Flat Affect and Brain Injury

Flat Affect and Brain Injury

My sister sustained a brain injury more than six months ago. She is making progress, but she is depressed, and often she seems to have no emotions. It’s like she’s a blank most of the time. The doctors mentioned something called “flat affect.” Can you explain to me what exactly this is and will it go away? Also, is this from the brain injury or from the depression?


“Flat affect” is a common symptom after a traumatic brain injury. Affect refers to our emotional expressiveness — the degree to which our facial expression and demeanor reflect what we are feeling. People with flat affect may not show the normal signs of emotion, may appear apathetic, may speak in a monotone, and may not change the expression of their emotions in response to varying situations as we expect them to. They may also appear nonresponsive to the emotions of others. In the brain, expression of affect occurs in the frontal lobe function, with specific localizations within the right hemisphere, cingulate cortex, limbic system, and in other areas that are involved in arousal.

For someone like your sister, flat affect may or may not occur in conjunction with deficits in her ability to actually feel different emotions and/or her ability to identify and label her emotions. A careful assessment by a neuropsychiatrist or neuropsychologist is often necessary to tease out just what the level of the person’s emotional experience is.

Flat affect can be a factor of both the depression (also a common symptom after TBI) and the brain injury itself. As the depression is treated, through therapy and/or medication, you may see some lifting of the flatness as your sister becomes more emotionally responsive. Also, recovery is still occurring at six months post injury, so you may see more improvement over time. For some people, however, flat affect can be permanent.

Depending on your sister’s level of awareness, intervention may involve teaching her to recognize what her level of emotional expressiveness is and how others may read it. She can then learn and practice varying emotional expressions to show how she is feeling and how she wants others to perceive her. As with any other cognitive function following brain injury, intervention includes a combination of psychoeducation, remedial training/rehabilitation, teaching of compensatory strategies, and family/friend participation. A cognitive rehabilitation specialist — a speech therapist or a neuropsychologist — can work with your sister and with those around her to help her better express some emotion nonverbally, a step toward ensuring improved acceptance and integration into social activities and closer interpersonal relationships.

I was hoping that the person with the brain injury who tried Brain State Technology could tell more info about it. My questions would be: what type of brain injury do you have, Mild TBI, Moderate or Severe? How exactly does this Brain State Technology work? and how much does it cost? I know this website is not for medical advice, but I would like to hear more about your experience with this technology. The website seamed vague and no prices were listed, which makes me skeptical. Thank you.

I had a brain injury from a car accident. I suffered from PTSD syndrome, flat affect, couldn\'t focus or concentrate for very long, brain fog, etc. What saved me was Brain State Technology.......in a few treatments I was much better. I was so much better I decided to do more and with each successive round improved in other areas. After watching others also do this I would suggest to anyone especially those suffering with brain injury or depression or PSTD. Good Luck....it turned my life around.

I truly admire your use of these medical terms. May I suggest that though you are educated, many of the folks that do visit and have questions are NOT privy to the words you use. People that have BIs sometimes do not have the wherewithall to figure out long wordy sentences. Your language and ideas have to be simple and very easy to understand. For example; My wife suffered a TBI in 1981 and all these years later she suffers extreme emotional stress. She also cannot remember 4 sets of a number or two. Sequencing is a very big problem. Her ability to stare, read, concentrate and memorize is not there. So, finally, I appreciate your work and your presence here on the web. I will be happier if you apply what I humbly shared with you. Bye now.
