What Happens in a Brain Haemorrhage?

A brain haemorrhage is a type of stroke which occurs when a weakened blood vessel ruptures, causing an internal bleeding in or around the brain. Around 10-15% of all strokes are hemorrhagic or caused due to internal bleeding. It is important to understand that when bleeding occurs within the brain itself, you may not experience a headache, as the brain cannot recognise the ongoing disturbance. However, the outer coverings of the brain are sensitive, and if bleeding occurs there, you will experience a sudden and severe headache.

Common Causes

  • Head Trauma– One of the most common causes of brain haemorrhage is a severe injury in the brain.
  • High blood pressure– Over a prolonged period, blood vessels in the brain start to weaken, which may cause the walls of the vessel to rupture.
  • Aneurysm– This is the weakening of a blood vessel wall that swells. It can burst and bleed into the brain, leading to a stroke.
  • Amyloid angiopathy- This is an abnormality of the blood vessel walls that sometimes occurs with aging and high blood pressure. It may cause many small, unnoticed bleeds before causing a large one.

Can People Recover ?

How well people respond to a haemorrhage depends on the size of the haemorrhage. In some cases patients may recover quickly however, in some cases it may lead to death despite quick medical treatment.

How can we avoid a haemorrhage ?

  • Treat high BP- Around 80% of the haemorrhages are caused due to high blood pressure, it is important to keep your blood pressure in check through diet, exercise and medications
  • Avoid Smoking
  • Stay away from drugs- cocaine is known to increase the risk of bleeding in the brain.
  • Drive carefully and wear your seat belt
  • Wear a helmet, when you are on a motorcycle
  • Coumadin (Warfarin)- If you’re taking this medicine, check with your doctor if your blood levels are in correct range.

Treatment Options

Medications 

  • Antihypertensive drugs- Lowers blood pressure.
  • Diuretic – Increases urine production to get rid of excess salt and water.

Clipping 

Clipping is a medical surgery in which surgeons place a clip to seal a bulge in an artery wall to keep it from bleeding.

Rehabilitation

Rehabilitation involves retraining the brain’s pathway to improve mental functioning after an injury. For example an injury caused due to a blow on the head ( concussion).
