Intrusive Vs Impulsive Thoughts

Intrusive thoughts are often unwanted ideas or distressing thoughts or images. They appear in our minds either randomly or as a consequence of a specific trigger.

Intrusive thoughts can be disturbing and can be signs of anxiety or distress or lead to mental health problems. In particular, intrusive thoughts have been associated with mental health conditions like obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), anxiety disorders and also eating disorders.

Intrusive thoughts can be related to a wide range of themes such as violence, sexuality or religion.

Impulsive thoughts refer to a sudden or strong urge to do something without considering the consequences.
