Many people think a traumatic brain injury is obvious right away. In practice, residents often report that the most disruptive effects are cognitive and behavioral—headaches that intensify, dizziness that interferes with driving, memory gaps, irritability, trouble concentrating, and sleep disruption.
That’s why an “estimate” can feel frustrating. A number can’t measure whether your symptoms changed your ability to:
- keep up with work after commuting or training demands
- manage daily schedules on days when concentration drops
- drive safely when you’re dizzy or distracted
- participate in family responsibilities when mood and patience shift
In Mill Valley, where many people commute to jobs in the Bay Area and rely on predictable routines, insurers may try to minimize the functional impact unless your record tells a clear story.
