Parkinson's disease is a progressive neurological condition that primarily affects body movements. It occurs when there is a reduction in the production of dopamine, a substance essential for controlling movements in the brain.
🧠 What is Parkinson's disease?
Parkinson's disease does not appear suddenly. It develops slowly over time, and the first signs can be subtle, often mistaken for normal changes associated with ageing.
⚠️ Main signs and symptoms
The most common symptoms include:
-
Tremor at rest: usually starts in one of the hands, even when the person is still
-
Slowness of movement (bradykinesia): simple tasks take longer to complete
-
Muscle rigidity: sensation of a "stiff" or locked body
-
Changes in gait: short, shuffling steps, with difficulty initiating movement
-
Stooped posture
-
Decreased facial expression
In addition to motor symptoms, less well-known signs may also appear, such as:
-
Sleep disturbances
-
Constipation
-
Decreased sense of smell
-
Mood changes, such as anxiety or depression
⏱️ What to do when noticing the first signs?
Early identification makes a difference in disease control and quality of life. If you or someone close to you experiences suggestive symptoms:
- Seek medical evaluation
The diagnosis is clinical, made by a doctor, preferably a neurologist, based on medical history and physical examination.
- Avoid self-diagnosis
Not every tremor is Parkinson's. There are other causes, such as essential tremor or medication side effects.
- Start treatment as soon as possible, if confirmed
Although there is no cure, there are effective treatments that help control symptoms and maintain independence for longer.
- Adopt habits that help with control
Regular physical activity, physiotherapy, multidisciplinary follow-up and a good sleep routine are part of care.
- Observe the progression
Progressive changes should be monitored closely for treatment adjustments.
💬 Important message
Parkinson's disease does not mean immediate loss of independence. With early diagnosis, appropriate treatment and regular follow-up, many people maintain an active and good quality of life for many years.
