Second, the resulting subdural space that occurs from the separation of layers must remain uncompressed in order for CSF to accumulate in the subdural space, resulting in the hygroma. [1]
Verapamil, nimodipine, and other calcium channel blockers may help reduce the intensity and frequency of the headaches. [1] A clinician may recommend rest and the avoidance of activities or vasoactive drugs which trigger symptoms (see § Causes). [1] Analgesics and anticonvulsants can help manage pain and seizures, respectively. [1]

Increased pressure on the brainstem can result in dysfunction of the centers in the brain responsible for controlling respiratory and cardiac function. The most common signs are intractable headache, head tilt, and neck stiffness due to tonsillar impaction. The level of consciousness may decrease and also give rise to flaccid paralysis.
