According to recent data up to 80-90 per cent of patients with PTSD experience insomnia and 
comorbid sleeping disturbances. Patients with sleep disorders are in higher risk of functional 
disability. Also their existing PTSD symptoms may exacerbate insomnia. 
Current PTSD diagnosis often does not fully capture the severity of psychological harm that occurs 
with prolonged, repeated trauma, such as: changes in self-concept and adaptation skills, addictive 
behaviour, self-mutilation. 
ICD 11 identifies complex PTSD as a separate condition that includes PTSD with personality changes, 
though the DSM-V currently does not. 
This study among 100 patients with PTSD and complex PTSD is a part of other project about 
correlation of stress exposure, presence of PTSD symptoms and inflammatory markers connected 
with some somatic diseases. 
Diagnosis of complex PTSD based on results of „International Trauma Questionnaire“. 
Insomnia symptoms measured by: „Insomnia Severity Index“. 
Reliving the trauma through flash backs and nightmares may lead to hyper-arousal , avoiding going to 
bed and worsening insomnia symptoms. 
The aim of our study is to compare and identify differences between insomnia symptoms among 
these two conditions, and to better understand complex PTSD, still often misdiagnosed as personality 
disorder, or unrecognized
