G91.3: Post-traumatic hydrocephalus, unspecified
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.
Due to an injury, your cerebrospinal fluid does not drain or get reabsorbed properly. As a result, the cerebrospinal fluid is increasingly accumulating in the cavities in the brain.
If a lot of cerebrospinal fluid collects in the skull, the pressure in the skull can increase. You may then get headaches and nausea, for example. If cerebrospinal fluid accumulates over a long period of time, other symptoms may occur. Walking may then be more difficult. You may also have problems with your memory or concentration. Your bladder may no longer be able to hold your urine.
