1. Causes of Parkinson’s Disease

Parkinson’s, also known as Parkinson’s disease, is a neurodegenerative disorder that affects the central nervous system. Although the exact causes of the disease are not fully understood, several factors contribute to its development:

  • Genetic factors: In about 10-15% of cases, genetic mutations play a role. Genes such as LRRK2, PARK7, PINK1, SNCA, and PRKN are associated with Parkinson’s. These genetic forms tend to occur more frequently in younger patients.
    Environmental factors: Pesticides, herbicides, and certain industrial chemicals seem to increase the risk of Parkinson’s. People living in rural areas or working in agriculture may be more affected.
  • Age: Age is the greatest risk factor. The disease typically occurs after the age of 60. As people age, dopaminergic neurons lose their function, leading to Parkinson’s symptoms.
  • Loss of dopaminergic neurons: A key feature of the disease is the loss of nerve cells in the substantia nigra, a part of the brain that produces dopamine. The lack of dopamine leads to the motor symptoms of Parkinson’s.

2. Demographic Distribution

Millions of people worldwide suffer from Parkinson’s. The prevalence is about 1-2% of people over the age of 60. In Germany, around 300,000 people are affected. Men have about a 1.5 times higher risk of developing Parkinson’s than women. Geographically, there are differences, and people in rural areas with higher exposure to pesticides have a slightly increased risk.

3. Symptoms

The symptoms of Parkinson’s can be divided into motor and non-motor categories:

  • Motor symptoms:
    • Tremor: Often begins with tremors in one hand and occurs mainly at rest
    • Bradykinesia (slowness of movement): Patients show a gradual slowing of movements, making everyday activities more difficult.
    • Rigidity: Muscles become stiff, causing pain and limited mobility.
    • Postural instability: Patients easily lose balance and are at an increased risk of falling.
  • Non-motor symptoms:
    • Depression and anxiety: Many patients develop emotional disorders.
    • Cognitive impairments: Some patients develop dementia over time.
    • Sleep disturbances: Insomnia and restless sleep are common
    • Autonomic dysfunctions: These include problems like constipation, urinary incontinence, or low blood pressure.

4. Course of the Disease

Parkinson’s disease is chronic and progressive. The course can be divided into four stages:

  1. Early stage: Mild motor symptoms, often on one side of the body. Patients are largely independent in daily life.
  2. Middle stage: Symptoms affect both sides of the body. Movements slow down significantly, and balance worsens.
  3. Late stage: Motor symptoms dominate, leading to falls and movement limitations.
  4. Advanced stage: Patients often develop cognitive impairments and require intensive care.

5. Treatment Options

There is no cure for Parkinson’s, but several treatment approaches aim to alleviate symptoms and improve quality of life:

  • Pharmacological therapy:
    • L-Dopa (Levodopa): It is considered the most effective treatment and is converted into dopamine in the brain.
    • Dopamine agonists: These mimic the effect of dopamine in the brain.
    • MAO-B inhibitors and COMT inhibitors: These medications extend the effect of dopamine or L-Dopa.
  • Surgical interventions:
    • Deep brain stimulation (DBS): Electrical impulses are delivered through implanted electrodes to specific areas of the brain to alleviate movement disorders.
  • Non-pharmacological approaches:
    • Physiotherapy
    • Occupational therapy
    • Speech therapy

Assistive devices and aids for Parkinson’s patients

Parkinson’s patients can benefit from various assistive devices to maintain their independence and facilitate daily tasks.

  • Mobility aids:
    • Walking sticks and walkers provide stability and reduce the risk of falls.
    • Non-slip shoe soles or anti-slip mats on the floor improve safety in the home.
  • Daily living aids:
    • Ergonomic cutlery with thick handles makes eating easier.
    • Button aids and dressing hooks support dressing, especially when fine motor skills are limited.
  • Communication and reminder devices:
    • Voice amplifiers help with speech problems.
    • Digital reminder devices remind patients to take their medication or attend appointments.
  • Safety aids:
    • Grab bars in the bathroom and raised toilet seats improve safety and accessibility.
    • Fall detectors can automatically call for help in an emergency.
  • Home environment adjustments:
    • Height-adjustable beds make it easier to get up.
    • Remote-controlled light switches and doors help when movement is limited.

Physiotherapy for Parkinson’s

Physiotherapy is an important pillar in the treatment of Parkinson’s as it can help improve motor skills, stabilize balance, and positively influence the course of the disease.

Importance of physiotherapy:

  • Slowing physical deterioration: Regular physiotherapy can help maintain mobility and slow the progression of the disease.
  • Improving quality of life: It promotes well-being, reduces pain, and helps maintain independence.
  • Reducing the risk of falls: Specific exercises aim to improve balance and gait.

Physiotherapy techniques:

  • Gait and balance training: Exercises such as walking on visual markers help improve gait and reduce the risk of falls.
  • Strength and flexibility training: Training muscle strength and joint flexibility is crucial to maintaining mobility.
  • Postural exercises: Targeted stretching and movements promote an upright posture to correct the typical stooped posture of Parkinson’s patients.
  • Breathing therapy: Breathing exercises help maintain lung capacity, especially in advanced stages.

Exercises for Parkinson’s patients:

  • Balance exercise on one leg:
    • Stand on one leg and switch after 30 seconds.
    • This improves balance.
  • Arm circles while seated:
    • Make slow circles with your arms to improve shoulder mobility.
    • Circle backward to activate the extensor chain and promote upright posture.
  • Step training with visual aids:
    • Walk over colored markers on the floor to train step coordination.
    • This exercises balance, gait pattern, and stride length.
    • Often, patients find it easier to walk evenly when they also receive an auditory stimulus, such as a metronome in step rhythm.
  • Wall push-ups:
    • Stand against the wall and slowly push yourself away to strengthen the arm muscles.
    • Perform this exercise either continuously or with holding moments.
  • Hip bridge:
    • While lying down, raise the pelvis and hold it to strengthen the back and leg muscles.

In conclusion, the combination of pharmacological therapy, physiotherapeutic measures, and appropriate assistive devices plays a central role in the treatment of Parkinson’s. Physiotherapy and the right aids help patients maintain their independence longer and improve their quality of life.
