Defining brain injury has not been consistent in the medical research because of the complexity of the brain physiology. Improvements in technology has helped improve understanding of the brain but there still remain significant unknowns. Science journalist Carl Zimmer describes the brain as:

Nobel Laureate Eric Kandel described the human brain as “the most complex organ in the universe.” Damage to this vital organ can cause significant limitations to a person’s ability to process the activities of daily living and function both mentally and physically. Traumatic brain injury (TBI) happens suddenly but can leave a lifetime of permanent disabilities.

Medical research has not successfully discovered curative interventions to repair the brain to pre-injured status. The lack of proven effective treatments for restoring impairments means focus for interventions is on treating the symptoms associated with the multiply traumatic changes associated with brain injuries. This void in medical treatments indicates the need for psychosocial support for the TBI survivor, the spouse/partner, and family members. The main focus of therapy is 1) to help facilitate adaptation to a changed life, 2) to facilitate a quality of living with limited abilities, and 3) to create a collaborative new reality of well-being.

Impact on Family Dynamics

Traumatic brain injury does not happen in a vacuum. It is a chronic health issue that affects the entire family. Murray Bowen’s family systems theory explains how traumatic changes to one member of the family cascades throughout the family system. In nature, this is like throwing a pebble into a pond and observing how the water ripples throw out the pond. When one family member suffers traumatic changes, the stress is felt throughout the family system. The established patterns and roles are altered, changing the entire family dynamics. The heighten changes are a major stressor and cause a negative shift in the family’s well-being.

Family members are often described as the “neglected victims” of TBI. Many marriages end in divorce after brain injuries. The loss of an intact family causes further losses for the survivor. The difficulty learning to understand and cope with the monumental changes post injury are some of the reasons there is a need to conduct therapy from a family perspective. The therapeutic process needs to address loss, grief, and adaptation to creating a new life. Maintaining and developing socializations skills as well as a strong support system of family, friends, and a spiritual leader are helpful to the healing process.

‘An Invisible Disease’

There are many challenges to traumatic brain injury that sets it apart from other chronic illnesses. First, it has been described as an “invisible disease” and a “silent epidemic.” It is estimated that 1.7 million people are diagnosed each year. However, these numbers are considered an underestimate because of the lack of visible damages and the subtleties of impairments. The extent of cognitive deficits may not be apparent until much later. The insidious nature of the impairments means family members and professionals may overestimate the abilities of the survivor.

However, trauma to the brain frequently causes pervasive cognitive dysfunction and variety of personality changes, such as impulsivity, anger, fatigue, irritability, unpredictability, and depression. Lack of critical thinking, impaired social perceptiveness, and lack of empathy are also considered hindrances for the lack of awareness the survivor has about his or her own impairments and the decrease in motivation to adapt to a new reality. These problematic issues have a negative impact on martial/couple relationship, family dynamics, and relationships in general. Yet, the research indicates that a meaningful and supportive relationship can contribute to the TBI survivor’s healing from the psychological trauma.

Including Partners and Family Members

The recommended plan of care for the injured person includes psychosocial support for the caregiver, spouse, and family members. The North American Brain Injury Society (NABIS) reports a need for more effective incorporation of family support based on the last decades of research. Marriage and family research has shown that maintaining strong and supportive relationships are integral to helping the survivor cope with challenging changes, as well as for the spouse and family members to adapt to living with a new person.

Traumatic brain injury (TBI) represents a uniquely challenging medical condition. Repair of the physical, emotional, and cognitive damage is a long and often grueling process. In the wake of brain injury, patients often experience amnesia, altered consciousness, and profound confusion. Many of these symptoms mirror the psychotic states of schizophrenia; however, the root causes of these symptoms are, of course, quite distinct. Still, it’s not an uncommon practice for attending physicians to prescribe antipsychotic drugs such as Haldol (haloperidol) for TBI patients who exhibit aggression or restlessness. This practice is not without controversy, as several studies have shown that psychotropic medications, especially the typical antipsychotic drugs, may slow recovery from brain injury. A study published in Life Sciences adds even more compelling data to the argument against antipsychotic drugs for patients with TBI.

In a study of brain recovery rates under different conditions, a small group of rats were subjected to a controlled brain injury. The control group was anesthetized but no surgery was performed. The rats were further divided into three distinct groups. One group received a regular dose of Haldol, another received Risperdal (risperidone, an atypical antipsychotic), and a third group received neither drug. All the rats were given daily assessments of motor skills, reflexes, and cognitive functioning. Because antipsychotic drugs have a sedative effect, the drugs were only administered after each day’s performance testing. This is an important distinction because previous studies often gave drugs before testing, potentially skewing the results. Researchers sought to uncover any ill effects from these medications independent of sedation.

Although the sample size of this particular study was small, the results were quite significant. Regardless of whether the rats were given Haldol or Risperdal, their performance tests showed a slower rate of improvement than their unmedicated counterparts. They were slower to regain reflexes and slower to make their way through a specific kind of maze. It was previously argued that the newer so-called atypical antipsychotic drugs like Risperdal might be a better choice for aggressive or psychotic TBI patients. This study argues that there is no significant difference between the older and newer drugs. What does that mean for humans with brain injuries? In a nutshell, these results argue for avoidance of antipsychotic medications while recovering from TBI unless absolutely necessary.
