Persecutory delusions are a delusional condition in which the affected person believes they are being persecuted. Specifically, they have been defined as containing two central elements:[1]
  1. The individual thinks that harm is occurring, or is going to occur.
  2. The individual thinks that the perceived persecutor has the intention to cause harm.
According to the DSM-IV-TR, persecutory delusions are the most common form of delusions in schizophrenia, where the person believes "he or she is being tormented, followed, tricked, spied on, or ridiculed."[2] In the DSM-IV-TR, persecutory delusions are the main feature of the persecutory type of delusional disorder.

Paranoia /ˌpærəˈnɔɪə/ (adjective: paranoid /ˈpærənɔɪd/) is a thought process believed to be heavily influenced by anxiety or fear, often to the point of irrationality and delusion. Paranoid thinking typically includes persecutory beliefs, or beliefs of conspiracyconcerning a perceived threat towards oneself. (e.g. "Everyone is out to get me.")

Grandiose delusions (GD) or delusions of grandeur is principally a subtype of delusional disorder that occurs in patients suffering from a wide range of mental illnesses, including two-thirds of patients in manic state of bipolar disorder, half of those with schizophrenia and a substantial portion of those with substance abuse disorders.[1][2] GDs are characterized by fantastical beliefs that one is famous, omnipotent, wealthy, or otherwise very powerful. The delusions are generally fantastic and typically have a supernatural, science-fictional, or religious theme. There is a relative lack of research into GD, in comparison to persecutory delusions and auditory hallucinations. About 10% of healthy people experience grandiose thoughts but do not meet full criteria for a diagnosis of GD....


Symptoms

According to the DSM-IV-TR diagnostic criteria for delusional disorder, grandiose-type symptoms include grossly exaggerated belief of:
  • self-worth
  • power[5]
  • knowledge
  • identity
  • exceptional relationship to a divinity or famous person

Accounts of delusion

There are two alternative accounts for getting grandiose delusions:[9]
  • Delusion-as-defense account: defense of the mind against lower self-esteem and depression
  • Emotion-consistent account: result of exaggerated emotions.
Diagnosis[edit source | editbeta]

Patients with a wide range of mental disorders which disturb brain function experience different kinds of delusions, including grandiose delusions.[12] Grandiose delusions usually occur in patients with syndromes associated with secondary mania, such as Huntington's disease,[13] Parkinson's disease,[14] and Wilson's disease.[15] Secondary mania has also been caused by substances such aslevodopa and isoniazid which modify the monoaminergic neurotransmitter function.[16] Vitamin B12 deficiency,[17] uremia,[18]hyperthyroidism[19] as well as the carcinoid syndrome[20] have been found to cause secondary mania, and thus grandiose delusions.
In diagnosing delusions, the MacArthur-Maudsley Assessment of Delusions Schedule is used to assess the patient.

Schizophrenia (/ˌskɪtsɵˈfrɛniə/ or /ˌskɪtsɵˈfrniə/) is a mental disorder characterized by a breakdown of thought processes and by a deficit of typical emotional responses.[1]Common symptoms include auditory hallucinations, paranoid or bizarre delusions, ordisorganized speech and thinking, and it is accompanied by significant social or occupational dysfunction. The onset of symptoms typically occurs in young adulthood, with a global lifetime prevalence of about 0.3–0.7%.[2] Diagnosis is based on observed behavior and the patient's reported experiences.
Genetics, early environment, neurobiology, and psychological and social processes appear to be important contributory factors; some recreational and prescription drugs appear to cause or worsen symptoms. ....

Self-portrait of a person with schizophrenia, representing that individual's perception of the distorted experience of reality in the disorder
A person diagnosed with schizophrenia may experience hallucinations (most reported arehearing voices), delusions (often bizarre or persecutory in nature), and disorganized thinking and speech. The latter may range from loss of train of thought, to sentences only loosely connected in meaning, to incoherence known as word salad in severe cases. Social withdrawal, sloppiness of dress and hygiene, and loss of motivation and judgment are all common in schizophrenia.[8] There is often an observable pattern of emotional difficulty, for example lack of responsiveness.[9] Impairment in social cognition is associated with schizophrenia,[10] as are symptoms of paranoia; social isolation commonly occurs.[11]Difficulties in working and long-term memory, attention, executive functioning, and speed ofprocessing also commonly occur.[2] In one uncommon subtype, the person may be largely mute, remain motionless in bizarre postures, or exhibit purposeless agitation, all signs ofcatatonia.[12] About 30% to 50% of people with schizophrenia do not have insight, in other words, they do not accept their condition or its treatment.[13] Treatment may have some effect.[14] Facial emotion perception is often impaired in people with schizophrenia.

Bipolar disorder, also known as bipolar affective disorder, manic-depressive disorder, or manic depression, is a mental illnessclassified by psychiatrists as a mood disorder. Individuals with bipolar disorder experience episodes of a frenzied mood known as maniaalternating with episodes of depression.
Mania can occur with different levels of severity. At milder levels of mania, or "hypomania", individuals appear energetic, excitable, and may in fact be highly productive. As mania becomes more severe, individuals begin to behave erratically and impulsively, often making poor decisions due to unrealistic ideas about the future, and may have great difficulty with sleep. At the most severe level, individuals can experience very distorted beliefs about the world known as psychosis.
Individuals who experience manic episodes also commonly experience depressive episodes; some experience a mixed state in which features of both mania and depression are present at the same time. Manic and depressive episodes last from a few days to several months...
Signs and symptoms

In bipolar disorder, people experience abnormally elevated (manic or hypomanic) mood states which interfere with the functions of ordinary life. Many people with bipolar disorder also experience periods of depressed mood, but this is not universal. There is no simple physiological test to confirm the disorder. Diagnosing bipolar disorder is often difficult, even for mental health professionals. In particular, it can be difficult to distinguish depression caused by bipolar disorder from pure unipolar depression.
The younger the age of onset, the more likely the first few episodes are to be depressive.[1] Because a bipolar diagnosis requires a manic or hypomanic episode, many patients are initially diagnosed and treated as having major depression...
Manic episodes

Mania is the defining feature of bipolar disorder. Mania is a distinct period of elevated or irritable mood, which can take the form of euphoria, and lasts for at least a week (less if hospitalization is required).[3] People with mania commonly experience an increase in energy and a decreased need for sleep, with many often getting as little as three or four hours of sleep per night. Some can go days without sleeping.[4] A manic person may exhibit pressured speech, with thoughts experienced as racing.[5] Attention span is low, and a person in a manic state may be easily distracted. Judgment may be impaired, and sufferers may go on spending sprees or engage in risky behavior that is not normal for them. They may indulge in substance abuse, particularly alcohol or other depressants, cocaine or other stimulants, or sleeping pills. Their behavior may become aggressive, intolerant, or intrusive. They may feel out of control or unstoppable, or as if they have been "chosen" and are "on a special mission", or have other grandiose or delusional ideas. Sexual drive may increase. At more extreme levels, a person in a manic state can experience psychosis, or a break with reality, where thinking is affected along with mood.[6] This can occasionally lead to violent behaviors.[7] Some people in a manic state experience severe anxietyand are irritable (to the point of rage), while others are euphoric and grandiose. The severity of manic symptoms can be measured by rating scales such as the Altman Self-Rating Mania Scale[8] and clinician-based Young Mania Rating Scale.[9][10]
The onset of a manic episode is often foreshadowed by sleep disturbances. Mood changes, psychomotor and appetite changes, and an increase in anxiety can also occur up to three weeks before a manic episode develops.....
