Delusions are false beliefs that are strongly held despite evidence to the contrary. They can occur in various mental health conditions, such as schizophrenia or bipolar disorder. People experiencing delusions may believe they are being persecuted, have special powers, or are under constant surveillance, which can significantly impact their daily lives and relationships. These beliefs are not simply misunderstandings; they are deeply ingrained and resistant to reasoning or contrary evidence. Delusions can vary in severity and can lead to distress or dysfunction, making it important for individuals experiencing them to seek help from mental health professionals for proper diagnosis and treatment.
