Traumatic brain injury (TBI) is a frequent but under-recognized condition co-occurring with substance use disorder (SUD). TBI can cause a wide range of cognitive and behavioral consequences that interfere with a client’s ability to adhere to substance abuse treatment.
Some clients with TBI enter substance abuse treatment with their injury diagnosed, while others may enter with an undiagnosed TBI that has lingering effects. Treatment counselors also may not recognize clients who have been affected by TBI because its effects overlap with those of SUD and other co-occurring conditions such as depression, generalized anxiety disorder, and posttraumatic stress disorder (PTSD).
Substance abuse treatment counselors need to be aware that TBI may be a health condition affecting their clients. Through observation and questioning, counselors can try to identify clients whose functioning is affected by TBI and who may require special strategies in their treatment for SUD. Counselors also can incorporate these important facts into relapse prevention messages for all clients: that substance abuse increases the likelihood of a first or recurrent TBI and that TBI compounds the brain function problems caused by substance abuse.
What Are the Links Between SUD and TBI?
Epidemiological surveys have established that acute intoxication or SUD dramatically increases risk of TBI and impairs TBI recovery. The data are described below.
History of substance abuse is a risk factor for TBI.
Among patients hospitalized for TBI, between one-third and four-fifths have histories of substance misuse, with alcohol being the most commonly reported misused substance.6,7,8
Alcohol use at time of injury is a common occurrence with TBI.
Approximately three-quarters of all patients with TBI have measurable amounts of alcohol in their blood when admitted to the hospital,8 and one-third to one-half of them are intoxicated at the time of injury.6,7
Prior TBI is common among individuals in substance abuse treatment.
In a review of five studies of people in substance abuse treatment, estimates for prior TBI ranged from 38 percent to 63 percent.9 In another study of 7,784 adults in State-funded substance abuse treatment programs, almost one-third of persons assessed at intake reported a history of one or more head injuries for which they lost consciousness or were hospitalized at least 1 night.10
Substance abuse is linked to worse outcomes from TBI.
Brain imaging studies and neuropsychological testing indicate that SUD and TBI compound the negative effects each has on brain structure and function.9 A substance abuse history is associated with worse outcomes from TBI including greater likelihood of mortality, complications, and poorer hospital or emergency department discharge status,6 as well as ongoing disability and nonproductivity a year or more after brain injury.11
Substance abuse is linked to recurrent TBI.
TBI related to alcohol use increases the risk of subsequent TBI, often alcohol-related; this risk extends for several years after the first injury.12
It is not yet known whether a TBI itself increases risk of SUD in persons otherwise not at psychological or psychiatric risk of addiction at the time of injury. Some evidence suggests that TBI, especially to frontal cortex regions, may induce deficits in executive function (cognitive processes affecting mental control and self-regulation) that confer risk for SUD generally.13
Is TBI Diagnosed?
TBI is initially diagnosed as mild, moderate, or severe, based on the individual’s condition at the time of injury. About 75 percent of all TBIs are mild.14 Concussion is often used as a synonym for mild TBI, especially in reference to sports injuries.
A TBI diagnosis is based on one or more of the following criteria: loss of consciousness, memory loss for events immediately before or after the injury, confusion and disorientation, and neurologic signs such as a wound to the skull, seizures, or headache15 (a person who does not lose consciousness may still be diagnosed with TBI if other criteria are met). Brain imaging techniques such as computed tomography or magnetic resonance imaging (commonly referred to as CT scan and MRI, respectively) can sometimes capture signs of TBI. Patients with moderate or severe TBI may have pronounced physical symptoms such as paralysis.
Compared with moderate or severe TBI, mild TBI can be difficult to diagnose because the acute symptoms and signs resolve quickly in most people and there may not be a visible head wound to indicate injury. In many cases, brain imaging is inconclusive and does not aid in diagnosis.15 Also, many people who incur a mild TBI do not seek medical treatment. As a result of these diagnostic challenges, clients in substance abuse treatment may not report a prior TBI when providing their medical history on admission.
What Are the Effects of TBI?
In the days or weeks after a brain injury, cognitive effects may emerge involving the ability to think efficiently, multitask, and persevere at a task without becoming mentally exhausted or irritable.16 Some individuals have impaired executive function. Their sensory functions may be affected so that light levels seem too bright and normal noises too loud and distracting. These people also may have reduced capacity to read, see, or hear. Social judgment, self-awareness, and regulation of emotions may be affected. Exhibit 1 lists common effects of TBI. This list should be interpreted with caution, because many of the effects are characteristic of other psychiatric disorders, including affective disorders and addiction. Substance abuse treatment counselors should therefore be aware that these effects may be difficult to differentiate from the effects of a psychiatric disorder, SUD, or withdrawal. The level and duration of TBI effects vary dramatically from person to person depending on the severity and location of the brain injury, time that has elapsed since injury, the individual’s age when injured (injury during childhood and adolescence carries more risk), health and cognitive status of the individual before injury, rehabilitation provided after injury, and substance abuse history.

Are TBI Effects Permanent?
Many individuals with TBI make a full recovery—some quickly and others over weeks or months. However, even mild TBI can have long-lasting cognitive and behavioral effects that impair the ability to work and engage in usual activities. Multiple TBIs are cumulative in effect and, even if mild, can result in severe brain damage.
Approximately 1 percent of the U.S. civilian population, or 3.17 million people, are living with a long-term disability from TBI that may limit their ability to work or perform daily activities without assistance.20 Some individuals who appear to have recovered find that their symptoms recur when they are under stress.
How Does TBI Affect Substance Use?
TBI is strongly associated with subsequent abstinence or reduced consumption.21,22,23 Factors contributing to reduced substance use include intense clinical monitoring during hospitalization or advice from outpatient healthcare providers to abstain, decreased access to alcohol or drugs (e.g., because of physical disability or close monitoring by caregivers), decreased tolerance to substances, or decisions to make life changes after the brain injury. For some, however, the reduction in use is only temporary.23
A minority begins drinking or increases alcohol consumption in the first year after injury.21,22 A history of substance abuse before sustaining a TBI is a risk factor for heavy drinking afterward.21,22 In addition, stimulants and opioid analgesics frequently used to treat cognitive disruption or pain from the TBI have abuse potential. These substance use patterns have several implications for treatment counselors:
- TBI can be a triggering event that impels clients to reform their substance use patterns.
- Elapsed time from TBI increases the risk for return to former patterns of abuse.
- Individuals with abuse patterns before the injury may need increased continuing care and extra emphasis on relapse prevention.
Is TBI Linked to Other Conditions Besides SUD?
Several conditions that frequently co-occur with SUD also co-occur with TBI. These conditions can complicate the substance abuse treatment provider’s effort to determine whether TBI is contributing to a client’s difficulty in treatment.
Risk is elevated for psychiatric disorders following TBI. Susceptibility is greatest for depression, generalized anxiety disorder, and PTSD.24,25,26 Conversely, risk is elevated for TBI among individuals diagnosed with such psychiatric disorders.27
The risk for committing suicide is two to four times greater for individuals with TBI than for the general population.28 Even mild brain injury increases risk. When a psychiatric disorder or SUD co-occurs with TBI, the risk for attempted or completed suicide is further increased.28,29
Chronic pain is another disorder that can co-occur with a client’s TBI. It affects about half of all individuals with TBI, even those with mild injury.30 The co-occurrence of PTSD with TBI appears to exacerbate pain.
How Can a Counselor Tell Whether a Client Is Affected by TBI?
Consistent failure in completing tasks, disinterest, inappropriate social behavior, lack of self-awareness, and tangential speech (making irrelevant and unrelated statements) are among the red-flag behaviors of the person with TBI. They also are typical for the client in substance abuse treatment. Counselors are advised to investigate whether head injury is involved before imposing consequences for a client’s nonadherent treatment behavior. Counselors can ask questions using simple, nonmedical terms: “Have you ever been knocked out?” or “Did you lose any memory after being hit?” For young clients especially, it may be appropriate to ask about involvement with contact sports such as football that may have caused hits to the head. To help differentiate between a true thought disorder, psychosis, and other psychiatric disorders, it is important to use a valid and reliable structured or semistructured interview when conducting an assessment. Exhibit 2 provides links to such tools. Counselors should follow their facility’s procedures for referring clients with suspected TBI impairments to a physician (preferably one who is familiar with both SUD and TBI) for a thorough assessment.
Exhibit 2. TBI Screening and Management Tools
The Ohio Valley Center for Brain Injury Prevention and Rehabilitation has developed a screening tool for use by nonexperts to identify clients who may need support in treatment because of a TBI history. The T-B-I Screening Tool uses a series of questions to help clients recall and characterize head injuries.31 It also includes information for working with clients who have TBI. The tool can be accessed at http://www. tbied.com/media/2009/06/15/TBI-Screening_v2_.pdf.
A clinical practice guideline from the Department of Veterans Affairs and the Department of Defense includes a structured interview for collecting head trauma event characteristics (Appendix B) as well as management guidance for the individual with concussion/mild TBI.32 It can be accessed at http://www.healthquality.va.gov/mtbi/concussion_mtbi_ full_1_0.pdf.

Clients referred into treatment for TBI may be able to access a range of rehabilitative services, including exercises to improve memory, problemsolving ability, attention span, speech, reading, and physical functioning; instruction in coping and compensatory strategies; and skills and vocational retraining. TBI treatment also can include therapy and medication to treat injury symptoms such as seizures, pain, anxiety, depression, or sleep problems.
The tools listed in Exhibit 2 can be helpful to substance abuse treatment counselors who have clients with TBI-related cognitive limitations. Such clients can benefit
from a low-stimulus counseling environment with few distractions and frequent rest breaks. They also are best supported by structured instruction, presented in a variety of formats and aimed at helping them acquire adaptive and coping skills.
Counselors may need to keep the pace slow and to repeat information frequently, in short and concise segments. Feedback (including feedback on behavior) should be specific, immediate, direct, and positive. Counselors should keep in mind that inappropriate client behavior may be unintentional; in such cases, the client can benefit from gentle redirection. Counselors should avoid confrontation, which can agitate the client and shut down thinking. Counselors also can encourage clients to rehearse desired actions and to adopt reminder systems such as calendars, lists, or electronic devices like those described in Exhibit 3 (see next page). Other actions counselors can take are suggested below.
Coordinate with other providers of care.
Collaborative care teams can include physicians as well as specialists for physical and neurological rehabilitation, psychiatric disorders, vocational rehabilitation, employment services, and family support services. Case management services are helpful for clients with co-occurring SUD and TBI.34 If the case manager is not from the substance abuse treatment facility, the counselor may have to educate the case manager about substance abuse treatment and how it affects a client’s needs.
Promote an expectation that the brain injury will heal.
Many TBIs resolve over time. This reassurance can contribute to recovery from TBI. The client who is frustrated and discouraged can be helped by knowing that the head will continue to “clear” and his or her ability to adhere to the recovery plan will improve with time and practice.
Educate clients about the need to remain abstinent to avoid another TBI.8 Counselors can reinforce the client’s motivation for recovery by emphasizing that relapse can worsen the adverse cognitive and emotional effects of his or her TBI. Relapse also increases risk of a repeat TBI, which can cause even greater brain damage.
Encourage clients to join a TBI support group.
Rehabilitation facilities often organize TBI support groups. Alternatively, substance abuse treatment programs can form in-house groups or provide peer mentors for clients affected by TBI.
A small gift certificate (e.g., $20) for completing the intake process can accelerate the decision by a person with TBI to commit to a substance abuse treatment plan.35 Gift certificates also can positively affect early attendance and retention.36
Offer motivational support.
Clients with TBI may benefit from systematic motivational counseling (an
intensive form of motivational counseling) when it is used as an adjunct to other therapeutic techniques.37 Booster sessions following motivational counseling may help clients remain abstinent.
Support client’s coping skills.
Positive coping styles (e.g., actively addressing the problem, using humor to counteract stress, making time for enjoyable activities) help the client with SUD and TBI adjust to the distress that accompanies decreased functional ability. These adjustments in turn may reinforce effective coping.38
Exhibit 3. Assistive Technologies for Clients with TBI
Cell phones, smart phones, and other forms of personal digital assistants can be used by clients with cognitive issues to remember essential information, navigate daily tasks, be reminded of appointments or times to take medication, and stay focused on treatment goals. Counselors can send the client text messages or voice reminders (these can be automated), and they can help the client program the devices to provide timer beeps, visual cues, maps, or other cognitive aids. A database of the burgeoning variety of assistive devices and software is available at http://www.abledata.com.
