What are the complications of a subdural hematoma?

A subdural hematoma can be very serious and can result in death or disability if not recognized and treated quickly. Possible complications include:
  • Brain herniation (severe pressure on the brain that causes coma or death)
  • Permanent brain damage
  • Persistent symptoms or seizures
If symptoms appear after a known head injury, contact a doctor right away. Early treatment of subdural hematoma can prevent problems and improve recovery. Symptoms include:
  • Headache
  • Weakness or numbness in arms, legs, or face
  • Poor balance or coordination
  • Change in behavior, emotions, or memory
  • Drowsiness, lethargy, or coma
  • Changes in vision
  • Trouble speaking, swallowing, or communicating
  • Nausea/vomiting
  • Seizures

In some cases, the pressure on the brain from a subdural hematoma can be serious enough to lead to coma or even death. Other possible complications may include:

  • Seizures.
  • Long-term problems with memory and concentration.
  • Persistent dizziness, anxiety, and headache.
  • Temporary or even permanent numbness, weakness, and speech problems.
