Hydrocephalus — commonly called “water on the brain” — is a condition in which cerebrospinal fluid builds up inside the brain’s ventricles, causing pressure that can affect brain development, movement, cognition and behaviour. It affects around 1 in every 500 children, making it one of the most common serious neurological conditions in childhood.
This section of Brain Care Path covers everything families need to understand about hydrocephalus: what causes it, how it is diagnosed, what a VP shunt or endoscopic third ventriculostomy (ETV) involves, and what life looks like after treatment. You will find articles written in plain language, medically reviewed by practising neurologists, covering topics from early warning signs in babies and toddlers to shunt revision surgery, long-term cognitive effects, school support, and daily life management.
Whether your child has just been diagnosed or has been living with hydrocephalus for years, the articles here are written by a parent who has walked this road — and reviewed by specialists who understand the clinical picture. Use the articles below to find answers, ask better questions at your next appointment, and feel less alone in the journey.
In the first weeks after diagnosis, I searched for a timeline constantly. I wanted someone to tell me: at six weeks, this will happen. At three months, this will have returned. At one year, this is what your son will look like. Nobody gave me the map.
TB of the brain explained – how tuberculous meningitis causes hydrocephalus, the early symptoms families miss, and what treatment involves.
He started banging his head against the cot rail. Not out of temper. Not playfully. With a rhythm and persistence that felt wrong — a two-year-old pressing his forehead into the bars again and again, unable to tell us what he was feeling.
The anaesthetist wore cartoon-print scrubs, and that small detail undid me more than the consent forms had. Someone had chosen those scrubs to make children less afraid, which meant children came through that room every single day — and somehow that thought steadied my hands.
VP shunt failure signs every parent should know – the 7 warning symptoms, what shunt failure looks like in infants, and exactly when to go to A&E.
When every moment matters — navigating seizures and hydrocephalus together. The first seizure happened three weeks after my son’s shunt surgery. I was in the room. He was lying on the bed and suddenly something changed — a stiffness, a tremor, his eyes rolling. It lasted less than a minute. It felt like an hour. We were back in hospital that same night. By the next morning, there was a second diagnosis to learn: epilepsy, secondary to the hydrocephalus. Two conditions. Two medications to understand. Two separate sets of warning signs to memorise. If this is where you are — managing both — this article is for you.
Twenty-eight days before a diagnosis that would change everything. The fever started, and we gave him paracetamol. That is always how it starts, is it not. Something manageable. Something every parent has done a hundred times. You check the temperature, you give the dose, you watch through the night. Two or three days later, the fever had not broken — it had climbed. We took him to the doctor. Throat infection, he said. He prescribed antibiotics. We went home and began the course, certain that within a few days we would be through the worst of it. The fever did not go down. We went back. The doctor increased the strength of the antibiotics.
Hydrocephalus in newborns – the early signs, how head growth is measured, how it is diagnosed by ultrasound, and what treatment involves.
For 28 days, my son had hydrocephalus and nobody caught it. He was seen by multiple doctors, admitted to hospital, treated for tuberculosis — and the real cause of his deterioration went undetected for nearly a month. He was three and a half years old. I am not writing this to criticise doctors. I am writing it because I wish someone had written it for me. Hydrocephalus — the buildup of cerebrospinal fluid inside the brain — is a serious neurological condition. It is also one that is frequently missed, delayed in diagnosis, or misattributed to other causes. Understanding why it gets missed — and knowing what signs to push for — could save your child months of suffering.
