earlier i spoke to dr victoria williamson who�*s a lecturer at king�*s college london.t in gaza. people who have experienced traumatic and challenging events can develop mental—health problems like post—traumatic stress disorder or ptsd. they can also develop other difficulties like major depression and anxiety difficulties too. is ptsd a big risk for many of them? so, a number of people, after traumatic and challenging events can experience psychological difficulties and symptoms after trauma. i think it�*s really important to emphasise that experiencing psychological difficulties, symptoms, nightmares, difficulty with sleeping, things like that, is very normal after traumatic events and for most people those symptoms will come down after 6—8 weeks but for those people who find that their symptoms are very severe or they don�*t improve in a month, six weeks, post—trauma, that would be the time to start thinking about reaching out to a medical practitioner to get some sort of formal psychological support. can you tell us more about the kind of help they will need to cop
