On the road to recovery from brain injury, discovering a separate and disabling syndrome

By Dr. Jonathan Fellus, MD Working with individuals with traumatic brain injury (TBI) every day, I see the debilitating effects and long-term struggles firsthand. TBIs are complicated and can cause a multitude of other neurological and medical issues, but with appropriate and individualized care, patients can recover and ease back into daily life—slowly but surely. TBI Defined According to the Brain Injury Association of America, 1.7 million people sustain a TBI each year. A TBI is caused by a significant force to the head or a penetrating head injury that disrupts normal brain functions. Diagnostically, the severity of a TBI can range from “mild” with a brief change in mental status or consciousness to “severe,” an extended period of unconsciousness or amnesia. However, the consequence of any given TBI depends on many different factors ranging from the individual's genetic susceptibility to the unique areas damaged relative to the person's particular pattern of pre-injury strengths and weaknesses. Effects of a TBI As we all know, the brain controls important functions we rely on daily, coordinating our body’s systems, such as breathing, heart rate, body temperature, and metabolism; thought processing; body movements; personality; behavior; and the senses, such as vision, hearing, taste, smell, and touch. When a brain injury occurs, the neurons and nerve tracts that carry messages through the brain can be affected, thereby disrupting and disabling these important daily functions. The effects of a TBI are dependent on where in the brain and how widespread the injury occurs. The brain is divided into main functional sections, called lobes, including the Frontal, Temporal, Parietal, and Occipital Lobes, along with the Cerebellum and the Brain Stem. Each has unique functions, so depending on which area of the brain is affected, a TBI can change the way a person thinks, acts, feels and moves the body. A TBI may alter other essential internal functions, such as blood pressure, hormonal, or bowel and bladder control. Depending on the severity of the injury, these changes can be temporary or permanent. Treatment It’s important to remember the effects of a TBI are complex and vary greatly from person to person, depending on the cause, location and severity. When treating a TBI, the goal is to resolve acute issues relating to basic functional loss, such as respiratory management, sleep/wake cycle, bowel/bladder incontinence, communication and mobility before addressing other secondary issues that may arise. Treating the initial chaos of TBI sequelae or consequences, reminds me of a kaleidoscope—trying to decipher the picture emerging from a complex array of fragmented, moving targets. As TBI patients evolve through the various stages of recovery, they become more active participants with regards to treatment, often engaging in goal setting with caregivers to enhance quality of life. With greater communication from the patients, clinicians can better detect less obvious facets of the disease and maximize potential for functional recovery. While the brain continues to heal, patients often revert to childlike tendencies and have to relearn how to resist certain impulses and maladaptive physical or interpersonal behaviors. On the flipside, with this increased participation during later stages of recovery also comes a greater sense of the difficulties that lie ahead. This is a classic time for patients to react impulsively and often inappropriately with an increased risk of depression and suicide. There is a dynamic interaction between cognition, mood and behavior that can be a struggle for patients, caregivers and the interdisciplinary treatment team. Therefore, it’s important for all parties—physical, occupational, speech/language and cognitive therapists, along with neuropsychology-- to work together to help mitigate the complex disability that follows TBI. Brain rehabilitation doctors coordinate these activities, setting priorities and goals while using medications to facilitate recovery or reduce medical and neurological complications that emerge or persist. A wife of one of my patients compares a TBI to the layers of an onion. As you peel away the different sections and treat each issue, there’s a greater hope of recovery and a sense of “normalcy.” Neurological Ramifications Although there are certainly physical components to the puzzle, it’s often the cognitive, behavioral and emotional repercussions that are the most incapacitating, preventing TBI patients from resuming roles in the community over the long term. As the dust settles and immediate medical or neurological issues are addressed, more subtle neurological problems may emerge as patients have a greater ability to discuss how they’re feeling. One such issue comes in the form of a distressing condition called pseudobulbar affect (PBA). Causes of PBA PBA is a neurological, not psychiatric, syndrome caused by a TBI and certain other underlying neurologic diseases, such as MS, ALS, Alzheimer’s or Parkinson’s disease and stroke. PBA occurs when the primary neurological condition damages the areas of the brain that control normal emotional expression. This disrupts brain signaling and causes 'short circuits’ in the form of unpredictable episodes of crying or laughing that can be frequent and severe, and may interfere with everyday life. These outbursts are often incongruent with the patient’s current emotional state, leaving them to laugh or cry when they don’t find things funny or sad. Due to the unpredictable nature of PBA, episodes often cause embarrassment for those living with the condition, particularly in social settings. These crying or laughing episodes are often so embarrassing they can interfere with routine activities or cause patients to avoid certain situations altogether. Moreover, PBA sufferers often acknowledge that they spend significant time and energy trying to hold back or simply control their emotions. Finally, PBA also has a negative impact on loved ones and caregivers as they struggle to adjust to these outbursts.

Suspecting and Diagnosing PBA Due to minimal awareness and knowledge of PBA in the medical community, PBA is often misdiagnosed as depression or part of the primary neurological disease—when in fact, it’s a separate, treatable condition. Nearly two million people may have PBA, but many go undiagnosed. It’s important for physicians to understand the differences between PBA and depression, so patients can receive proper treatment. With a greater understanding among doctors and patients, PBA can be diagnosed more accurately and treated appropriately. A patient suffering from PBA may show the following tell-tale signs:

  • Crying or laughing for no apparent reason

  • Laughs or cries at inappraproprite times; frequently smiles or grimaces

  • Experiences outbursts of crying and/or laughing that are exaggerated or not proportional to the situation

  • Can’t control their laughter or tears, even when they try to, often spending time and energy “holding back”

  • Socially isolates themselves out of frustration, fear and humiliation of having an episode in public

Coping with PBA In addition to talking with a physician, patients can keep track of their episodes in a diary to better understand what triggers PBA symptoms, employ appropriate coping techniques and help the doctor treat the condition appropriately. By taking a more active role in recording these emotional episodes, patients ensure better patient-doctor communication and a more accurate diagnosis. Here are some general tips to help cope with PBA episodes:

  • Be open about it. Let people know that you cannot always control your emotions.

  • Distract yourself. If you feel an episode coming on, try to focus on something unrelated.

  • Change your body position. Note the posture you take when having an episode. When you think you are about to cry or laugh, change your position.

  • Breathe. Inhale and exhale slowly until you are in control.

  • Relax. Release the tension in your forehead, shoulders, and other muscle groups that tense up during an emotional episode.

Treating PBA When PBA persists, interferes with daily activities or fails to respond to the behavioral techniques above, it may be time to seek medical treatment. In October 2010, the U.S. Food & Drug Administration approved the first and only medication to treat PBA called NUEDEXTA® (dextromethorphan hydrobromide and quinidine sulfate) 20mg/10mg capsules, which is thought to act on the areas of the brain responsible for emotional expression. NUEDEXTA is a combination of two well-characterized medicines and is clinically proven to help reduce or even eliminate unpredictable crying or laughing episodes associated with PBA. Individual results may vary, and it’s important that patients tell their doctor if their PBA episodes continue or they experience bothersome side effects. Patients should periodically reassess the need for treatment as PBA symptoms may sometimes improve on their own. NUEDEXTA is not approved to treat other types of emotional lability. I personally have prescribed NUEDEXTA to many of my TBI patients experiencing PBA symptoms and have seen gratifying results. Inspiring Patient Story I work with many TBI patients every day, but one in particular, Richard Anderson, has an inspiring story of recovery and triumph. Richard was at the Jersey shore on family vacation during the summer of 2004 when he was hit by a drunk driver as his family was walking back to their hotel. His wife, Rose, was in the line of fire, but Richard instinctively pulled her out of the way and took the brunt of the collision, leaving him with a TBI and other serious injuries. Richard’s recovery from his TBI has been a long, arduous journey. Severe physical injuries, coupled with a multitude of additional effects of the accident—like the inability to taste and smell— left Richard unable to continue his job as a New York City public servant and resume his parenting responsibilities for his two daughters. These tasks fell primarily to Rose, and she became the stabilizing anchor of the family. After determining his unpredictable emotional symptoms were separate from depression and anger, I diagnosed Richard with PBA. Richard’s TBI coupled with PBA has had a tremendous impact on the Anderson family dynamic. After his TBI and onset of PBA symptoms, he has had difficulty maintaining his pre-injury activities and social contacts. Since Richard started taking NUEDEXTA, his whole family has seen a dramatic decrease in his crying episodes. We were also able to reevaluate his overall treatment regimen for controlling his PBA outbursts. He is still under my care and strives daily to reach his maximum functional potential, one layer of the onion at a time.
