Traumatic Brain Injuries: A Growing Concern, Especially for Aging Adults and Their Families
Traumatic Brain Injuries (TBIs) are a significant public health concern, particularly among older adults. According to the Centers for Disease Control and Prevention (CDC), approximately 2.8 million people in the United States sustain a TBI each year, leading to numerous hospitalizations and deaths.
Older adults are especially vulnerable due to factors such as decreased balance and physical frailty, which increase the likelihood of falls—a leading cause of TBIs in this age group.
Knowing the types of TBIs can help your loved one get the proper care. TBIs range from mild concussions to severe brain damage. Mild TBIs might cause temporary confusion and headaches. In contrast, severe TBIs can lead to extended unconsciousness, permanent disability, or even death. Understanding the severity and specific type of injury is crucial for determining the appropriate medical and rehabilitation services needed.
TBIs and Older Adults
TBIs are hard for anyone, no matter the age; however, the effects of TBIs on older adults can be profound and life-altering. These injuries often result in long-term cognitive, physical, and emotional impairments. Common consequences include memory loss, difficulties with speech and language, impaired motor skills, and changes in mood or personality. These impairments can severely limit an individual's ability to perform daily activities, leading to a loss of independence and a need for ongoing care and support.
A study by UC San Francisco and the San Francisco VA Health Care System found that 13% of older adults are diagnosed with traumatic brain injury (TBI). These injuries are typically caused by falls from ground level.
Researchers tracked approximately 9,200 Medicare enrollees, with an average starting age of 75. Contrary to other studies focusing on younger populations, this study found that being female, white, healthier, and wealthier was associated with a higher risk of TBI.
“The number of people 65 and older with TBI is shockingly high,” said senior author Raquel Gardner, MD, formerly of the UCSF Department of Neurology and the San Francisco VA Health Care System.
Taking measures to optimize safety and mitigate falls is critical. These measures need to change over the life-course as an individual accumulates physical or cognitive disabilities, or both.
For families, the impact of a TBI on an older adult can be overwhelming. Family members often find themselves in the role of primary caregivers, which can be both physically and emotionally demanding. The sudden change in a loved one's health can strain family dynamics and finances.
According to the Family Caregiver Alliance, caregivers of individuals with TBIs often experience high levels of stress, anxiety, and depression as they navigate the complexities of providing care and managing medical needs.
Moreover, the financial burden associated with TBIs can be substantial. Costs can include medical expenses, rehabilitation, home modifications, and the potential need for long-term care services. The emotional toll on families is equally significant as they adjust to the new realities of their loved one's capabilities and health status.
Types of TBIs
Knowing the types of TBIs and their specific implications is crucial for ensuring proper care and treatment.
Concussion
A concussion is the most common type of TBI. It occurs when the brain is abruptly shaken inside the skull due to a blow to the head. Common symptoms include headaches, confusion, dizziness, and memory issues. Some people might also experience nausea, vomiting, or sensitivity to light and noise.
Although concussions are often considered mild, they can have serious long-term effects if not treated correctly. Multiple concussions can lead to chronic traumatic encephalopathy (CTE), a degenerative brain disease.
Concussions in older adults are primarily caused by falls, which are the leading cause of traumatic brain injuries (TBIs) in this age group. According to the Centers for Disease Control and Prevention (CDC), over 3 million older adults are treated in emergency departments annually due to fall-related injuries, with many of these injuries resulting in concussions.
As people age, they often experience reduced balance, weaker muscles, and decreased bone density, making them more susceptible to falls. Conditions such as osteoporosis and arthritis further increase the risk of falling and sustaining a concussion.
In addition to falls, motor vehicle accidents are another common cause of concussions among older adults. Age-related changes in vision, hearing, and reaction time can make driving more hazardous, leading to an increased likelihood of accidents. Even minor car accidents can result in significant head trauma for older adults due to the fragility of their bones and tissues.
Furthermore, older adults are more prone to suffering from concussions due to incidents like being struck by or against objects. This can occur during daily activities such as walking, gardening, or even simple household chores. The combination of decreased physical coordination and slower reflexes makes it harder for older adults to avoid these types of accidents.
Contusion
A contusion is a bruise on the brain itself, often resulting from a direct hit to the head that causes the brain to bleed and swell. Symptoms of a brain contusion can be similar to those of a concussion but may also include difficulty with coordination, speech, and vision.
Severe contusions can cause significant damage and might require surgery to reduce pressure. The severity often depends on the impact's force and the injury's location. Immediate medical attention is crucial for a proper assessment and treatment plan.
The causes of brain contusions are similar to concussions.
- Falls: Similar to concussions, falls are a leading cause of brain contusions in older adults. The impact of a fall can cause the brain to strike the inside of the skull, leading to bruising and swelling. Reduced balance and muscle strength, common in older adults, increase the risk of falls and subsequent brain contusions.
- Motor Vehicle Accidents: Motor vehicle accidents can also result in brain contusions. The force of a collision can cause the brain to impact the skull, leading to bruising. Older adults are more vulnerable to severe injuries from accidents due to age-related physical changes.
- Being Struck By or Against Objects: Incidents involving being struck by or against objects are another common cause of brain contusions. This can occur during everyday activities such as walking, gardening, or performing household chores. Decreased physical coordination and slower reflexes make it harder for older adults to avoid these types of accidents.
Diffuse Axonal Injury
Diffuse Axonal Injury (DAI) is one of the most severe types of traumatic brain injury (TBI). It occurs when the brain rapidly shifts inside the skull, causing the tearing of nerve fibers. This type of injury is often seen in high-impact events such as car accidents and falls from significant heights. Symptoms of DAI can include loss of consciousness, coma, and severe neurological impairment.
Recovery from DAI is typically slow and involves extensive rehabilitation. The extent of recovery depends on the severity of the injury and the specific areas of the brain that are affected. In severe cases, DAI can result in permanent disability or even be fatal. Long-term rehabilitation may include physical, occupational, and speech therapy to help regain lost functions and improve quality of life.
The impact of DAI on older adults is particularly severe due to several factors. In older adults, DAI can lead to profound and long-lasting symptoms, including:
- Loss of Consciousness: Often immediate and may persist for extended periods.
- Coma: In severe cases, DAI can result in prolonged comatose states.
- Neurological Impairment: Severe impairments in cognitive and motor functions, which can lead to difficulties in speech, memory, coordination, and daily activities.
- Permanent Disability: Higher likelihood of long-term or permanent disability due to reduced brain plasticity in older adults.
- Recovery from DAI in older adults is often slow and requires extensive rehabilitation:
- Age-Related Decline: Older brains have less neuroplasticity, making it harder to recover lost functions.
- Pre-existing Conditions: Chronic illnesses like diabetes, hypertension, and cardiovascular disease can complicate recovery.
- Rehabilitation Needs: Intensive rehabilitation, including physical, occupational, and speech therapy, is typically required. However, the effectiveness may be limited compared to younger individuals.
Older adults with DAI have a higher risk of mortality compared to younger individuals. The severity of the injury combined with age-related health issues can lead to complications such as infections, respiratory issues, and other medical problems.
DAI can severely affect the quality of life for older adults, including:
- Loss of Independence: The need for continuous long-term care and support can lead to a loss of independence.
- Emotional and Psychological Effects: Increased risk of depression, anxiety, and other mental health issues due to the dramatic changes in lifestyle and abilities.
- Burden on Caregivers: The need for long-term care can place a significant emotional, physical, and financial burden on family members and caregivers.
Penetrating Injury
Penetrating brain injuries happen when an object pierces the skull and enters the brain tissue, typically caused by bullets, shrapnel, or other sharp objects. Symptoms depend on the brain part affected but can include loss of function in certain body parts, cognitive deficits, and seizures.
These injuries are hazardous and require immediate surgery. The outcome varies widely based on the location and extent of the damage. Prompt medical care and rehabilitation are crucial for recovery.
Second Impact Syndrome
Second impact syndrome (SIS) occurs when a person experiences a second concussion before the first one has fully healed, causing the brain to swell quickly and severely, which can be deadly. SIS is rare but most common in young athletes who return to sports too soon after an initial concussion.
Symptoms can escalate quickly, including loss of consciousness, respiratory failure, and even death. Preventing SIS involves ensuring that individuals with concussions do not return to high-risk activities prematurely. Proper medical clearance is essential before resuming any physical activity.
TBIs in Older Adults: Prevention, Care, and Future Planning
Traumatic Brain Injuries pose a significant risk to older adults, with profound impacts on their health, independence, and quality of life. The consequences of TBIs in older adults often extend beyond the individual, placing emotional, physical, and financial burdens on families and caregivers.
Concerns About Long-Term Care
The need for long-term care following a TBI is a critical concern. Older adults who suffer from severe TBIs may require continuous medical care, support with daily activities, and specialized rehabilitation services.
This level of care can be costly, and health insurance and Medicare will only cover short-term skilled care. Long-Term Care Insurance will pay for long-term care services if a policy is in force. Medicaid pays for long-term care for those with limited financial resources.
If your loved one requires long-term care due to an accident caused by someone else's negligence, a lawyer can help recover the costs associated with your medical expenses and long-term care needs. Legal expertise can be crucial in navigating the complexities of personal injury claims, ensuring you receive the compensation you deserve to cover these substantial costs.
Many families may face difficult decisions regarding providing and funding necessary care, which can deplete savings and place additional stress on loved ones. Finding quality long-term care services can also is hard on loved ones. The LTC NEWS Caregiver Directory can help you find the right care services.
Reducing the Risk of TBIs in Older Adults
Preventing TBIs in older adults involves addressing the most common causes, such as falls and motor vehicle accidents. Here are some ways to reduce these risks:
- Fall Prevention: Implement home safety measures such as removing trip hazards, installing grab bars and handrails, ensuring adequate lighting, and using non-slip mats. Regular physical exercise can improve balance and strength, reducing the likelihood of falls.
- Safe Driving Practices: Encourage regular vision and hearing check-ups, limit driving at night or in poor weather conditions, and consider alternative transportation options if necessary. Driver refresher courses designed for older adults can also be beneficial.
- Home Safety: Secure loose rugs, keep frequently used items within easy reach, and avoid cluttered walkways. Proper footwear can also reduce the risk of slips and falls.
- Regular Health Check-ups: Regular medical check-ups can help manage chronic conditions that increase the risk of falls, such as osteoporosis and arthritis. Proper medication management is also crucial to avoid side effects that may impair balance and coordination.
Final Thoughts
Addressing the risks and impacts of TBIs in older adults requires a multifaceted approach involving prevention, early intervention, and comprehensive care planning. By taking proactive measures to enhance safety and by planning for potential long-term care needs, older adults and their families can better navigate the challenges posed by TBIs.
