Parkinson Disease

Parkinson disease is a neurological disorder that causes the loss of nerve cells and often leads to movement-related problems.

What is Parkinson Disease?

Parkinson disease is a condition that causes the gradual loss of dopamine-producing cells in the brain. Dopamine is a neurotransmitter that helps regulate body movements. The loss of cells can have negative effects on movement control.

What Are the Symptoms of Parkinson Disease?

• Tremor: Rhythmic shaking of the hands, arms, legs, or jaw
• Bradykinesia (Slow Movement): Slowing of movements and difficulty in daily activities
• Rigidity: Stiffening and inflexibility of muscles
• Posture Problems: Postural abnormalities and balance issues

How is Parkinson Diagnosed?

Diagnosis of Parkinson disease is usually made based on clinical symptoms and certain tests. A neurologist will evaluate symptoms like tremor and muscle stiffness during an examination.

What are the Management and Treatment Options for Parkinson?

• Medication: Levodopa and other antiparkinson medications are used to alleviate symptoms.
• Physical Therapy and Exercise: Physical therapy may be recommended to improve mobility and manage muscle stiffness.
• Speech and Swallowing Therapy: As the disease progresses, speech and swallowing issues may arise. Therapy can be suggested to manage these issues.
• Surgical Options: Surgical interventions like Deep Brain Stimulation (DBS) may be considered in certain cases.

Individuals living with Parkinson disease are managed with a multidisciplinary approach. Regular follow-ups, medication therapies, rehabilitation, and supportive treatments can alleviate the effects of the disease. Since Parkinson's progresses differently in each individual, treatments should be personalized. Therefore, it is important to consult a doctor when symptoms are observed or concerns arise. 

What Are the Stages of Parkinson Disease?

Parkinson disease is typically a slowly progressing, chronic condition that presents itself in different stages over time. The stages are classified based on the severity of symptoms and their impact on daily life. The most commonly used classification is the Hoehn and Yahr Staging System, which examines Parkinson disease in five stages:

• Stage 1: Symptoms are usually unilateral. For example, only one hand may show tremor. Daily life is minimally affected.
• Stage 2: Symptoms affect both sides of the body. Posture abnormalities and muscle rigidity increase.
• Stage 3: Balance problems begin. The individual can still be independent but has an increased risk of falls.
• Stage 4: The slowing of movements (bradykinesia) becomes evident. Moving without assistance becomes difficult.
• Stage 5: The individual may become wheelchair-bound and require full-time care.

Since the progression of Parkinson disease can vary among individuals, this staging method may produce different results for each patient. Thus, individual assessment is crucial because the pathway of Parkinson’s can change from person to person. 

Symptoms of Young-Onset Parkinson

Although often known as a disease of aging, Parkinson symptoms can also appear at a young age. Those diagnosed with Parkinson before the age of 50 are classified as having “Young-Onset Parkinson”. This condition accounts for approximately 10% of all Parkinson cases. Symptoms of Parkinson disease that may be observed at a young age include:

• Muscle cramps and pains
• Involuntary muscle movements (dystonia)
• Slower progression of the disease
• Increased sensitivity to medications
• Depression, anxiety, and sleep problems

Younger individuals with Parkinson’s may be more affected due to social and psychological impacts. Therefore, early diagnosis and psychosocial support are extremely important.

Is Parkinson Disease Genetic?

While the origin of Parkinson disease has not been fully elucidated, it is thought that both environmental factors and genetic factors interact. Most Parkinson cases are sporadic (not occurring in other family members), but a genetic predisposition is present in some cases.

Genetic factors may play a more prominent role in the early onset of Parkinson disease. Especially in cases seen at a young age, genetic factors could have a greater impact. Mutations in genes such as LRRK2, PARK7, PINK1, and SNCA have been associated with Parkinson. However, these mutations are rare.

Genetic predisposition might increase an individual's sensitivity to the disease, but it does not trigger the disease on its own. Together with environmental factors, the risk of developing Parkinson may increase. Regular neurological follow-ups are recommended for individuals with a family history.

The Impact of Slowing Movements on Daily Life

Slowing movements (bradykinesia) is one of the most noticeable symptoms of Parkinson disease. It can cause significant difficulties in daily life. Individuals may find it hard to start walking or complete a movement. Slowing can also be noticeable in hands, facial expressions, speech, and writing. Slowing of movements might lead to the following issues:

• Reduction in handwriting size (micrographia)
• Fixed facial expression (mask face)
• Difficulty with fine motor skills like tying shoelaces or using cutlery
• Sluggishness and lack of desire in daily life activities

Physical therapy, exercise programs, and some medications may help reduce the slowing of movements. Early intervention can significantly enhance the patient's quality of life.

How is Parkinson Treatment Planned?

Treatment of Parkinson is personalized based on the progression of the disease, patient's age, symptoms, and quality of life. This planning is performed by a multidisciplinary team and may include the following elements:

1. Medication

The most common medication used in Parkinson treatment is Levodopa. This medication increases dopamine levels in the brain. Other treatment options include:

• Dopamine agonists
• MAO-B inhibitors
• COMT inhibitors

Medications are usually used in combination, and dose adjustments may be needed over time.

2. Physical Rehabilitation

Physical therapy programs are important for reducing muscle rigidity and improving balance. A daily exercise routine can decrease the risk of falls and support independent mobility.

3. Speech and Swallowing Therapy

As Parkinson disease progresses, individuals' fluency in speech and swallowing reflex may decrease. Special therapies can enhance quality of life by managing these conditions.

4. Surgical Interventions

In advanced-stage Parkinson patients, if medications are inadequate, surgical methods like deep brain stimulation (DBS) can be employed. This involves placing electrodes in specific areas of the brain to regulate abnormal signal transmission.

Lifestyle and Supportive Treatments

Lifestyle changes are as important as treatment for individuals with Parkinson. Balanced nutrition, exercise, quality sleep, and stress management can slow disease progression. Moreover, psychological support is crucial for dealing with the psychological effects of the disease. Having accurate information about Parkinson for both patients and their relatives can facilitate treatment adherence and provide social support.

The Role of Nutrition in Parkinson Disease

In the management of Parkinson disease, diet is as important as medication. Appropriate nutrition preserves body health and can enhance the effectiveness of certain medications. Individuals using Levodopa should carefully plan their protein intake, as high-protein foods can reduce the absorption of this medication. Nutritional recommendations for Parkinson patients include:

• Foods rich in antioxidants: Foods containing vitamin C, vitamin E, and flavonoids can reduce cell damage.
• Fiber-rich foods: Constipation, a common issue in Parkinson patients, makes the consumption of vegetables, fruits, and whole grains essential.
• Adequate fluid intake: Water consumption prevents constipation and is necessary for general health.
• Calcium and Vitamin D: They are essential for bone health and provide support against the risk of falls.

The nutrition plan should be prepared with a dietitian according to individual needs. Attention should be given to ensure meal times don't coincide with medication schedules.

Parkinson and Psychological Support

Parkinson disease affects individuals not just physically but also mentally. Coping with a long-term condition can trigger emotional states such as depression and anxiety. Therefore, providing support becomes a vital part of the treatment process. Common psychological effects seen in Parkinson patients include:

• Depression: Dopamine deficiency affects mood as well as movements.
• Anxiety disorders: Concerns about uncertainty and the progression of the disease can lead to anxiety.
• Social isolation: Tremors and movement disorders may cause a person to isolate themselves from society.

To cope with these effects, it is recommended to:

• Seek support from a psychiatrist or psychologist
• Participate in group therapies or support groups
• Maintain strong communication with close environment
• Allocate time for hobbies and social activities

Mental health directly affects the quality of life of Parkinson patients. Therefore, attention should be given not only to the physical but also the emotional aspects of the disease.
