Brain Injuries: New Study Finds Fewer People Recover From Post-Concussive Syndrome

The April 2017 issue of the Journal of Neurotrauma reports on a new study about post-concussion syndrome.

The study followed 110 patients who had post-concussive syndrome symptoms for more than three months, and the findings were stunning.  Of those patients, only 27% made a full recovery.  Of the 27% who made a recovery, 67% made a recovery within the first year.  And no one who had symptoms over three years ever made a recovery.

For those groups that didn’t recover, the continuing symptoms (in order of frequency) were:

  • Headache
  • Difficulty concentrating
  • Fatigue
  • Dazed/don’t feel right/in a fog
  • Pressure in the head
  • Sensitivity to light
  • Difficulty remembering events
  • Neck pain
  • Sensitivity to noise
  • Depression/sadness
  • Insomnia/sleep disturbance
  • Irritability
  • Anxiety
  • Frustration
  • Feeling slowed down
  • Noise in the ears
  • Vision changes
  • Lightheadedness
  • Imbalance
  • More emotional
  • Dizziness
  • Nausea
  • Increased sensitivity to alcohol
  • Confusion
  • Personality changes
  • Vivid dreams
  • Numbness
  • Vertigo
  • Panic attacks
  • Disorientation
  • Stomach ache
  • Loss of appetite
  • Slurred speech
  • Seizures
  • Vomiting

These findings are significant to our brain injury cases.

Most insurance companies argue that brain injuries typically heal themselves and symptoms disappear after six months or a year. The insurance companies use that argument to reduce the value of the claim.

This study refutes that.  If a client has had symptoms lasting more than three months, then this study is evidence that the client will likely never make a full recovery.   Obviously, if an injury is permanent then the value of the case is higher.

The study is also interesting because it has a good list of symptoms of a brain injury.  It’s important for people to know these symptoms to help them recognize when they might have a brain injury.

Another interesting fact was the distribution of the symptoms.  Generally, post concussion syndrome has three classes of symptoms:

  1. Cognitive symptoms — affect your thinking
  2. Affective symptoms — affect your mood (depression, irritability, etc)
  3. Somatic symptoms — separate symptoms (headaches, light sensitivity, etc).

The study found that the persisting symptoms were quite evenly distributed between the three classes of symptoms.
