Clinical information
Postconcussion syndrome (also referred to as traumatic brain syndrome, nonpsychotic) is characterized by a group of symptoms that persist after the initial concussion or mild traumatic brain injury. These symptoms may meet the criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and may overlap with mild neurocognitive disorder, specific personality disorder, or other specified mental disorders.
Below are the common clinical features:
- Post-traumatic headache or associated post-traumatic headache, often throbbing and persistent
- Cognitive deficits, including trouble concentrating, short-term memory loss, and attention issues
- Sleep disturbance, insomnia, or altered sleep-wake cycles
- Increased sensitivity to light and noise
- Mood changes such as irritability, sadness, or mood swings
- Dizziness, vertigo, or balance issues
- Blurred or foggy vision
- Anxiety disorders, including panic attacks or generalized anxiety
- Depression or other mental and behavioural disorders
- Subjective physical complaints, such as fatigue or nausea, that are not explained by other conditions
These symptoms may arise in various combinations and intensities, often exacerbated by stress, overexertion, or lack of rest. The syndrome may appear following even a mild head injury that involved loss of consciousness, though it's also common in head trauma cases without loss of consciousness.
Additional clinical context
- Often seen in patients requiring hospital admission after head trauma
- May accompany postencephalitic syndrome or occur alongside neurodevelopmental disorders
- Can be found during follow-ups in emergency medicine or head trauma rehabilitation programs
- Classification falls under diseases classified elsewhere, warranting precise documentation and coding
- The Glasgow Coma Scale may be referenced during initial assessment
- Cases may also involve psychogenic disturbances, whether observed directly or inferred based on symptom patterns
This condition illustrates the importance of holistic evaluation—both physiological and psychological—especially when symptoms continue to interfere with daily life.
