Secondary Injuries and Syndromes 

After a brain injury, the body can develop secondary (TBI induced) injuries and/or syndromes due to the bodies reaction to the brain injury. Mental illnesses already present will worsened. Additionally, dormant illnesses/syndromes carried in the patient's genetics may be "turn on." 

Depression

It can develop for several reasons: a chemical imbalance after the injury, dealing with chronic symptoms, loss of preTBI life, etc.  Let's face it, the aftermath of a brain injury is depressing and scary.

Fibromyalgia

Fibromyalgia is a disorder characterized by widespread musculoskeletal pain accompanied by fatigue, sleep, memory and mood issues. Researchers believe that fibromyalgia amplifies painful sensations by affecting the way your brain processes pain signals.

Symptoms of fibromyalgia include:

  • Widespread pain. The pain associated with fibromyalgia often is described as a constant dull ache that has lasted for at least three months. To be considered widespread, the pain must occur on both sides of your body and above and below your waist.

  • Fatigue. People with fibromyalgia often awaken tired, even though they report sleeping for long periods of time. Sleep is often disrupted by pain, and many patients with fibromyalgia have other sleep disorders, such as restless legs syndrome and sleep apnea.

  • Cognitive difficulties. A symptom commonly referred to as "fibro fog" impairs the ability to focus, pay attention and concentrate on mental tasks.
