Determining Age-Related versus Mild Traumatic Brain Injury-Related Cognitive Decline in Individuals 75 Years of Age or Older
If there is just one thing learned over the past 20 years with regard to TBI including MBI, it’s that traumatic brain injuries do not discriminate. Any person can sustain a brain injury at any time and from many causes.
The geriatric population is the most “at-risk” population for injuries as the result of a fall. Statistics show us that this is the highest age population for cognitive decline which includes short-term memory loss, general forgetfulness, and confusion. With these deficits, frustration from not being able to recall simple information can turn to anger as well as aggression including blaming others. Some behavioral changes can include paranoia, which can stem from another individual sharing or correcting information with the older person who can perceive he or she is being fooled or purposely mislead.
Over the past 30 years, the work force in America has increased in age. The oldest baby-boomers, historically raised by parents with a strong work ethic, continue to work into their 60’s and 70’s. Many individuals in their 80’s go back to work part time, seeking jobs with flexible and sometimes shared hours such as crossing guards and school bus drivers. Both of these positions are risk positions for falls and car accidents. One would believe that employers recognize there can be a significant risk placing the geriatric population in these positions. However, informal observation of crossing guards and school bus drivers reveals a high number of individuals 65 and older driving school buses and crossing children at crosswalks.
Examining the separate cases of two 75+ years of age individuals who were working part-time in high-risk positions, it is evident balance is a basic issue related to falls as is the risk of a car accidents. Following each injury, each employer indicated verbally, and almost identically, to the workers’ compensation carriers in each case that the employee was “part-time,” “having difficulties keeping up” at work, was “reprimanded recently,” and was “close to being terminated.” There was no documentation in either individual’s employee file indicating there were any performance problems. Attendance during the last performance review for one was “outstanding” and “excellent” for the other.
Each individual was initially treated in a hospital. Both underwent acute rehabilitation for several weeks and each was discharged home with 24/7 attendant care primarily due to cognitive deficits and secondarily due to ambulatory and balance deficits. Each workers’ compensation carrier referred each claimant to a residential post-acute neurological rehabilitation program for a comprehensive evaluation, including neuropsychological evaluation, cognitive evaluation, occupational therapy, physical and vestibular therapy, community assessment, and observation in all environments. General health improved significantly in the residential post-acute programs due to lack of medical management and regular follow-up prior to each injury. In a structured and supervised environment and under the direct care of a physician, each individual was medically managed holistically while undergoing neurorehabilitation (non work-related medical issues were not the responsibility of the workers’ compensation carriers). It appeared that and it was opined that recovery from brain injury was enhanced once each individual was placed on general health protocols, prescribed medications for specific health diagnoses, and maintained a well-balanced and nutritious diet while in the residential post-acute neurorehab program.
Through each neurorehabilitation course, neuropsychological evaluation identified specific areas of cognitive deficits. More specialized testing became necessary over time to help determine the “normal” age-related cognitive decline versus the extent of the cognitive decline as a result of the brain injury. Breaking down the percentage of accident-related (TBI/MBI) decline versus age-related decline is important to workers’ compensation carriers when costing out the financial resources. Given the normal aging process combined with the TBI/MBI diagnosis, it is anticipated that the injured worker will require any one of the following: care and treatment in a supported living program; or specialized assisted living facility; or supported apartment program; or close supervision and specialized services being cared for by a loved one in a home environment; or services from a home health agency specializing in neurological care.
In each of the two cases, the specialized methods of testing and evaluation within the residential post-acute neurorehabilitation program were successful in determining the percentage split of injury-related versus age-related cognitive decline which was beneficial to each of the workers’ compensations carriers. This resulted in each injured worker receiving appropriate and clinically relevant support and care with medical management of their pre-existing medical issues in an environment that met their individualized needs and wants for the best possible life following TBI/MBI.
