Subject: "Neurological Symptoms Among US Diplomats in Cuba (Editorial)
Heads Up sequela of the damaging audiologic & ultrasound effects on the BBB (blood brain barrier) causes the fatigue/dementia, headache sydromes
"A Review of Current Ultrasound Exposure Limits
Research has shown that airborne ultrasound has the potential to cause nausea, fatigue, and headaches"
Recently, devices have become commercially available, which indirectly generate audible sound by initially generating ultrasound. The details of the method by which
audible sound is generated from ultrasound can be found in References
The potential use of these devices to act as focused sources in an active noise system was the impetus to conduct our review of the literature to find current recommendations for the exposure limits of airborne ultrasound impinging on the human ear
There is a general consensus amongst standards organizations on the exposure limits for ultrasound. The limits were derived by independent research groups who arrived at very similar findings for acceptable exposure limits [5]. The exceptions to the general consensus are the guidelines from the US Occupational Health and Safety Administration (OSHA) etc

Hemorrhage detection during focused-ultrasound induced blood-brain-barrier opening by using
susceptibility-weighted magnetic resonance imaging.
MEDLINE ABSTRACT
High-intensity focused ultrasound has been discovered to be able to locally and reversibly
increase the permeability of the blood-brain barrier (BBB), which can be detected using
magnetic resonance imaging (MRI)
Lab Results-
However, side effects such as microhemorrhage, erythrocyte extravasations or even extensive
hemorrhage may also occur

Dear
I hope this note finds You well
Keep up the good work
Sounds worse than the chicago/denver sleep deprivation, headaches, gas, tone scams &c
Possibly this neurological entity has to do with what is termed "psy-ops," the surreptitious sensory overload sociopathy which is described in the Literature
If they visited LMD's (Local Medical Doctors) there at Cuba, they probably would have been premeditatively misdiagnosed
Those who scam with such sociopathy would attempt to deny its existence
Best wishes always
Thank you for your assistance with this matter

FOR IMMEDIATE RELEASE: WEDNESDAY, FEBRUARY 14, 2018
The full study is available on the JAMA website and the following link can be embedded in your story:
http://jamanetwork.com/journals/jama/fullarticle/10.1001/jama.2018.1742
Bottom Line: Concussion-like symptoms were observed in U.S. government personnel in Cuba after they reported hearing intensely loud sounds in their homes and hotel rooms and feeling changes in air pressure caused by an unknown source. The symptoms were
consistent with brain injury although there was no history of head trauma.
Why The Research Is Interesting: In late 2016, U.S. government personnel in Havana, Cuba, visited the embassy medical unit after experiencing unusual sound and sensory phenomena and the onset of neurological symptoms. The U.S. Department of State convened
an expert panel in July 2017, which came to a consensus that the initial findings were most likely related to neurotrauma from a non-natural source and the department recommended further investigation of the symptoms. The University of Pennsylvania’s Center
for Brain Injury and Repair was selected to coordinate the evaluation, treatment and rehabilitation of these patients. This article in JAMA reports the preliminary findings.
Who and When: over 20 government personnel (11 women and 10 men) identified by the State Department and evaluated an average of 203 days following exposure to reported sound (described as “buzzing,” “grinding metal,” “piercing squeals”) and sensory phenomena
(described as pressure-like or vibrating and likened to air “baffling” inside a moving car with the windows partially rolled down)
What (Study Measures): Audible and sensory phenomena coming from a distinct direction but from an unknown source (exposure); descriptions of symptoms and personnel experience with rehabilitation and return to work (outcomes)
How (Study Design): This was a case series, which describes the clinical course or outcomes of a group of patients. Researchers cannot control for exposures or differences that could explain patient outcomes and they cannot prove a causal relationship.
Results:
Study Limitations: To protect patient privacy, certain details typically reported in a case series were omitted, including specifics about geography, the relationship between individuals and individual demographics.
Study Conclusions: The unique circumstances of these patients and the clinical manifestations detailed in this report raise concern about a new mechanism for possible acquired brain injury from an exposure of unknown origin.

Conclusions and Relevance-
In this preliminary report of a retrospective case series, persistent cognitive, vestibular, and oculomotor dysfunction, as well as sleep impairment and headaches, were observed among US government personnel in Havana, Cuba, associated with reports of
directional audible and/or sensory phenomena of unclear origin. These individuals appeared to have sustained injury to widespread brain networks without an associated history of head trauma

Neurological Manifestations Among US Government Personnel Reporting Directional Audible and Sensory Phenomena in Havana, Cuba
neurological manifestations associated with reports of audible and sensory phenomena among US government personnel in Havana, Cuba
Findings In this case series of 21 individuals exposed to directional audible and sensory phenomena, a constellation of acute and persistent signs and symptoms were identified, in the absence of an associated history of blunt head trauma. Following exposure,
patients experienced cognitive, vestibular, and oculomotor dysfunction, along with auditory symptoms, sleep abnormalities, and headache.
Meaning The unique circumstances of these patients and the consistency of the clinical manifestations raised concern for a novel mechanism of a possible acquired brain injury from a directional exposure of undetermined etiology.
Abstract
Importance From late 2016 through August 2017, US government personnel serving on diplomatic assignment in Havana, Cuba, reported neurological symptoms associated with exposure to auditory and sensory phenomena.
Objective To describe the neurological manifestations that followed exposure to an unknown energy source associated with auditory and sensory phenomena.
Design, Setting, and Participants Preliminary results from a retrospective case series of US government personnel in Havana, Cuba. Following reported exposure to auditory and sensory phenomena in their homes or hotel rooms, the individuals reported a
similar constellation of neurological symptoms resembling brain injury. These individuals were referred to an academic brain injury center for multidisciplinary evaluation and treatment.
Exposures Report of experiencing audible and sensory phenomena emanating from a distinct direction (directional phenomena) associated with an undetermined source, while serving on US government assignments in Havana, Cuba, since 2016.
Main Outcomes and Measures Descriptions of the exposures and symptoms were obtained from medical record review of multidisciplinary clinical interviews and examinations. Additional objective assessments included clinical tests of vestibular (dynamic and
static balance, vestibulo-ocular reflex testing, caloric testing), oculomotor (measurement of convergence, saccadic, and smooth pursuit eye movements), cognitive (comprehensive neuropsychological battery), and audiometric (pure tone and speech audiometry)
functioning. Neuroimaging was also obtained.
Results Of 24 individuals with suspected exposure identified by the US Department of State, 21 completed multidisciplinary evaluation an average of 203 days after exposure. Persistent symptoms (>3 months after exposure) were reported by these individuals
including cognitive (n?=?17, 81%), balance (n?=?15, 71%), visual (n?=?18, 86%), and auditory (n?=?15, 68%) dysfunction, sleep impairment (n?=?18, 86%), and headaches (n?=?16, 76%). Objective findings included cognitive (n?=?16, 76%), vestibular (n?=?17, 81%),
and oculomotor (n?=?15, 71%) abnormalities. Moderate to severe sensorineural hearing loss was identified in 3 individuals. Pharmacologic intervention was required for persistent sleep dysfunction (n?=?15, 71%) and headache (n?=?12, 57%). Fourteen individuals
(67%) were held from work at the time of multidisciplinary evaluation. Of those, 7 began graduated return to work with restrictions in place, home exercise programs, and higher-level work-focused cognitive rehabilitation.
Conclusions and Relevance In this preliminary report of a retrospective case series, persistent cognitive, vestibular, and oculomotor dysfunction, as well as sleep impairment and headaches, were observed among US government personnel in Havana, Cuba,
associated with reports of directional audible and/or sensory phenomena of unclear origin. These individuals appeared to have sustained injury to widespread brain networks without an associated history of head trauma.
Introduction
In late 2016, US government personnel serving in Havana, Cuba, began presenting to their embassy medical unit after experiencing unusual auditory and/or sensory stimuli of variable intensity and character, with associated onset of varied neurological manifestations.
Initial signs and symptoms pointed toward injury of the auditory system, leading to the establishment of a triage program at the University of Miami centered around otolaryngology evaluation. Eighty embassy community members underwent initial evaluation between
February and April 2017, and 16 individuals were identified with similar exposure history and a constellation of neurological signs and symptoms commonly seen following mild traumatic brain injury, also referred to as concussion.1 Exposures continued with
time and 8 additional individuals were identified who had similar findings. The US Department of State, Bureau of Medical Services, subsequently convened an expert panel in July 2017, which came to consensus that the triage findings were most likely related
to neurotrauma from a nonnatural source and recommended that further investigation into this novel cluster of findings was necessary
