain.
  • MAO-B inhibitors: These drugs slow down the breakdown of dopamine in the brain, making more dopamine available.

• Supportive Therapies:

  • Physical, occupational, and speech therapies can help with movement, balance, flexibility, and communication.
  • A healthy diet and exercise are also important for overall wellness.

• Surgery:

  • Deep Brain Stimulation (DBS): This may be recommended for severe motor symptoms when medications are no longer effective. It involves implanting electrodes in the brain that are connected to a device that sends mild electrical currents to control movement.

While Parkinson's disease can become increasingly difficult to manage as it progresses, many people respond well to treatment and can maintain a good quality of life. Life expectancy for those with Parkinson's is often near-normal.
