Symptoms of cavernoma

A cavernoma often doesn't cause symptoms, but when symptoms do occur they can include:

  • bleeding (haemorrhage)
  • fits (seizures)
  • Headaches
  • neurological problems, such as dizziness, slurred speech (dysarthria) , double vision ,balance problemsand tremor
  • weakness, numbness, tiredness, memory problems and difficulty concentrating
  • a type of stroke called a haemorrhagic stroke

The severity and duration of symptoms can vary depending on the type of cavernoma and where it's located.

Problems can occur if the cavernoma bleeds or presses on certain areas of the brain. The cells lining a cavernoma are often thinner than those that line normal blood vessels, which means they're prone to leaking blood.

In most cases, bleeding is small usually around half a teaspoonful of bloodand may not cause other symptoms.But severe haemorrhages can be life threatening and may lead to longlasting problems.

You should seek medical help as soon as possible if you experience any of the above symptoms for the first time.
