Transcript of (PTSD)

Feeling the pressure: American troops in Afghanistan in 2007
Post-traumatic Stress disorder, or PTSD, is a brain affliction that is suffered by many people for many reasons.
The person’s response involves intense fear, helplessness, or horror.
The person has experienced, witnessed, or been confronted with an event or events that involve actual or threatened death or serious injury, or a threat to the physical integrity of oneself or others.
The Department of Veterans Affairs has released a new report on PTSD showing that since 9/11, nearly 30 percent of the 834,463 Iraq and Afghanistan War veterans treated at V.A. hospitals and clinics have been diagnosed with PTSD.
That means that 250,339 veterans have PTSD.
I have researched how PTSD changes the brain physically and chemically.
Overview and Criterion for (PTSD)
MRI testing in America has revealed startling differences in the brains of soldiers with combat stress - and could take us closer to being able to identify those at risk.
The yellow areas, Schuff explained, showed where the hippocampus, which plays major roles in short-term memory and emotions, had atrophies.
In 2008, UCSF senior scientist Norbert Schuff captured his colleague’s attention when he presented colorful brain images of the U.S. soldiers who had returned from Iraq and Afghanistan and were diagnosed with post-traumatic stress disorder.

The yellow areas, Schuff explained, showed where the hippocampus, which plays major roles in short-term memory and emotions, had atrophies.
The red swatches marked hyper fusion – increased blood flow – in the prefrontal cortex, the region responsible for conflict resolution and decision-making. Compared with a soldier without the affliction, the PTSD brain had lost 5 to 10 percent of its gray matter volume, indicating more neuron damage.
Changes in the Brain
(PTSD) in the Armed Forces.
Symptoms of PTSD are grouped into 3 Categories
Post Traumatic Stress Disorder (PTSD)

By: Lester F. Sanchez
There is no current lab test to detect (PTSD)
There are no laboratory tests to detect PTSD. To diagnose PTSD, a healthcare provider will consider the above symptoms together with history of trauma. He or she will likely also use psychological assessment tools to confirm the diagnosis and involve an appropriately trained specialist.
Acute PTSD - symptoms less than three months.
Chronic PTSD - symptoms more than three months.
Although symptoms usually begin within 3 months of exposure, a delayed onset is possible months or even years after the event has occurred.

Diagnosis and Types of (PTSD)
Last Remarks
"I don't think there are many people who believe PTSD will be solved by simply giving people a drug," says Wessely. "With soldiers, the only really effective way of preventing it would be to not go to war in the first place."
Through my research, I was able to confirm that Soldiers with (PTSD) had some sort of Alpha male aggressive behavior before joining the military and experiencing combat.

Compared with a soldier without affliction, the PTSD brain had lost 5 to 10 percent of its gray matter volume.
Those who have PTSD have also been found to have a smaller hippocampus. The hippocampus plays an important part in organizing a person’s memory and regulating their emotions.
Chemical changes in the Brain
Recurrent and intrusive distressing recollections of the event.
Sudden acting or feeling as if the traumatic event were recurring.
Efforts to avoid activities, places, people or situations that arouse recollection of the trauma.
Inability to recall an important aspect of the trauma (psychological amnesia).
Irritability or outburst of anger-irritability can progress to rage.
Hypervigilence- resembles frank paranoia.
There is a chemical flooding of the brain during a traumatic experience. These chemicals help the person to survive the event causing a flight or fight response.
PTSD will also elevate the levels of dopamine, causing some to become violent or paranoid. PTSD also lowers serotonin levels, which can trigger depression, anxiety, aggression, impulsivity and even suicidal behavior.
Individual Therapy.
Group Support (especially for Chronic PTSD).
Medications such as:
Lamotrigine; which is a mood stabilizer, and is also used for Bi-Polar disorder.
Flouxetine HCL; more commonly know as Prozac to increase levels of serotonin in the Brain.
And Trazodone; are prescribed for sleep disorders.
Because it affects many different parts of the brain in many ways, both physically and chemically, it is hard to treat medically. PTSD is treated with both therapy and or medication.
