Hydrocephalus, also called water on the brain, is the buildup of fluid in the cavities located deep within the brain. Over time, the fluid increases the size of the ventricles and puts pressure on the brain. It is normal for cerebrospinal fluid to flow through the brain and bathe the spinal column, but if there is too much pressure due to cerebrospinal fluid, it can damage brain tissues and impair brain function.

Risks & Causes

Hydrocephalus can occur at any age, but it is more frequent among infants and adults over the age of 60. It is caused by an imbalance between how much cerebrospinal fluid is produced and how much is absorbed into the bloodstream.

There are three reasons that there is excess cerebrospinal fluid in the brain ventricles:


Partial obstruction of the flow of cerebrospinal fluid is the most common problem that causes excess cerebrospinal fluid.

Poor absorption

There are sometimes problems with the mechanisms that enable blood vessels to absorb cerebrospinal fluid. This is usually related to the inflammation of brain tissues from either injury or disease.


In rare cases, cerebrospinal fluid is produced faster than it can be absorbed.


The symptoms of hydrocephalus depend on the age of onset.

  • Infants: Common signs of hydrocephalus in infants include an unusually large head, a rapid increase in head size, a bulging spot on the head, vomiting, sleepiness, irritability, poor feeding, seizures, eyes fixed downward, deficits in muscle tone and strength, poor growth and poor responsiveness to touch.
  • Toddlers and older children: Symptoms include headache, blurred or double vision, seizures, nausea, poor coordination, poor appetite, sleepiness, abnormal head enlargement, urinary incontinence, irritability, changes in personality, decline in school performance, and delays with previously acquired skills such as walking or talking.
  • Young and middle-aged adults: Symptoms include headache, lethargy, loss of coordination, loss of bladder control, impaired vision, and a decline in memory or concentration.
  • Older adults: Symptoms include bladder loss, memory loss, progressive loss of reasoning skills, difficulty walking, and poor coordination.

Medical Marijuana for Hydrocephalus

Medical marijuana is one of the most effective ways to treat the symptoms of hydrocephalus. It helps treat symptoms that are associated with the condition, such as sleep apnea, chronic seizures, manic attacks, bipolar outbursts, chronic or debilitating pain, frequent headaches and severe diarrhea.

Surgery is helpful to ease the pressure, but it doesn’t help with the long-lasting effects of the condition.
