G91.21: Secondary normal-pressure hydrocephalus
Cerebrospinal fluid has accumulated in your skull.
There are cavities with cerebrospinal fluid in the brain, around the brain and around the spinal cord. Among other things, the cerebrospinal fluid cushions the brain and spinal cord during knocks and also nourishes the brain cells.
The cerebrospinal fluid is produced in the cavities in the brain. The various cavities for cerebrospinal fluid are connected to one another. So the cerebrospinal fluid is able to flow through the different cavities in the brain to the space around the brain. The cerebrospinal fluid is reabsorbed in the cavity around the brain. Normally exactly as much cerebrospinal fluid is produced as is reabsorbed.
You have a condition that involves the cerebrospinal fluid accumulating in the cavities of the brain. The reason for this disorder may be, for example, a bleed, an inflammation, or an injury to the brain area.
With this condition, problems usually occur with the memory or the concentration. Typically, you also have walking difficulties. Your bladder may no longer be able to hold your urine.
