Autoimmune diseases, such as lupus and multiple sclerosis.Tumors that either start in the brain (primary tumors) or travel there (metastatic) via blood or lymphatic vessels.These can cause diseases like meningitis and encephalitis (both types of swelling (inflammation) of the brain). Infections, harmful germs or bacteria in the brain.Trauma to the brain, which can cause internal bleeding.Vascular conditions, such as stroke, high blood pressure, and cerebral artery aneurysms.The risk increases if someone else in the family has had the condition. The following factors put a person at greater risk to get brain lesions: Occipital lobe - found at the back of the brain, is primarily responsible for vision.īrain lesions can be caused by many different triggers. Parietal lobe - at the center of the brain, is where sensory information like heat, pressure and pain is received and interpreted. Temporal lobe - located on each side of the brain at ear level, is important for hearing, memory and speech. This area controls memory, intelligence, concentration, temper and personality. There are many parts to the brain, and each section has a specific role to play in the human body.įrontal lobe - the largest of the four lobes, is responsible for the body’s motor skills, such as voluntary movement, language, and intellectual and behavioral functions. The brain controls thoughts, memory, speech, movements of the limbs, and organ function. As lesions worsen with time, the symptoms become more noticeable. At first, brain lesions may not produce any symptoms. At other times, the lesions are present in a large part of the brain tissue. Sometimes lesions appear in a specific area of the brain. Lesions can be due to disease, trauma or a birth defect. Brain lesions are a type of damage to any part of brain.
