CTE and its violent underpining

WESTBOROUGH, MA January 20, 2018 More is becoming known about Chronic Traumatic Encephalopathy or CTE.  It is now able to be diagnosed prior to the death of the patient by identifying unique protein markers in the blood of those who have sustained multiple brain injuries.  Former professional wrestler Chris Benoit was found to have CTE after killing his wife and son before killing himself in 2007. But murder or other violence against others has not typically been associated with CTE until recently.  As recently as summer, 2017, the brain of former N.E. Patriots star Aaron Hernandez was also found to have signs of severe CTE raising the specter of its possible impact on his violent life and eventual death by suicide. I have posted post-mortem photos of his brain first published on the Boston University site in a prior blog on my Concussion site (Sefton, 2017).  See that post by clicking here.  It is now understood that an athlete need not have sustained numerous concussions in his career to be found to have CTE at time of death.  More so, the accumulation of repeated blows to the head – subconcussive force – is being implicated in the etiology of this complex disease process. So contact sports like football, rugby and ice hockey are being closely scrutinized by experts in concussion, athletic training and sports medicine.  Researchers at BU School of Medicine have reported that a protein known as CLL11 may be elevated in the brain and spinal fluid of athletes with a history of brain injury.  It holds some promise of being able to diagnose athletes before death.  This protein leads to elevate Tau protein a known cause of progressive brain damage associated with dementia.
In 2014, The K.C. Star reported that analysis of Belcher’s brain after he’d been exhumed revealed a key signature of chronic traumatic encephalopathy, best known as CTE, a degenerative brain disease found to cause dementia, confusion, depression and aggression). “Belcher’s murder-suicide is the worst possible example of domestic violence, and these findings come as the NFL is under attack for its handling of domestic violence.” (Mellinger, 2014 Kansas City Star). 
“CTE has been found to cause erratic and sometimes tragic behavior by some NFL players, perhaps most notably Hall of Fame linebacker Junior Seau, who killed himself last year. The disease, only recently diagnosable before death, has often been found in former and longtime football players.” Mellinger, 2014 K.C. Star
 Riding a bicycle is a leading cause of brain injury in childhood. Recently, CTE has not been diagnosable before death. It has been found over and over in former and longtime football players. Domestic violence behaviors cut across all socioeconomic strata.  They germinate in an environment of secrecy often early in courtship.  During this time abusive spouse slowly isolates his intimate partner from her support – family, friends, finances.  “In doing so there is a subtle but undeniable manipulation of control – usually coupled with threats and intimidation.  There is growing awareness that red flag behaviors precede DV and domestic violence homicide.  Things like pathological jealousy, forced sexual contact, manipulating friendships, detachment from members of immediate family and others are the early signs of domestic violence.” (Sefton, 2012)  Some believe that the most significant pre-incident red flag is whether or not the victim truly believes she is going to be killed by her intimate partner one day and that these victims are at most risk of death.

Brain and Behavior: B.U. scientist says Aaron Hernandez had CTE

Westborough, MA November 18, 2017 The NFL has some explaining to do. Why are former athletes killing themselves and in some cases other people? As students studying the brain it was something special when you could make a correlation between an identified brain lesion and the behavior you are seeing.  I was in China in early November 2017 at a conference on RNA targeted therapy for cancer.  As the non-scientist in the group I was referred to as the clinician who saw the phenotype rather than the genotype – referring to the innumerable genetic underpinnings of cellular biology and changing science of modified nucleotides.  I understood this to have some meaningful interest to the faculty that consisted of 3 prior Nobel laureates and leading scientists in RNA targeted therapy.  So after sitting through hours of presentations I realize the importance of not making a rush to judgment about the cause of some predicted outcome. As a neuropsychologist we are asked to make assumptions about brain integrity after CNS infarcts and make educated predictions about the functional implication of focal lesions in brain.
Recently the scientists at Boston University announced the results of the post-mortem analysis of the brain of Aaron Hernandez, former N.E. Patriots receiver and convicted murderer.  Hernandez had his conviction expunged after he died while his case was on appeal. The 27-year old brain was highly suggestive of having the tell tale signs of chronic traumatic encephalopathy or CTE thought to be the result of repeated concussions and now realized as the result of hundreds – perhaps thousands of sub-concussive blows to the head that accumulate over time.  Hernandez’s brain was the youngest of the donated brains to be identified with advanced CTE. Hernandez played football for 17 years starting when he was a young boy. The question remains did the brain damage that was identified in the post-mortem analysis cause behavior change in Hernandez and could the murder of Odin Lloyd be attributed to the build up of dangerous tau protein in his brain?
“While no one can prove a causal link between Hernandez’s brain damage and his actions, there is little dispute that he displayed CTE symptoms associated with behavioral problems, such as aggressiveness, explosiveness, impulsivity, and suicide.”
Boston Globe Bob Hohler November 9, 2017
By history Aaron Hernandez was an angry, impulsive and violent teenager that his mother reported began when his father died suddenly. Coupled with this was a biological proclivity toward degenerative brain disorders such as Alzheimer’s Disease and CTE.  Both are diagnosed only after the death of the victim. We know that brain-behavior relationships exist from research in stroke and traumatic brain injury where focal injuries result in specific and expected changes in behavior.  These often result from a disconnection between functional centers of the brain including limbic structures that link centers for emotional regulation and the frontal system that exerts inhibitory control over those emotions. The athlete’s who have donated their brain’s upon their death have almost universally exhibited changes in behavior including poor impulse control, depression, and anger.

Clock of the Week

Dr. Michael Sefton at Boston Museum of Fine Arts
WESTBOROUGH, MA September 15, 2017  Much has been published about the utility of the clock drawing in making preliminary assumptions about the cognitive health of an individual who may be referred for neuropsychological assessment.  I use it all the time and those of you who have submitted clocks for publication here agree with my assumptions.  The photograph at the left was taken at the Boston Museum of Fine Arts by a colleague Dr. David Kent, a neuropsychologist from Worcester, MA. There are several posts that identify some of the literature behind the assumptions I make about clock drawing and cognition.  Here is another link: Clocks and cognition

The results of postmortem examination of over 100 brains of NFL athletes are in

WESTBOROUGH,MA July 25, 2017 The laboratory at the Boston University School of Medicine has recently completed its initial examination of over 100 brains donated by the family members of those athletes who have died because of marked behavior and personality changes attributed to playing football.  The results confirm the presence of destructive proteins that have come to be known as chronic traumatic encephalopathy.  This was first reported over 10 years ago and was featured in the movie Concussion released in 2015 starring Will Smith as Bennet Omalu, M.D. who first reported on the syndrome.

Clock of the Week June 6

Westborough, MA June 6, 2017 The clock of the week is depicted below.  It was submitted this week by the Speech Language Pathology service at Whittier Rehabilitation Hospital.  I sometimes find it humorous that when I ask a patient to draw a clock they will have already drawn a clock for the speech pathologist. The drawing is used in all aspects of cognitive assessment by pracititioners of all types from neuropsychology to internal medicine to emergency medicine.  I typically begin an assessment with the clock drawing because it is nonthreatening and offers a great deal of interesting information about the cognitive capacity of the patient.  It was drawn by a 93-year old male with congestive heart

failure and Paget’s disease. It is a disease affecting bone that interferes with the body’s normal recycling process, in which new bone tissue gradually replaces old bone tissue. Over time, the disease can cause affected bones to become fragile and misshapen (Mayo Clinic, 2017). In my experience there is no cognitive deficits associated with Paget’s.  This clock is suggestive of what seemed to be a great start – in terms of the initial placement of the numbers although as you can see the numbers 1-6 were drawn on both sides of the circle. This is an unusual finding suggesting decreased problem solving and self-monitoring on behalf of the patient.  The SLP drew the circle for the patient. I would suggest that the patient should be allowed to create his or her own circle as this can provide interesting data as well.  I once had a patient draw and elaborate grandfather clock fit for a castle.  The clock face became secondary and insignificant – for him.  The clock is a regular feature here at Concussion Assessment and Management.  
Anyone can submit a clock for consideration of the clock of the week.  Upload to my email address: msefton@whittierhealth.com – No identifying HIPPA protected information please but a brief overview is always helpful.

The Trial and Error Associated with Cognitive Decline

Westborough, MA May 25, 2017 Cognitive changes are common in patients with dementia. They become increasingly problematic with the disease progression. Some people suffering with dementia have difficulty with even the most basic activity of daily living like dressing themself.  Things taken for granted like following directions become a chore as the progression of dementia effects individuals who suffer with the disease.  This places a great burden on caregivers who must take over those important functions of daily life.
The clock drawing has been a feature on my blog for several years.  It is fun to see people work through the task.  Most people complete the task effortlessly.  Some are a bit defensive because it seems like such a benign request – “draw a clock…” and I often get “I am not an artist…” in anticipation of failure.  I have published over a dozen posts about the clock drawing as a measure of cognitive functioning.  Patient with dementia often experience a slow cognitive decline whereby even tasks like constructing a clock become a challenge.

The clocks drawn in this post reflect the effort of a person of 89-years of age who tried very hard to get it right.  She had enough preservation of her self- monitoring

that she could tell something was wrong.  As you can see the left most circle was the first attempt.  It was too small according to the patient and she wanted to try again.  The middle clock was her next attempt and shows her disorganization and minimal change in the size of the drawing – approximately 3 centimeters in size. In the center of the drawing there are 2 hands that roughly represent the time 11:10.  She told me she needed more space to place the hands so that they could be clearly read and offered to try a third time.  On the right is her final attempt.  There are two hands (to the right of the number 9 and a second pointing to the number 2). As you can see the circle is only 2 cm in size and was a modest improvement over the first two attempts.
She had fun drawing the clock and did not feel as though she had failed the task. I was encouraging and praised her for staying with the task. At some point she had lost her capacity to plan and execute her visual motor function of crafting the circle.  Each attempt was made with the goal of drawing a larger circle. This fine woman was still capable of doing many of her activities of daily living and enjoying her friends and family.  She was not at all upset that I had been asked to help with her care.
Dementia requires family support and can be costly to those in need of care.  The risk of caregiver fatigue exists in all families.  As much as possible, I enourage people to allow the patient to work toward completing their own self-care unless there are risks such as falling due to poor balance. This requires herculean patience and sensitivity because there is often a degree of “awareness” of the cognitive changes experienced by the patient himself. Preserved dignity and sense of independence go a long way toward quality of life in the latter stages of dementia.  Most spouses will do whatever it takes to support a loved one with whom they have shared 50 or more years of marriage and experience the decline in functioning as both a personal failure and a heart breaking loss.

The cumulative impact of dementia on caregivers

dementia-symptoms-and-brain changesWESTBOROUGH, MA January 20, 2015  The impact of dementia is no greater than on those who remain behind to care for those afflicted with dementia.  Typically, this may be a singular spouse who has chosen to care for their loved one through the insideous stages of dementia.  Often in direct opposition to adult children, who may be intellectually dispassionate about what should or should not be done for the affected parent. This can take an enormous toll on the health of the surviving spouse who is often filled with guilt and sadness as they witness their life partner slowly fade away alone and often without substantive, hands on support.  No greater sense of despair and futility exists as when the declining husband or wife can no longer remember a devoted caregiver or the memory of a shared life. Even worse is the tangle of doubt over what more can be done. Their futility is painful to see for those who provide care for the patients and the caregivers.

Dementia and Aging

Dementia is a disease that most people have heard something about.  There are several variants of the disease including Alzheimer’s, Lewy Body, frontotemporal, and vascular dementia just to name a few of those more prevalent.  Most know the cluster of functional changes that occur with the slow but progressive loss of neurocognitive function that often starts deep within the brain in the 6th or 7th decade of life.  It starts with something as benign as forgetting a conversation after just a few minutes or being momentarily lost in a familiar place in town.  As the condition progresses, patients are rendered more forgetful, lose appreciation for tasks like paying bills, personal hygiene, eventually unable to recognize loved ones and care for their own basic needs.  As with any life changing sign of debility it is often difficult to admit and usually more difficult to address.  Denial is a common first reaction when dementia is suspected.  And feared.

There are many myths associated dementia that are worth pointing out.  First, old age and dementia are not synonymous.  Patients always say to me “what do you expect I am 82 years old” when I first begin the assessment process.  Research according to the APA, has shown in the right environment memory should not fail solely on the basis of age.  Next, there are many conditions that mimic dementia but are fully treatable if addressed sooner rather than later.  Arguably, depression, for example, often mimics dementia because of the associated change in attention memory, and behavior.  It is far more prevalent than Alzheimer’s and has a very high rate of treatment success.  The third myth is that there is nothing that can be done to stave off the mental inopertivity of senility. Wrong. But one needs to take responsibility for personal well-being long before the grip of dementia has begun unraveling one’s neurocognitive infrastructure.  This includes regular exercise, mental stimulation, nutritional balance, and regular social interaction.  It would not hurt to continue working or volunteering just to keep yourself in physical and cognitive shape. And finally, dementia is not life’s inevitable end point – whatever the age.  80 is the new 70 – people are living longer.  There are currently 96,000 centenarians in the United States.  In 30 years there will be over one million people who are over the age of 100.

Caregiver distress

Caregivers of dementia sufferers themselves suffer greatly.  The daily care of someone with dementia drains the emotional reserve needed to replenish the “self” unless the depleted caregiver can find a healthy, restorative balance.  The surviving spouse is sometimes under great stress to keep a loved one in his home – out of a nursing home. They anguish with each dying day in witness of a withering of human spirit – once father.  The decision to admit one’s spouse to a dementia care facility conjures up images of the locked wards, vitriolic nurses, and exploitive, uncaring staff – another myth germinated in the guilt and self-recrimination of husbands and wives, and families who have forever tried and failed to slow the disease.  Signs of caregiver burnout include sleep disturbance, irritability, being on edge, anxiety, unrecognized anger, and personal neglect.  Eventually, the stress associated with being a caregiver will errode whatever well-being may be left unless supoprt and balance can be found. No easy task – especially when a selfless spouse wants only to have things the way they were.

In truth, long-term care facilities are equipped to take care of someone with dementia with a round the clock team of nurses and rehabilitation therapists.  Making the decision to admit the demented family member may be aided by a family physician, knowledgable friend, or trusted therapist. Day treatment programs in many areas around the country provide temporary respite.  They are a good first step in diminishing caregiver fatigue. They offer free time to caregivers for restoration of empathy and the needed emotional refueling that comes from seeing friends, family, or dinner out, or a Sunday mass.

The best way to handle a situation like this is to surround oneself caring friends.  It is okay to talk about how difficult it may have become.  It is not a betrayal to feel angry inside or to reach out to family for respite care.  The financial concern over caring for a patient with dementia is very real.  It is expensive care to get and not readily available across the country or elsewhere.  Some hospitals or clinics offer free dementia care workshops or support groups that can provide helpful information and knowledge that you are not alone.  Learn what services are available in your area.  Talk to people and restore your self and believe that you are worthy of a rest – if even a short one.
