Concussion
A concussion is a mild traumatic brain injury caused by a bump, blow, or jolt to the head — or by a whiplash-type force that snaps the head rapidly enough to make the brain move within the skull. In personal injury accidents, concussions arise from rear-end collisions, falls, sports impacts, and being struck by an object, and notably they can occur without any direct head contact and without loss of consciousness. The injury disrupts normal brain chemistry and cell function temporarily, producing headache, confusion, dizziness, light and noise sensitivity, and memory or concentration problems that may surface hours after the event. Because routine CT and MRI scans usually look normal in a single concussion, insurers commonly argue there is "no objective injury," even though the symptoms are genuinely disabling. The danger is amplified for anyone who returns to activity before fully recovering, since a second concussion during this window can cause severe, lasting harm. Unlike post-concussion syndrome, which describes symptoms persisting beyond the expected window, a concussion is the acute injury itself — but it is the gateway diagnosis on which any later cognitive claim is built, making prompt, accurate documentation essential.

Symptoms
The following symptoms are commonly reported by accident victims diagnosed with Concussion. Symptoms should be reported to your treating physician at every appointment to ensure they are documented in your medical record.
- 1Headache or a feeling of pressure in the head after impact
- 2Confusion, feeling dazed, or "not quite right" immediately after the event
- 3Dizziness, balance problems, or a brief loss of consciousness
- 4Sensitivity to light and noise
- 5Nausea, blurred vision, or ringing in the ears
- 6Difficulty concentrating and short-term memory gaps in the days after
Treatment & Recovery
Typical Treatment
Initial physical and cognitive rest, a medically supervised graded return to activity, hydration and headache management, vestibular therapy for dizziness, and close monitoring to catch any worsening that signals a more serious bleed.
Recovery Timeframe
Most concussions resolve within 7–21 days; a meaningful minority progress to post-concussion syndrome lasting months.
Get evaluated the same day even if you never lost consciousness — the absence of a knockout is the single most common reason concussions go undocumented and later disputed. Make sure the emergency or urgent-care record uses the words "concussion" or "mild traumatic brain injury," not merely "head bump," because the diagnosis on that first record anchors any later cognitive claim. Have someone note your confusion or memory gaps in the first hours, follow every return-to-activity instruction, and do not give a recorded statement minimizing your symptoms before the full 24–72 hour evolution has played out.
