Intrusive Thoughts - Associated Conditions

Associated Conditions

Intrusive thoughts are associated with OCD or obsessive-compulsive personality disorder, but may also occur with other conditions such as post-traumatic stress disorder, clinical depression, postpartum depression, and anxiety. One of these conditions is almost always present in people whose intrusive thoughts reach a clinical level of severity. A large study published in 2005 found that aggressive, sexual, and religious obsessions were broadly associated with comorbid anxiety disorders and depression. The intrusive thoughts that occur in a schizophrenic episode differ from the obsessional thoughts that occur with OCD or depression in that the intrusive thoughts of schizophrenics are false or delusional beliefs (i.e. held by the schizophrenic individual to be real and not doubted, as is typically the case with intrusive thoughts) .
