Brain lesion - Definition

Ask a question


A brain lesion defines damage to the cerebral nerve tissue. This can manifest in two different ways. The first involves an acquired brain lesion, when a patient undergoes trauma just after birth. The second represents a traumatic brain lesion that, as its name suggests, is caused by a blow to the head. The consequences of a brain lesion are therefore proportional to the severity of the trauma. Some symptoms, such as headaches, nausea, pain in the eyes, and mood disorders can help establish a diagnosis of brain lesion.
