A permanent shunt drains fluid from the cyst into the abdomen, where it is reabsorbed harmlessly into the body.

Can arachnoid cysts cause memory loss?

Local ischaemia induced by compression due to an arachnoid cyst may cause memory dysfunction and behavioural disturbances. 3 Untreated, may cause permanent severe neurological damage due to progressive expansion of the cyst. A variety of neurosurgical procedures may be used to decompress the cyst.
