Posttraumatic cognitive symptoms

Discussion of post-traumatic cognitive symptoms













Not surprisingly, cognitive impairment is a common symptom after traumatic brain injury. The most commonly reported affected areas include areas of concentration, focus, executive functioning, memory, and processing speed, all centralized to frontal lobe circuits. Accordingly,  a majority of people suffering from a TBI complain of feeling “foggy” or “slow,” and in mild TBI a subtle decline in performance on cognitive testing can be seen after head injury. In a study observing the effects of prolonged cognitive outcome after a concussion in women, results showed a significant impairment of performance on a neuropsychological test of “processing speed associated with executive functions” often utilized in female soccer players (Ellemberg et al., 2007). Nonetheless, similar to other post-traumatic symptoms, full cognitive recovery occurs within 2-4 months of an injury. 

The treatment for TBI-related cognitive dysfunction is largely based upon accommodation of cognitive deficits and slowly returning to normal functioning. As individuals often struggle with focus and concentration,  returning to cognitively demanding activities such as work and school can be frustrating and delay eventual recovery.  Cognitive behavioral therapy is a structured approach to increasing understanding of deficits, offering accommodations to help with mental slowness, and teaching methods to improve cognitive functioning (Chung et al.,2013). Additionally, approaches such as mindfulness, use of memory aids, and relaxation activities have shown effectiveness in executive function rehabilitation (Pasini et al., 2014).

Additional to cognitive therapies, prescription medications have demonstrated improvement in impaired attention.  Stimulants work on the transmission of neurotransmitters between neurons, and improvements in attention and cognitive testing have been shown with the treatment of stimulants. A study using methylphenidate, a widely prescribed psychostimulant, showed improvement in accuracy and reaction time in traumatic brain injury patients in sustained attention tasks (Kim et al., 2011).

Treatment for post-traumatic cognitive disorder

  • Referral for cognitive behavioral therapy

  • Referral to Speech Therapy​​

  • Start medications:

    • Modafinil

    • Other stimulants

Mindfulness exercises 

Scientific studies have revealed that a variety of mindfulness exercises, including meditation, hypnosis, and yoga, can improve cognitive functioning. In a study tracking the improvement of cognition with mindfulness-based exercises, researchers observed improvements in general cognition in addition to improved memory, attention, executive function, and processing speed (Sevinc, 2021). 

At Los Angeles Brain Science Project, we have curated this document including mindfulness resources we find most effective in improving cognitive symptoms in traumatic brain injury patients.
