What is parkinsonism?
11 December 2025
It is a nervous system disorder that causes slow movements, tremors, and rigidity, especially in the upper and lower extremities. It is mainly caused by the intake of certain drugs, exposure to toxic substances, brain injuries, or the presence of specific diseases.
The causes of Parkinsonism are different from Parkinson’s disease, although the symptoms are similar. Causes include:
- High doses of narcotics.
- Stroke (Cerebrovascular accident).
- Ataxias (lack of voluntary coordination).
- Multiple system atrophy.
- Brain damage from anesthetic drugs.
- Encephalitis.
- Wilson’s disease.
- Lewy body disease.
- Drugs used to treat mental conditions or nausea.
- Carbon monoxide poisoning.
- Poisoning with mercury and other chemicals.
- Brain injuries or tumors.
- Meningitis.
- Progressive supranuclear palsy.
- HIV/AIDS.
Signs and symptoms Parkinsonism

Diagnosis and treatment Parkinsonism
The specialist doctor will analyze your symptoms and clinical history, then perform a physical examination and a series of studies to help rule out other diseases and confirm the diagnosis, such as Magnetic Resonance Imaging (MRI) and Computed Tomography (CT scan).
The treatment will depend on the symptoms and the cause of the Parkinsonism, but it usually includes medications to help treat symptoms and control movements, as well as physical and occupational therapy.
At the Neurological Center, a group of highly trained and certified doctors in various neurological specialties are prepared to treat you with the quality and warmth that characterizes us.
