Schizophrenia is a form of psychosis. All psychosis involves losing touch with reality. In schizophrenia this is a chronic concition which often involves hearing voices which disparage the schizophrenic or command him to do something. There are many types of psychoses. Refer to the DSM IV for more details.
Schizophrenia has a genetic basis for psychotic symptoms. Mental illness runs in families. However, there are other reasons for why someone can become psychotic. The most common is drug-induced, and psychiatrists will say that there is no way to know for sure if the patient's psychosis is caused by drugs or if they have a diagnosis of schizophrenia. That's where family history is helpful, as well of drug-testing. Some people can have a psychotic episode from taking certain prescription drugs. The difference with schizophrenia is that it will not go away when the person stops taking drugs, although some drugs do have residual effects that can last for some time. The most common forms of psychosis are auditory hallucinations, (hearing voices in one's head), paranoia and delusions. Schizophrenics can also have what are called "negative symptoms", meaning that they isolate, avoiding all social interactions, stop being interested in previous things they once enjoyed, fail to keep up with daily hygiene. They may have what is called "inappropriate affect", responding to things in the opposite manner of most people, such as laughing at something serious.
The mental health community doesn't classify disorders as "neurotic" or "psychotic" anymore, although psychosis is sometimes a component of major mental disorders.
Historically, the concepts related to the psychiatrist's (or other mental health professional's) assessment of a person's degree of contact with "reality," which was sometimes broadly interpreted to mean "conventional beliefs," as well as delusions, hallucinations, unwarranted paranoia, and moderate-to-severe forms of what are now called personality disorders.
Neurosis was considered a lesser form of mental illness characterized by a long-standing pattern of obsessive or anxious thoughts and behavior. Woody Allen is a classic example of someone who would be considered neurotic. In fact, most people who entered therapy for mild-to-moderate adjustment problems, interpersonal difficulties, and other problems of living, would be classified as neurotic even if their difficulties were transient or developmentally appropriate. So-called "neurotics" were sometimes referred to as "the worried well."
"Neurotic" is a subjective, ill-defined and archaic term that has no real meaning in modern diagnostic schemes.
Psychosis, or psycotic illness, is an illness in which the patient loses contact with reality, and usually requires hospitalization with intensive treatment. A non-psychotic illness can be depression, OCD (obsessive compulsive disorder), senility, agorophobia, etc., and is much more easily treated and/or controlled.
A chief difference is that depersonalization is usually externally focused, and derealization is usually internally focused; or, the first psychotic and the second neurotic.
Psychotic disorders involve a loss of touch with reality, leading to hallucinations or delusions. Neurotic disorders involve distressing emotional symptoms like anxiety or depression that do not involve losing touch with reality.

The difference between hospital nursing and community nursing is that the latter one stresses prevention methods for patients. Community nursing aims to lower the risk of patients needed hospital treatments, while nurses at hospitals deal with illnesses usually after they have progressed.
Psychotic behavior involves a loss of touch with reality, such as experiencing hallucinations or delusions. Neurotic behavior involves excessive anxiety, distress, or emotional instability. Psychotic behavior is more severe and may require medical intervention, while neurotic behavior is typically less severe and may be managed through therapy or coping strategies.
