Head injuries are dangerous. They can lead to permanent disability, mental impairment, and even death. To most people, head injuries are considered an acceptable risk when engaging in sports and other types of recreational activities. But there are steps you can take to lower the risk and protect yourself and your children.What Are Head Injuries?Head injuries are injuries to the scalp, skull, or brain caused by trauma. Concussions are the most common type of sports-related brain injury with an estimated 1.6 million to 3.8 million sports-related concussions a year. A concussion is a type of traumatic brain injury (TBI) that happens when the brain is jarred or shaken hard enough to bounce against the skull. This can happen when two athletes collide or when someone falls and hits his or her head. It can also result from being hit in the head with a piece of sporting equipment. In a sport such as soccer, even "heading" the ball can cause a concussion. A concussion causes an alteration of a person's mental status and can disrupt the normal functioning of the brain. Multiple concussions can have a long-lasting, cumulative life-changing effect.You don't have to be hit in the head to experience a concussion. An impact elsewhere on the body can create enough force to jar the brain. You also won't necessarily lose consciousness with a concussion. Concussions range from mild to severe. The effects may be apparent immediately, or they may not show up until hours or even days later.Other types of TBIs are a contusion, which is a bruise on the brain that can cause swelling, and a hematoma, which is bleeding in the brain that collects and forms a clot. A skull fracture is another type of head injury that can affect the brain. Sometimes with a fracture, pieces of bone can cut into the brain and cause bleeding and other types of injury.

Tuberculosis (TB) is a contagious, airborne disease that typically affects the lungs. TB is caused by a bacterium called Mycobacterium tuberculosis. If the infection is not treated quickly, the bacteria can travel through the bloodstream to infect other organs and tissues. Sometimes, the bacteria will travel to the meninges, which are the membranes surrounding the brain and spinal cord. Infected meninges can result in a life-threatening condition known as meningeal tuberculosis. Meningeal tuberculosis is also known as tubercular meningitis or TB meningitis.SymptomsAt first, symptoms of TB meningitis typically appear slowly. They become more severe over a period of weeks. During the early stages of the infection, symptoms can include:1. fatigue2. malaise3. low-grade fever
