Objective:
To investigate the risk factors for memory or emotional complaints in patients with complicated mild traumatic brain injury (mTBI).
Methods:
Retrospective analysis of medical records was conducted by physicians in a teaching hospital in Southern Taiwan, and complicated mTBI had been identified by means of computed tomography. Psychological complaints, including problems with memory and emotions, were collected by structured telephone interviews, 10-15 minutes long, and were held with subjects who agreed to participate in our study. Among 327 patients who were injured for more than two years, 190 agreed to join this study (mean age: 41.6 years; male: 60.5%; stably employed: 50.0%). We used demographic data and neurological factors to predict memory or emotional complaints without muscle power or response speed (MEMR) complaints.
Results:
Only the presence or absence of cerebral contusions predicted memory or emotional complaints without MEMR complaints in different employed status, and the odds ratio was 4.82-13.50 times higher for those with cerebral contusions than for those without.
Conclusions:
Cerebral contusions were the primary risk factor for MEMR complaints in chronic complicated mTBI. Early preventive psychological intervention might be necessary for patients with complicated mTBI and cerebral contusions.
Insights
Cerebral contusions are a key risk factor for memory and emotional issues following complicated mild traumatic brain injury (mTBI). Early psychological intervention is recommended for patients with mTBI and contusions.
Area of Science:
- Neuroscience
- Clinical Psychology
- Traumatology
Background:
- Mild traumatic brain injury (mTBI) can lead to persistent psychological complaints.
- Identifying risk factors for cognitive and emotional deficits post-mTBI is crucial for effective management.
- Complicated mTBI, often identified via CT scans, may present unique challenges.
Purpose of the Study:
- To identify risk factors associated with memory or emotional complaints in patients with complicated mild traumatic brain injury (mTBI).
- To specifically examine neurological and demographic predictors of these complaints.
- To inform targeted interventions for long-term mTBI recovery.
Main Methods:
- Retrospective analysis of medical records from a Southern Taiwan teaching hospital.
- Inclusion criteria: patients with complicated mTBI (CT-identified) injured over two years prior.
- Structured telephone interviews assessed memory, emotional, and neurological complaints (MEMR) in 190 participants.
Main Results:
- Cerebral contusions were the sole significant predictor of memory or emotional complaints (without motor/speed deficits).
- Patients with cerebral contusions had 4.82 to 13.50 times higher odds of reporting these complaints.
- Employment status did not alter the predictive power of cerebral contusions.
Conclusions:
- Cerebral contusions are a primary risk factor for memory and emotional complaints in chronic complicated mTBI.
- These findings highlight the need for early psychological support in affected individuals.
- Preventive psychological interventions may be beneficial for patients with complicated mTBI and cerebral contusions.

The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
