Mild Traumatic Brain Injury (MTBI) / Concussion
The patient has been diagnosed with a Mild Traumatic Brain Injury (MTBI) / Concussion. MTBI can be caused by either a direct blow to the head, face, neck or elsewhere on the body with an impulsive force transmitted to the head. MTBI typically results in the rapid onset of short-lived impairment of neurological function that may resolve spontaneously. In some cases, signs and symptoms evolve over a number of minutes to hours. Acute clinical signs and symptoms largely reflect a functional disturbance rather than a structural injury. As such, no abnormalities may be seen on standard structural neuroimaging (McCrory et al. 2017).
MTBI can result in a range of clinical signs and symptoms that may or may not involve loss of consciousness (LOC). In fact, only about 10% of concussions (MTBI) involve LOC. Resolution of the clinical and cognitive features typically follows a sequential course. In some cases symptoms may be prolonged (McCrory et al. 2017). When symptoms are prolonged greater than 30 days, the diagnosis should evolve to Persistent Concussive Symptoms (PCS).
The following represents the Diagnostic Criteria for evaluation of MTBI:
Mechanism of Injury
Any one of the following symptoms (Acute Concussion Evaluation [ACE], Geioia et al, 2006):
Physical: Headache, nausea, vomiting, balance problems, dizziness, visual problems, fatigue, sensitivity to light (photophobia), sensitivity to noise (phonophobia), and numbness/tingling.
Cognitive: Feeling mentally foggy, feeling slowed down, difficulty concentrating, and difficulty remembering.
Emotional: Irritability, sadness, more emotional, nervousness.
Sleep: Drowsiness, sleeping less than usual, sleeping more than usual, trouble falling asleep.
In this case, the patient was administered the Symptom Severity Score questionnaire. The Symptom Severity Score can be utilized as an outcome measure to track the patient's MTBI recovery. In this case, neurologic evaluation was performed in order to assess the need for neuroimaging to exclude a more severe brain injury (e.g., structural abnormality).
It should be noted that the following factors are predictors for prolonged recovery (McCrea et al. 2013; Rabanowitz et al. 2015):
Pre-existing Anxiety
Depression
High Symptoms Scores
Older Age
Female
Lack of Patient Education Following Injury
Missed Diagnosis by HCP
Therefore, in this case the patient was appropriately diagnosed and educated on MTBI's (McCrea et al. 2013).
