A concussion involves a jolt or blow to the head that causes the brain to move rapidly back and forth, potentially causing injury to brain cells and disrupting the normal functioning of the brain. This injury can cause cognitive symptoms such as memory problems, difficulty concentrating, and slowed thinking. The severity of the injury may also affect the extent of these symptoms. Factors such as loss of consciousness, duration of unconsciousness, and whether there was bleeding or other damage can all affect the resulting cognitive problems.
