This is the most common form of delusional disorder. In this form, the affected person fears they are being stalked, spied upon, obstructed, poisoned, conspired against or harassed by other individuals or an organization.

In one study of patients with schizophrenia delusions, delusions of reference were the most common delusion type, followed closely by persecutory delusions. However, some studies find persecutory delusions are the most common type.

Types of delusions include persecutory, erotomanic , grandiose , jealous, somatic, and mixed/unspecific.
Delusions are common to several mental disorders and can be triggered by sleep disturbance and extreme stress, but they can also occur in physical conditions, including brain injury or tumor, drug addiction and alcoholism, and somatic illness.
Common somatic delusions are that the person is infested by insects or parasites, that he or she is emitting a foul odor, that parts of the body are not functioning, or that certain parts of the body are misshapen and ugly even in the absence of objective evidence.
