Lesions on the brain can be described as abnormal structural change in the tissues of the brain. It can be confined to just one area or it could be present in more than one areas. Even the size of the lesions can vary from small to large in every individual cases. In some cases, this condition can be harmless, while in some others, it can be a life-threatening condition.

Causes of brain lesions

  • Brain lesion is mostly formed when the tissues of the brain are damaged by some infection or injury or harmful chemical exposure.
  • A traumatic injury to the skull, stroke, multiple sclerosis, Alzheimer's disease, etc., can cause extensive damage to these tissues.
  • The infections in other parts, like the sinus or the ear, caused due to abscesses, and infectious diseases, like encephalitis can have this kind of effect as well.
  • Abnormal growth of clusters of veins, also known as arteriovenous malformation affect the normal blood supply to the tissues, and this condition may arise.
  • In children, it is supposed to be found due to a congenital abnormality called hydrocephalus.
  • Cancer of this organ or the growth of a benign tumour in this part can be responsible for this kind of complications. In many of the cases, the exact cause cannot be identified.

Symptoms of brain lesions

The symptoms of brain lesions depend on the size, location, and underlying health condition of the patients. Some patients even do not show any symptoms at all, and the disorder is discovered by chance. Some commonly-observed signs are:
  • Headache
  • Neck pain
  • Dizziness
  • Mental confusion
  • Seizures
  • Loss of memory
  • Vision changes
  • Sudden change in behaviour
  • Nausea
  • Vomiting
  • Loss of appetite
  • Fever

Diagnosis and treatment of brain lesions

MRI and CT scan are the two laboratory tests that help in the diagnosis of brain lesions. MRI images show the condition as dark or light spots that look quite different from the other normal tissues. The treatment is based upon the causes and symptoms. If there are no symptoms, then the neurologists prefer to keep a close watch on the size and location of the lesions with the help of regular checkups. In other cases, the main aim of the treatment is to get rid of the symptoms and improve the quality of life of the concerned patient.

If it is the result of some infections, then antibiotics are prescribed to control them. Other medicines are also administered to improve the response of the immune system and provide relief from the symptoms. When some malignant tissues are detected, then they are destroyed with the help of chemotherapy or radiation therapy. Depending on the size and location of the lesion and the health condition of the patient, surgical options may be availed for their removal. In many cases where medicines fail to show any results and surgery is not possible, some alternative methods of treatment, like physical therapy has proved to be beneficial in keeping the symptoms in check.

There are so many different possible causes that can lead to this disorder that its diagnosis and the treatment become slightly difficult. However, if anyone is diagnosed with it, there is no need to panic immediately. Discuss all your doubts with your neurologists and provide them with details about the medical history of the patient. This will help them to determine the best possible treatment. They will also give the right guidance on how to cope up with this problem.
