'''Subdural Effusion''' is a medical condition that involves the accumulation of fluid between the [[dura mater]] and the [[arachnoid mater]], two of the three [[meninges]] that cover the brain and spinal cord. This condition is often associated with [[head trauma]], [[brain surgery]], [[meningitis]], or [[subdural hematoma]].

== Causes ==
Subdural effusion is typically caused by an inflammatory response to injury or infection. This response leads to an increase in the permeability of the blood vessels in the dura mater, allowing fluid to leak into the subdural space. The most common causes of subdural effusion include:

* [[Head trauma]]
* [[Brain surgery]]
* [[Meningitis]]
* [[Subdural hematoma]]

== Symptoms ==
The symptoms of subdural effusion can vary depending on the amount of fluid accumulation and the rate at which it accumulates. Common symptoms include:

* [[Headache]]
* [[Nausea]] and [[vomiting]]
* [[Seizures]]
* [[Neurological deficits]] such as weakness or numbness
* Changes in mental status, such as confusion or drowsiness

== Diagnosis ==
Subdural effusion is typically diagnosed through imaging studies such as a [[CT scan]] or [[MRI]]. These tests can show the presence of fluid in the subdural space. In some cases, a [[lumbar puncture]] may be performed to analyze the fluid for signs of infection or inflammation.

== Treatment ==
The treatment for subdural effusion depends on the underlying cause and the severity of the symptoms. In some cases, the condition may resolve on its own without treatment. In other cases, treatment may involve:

* Medications to reduce inflammation and swelling
* Surgery to drain the fluid
* Treatment of the underlying cause, such as antibiotics for an infection
