Post traumatic stress disorder (PTSD) is experienced by people who had undergone various traumatic events like tsunami, hurricanes, rape etc.

People suffer from recurrences of these bad memories which are intense //and painful and eventually cause a lot of disturbance in one’s life. Hence researchers have come up with a pill that could erase all the bad memories or atleast reduce the pain.

Psychiatrist Hilary Klein has witnessed a lot of cases who later go on to develop PTSD. This problem was first seen in Vietnam War veterans. But the good news is that only 24% of the victims suffer from PTSD.

The main symptoms are physical symptoms, memories, flashbacks etc. The scientific explanation that can be given to this PTSD is that the brain does not function properly after the traumatic event which results in the excess stress hormone causing to store these memories in a alternate mode rather than the normal ones.

Drugs to prevent the excess production of stress hormones can prevent the storage of these memories. Some doctors deliberately trigger the old memories and give medications to suppress them in order to treat the PTSD. The initial study was conducted on 19 individuals but there is a necessity to increase the sample size.

The government spends $4 billion a year to treat this kind of illness experienced by the American troops returning from Iraq and Afghanistan.

James McGaugh, director of the Center for the Neurobiology of Learning and Memory at the University of California at Irvine and his colleague, Larry Cahill, studied how memory formation occurs.

Then they said that memories form slowly over a period of time. During stress the body releases adrenalin and other hormones and will facilitate in the storing of these memories in the brain. But Propranolol can prevent the storage of memories as t is a beta blocker and prevents the release of various hormones.
