What causes me to yell and scream and fight in my sleep during my dreams i have ptsd from vietnam service. i take prazosin but not helping?

Ptsd: Nightmares r a sx of ptsd prazosin sometimes helps-see a therapist who has experience with ptsd--as u probly know we don't have great treatment for ptsd.

Polysomnogram: The only way to obtain an accurate answer for this is to obain a polysomnogram. Although the subject is not well studied, we obtained polysomnograms on the majority of our combat ptsd patients in one program. A very high percentage had sleep disorders with only a moderate % having a rem sleep disorder. Ask your physician about a consultation with a sleep specialist. This is the starting point.
