In older people there is the possibility that after a head injury, even of low intensity, there will be a small superficial bleeding inside the skull which over time creates a hematoma that progressively increases in volume, so that in the end it creates pressure effects on the brain. These are expressed by headaches, inability to concentrate and lethargy up to weakness in the movement of the limbs. Whether a Chronic Subdural Hematoma will be treated conservatively or surgically is a decision made after imaging tests, clinical examination and thorough follow-up.
