About this study

We aimed to conduct a prospective longitudinal interventionnal monocentric study to assess the ability of seven tesla MRI to detect diffuses axonal lesions in patients presenting a post concussional syndrom (PCS) at seven days about a mild traumatic brain injury (MTBI). Our first objective was to evaluate the diagnostic performance of seven tesla MRI runned at seven days after MTBI among patients presenting a PCS.

Read the detailed description

Among patients admitted in emergency care units in France for mild traumatic brain injury, 10 % will develop post concussionnal symptoms. The variability of the clinical presentation lead to a syndrome at the border of neurology, psychiatry and neuro-traumatology. Ninety per cent of these patients will have a favorable evolution in three to six months while ten per cent will have persistant symptoms : dizziness, headache, nausea, drowsiness, anxio-depressive symptoms, irritability, memory impairments, attentionnal disorders. This conduct to an additionnal medical and social cost (medical re-consultation in emergency services, pharmaceutical expenditure due to over medication, social recognition, deterioration of social and professionnal relationships …). The litterature data show the presence of diffuse axonal lesions (DAL) frequently observed in patients victims of MTBI. These lesions seemed to be correlate with the occurrence of post concussional symptoms. New brain imagery have lead to these discoveries but are not relevant in clinical routine (functionnal MRI, Diffusion Tensor Imaging, tractography). Computed Tomography is often normal and not able to detect these lesions. Standard MRI is not enough sensible for the detection of the DAL. Some autor shows alose that his sensibility decrease in time.

These observations and encouraging results lead us to initiate a prospective interventionnal, longitudinal, pilot study monocentric using seven tesla MRI to evaluate its input in the detection of diffuse axonal lesions among patients presenting post concussionnal symptoms after a mild traumatic brain injury at day seven after they are admitted to our emergency service.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Determine the diagnostic performance of 7 Tesla MRI performed of mild head trauma for the occurrence of post-concussion syndrome (PCS)

    appearance of diffuse axonal lesions

    Measured: Day 7

Secondary outcomes (8)
  1. Evaluate the S100b dosed at admission is correlated with the occurrence of post concussion syndrome after a mild head injury.

    Value of S100b dosed at admission

    Measured: Day 0

  2. Evaluate the S100b dosed at admission is correlated with diffuse axonal lesion

    appearance of diffuse axonal lesion and S100b dosed at admission

    Measured: Day 7, Month 6, Month 12

  3. Assess the quality of life of patients suffering for post-cocussion syndrome

    quality of life EQ-5D-5L questionary (score ranging from levels 1, 2, 3 (without problems) and levels 4,5 (with problems) and GOS-E scales (score ranging from 1.1 (good recovery) to 5 (death).

    Measured: Day 7, Month[6;12]

  4. Correlation the association between the alteration of the anisotropy fraction (AF) and post-concussion syndrome on the MRI diffusion tensor (DTI) sequence

    Focal alteration of AF data on a DTI sequence.

    Measured: Day 7

  5. Describe the diagnostic performance of the 7 T MRI and quality of life on the occurrence of a post-concussion syndrome

    Rivermead Post Concussion Scale, ranging from 0 to 4 ; 0 = minimal , 4 = severy problem with 16 items results 64 points maximals (cut-off>12)

    Measured: Month [3;6;12]

  6. Compare the performance obtained on cognitive functioning as a function of cognitive reserve

    Attentional Performance : Reaction times, correct, false responses and omissions = percentiles. 5 ≥ pathological. memory disorder : Verbal Learning Test : ≥ -1.65. pathological. bells test. Nb of total omission and a score of Left-Right omission are reported. Pathological > 6 or a left-right score > 2. Visual reproduction . immediate and delayed recall < 7 pathological. Times to name, to read colours. Total errors are also converted in standard notes.Verbal fluencies Nber of words beginning with the letters P,R,S in 1 min. for each letter are summed. The result is z-scored. Perceptual Reasoning index : Block design and Picture Completion. Sum of the standard notes = percentile rank. Verbal Comprehension index : Similarities and Information. Sum of the standard notes = percentile rank. Working Memory index : Arithmetic and Digit Span. Sum of the standard notes = percentile rank.Processing speed index : Code. The standard note = twice to obtain the percentile rank.

    Measured: Month 3

  7. Compare in patients the presence of anxio-depressive syndrome

    Beck scale (Beck Depression Inventory Scale). The score runs from 0 to 39. 0-3 : no depressed mood; 4-7 : light depressed mood; 8-15 : mild depressed mood; 16 and more : severe depressed mood.

    Measured: Month 3

  8. Correlation the association between the presence of a lesion on 7T MRI and the results of various neuropsychological tests.

    Attentional Performance : Reaction times, correct, false responses and omissions = percentiles. 5 ≥ pathological. memory disorder : Verbal Learning Test : ≥ -1.65. pathological. bells test. Nb of total omission and a score of Left-Right omission are reported. Pathological > 6 or a left-right score > 2. Visual reproduction . immediate and delayed recall < 7 pathological. Times to name, to read colours. Total errors are also converted in standard notes.Verbal fluencies Nber of words beginning with the letters P,R,S in 1 min. for each letter are summed. The result is z-scored. Perceptual Reasoning index : Block design and Picture Completion. Sum of the standard notes = percentile rank. Verbal Comprehension index : Similarities and Information. Sum of the standard notes = percentile rank. Working Memory index : Arithmetic and Digit Span. Sum of the standard notes = percentile rank.Processing speed index : Code. The standard note = twice to obtain the percentile rank.

    Measured: Month 12
