    Unlike in Alzheimer's Disease, neurofibrillary tangles in athletes with CTE tend to accumulate perivascularly within the superficial neocortical layers. It is interesting to note that TAU pathology in CTE is partially and extensively distributed, possible related to multi-directional mechanical force from physical trauma (McKee et al, 2009; Neuropath Exp Neurol 68, 709-35.) It is theorized that accumulation of hyperphosphor is related to a protein that is thought to result in development of CTE and associated neurobehavioral disturbances.

    The recent editors of Myers on Evidence of Interpersonal Violence (Myers 2016) notes that the most well-known of psychological instruments to assess suggestibility is the Gudjohnson Suggestibility Scales (GSS). The GSS is utilized by psychologists to evaluate whether defendant's confessions were voluntary. The author notes that it is doubtful that these instruments are sufficiently reliable for use in legal proceedings. It is noted that in Shanklin, 379 111 Dec 211 the trial judge did not err in subjecting the GSS to a Frye Henry.

    The author recently had a chapter accepted for publication on Methodology for Conducting Bonding Studies in Child Custody Evaluations (CCE). This chapter was written in response to the requests of many psychologists over the years who wanted guidance in procedures for conducting bonding studies. Many psychologists conduct bonding studies with cursory observations of parent and child. There is no application of an objective scoring system or any methods that can be replicated by other CCE Evaluators. This is essential in science.

    This week marked the enshrinement of Junior Seau in the NFL Hall of Fame. Junior was an outstanding linebacker for USC who went onto great accomplishments in the NFL. However, all was not well. The effects of domestic violence, substance abuse and gambling difficulties; as reported on ESPN's Outside the Lines, took the toll on Junior. He repeatedly complained to a friend who was a fellow player and suffered from headaches, how he too, suffered for years from headaches. ESPN noted that he was reported to have been diagnosed with chronic traumatic encephalopathy, a neuro-degenerative disease that can lead to dementia, memory loss and depression. Gina Seau reported that Junior's disease was associated with head-to-head collisions caused from 20 years of playing in the NFL. This scenario affected his ability to think logically.

    Prosecutors and law enforcement are frequently confronted with situations wherein children have been traumatized and/or injured. These injuries have resulted in disabilities which affect the child’s ability to understand questions as well as express answers to questions.
