8A00.3/VI Functional parkinsonism



Functional parkinsonism is a condition characterized by a range of symptoms that mimic those of Parkinson’s disease but are not caused by any identifiable physical or neurological disorder. It is believed to be caused by psychological factors such as stress, anxiety, depression, or trauma.


To diagnose functional parkinsonism, a physician will perform a physical examination, review the patient’s medical history, and order tests to rule out other conditions that may be causing the symptoms. They may also refer the patient to a neurologist or psychiatrist for further evaluation.

Differential diagnosis

Differential diagnosis of functional parkinsonism includes Parkinson’s disease, vascular parkinsonism, essential tremor, multiple system atrophy, progressive supranuclear palsy, and other movement disorders.


Treatment for functional parkinsonism is focused on managing the underlying psychological issues and may include medications, counseling, physical therapy, and lifestyle changes.


The prognosis for functional parkinsonism is typically good, as most cases can be managed with proper care. However, it is important to note that the underlying psychological issues must be addressed in order to improve the patient’s long-term prognosis.
