Essentially, no data are available on the contemporary population of invasive fluoroscopists, whose level and pattern of head exposure is unprecedented, although some anecdotal clusters of brain cancer have been recently described [ 39, 40].
It should be noted, however, that individual cases may begin to develop the clinical features of TES during their period of head impact exposure (for example, while still actively involved in a collision sport), especially older individuals or those who have been engaged in the high-exposure activity for many years.
The main objective of the PFBHS is to determine the relationships between measures of head trauma exposure, along with other potential modifiers, and changes in brain imaging and neurological/behavioral function over time.
Among possible variables under investigation by our group and other laboratories are the quantity or severity (or both) of the brain trauma, the initial age and overall duration of head impact exposure, lifestyle factors, and genetic susceptibility.
To quantify the magnitude, frequency, duration and distribution of head impact exposure in a women's rugby league competition.
A radiolucent vertical-cephalostat was designed to support and restrain sedated animal's body and head during exposure of images [ 5].
A radiolucent vertical-cephalostat was designed to support and restrain the animal's body and head during exposure of images; this was fabricated by the Electromechanical Technology Workshop at Otago University.
Therefore, it is possible to meet criteria for TES and yet have an idiopathic disorder or a situationally based condition that is unrelated to the earlier history of head impact exposure.
"We don't know if it's a specific age, we don't know if it's a cumulative number of years of exposure to head trauma, we don't know what combination of hits to the head set this disease in motion," Dr. Stern said.
As mentioned above, all of our measures of exposure to head trauma are indirect and may not truly reflect the actual degree of head trauma each subject experienced.
