Psychotic Disorders

Explanation : Nihilistic delusion- My head is missing , I have no body or I am dead

Explanation: A delusion is a false belief, Illusions are misperceptions of real stimuli. Hallucinations are sensory perceptions that occur in the absence of external stimuli

About one-third of those who develop an acute schizophrenic episode have a good outcome. One-third develop chronic, incapacitating schizophrenia, and the remainder largely recover after each episode but suffer relapses. Most affected patients cannot work or live independently. Schizophrenia is associated with suicide and up to 10% of patients take their own lives

Illusion is a false interpretation.

Cardiac arrhythmias
Antipsychotic medications cause prolongation of the QTc interval, which may be associated with ventricular tachycardia, torsades de pointes and sudden death. If this occurs, treatment should be reviewed, with careful electrocardiographic monitoring and treatment of serious arrhythmias if necessary.
