Types of Brain Lesions and Symptoms

the-brainAre you a victim of brain lesions but somehow not aware of what exactly does it mean and its symptoms and causes? Well, you have landed on the right page to learn more about this unsettled and confusing health problem.

What is brain lesion?

Brain lesion refers to the growth of abnormal tissue in or on the brain tissue. It is a disease or an area of injury within the brain. Lesions can be characterized according to whether or not they are cancerous or non-cancerous. For instance, malignant lesion is cancerous whereas benign lesion is non-cancerous.

What causes brain lesions?

Brain lesions can be caused by injury, exposed to chemicals, plaques, dead brain cell, and issue with the immune system, infection, malignancy, genetic, vascular, benign and trauma.

What are the different types of brain lesions?

Cerebral infarction:

A cerebral infarction or stroke refers to the death of brain cells or tissues due to lack of blood. Infarction has two further categories. These include:

Multiple sclerosis:

Under this condition, the immune system attacks and damages the nerve lining of the brain and towards the spinal cord. This type of lesions makes it difficult to send and receive messages properly between the brain and the body.

Cerebral palsy:

This occurs normally during pregnancy. The lesion directly affects the child's ability to move and also damages communication and other related skills.


These are area of infection, including inflamed and pus tissues. Although they are not common, however, they are highly life threatening. Brain abscesses usually occur in areas such as sinus, ear or occur after dental infection. They can also occur after a brain injury or surgery.


Tumours grow abnormally from normal tissues. They usually start in the brain and gradually spread elsewhere in the body. Tumours may either grow quickly or can remain stable.

Arteriovenous malformations:

This type occurs during the early development. Veins and arteries in the brain grow in a tangle and get connected with a structure called fistulae. These arteries are not as strong as normal arteries and the veins are enlarged because of the continuous blood flow straight from the arteries to the veins. These fragile vessels get damaged as blood leaks into the brain. The brain tissue on the contrary may not receive enough blood to function properly.


What are the symptoms of brain lesion?

Abnormal cell reflex in the eye that is caused either by retinoblastoma or cataracts

Bulging fontanelle where an area of the thin membrane and skin covering the brain expands and bulge outward due to outward abnormal pressure in the brain

  • Changes in personality, mood, mental ability, behaviour and concentration
  • Lack of appetite, feeling of nausea and vomiting
  • Skull sutures not closing properly due to brain tissue expansion or pressure
  • Headache, neck pain or stiffness.

How to treat brain lesions?

There are different methods to treat brain lesions. These include…

  • Use of antibiotics and steroids
  • Surgical treatment
  • Anti-clotting agent as plasminogen activator
  • Radiation and chemotherapy
  • Medication to treat immune system response.

As soon as you observe any such symptoms as mentioned above, immediately consult a doctor and get your problem diagnosed properly.
