Introduction to Brain Aneurysm

• Brain aneurysm is an abnormal bulging and
  protruding of one of the arteries inside the
  brain.
• Its a medical term that is characterized by
  abnormal widening or ballooning of a blood vessel
  in the brain, which has weakened over time.
• Brain aneurysm mainly develops at the junctions
  of the large arteries present at the base of the
  brain, in a region called circle of wills.
• Brain aneurysm can be life threatening and one
  should seek immediate medical attention.

Causes of Brain Aneurysm

• Risk factors that doctors and researchers believe
  contribute to the formation of brain aneurysm
  include
• Smoking
• High blood pressure and hypertension
• Congenital resulting from inborn abnormality in
  artery wall
• Family history of brain aneurysm
• Other disorders such as Ehlers-Danlos Syndrome,
  Polycystic kidney diseases, Marfan Syndrome, and
  Fibromuscular Dysplasia (FMD)

Continue- Cause of Brain Aneurysm

• Presence of arteriovenous malformation (AVM)
• Drug use, particularly cocaine
• Infection
• Tumors
• High cholesterol
• Traumatic head injuries
• Gender, women compared with men have an increased
  incident of aneurysm at a ration of 32

Symptoms of Brain Aneurysm

• There are no particular symptoms however, some
  of the probable ones are given below
• Severe headaches
• Peripheral vision deficits
• Perceptual problems
• Thinking or processing problems
• Speech complications
• Short-term memory difficulty
• Sudden changes in behavior
• Decreased concentration

• Loss of balance and coordination
• Fatigue

Diagnosis of Brain Aneurysm

• Diagnosis of brain aneurysm generally includes
  the following tests
• Computed Tomography (CT) Scan To detect bleeding
  in the brain.
• Computed Tomography Angiogram (CTA) Scan To
  locate the actual site of the aneurysm.
• Magnetic Resonance Angiography (MRA) To obtain
  images and pictures of the blood vessels.
• Cerebral Angiogram It is an X-Ray test, employed
  to locate small (less than 5mm) aneurysm.

Treatment of Brain Aneurysm

• There are two main surgeries which are used to
  cure brain aneurysm
• Coil Embolisation 
• Surgical Clipping
• Coil embolisation It is a procedure in which a
  small tube is inserted into the affected artery.
  Tiny metal coils are then moved through the tube
  into the aneurysm, thereby easing pressure and
  reducing its probability to rupture. This
  procedure is less invasive and more effective
  than surgical clipping.

Continue- Treatment of Brain Aneurysm

• Surgical clipping It is another method, where a
  tiny metal clip is placed around the base of the
  aneurysm to isolate it from normal blood
  circulation. It also relieves the pressure and
  keeps it from rupturing. 
• A brain aneurysm can be life-threatening if left
  untreated for long. The main dangers are
  suffering from a stroke or in extreme cases,
  death, especially if it ruptures and bleeds.
  However, its survival rates can increase by
  immediate hospitalisation and early detection.
