  • Hydrocephalus is a serious brain condition with fluid buildup.
  • Researchers studied the usual idea about fluid absorption and problems.
  • They now say the brain may not absorb heartbeat pulses.
  • Heartbeat pulses can make fluid move and raise pressure.
  • A part of the brain normally smooths the heartbeat pulses.
  • Hydrocephalus can affect babies, adults, and older people.
  • Common problems include walking difficulty and memory loss.
  • Treatment is usually surgery to place a shunt from brain.
  • Shunts often fail, causing repeated operations and long care.
