Accelerator/healthcare innovator StartupHealth’s ongoing series Startup Health Now! (#94) interviews Israeli entrepreneur Nathan Intrator, founder of Neurosteer, on developing new applications for brain monitoring in TBI cases, the impact home monitoring will have on patients and Israel’s burgeoning digital health scene. Highlights from the 18 minute video from this past June at Wearable Tech + Digital Health Conference, New York, NY include applications to monitor those who are minimally conscious to assist doctors in treatment; how data from remote patient home monitoring can detect early stage problems so that doctors can take proactive care, reducing cost and disruption; and Israel’s digital health ‘corridors’.

Possible early detection test for chronic traumatic encephalopathy (CTE)
A research study published today in the Proceedings of the National Academy of Sciences (US) presents the results of screening 14 retired professional American football players with suspected CTE. Using a tau-sensitive brain imaging agent, [F-18]FDDNP, the California and Illinois-based researchers were able to detect the abnormal accumulation of tau and other proteins, in the distinct CTE pattern, in the brains of living subjects who had received, during their playing careers, multiple concussions and head trauma. Of the 14, one had been diagnosed with dementia, 12 with mild cognitive impairment and one with no symptoms. Previous studies, such as Robert Stern, MD‘s pathfinding research at Boston University and for the NFL (see below), have been primarily post-mortem on brains donated for research, although Dr Stern’s last presentation at NYC MedTech and Inga Koerte, MD of the Ludwig-Maximilians-Universität München (LMU) have also used brain scan information on live subjects in their studies.
Where this differs is that the imaging agent injected binds to the tau (more…)
‘Brain Games’ on preventing, diagnosing sub-concussive brain trauma
Tuesday 13 May, presented at NYC MedTech-the NYC Medical Technology Forum, at Troutman Sanders LLP, Chrysler Building, New York City
In a packed (agenda and attendees) two hour evening meeting, three presenters detailed the latest research on the clinical signs of chronic traumatic encephalopathy (CTE), along with new technologies for detecting it as it happens and diagnosing it plus monitoring recovery: Robert Stern, PhD, professor of neurology and neurosurgery at the Boston University School of Medicine and a leading clinical researcher on CTE (as our long-time readers know) ; Isaiah Kacyvenski, head of the sports segment of electronics designer MC10 which developed the Checklight head impact indicator for Reebok; and Uzma Samadani, MD, PhD, co-founder of Oculogica which presented at ELabNYC a few weeks ago.
Dr. Stern’s presentation reviewed his clinical work with primarily NFL players in how CTE manifests in both behavior patterns and the brain. His focus remains on sub-concussive trauma, the ‘bottom of the iceberg’ in his analogy, and its cumulative, long-term effects. Repetitive brain trauma–neuronal shearing which is produced by linear, lateral and rotational forces to the head–produce a cascade of brain changes leading to destruction of brain tissues that show as dark patches on post-mortem samples and scans. These differ from Alzheimer’s disease in the abundance of tau protein distributed fairly early in life around the brain’s blood vessels and in the depths of the cortical sulci, where Alzheimer’s signature beta amyloid does not locate. Dr. Stern’s research also incorporates the behavioral changes that precede diagnosis: the emotional ‘short fuse’, the difficulty in memory, accidents, suicide, drastic changes in behavior and impulse control. There are many examples of degeneration and early death among players [TTA 6 Dec 12 which also refers to Dr. Stern’s research published in Brain; also see TTA 5 June 2013 on his German Center presentation which has additional background on his and his team’s research.]
In addition to the work he has done relating to (American) football (he is on the NFL Players Association brain injury committee and his research was instrumental in the PA’s lawsuit against the NFL), he studies other contact sports such as hockey (brain injury clusters (more…)
