Other mTBI symptoms include changes in sleeping patterns and difficulty with reasoning, concentrating, and performing everyday activities.A concussion can result in changes in mood including crankiness, loss of interest in favorite activities or items, tearfulness, and displays of emotion that are inappropriate to the situation. Common symptoms in concussed children include restlessness, lethargy, and irritability. Mechanism
Forces
The brain is surrounded by cerebrospinal fluid, which protects it from light trauma. More severe impacts, or the forces associated with rapid acceleration, may not be absorbed by this cushion. Concussions, and other head-related injuries, occur when external forces acting on the head are transferred to the brain. Such forces can occur when the head is struck by an object or surface (a direct impact), or when the torso rapidly changes position (i.e. from a body check) and force is transmitted to the head (an indirect impact).Forces may cause linear, rotational, or angular movement of the brain or a combination of them. In rotational movement, the head turns around its center of gravity and in angular movement, it turns on an axis, not through its center of gravity. The amount of rotational force is thought to be the major component in concussion and its severity.
Stage 2: Light aerobic activity such as walking or stationary cycling
Stage 3: Sport-specific activities such as running drills and skating drills
Stage 4: Non-contact training drills (exercise, coordination, and cognitive load)
Stage 5: Full-contact practice (requires medical clearance)
Stage 6: Return to full-contact sport or high-risk activities (requires medical clearance)At each step, the person should not have worsening or new symptoms for at least 24 hours before progressing to the next. If symptoms worsen or new symptoms begin, athletes should drop back to the previous level for at least another 24 hours.Intercollegiate or professional athletes, are typically followed closely by team athletic trainers during this period but others may not have access to this level of health care and may be sent home with minimal monitoring. Medications
Medications may be prescribed to treat headaches, sleep problems and depression. Analgesics such as ibuprofen can be taken for headaches, but paracetamol (acetaminophen) is preferred to minimize the risk of intracranial hemorrhage. Concussed individuals are advised not to use alcohol or other drugs that have not been approved by a doctor as they can impede healing. Activation database-guided EEG biofeedback has been shown to return the memory abilities of the concussed individual to levels better than the control group.About one percent of people who receive treatment for mTBI need surgery for a brain injury.
