POSTENCEPHALITIC PARKINSONISM Meaning and
Definition
-
Postencephalitic parkinsonism is a neurological disorder that is characterized by symptoms similar to those of Parkinson's disease. It is a condition that occurs after a viral infection or inflammation of the brain, most commonly caused by an epidemic encephalitis. This condition mainly affects the basal ganglia, a region of the brain that is responsible for controlling movement.
The main symptoms of postencephalitic parkinsonism include tremors or trembling, rigidity or stiffness in the muscles, bradykinesia or slowed movements, and difficulties with walking and balance. Patients may also experience muscle stiffness, difficulty swallowing, slurred speech, and a stooped posture. Additionally, they may have cognitive impairments such as memory loss, confusion, and sometimes, psychiatric symptoms.
Diagnosis of postencephalitic parkinsonism involves a thorough medical history and evaluation of symptoms. Medical imaging techniques such as MRI or CT scans may be used to assess the brain for any signs of inflammation or damage. Additionally, blood tests can be conducted to detect any infection or autoimmune response that may have triggered the condition.
Treatment options for postencephalitic parkinsonism are similar to those for Parkinson's disease itself. They primarily involve the use of medications to alleviate symptoms, such as dopamine agonists and levodopa, which help to increase dopamine levels in the brain. Physical therapy and rehabilitation may also be recommended to improve mobility and manage any muscle stiffness or weakness.
In summary, postencephalitic parkinsonism is a neurological condition that develops after an infection or inflammation of the brain. It is characterized by motor symptoms similar to Parkinson's disease, including tremors, rigidity, and bradykinesia. It can also cause cognitive impairments and psychiatric symptoms. Treatment involves medication and

Etymology of POSTENCEPHALITIC PARKINSONISM
The word "Postencephalitic Parkinsonism" can be broken down into three parts: "post-" meaning after, "encephalitic" meaning relating to encephalitis (inflammation of the brain), and "Parkinsonism" referring to the symptoms similar to those of Parkinson's disease.
The term itself was coined by the Austrian neurologist Constantin von Economo in the 1920s. It emerged as a result of an epidemic known as the "Sleeping Sickness" or "Encephalitis Lethargica" that occurred between 1917 and 1928.
During this epidemic, many individuals who had contracted encephalitis lethargica experienced significant neurological complications, including the development of Parkinson's disease-like symptoms. These symptoms included rigidity, bradykinesia (slowness of movement), tremors, and postural abnormalities.
