What Are Parkinson Symptoms?
Parkinson disease (also known as Morbus Parkinson) is a chronic, progressive neurological disorder that primarily affects movement control. It is caused by the gradual loss of nerve cells in a region of the brain called the substantia nigra. These cells produce the neurotransmitter dopamine, which is essential for coordinating smooth and controlled movements. A deficiency of dopamine leads to the characteristic motor and non-motor symptoms of the disease.
Motor Symptoms
Motor symptoms are typically the most visible signs of Parkinson disease and are often what first prompts a medical evaluation:
- Tremor (shaking): A resting tremor, most commonly affecting the hands, fingers, or chin, is one of the hallmark signs. It typically occurs when the affected limb is at rest and has a rhythmic frequency of 4 to 6 Hz.
- Rigidity (muscle stiffness): Muscles become stiff and inflexible, often resulting in a characteristic stooped posture and limited range of motion. This stiffness can also cause pain.
- Bradykinesia (slowness of movement): Movements become slower and smaller over time. This manifests as a shuffling gait with small steps, reduced arm swing while walking, and smaller handwriting (micrographia).
- Postural instability (balance problems): In later stages, patients experience difficulty maintaining balance, significantly increasing the risk of falls.
Non-Motor Symptoms
Parkinson disease extends well beyond movement difficulties. Non-motor symptoms can precede the motor symptoms by years and profoundly affect quality of life:
- Sleep disturbances: REM sleep behavior disorder, in which individuals physically act out their dreams, is a common and early sign.
- Hyposmia (reduced sense of smell): A diminished ability to smell is one of the earliest warning signs, often appearing years before a formal diagnosis.
- Constipation: Slowed bowel movements are a frequent and early non-motor symptom.
- Depression and anxiety: Psychological changes are very common and are partly caused by the dopamine deficiency itself.
- Cognitive impairment: Concentration difficulties may develop over time, and Parkinson dementia can occur in advanced stages.
- Autonomic dysfunction: This includes orthostatic hypotension (a drop in blood pressure upon standing), excessive sweating, and bladder problems.
- Hypersalivation: Drooling can occur due to a reduced frequency of swallowing.
Early Warning Signs of Parkinson
Certain symptoms are recognized as potential early warning signs of Parkinson disease, often appearing before classic motor symptoms develop:
- Loss of smell without obvious cause
- Chronic constipation
- REM sleep behavior disorder
- Depressive mood or anxiety
- Shoulder pain or one-sided stiffness
Diagnosis
The diagnosis of Parkinson disease is primarily clinical, based on medical history and neurological examination. A neurologist looks for the presence of the cardinal symptoms: bradykinesia combined with rigidity, resting tremor, or postural instability. Imaging techniques such as DaTSCAN-SPECT may be used as a supportive diagnostic tool. A positive response to levodopa (the L-DOPA test) is also considered an important diagnostic criterion.
When to See a Doctor
You should consult a doctor promptly if you notice any of the following:
- New and persistent tremor in a hand or arm
- Progressive stiffness or slowness of movement
- Unexplained balance problems or frequent falls
- Noticeable changes in handwriting or voice
- A combination of several of the early warning signs listed above
Treatment
There is currently no cure for Parkinson disease. Treatment focuses on managing symptoms and maintaining quality of life. The main therapeutic approaches include:
- Medication: Levodopa (L-DOPA) is the most effective drug treatment and compensates for dopamine deficiency. Other medications include dopamine agonists, MAO-B inhibitors, and COMT inhibitors.
- Deep brain stimulation (DBS): In advanced disease, the surgical implantation of electrodes in specific brain regions can significantly reduce motor symptoms.
- Physiotherapy and occupational therapy: Targeted exercises help maintain mobility and independence for as long as possible.
- Speech therapy: Swallowing difficulties and speech problems can be addressed through speech and language therapy.
- Psychological support: Depression and cognitive symptoms are managed through psychotherapy and psychiatric care.
