Feeling depressed after a concussion deserves attention, whether the change appeared immediately or became noticeable during recovery. Low mood, irritability, poor sleep, difficulty concentrating and loss of interest can overlap. A clinician can assess those symptoms and consider other possible causes; a website cannot determine why one person feels this way.
The CDC lists emotional and sleep changes among possible symptoms of mild traumatic brain injury. Its recovery guidance also advises follow-up when symptoms persist or worsen after a return to ordinary activity. Tell the treating clinician about mood changes as well as headaches or dizziness, even if the emotional symptoms were not obvious at the first visit.
What a useful medical history shows
Describe when the mood change began, how it has changed, and what you notice in daily life. Sleep, medication, pain, work demands and stress after a crash can affect the picture. A prior history of depression does not make a new or worsened symptom irrelevant, but the medical record should distinguish what existed before the injury from what changed afterward. Ask the clinician what follow-up or referral is appropriate instead of trying to diagnose the cause yourself.
You do not need an elaborate symptom diary. A short dated note about sleep, mood, concentration and activities that became difficult can help you give the clinician an accurate history. Bring medication changes and earlier treatment records when available. For related recovery issues, see our articles on fatigue after a concussion and headache after a car crash.
When to get urgent help
A worsening headache, repeated vomiting, new confusion, seizure, weakness, slurred speech or difficulty waking can signal an emergency after head trauma. The CDC advises immediate emergency evaluation for these danger signs. For thoughts of suicide or an emotional crisis, call or text 988, the Suicide & Crisis Lifeline. Call 911 in a life-threatening situation. Those routes are listed by the National Institute of Mental Health. A legal consultation is no substitute for urgent medical or mental health care.
Why the change matters in an injury claim
In a claim arising from a crash, the question is whether reliable evidence connects the symptoms and their effects to the injury. Treatment records can show what was reported, when it was reported, what the clinician found, and how the condition affected work, school or ordinary activities. The insurer may examine earlier records or other possible explanations. Accurate descriptions and consistent follow-up are more useful than trying to make every bad day sound the same.
Louisiana’s general prescriptive period for delictual claims changed for injuries arising on or after July 1, 2024. Civil Code article 3493.1 generally provides two years from the day injury or damage is sustained; earlier incidents may be governed by a different period. Do not assume that a later diagnosis restarts a deadline. A lawyer should evaluate the incident date and claim type. Our Baton Rouge brain injury page explains the firm’s approach to medical and functional proof.
Once immediate health needs are addressed, you can discuss a crash-related claim with the firm at (225) 500-5000. The useful starting points are the crash date, the initial medical visit, later symptoms and any work or school changes.
