Signs of a Serious Brain Injury After an Accident You Should Never Ignore<\/h2>\n

Some warning signs always mean you need emergency care. These are: passing out, a headache that keeps getting worse, throwing up again and again, seizures, confusion, slurred speech, weak arms or legs, and pupils that are not the same size.<\/strong> Any one of these means you need emergency medical care right away.<\/p>\n

This guide follows the way a scared family really lives through a head injury. First, what to watch for right after<\/strong> the accident. Next, what can show up hours or days later<\/strong>. Finally, the red flags that mean call 911 now<\/strong>.<\/p>\n

It also covers something most guides skip. It shows how to spot a brain injury in a child. And it explains why an injured person often can’t see their own symptoms.<\/p>\n

Why a serious brain injury can be easy to miss<\/h2>\n

Serious brain injuries don’t always show up right away. After a crash, fall, or attack, a rush of adrenaline can hide the early signs. A person may feel “fine” for hours. Then they can get much worse as bleeding or swelling builds inside the skull.<\/p>\n

A traumatic brain injury (TBI) is damage to how the brain works. It happens when a blow, bump, or jolt to the head \u2014 or violent shaking \u2014 disrupts the brain. According to the Mayo Clinic<\/a>, you don’t need a visible cut, a bump, or even a loss of consciousness to have one.<\/p>\n

That’s why “walking away” from a wreck doesn’t mean the brain is fine. In the catastrophic-injury cases our attorneys handle, families often say the same thing. The injured person seemed okay at the scene. Then they got worse over the next day or two. Knowing the warning signs \u2014 and who is watching \u2014 can save a life.<\/p>\n

Mild versus serious: what the difference looks like<\/h2>\n

A concussion is the mildest kind of TBI. Moderate and severe TBIs can cause lasting or permanent damage. You can’t grade the injury yourself. But a few clues you can see point to a more serious problem:<\/p>\n
