Parkinsonism: Causes, Symptoms, and Treatment Options

Parkinsonism is a term that refers to a group of neurological disorders that share some of the symptoms of Parkinson’s disease, such as tremors, stiffness, slowness of movement, and balance problems. Named after the British physician James Parkinson, who first described the condition in 1817, Parkinsonism encompasses a group of disorders that share similar clinical features. While it often brings to mind the more widely recognized Parkinson’s disease, there are several forms of Parkinsonism, each with its distinct features and underlying causes.

Types of Parkinsonism

Parkinsonism is categorized into three categories, namely Primary Parkinsonism, Secondary Parkinsonism, and Atypical Parkinsonism. We will discuss these types of Parkinsonism in their respective sections in detail.

Age of Onset

Parkinsonism can affect people of any age, but it is more common in older adults. The disease most commonly affects individuals after the age of 60. However, approximately 5 percent of patients affected by Parkinsonism, experience the signs and symptoms of the disease before the age of 40 years. This is called Juvenile Parkinsonism.

The pattern of disease in both cases is almost the same except for some variations such as disease progression, where juvenile Parkinsonism can be more aggressive than old age-onset Parkinsonism. People with Juvenile Parkinsonism report with higher degree of cognitive loss/psychiatric symptoms, while those with onset of disease at later stages of life present mainly with loss of motor functions.

Symptoms of Parkinsonism

The hallmark symptoms of Parkinsonism revolve around motor dysfunction and movement impairment. These symptoms can manifest gradually and worsen over time.

Motor Symptoms

1. Tremors: Involuntary shaking of the hands, legs, or other parts of the body, often referred to as “resting tremors” as they tend to occur when the affected individual is at rest.

2. Bradykinesia: Slowness of movement, making simple tasks such as buttoning a shirt or walking more challenging.

3. Muscle Rigidity: Stiffness in muscles, leading to reduced range of motion and sometimes pain.

4. Postural Instability: Difficulty in maintaining balance and posture, increasing the risk of falls.

5. Gait Disturbances: Altered walking pattern, characterized by shuffling steps and reduced arm swinging.

6. Speech and Swallowing Issues: Reduced facial expression, soft voice, and difficulties in swallowing.

7. Micrographia: Smaller and cramped handwriting.

Non-Motor Symptoms

Parkinsonism isn’t confined to motor symptoms alone. Non-motor symptoms can also significantly impact the individual’s quality of life. These can include:

Cognitive Changes: Memory difficulties, impaired reasoning, and a decline in cognitive functions are common in some forms of Parkinsonism.

Autonomic Dysfunction: This can lead to issues with blood pressure regulation, gastrointestinal problems, and urinary dysfunction.

Sleep Disturbances: Sleep disorders such as insomnia and REM sleep behavior disorder are frequently associated with parkinsonism.

Psychiatric Symptoms: Depression, anxiety, and even hallucinations can occur as part of the condition.

Causes of Parkinsonism

Parkinsonism can have a variety of underlying causes, including genetic factors, environmental triggers, and certain medical conditions. While Parkinson’s disease itself is characterized by the degeneration of dopamine-producing neurons in the brain, other forms of Parkinsonism can arise from different mechanisms.

Genetic Factors:

Some individuals carry specific genetic mutations that increase their susceptibility to Parkinson ‘s-like symptoms. These mutations can impact the functioning of key proteins and enzymes involved in neuronal health. The genetic factors can play a significant role in both early-onset and late-onset Parkinsonism.

Environmental Factors:

Exposure to certain toxins or chemicals, such as pesticides and industrial solvents, has been suggested as a potential risk factor for developing Parkinsonism.

Drug-Induced Parkinsonism:

Some medications, particularly those used to treat psychiatric disorders, can lead to Parkinsonism-like symptoms. These symptoms often improve once the medication is discontinued.

Vascular Parkinsonism:

Reduced blood flow to the brain, often due to multiple small strokes, can result in symptoms similar to Parkinsonism.

Diagnosis and Differential Diagnosis

Diagnosing Parkinsonism involves a thorough medical history review, physical examination, and often, a response to anti-parkinsonian medications. Physicians may also employ neuroimaging techniques like MRI and PET scans to rule out other conditions with similar symptoms. Differential diagnosis is crucial, as conditions like essential tremor, multiple system atrophy, and drug-induced parkinsonism can mimic Parkinson’s disease.

Management Strategies for Parkinsonism

While there is no cure for Parkinsonism, several strategies aim to alleviate its symptoms and improve the quality of life for affected individuals. These strategies often include:


Dopamine-replacement therapies, such as levodopa, help manage motor symptoms by replenishing dopamine levels in the brain. Other medications target specific symptoms like tremors and rigidity.

Physical Therapy:

Exercise programs, balance training, and stretching can help improve mobility and reduce muscle stiffness.

Occupational Therapy:

Occupational therapists assist individuals in adapting to daily tasks and suggest tools to make tasks easier.

Speech Therapy:

Speech therapists help address speech and swallowing difficulties, enhancing communication and preventing aspiration.

Surgical Interventions:

In cases resistant to medication, deep brain stimulation (DBS) surgery may be considered. This involves implanting electrodes in specific brain regions to regulate abnormal brain activity.

Lifestyle Modifications:

A balanced diet, regular exercise, and adequate sleep can contribute to overall well-being and symptom management.

Psychological Support:

Individuals with Parkinsonism often face emotional challenges. Counseling, support groups, and psychotherapy can help address depression, anxiety, and stress.

Through ongoing research and medical advancements, the hope for better treatments and improved quality of life for those with Parkinsonism remains strong. If you or a loved one are experiencing any of the aforementioned symptoms, seeking medical attention is advised for proper diagnosis and management.
