A traumatic brain injury (TBI) occurs when a sudden blow or jolt to the head disrupts normal brain function. The effects can be immediate or delayed, and symptoms range from mild to severe. Whether the injury results from a car crash or a fall, it’s important to recognize the warning signs as soon as possible.
Physical symptoms to look out for
Physical signs of a TBI can include persistent headaches, nausea, vomiting, dizziness, and fatigue. You might also notice blurred vision, trouble with balance, or sensitivity to light and sound. In more serious cases, a person may lose consciousness, even for just a few seconds. These symptoms may appear right away or develop over time.
Cognitive and emotional effects
TBIs often affect how you think, process information, and manage emotions. You may feel confused, forgetful, or have difficulty focusing. Conversations might become harder to follow, and your thoughts may feel slower than usual. Emotional changes like irritability, mood swings, or anxiety can also appear—even if they seem unrelated at first.
Sleep problems and delayed warning signs
Sleep disturbances are another common symptom. You may sleep more than normal, have trouble falling asleep, or feel drowsy throughout the day. Other delayed signs include behavioral changes, such as withdrawal from social activities or a lack of motivation. In children, a TBI can cause unusual fussiness, changes in eating habits, or increased need for attention.
Serious signs that require urgent care
If symptoms worsen or new ones appear, such as seizures, slurred speech, repeated vomiting, or one pupil appearing larger than the other, seek medical attention right away. These signs may indicate a more severe brain injury and need immediate evaluation.
Recognizing the signs of a TBI can help prevent lasting damage. Early attention and proper care are key to recovery and safety.
