'Each is worsening,' nan 42-year-old wrote earlier shooting himself successful nan bosom and leaving his encephalon to beryllium analyzed by nan Department of Defense - which has since discovered an different shape of harm it believes whitethorn person been caused by his ain weapons.
Now, Metcalf's wife, Jamie, says she sees his abrupt decease arsenic a measurement to tie attraction to nan problem affecting Special Operators.

Lt. David Metcalf took his ain life wrong a car shed astatine his North Carolina location successful 2019, leaving a missive down describing encephalon issues he had been facing
At slightest a twelve Navy SEALS person died by termination complete nan past decade - either while successful nan subject aliases soon aft leaving.
A reappraisal of their deaths has since wished that they each had a number of factors successful common.
The mean property of nan deceased veterans is 43, and each was deployed to combat a number of times - but nary had been wounded by force fire, according to nan Times.
All of nan veterans besides spent years firing a scope of powerful weapons, jumping from airplanes, blowing unfastened doors pinch explosives, diving heavy underwater and learning hand-to-hand combat.
Around nan property of 40, astir each of them started to struggle pinch insomnia, headaches, representation and coordination problems, depression, disorder and sometimes rage.
Many were besides diagnosed pinch Post Traumatic Stress Disorder, but a Department of Defense study of 8 of nan soldiers recovered blast harm successful nan brains of each azygous one.

That encephalon harm apparently came from daze waves unleased by nan troops' ain triggers successful an array of weapons, studies suggest.
The power waves from a weapons blast surge done nan encephalon and bounce disconnected insubstantial boundaries for illustration an echo, according to nan Times.
For a fewer fractions of a millisecond, these waves create a vacuum that causes adjacent liquid successful nan encephalon to detonate into bubbles of vapor.
Those explosions are past powerful capable to rustle braincells apart.
At first, location whitethorn beryllium nary noticeable symptoms - but arsenic vulnerability continues, nan effects whitethorn turn worse, according to Dr. Daniel Daneshvar - nan main of encephalon wounded rehabilitation astatine Harvard Medical School.
He explained that brains tin often compensate for nan damage, until nan injuries accumulate to a captious constituent erstwhile 'people benignant of autumn disconnected a cliff.'

Petty Officer David Collins took his ain life successful March 2014
For Petty Officer David Collins, nan repeated vulnerability led to disorder successful nan years earlier he took his ain life.
Collins had spent 20 years moving arsenic a Navy SEAL, and was deployed to Afghanistan doubly and Iraq 3 times.
When he was not deployed, his woman said he was distant from location for hundreds of days each twelvemonth successful training.
Combat ne'er seemed to faze him, his woman Jennifer said, but toward nan extremity of his career, Collins started to debar societal gatherings, struggled to slumber and started making obsessive family schedules - becoming irritated erstwhile they were not followed.
Simple chores for illustration raking nan leaves started to confound him, Jennifer said, describing really we would locomotion retired nan doorway to spell to work, recognize he had forgotten his keys, spell backmost wrong to get them and hide why he returned.
His intelligence wellness past really started to return a move astatine nan property of 45.
He near nan Navy and started a civilian occupation school troops really to run mini drones, but 1 morning, Jennifer said he called her successful a panic from a activity trip, saying he forgot really to do his occupation and had not slept successful 4 days.

Collins would past spell connected to return his life successful March 2014.
When constabulary arrived astatine their Virginia Beach location to corroborate his death, Jennifer said she was 'adamant' that she wanted his encephalon donated to research.
'I wanted to effort to find immoderate answers,' she said.
That aid marked nan first for nan Department of Defense's Brain Tissue Repository successful Bethesda, Maryland - which had been group up 2 years anterior to analyse nan brains of deceased veterans for clues astir PTSD and traumatic encephalon injuries.
As researchers location pored complete Collins' brain, they noticed that astir everyplace that tissues of different density aliases stiffness met, location was a separator of scar tissue.
'For nan first time, we could really spot nan injury,' Dr. Daniel Perl said, noting: 'If you cognize what nan problem is, you tin commencement to creation solutions.'
The Pentagon says it has a 'moral responsibility to protect nan cognitive wellness and combat effectiveness of our teammates'
They would spell connected to announcement nan aforesaid shape successful six of nan 8 Navy SEALs who took their ain lives, arsenic Jennifer convinced much and much families to travel forward.
By nan clip Metcalf died successful 2019, encephalon donations had go somewhat communal for Special Operations troops.
So aft nan lieutenant died, Jamie decided to donate his encephalon to investigation arsenic well.
She has described really she noticed a abrupt diminution successful her hubby erstwhile he returned successful 2018 from his 5th deployment.
He had been a precocious achiever, was an enlisted SEAL sniper and taught martial arts to different SEALs. A fewer years earlier he died, Metcalf besides decided to prosecute a subject aesculapian career, became an serviceman and sailed done a training programme for expert assistants.
But he started to go confused and plagued by headaches, Jamie said, describing really he would put bedewed laundry successful nan dryer connected apical of barren clothes.
'It was truthful dissimilar him - he had ever been truthful organized,' she said.
'Now I cognize he was acrophobic location was thing happening successful his brain, but astatine nan time, I deliberation he tried to hide it.'
But researchers wished Metcalf and 1 different worker had a different type of harm successful nan aforesaid area of nan encephalon arsenic nan different SEALs.
Star-shaped helper cells successful their brains, called astrocytes, appeared to person been many times injured and grew into large, tangled masses that hardly functioned.
