WESTBOROUGH, MA November 10, 2016 You may be interested in the Clock of the week on this day after the presidential election of Donald J. Trump. It was drawn by a male with obvious cognitive dysfunction. The task is simple – draw a clock and set the hands for 11:10. In this case the patient became stuck. He asked me “how do I do it” and I replied start with the circle. As you may notice the man drew the large circle quite well. I thought to myself “hmm, not bad”. Next he drew one small circle after another. Finally he was able to approximate the minute hand only – as you can plainly see it is set juxtapose where the 2 might be.
Dementia is an insidious neurological disease that robs patients of their mental functioning – including memory, problem solving and the capacity to think with critical acumen. The late president Ronald Reagan succumbed to dementia of the Alzheimer’s type in 2004 after a decade of declining cognitive prowess. He was 69 when he entered the White House. It has grown more prevalent in the past decade. Neuropsychologists are uniquely qualified to manage the cognitive and behavioral changes associated with dementia. There is no cure for dementia at the present time. Exercise and mental activity are two components of maintaining a healthy mind and body into one’s old age. My practice is filled with older patients many of whom do not believe in the adage about old age being “the golden years”. In fact, many older patients are lonely and demoralized. Many are afraid of what the next president may do to their healthcare, housing and social security pensions.
Let us hope that our next president will maintain his mental faculties well into old age. His somewhat unbridled behavior is not unlike that of patients suffering with some forms of dementia that negatively impacts judgment, planning and decision-making. Mr. Trump will be 70 years old when he enters the White House in January 2017. The oldest man to ever be elected to the office of the president.
WESTBOROUGH, MA October 7, 2016 The clock of the week brings up an interesting question. What is encephalopathy? I hear that all the time from patients and more likely, family members who are confused as to the definition of encephalopathy. I will make an effort in this blog to provide some explanation for this. Look at the clock and see that is quite confused. Remember prior published clocks and the fact that the directions are exactly the same for every person. “Draw the face of a clock, put all the numbers on it and set the hands for 11:10”. Essentially it is a three step command that requires both attention and problem solving. In prior published blogs and You Tube videos I have made an effort to illustrate the range of clocks given by patients of various diagnostic classifications.
Encephalopathy is a common manifestation in patients with sepsis (infectious illness) such as pneumonia and urinary track infection, delayed hemodialysis, and many others. In refers to brain dysfunction often due to multifactorial issues including metabolic and infectious causes. According to the Health Line encephalopathy may be temporary or permanent. The patient who created the illustrated drawing was very cooperative but subject to altered mental status when getting sick, fatigued or on dialysis days. The treatment for encephalopathy depends on the underlying reason for the AMS but largely is treating the symptom picture to manage the patient comfortably.
Symptoms of encephalopathy often begin rapidly and may be seen as confused behavior, decreased attention, and poor problem solving. Neuropsychology services across the country are referred these patients in earnest in hope of tracking changes in their cognitive status and behavior. The assessment process is lengthy. At some point, patients are asked to make up a sentence containing a noun and a verb as part of the basic cognitive screening. As you can see from the illustration below, this patient had difficulty with this task. Almost any sentence will suffice but in this case the woman added the heart to represent the word ‘love’ and placed a smiley face at the bottom of her page to indicate her completion of the task. Persons with encephalopathy often exhibit unusual limitations in their awareness of their condition and exhibit varying levels of confusion throughout the day. Slowly these symptoms resolve – sometimes quite rapidly. Just as rapidly, some patients are vulnerable to altered mental status at the first sign of infection.
WESTBOROUGH, MA October 8, 2016 Second impact syndrome is a rare but generally catastrophic injury that results from a second blow to the head that immediately follows a concussive injury – often undiagnosed or an injury that was previously diagnosed but not fully healed. The second injury to an already damaged brain results in catastrophic swelling within the brain often incompatible with survival. Scottish boxer Mike Trowell died of a severe brain injury occurring in a sanctioned boxing match in Glasgow, Scotland on September 29.
Essentially, “second impact syndrome” or SIS results from the brain’s inability to autoregulate cerebral perfusion pressure and swelling as a result of repeated cerebral trauma. This leaves an athlete gravely injured unless immediate neurosurgical intervention can be provided (Bey & Ostick, 2009). Sadly, even with the best care many patients with SIS succumb to their injuries within a few minutes. Most believe that concussions create a metabolic crisis in the brain that results in a gross change in cerebral efficiency – an inability to match the external cerebral energy demand – especially sporting activity at the elite level.
In general, if the brain fully heals an athlete is at no greater risk of concussion than someone who has never sustained a concussion. However, when an athlete returns to play before he or she is fully healed they are at high risk for a second or third concussion and at risk for SIS. It is well know that there is a cumulative effect of injury to the brain with repeated trauma. In fact, repeated trauma results in a significant reduction in brain volume that can seriously reduce information processing speed and other neurocognitive functions according to a study in the British Journal of Sports Medicine in 2015. The greater number of fights resulting in more blows to the head has a significant impact on speed of processing. Certainly a well established link between repeated head trauma and dementia, depression, and other signs of neurocognitive decline has been found in U.S. football players.
Boxer fatally injured with second impact that was sustained in a fight in Scotland recently. Scottish Boxer Mike Towell was critically injured on September 30, 2016 during a fight with Dale Evans in Glasgow, Scotland. According to the BBC, Towell was knocked to the mat in the first round of a 10 round bout. He was given a standing 8 count and continued the fight. Some said he dominated the next two rounds when finally in the fifth round he was again knocked down and the fight was ended. He was transported to the trauma center in Glasgow ultimately being placed on life support. He lived 12 hours once the decision had been made to terminate life support. His partner Chloe Ross reported that Towell had been experiencing headaches in the weeks prior to the fight that were attributed to stress. Medical authorities may not have allowed Towell to fight had the recent history been known. Towell may have been highly vulnerable to concussion as a result of his boxing history and unique neurocognitive underpinning. So when he stayed in the fight he unknowingly put himself at risk for lethal injury.

WESTBOROUGH, MA June 6, 2016 The Bike of the week is drawn by a 86-year old man who is undergoing inpatient rehabilitation for an acquired brain injury and stroke. Actually I rarely publish the drawings made by patients I see unless I am going through a dry spell of interesting clocks. The man who drew this bicycle was independent prior to a fall and driving. In this case, there was a a fall 2 months ago – in April 2016 from which he largely recovered. He underwent lab studies and a C-T scan of his brain being diagnosed with subdural hematoma (SDH). The C-T scan revealed a collection of blood in the frontal part of his brain known as a subdural hematoma (SDH) often associated with brain trauma from a fall or motor vehicle crash. The patient in this case had fallen in his bathroom. He had been prescribed a blood thinner and his atrial fibrillation which was stopped. These levels were supratherapeutic – too high making him at high risk for bleeding – in this case in his brain. He was taken off the blood thinner in the weeks following the traumatic injury to allow the bleeding in his brain to be controlled. In late May, 2016, he was found at home to be slurring his words and demonstrating right hand weakness. He was rushed to Cape Cod Hospital and diagnosed with a left MCA ischemic stroke and he was treated conservatively.
Bleeding on the brain is a life threatening condition that will eventually result in herniation of brain tissue and death unless it is controlled. Trauma can lead to edema or swelling of brain tissue. In many cases, neurosurgery is required to remove subdural blood allowing space in the skull for the brain to swell as much as needed to recover. In some rare cases, the part of the skull is actually removed to allow for brain swelling. By removing a portion of the skull the brain tissue does not efface ipsilateral tissue or cause herniation by crowding out other viable brain tissue.
WESTBOROUGH, MA March 23, 2016 Here is a new clock drawn by a 85-year old male who is undergoing acute rehabilitation here is Westborough. As you can see from the measuring tape it is about 23 mm in size. It is just a bit over 1 inch in size. Although somewhat subjective, I would call this an example of micrographia. In general micrographic drawing refers to constructions and writing that are well below the expected size – especially when the patient is copying a design and produces a tiny drawing – micrographic in size. It is associated with lesions of the basal ganglia or neurodegeneration in the midbrain and is often seen in patients with Parkinson’s Disease. Some might argue that micrographia results from diminished frontal-executive functioning. This explanation is plausible to me but must include the system of attention as well. The patient who drew this clock needed two hands to craft some of his work by using his non-dominant left hand to steady the right as he wrote or drew. He had sustained a cardiac arrest and was successfully resuscitated. This man is not diagnosed with Parkinson’s.
I have added a second clock of the week also an example of micrographia. This clock was drawn by a 54-year old woman undergoing rehabilitation for a liver transplant. She
had had a long history of alcohol dependence resulting in damage to her liver. A transplant was undertaken in February 2016. Her drawing of 19 mm is only 3/4 inch in size. I use a mechanical pencil to be sure and get as much detail in the drawings as possible. Patients undergoing liver transplantation require weeks of rehabilitation due to the stress on the body this procedure instills. Below I have added another example drawn by the woman who is receiving treatment following a liver transplant.
The Luria patterns is a test of set switching – thought to be a frontal lobe function. This requires both attention to detail and the capacity to change the shape and angle of each character. Some people fail to appreciate that the pattern is only 2 shapes – flat & pointed – repeated over and over. I hope these drawings are of interest to those in training and or those with years of training in neuropsychology. I enjoy receiving the occasional clock drawing or some other construction of interest. Please do not hesitate to send your interesting clocks along with patient information and your interpretation.
