|Popping into your mind|
Schizophrenia means a splitting of mental functions. It is a mental disorder often characterized by abnormal social behavior and failure to recognize what is real. Common symptoms include false beliefs, auditory hallucinations, confused or unclear thinking, inactivity, and reduced social engagement and emotional expression.
Individuals with schizophrenia may experience hallucinations (most reported are hearing voices), delusions (often bizarre or persecutory in nature, hence the term "paranoid schizophrenic"), and disorganized thinking and speech. The last may range from loss of train of thought (something called thought blocking), to sentences only loosely connected in meaning (tangentiality), to speech that is not understandable 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. People with schizophrenia often find facial emotion perception to be difficult In some cases patients can become catatonic, a trance-like state of abnormal motor activity in which the patient may stay frozen in the same position (often quite awkward and uncomfortable) for hours without moving or speaking, allow themselves to be posed by others (something called waxy flexibility), or in some cases enter an agitated motor frenzy. There is a considerable degree of heterogeneity in symptoms.
Schizophrenia is a major cause of disability, with active psychosis ranked as the third-most-disabling condition after quadriplegia and dementia and ahead of paraplegia and blindness. In a large, representative sample from a 1999 study, 12.8% of Americans believed that individuals with schizophrenia were "very likely" to do something violent against others, and 48.1% said that they were "somewhat likely" to. Over 74% said that people with schizophrenia were either "not very able" or "not able at all" to make decisions concerning their treatment, and 70.2% said the same of money management decisions.
 Self-medication and alternative medicine
A significant proportion of people with schizophrenia use cannabis and/or nicotine. It has been widely thought that cannabis and/or tobacco use is a form of self-medication, but there is some evidence that usage is actually causative of psychosis.
Religion, depending on how a patient views it, can be paralyzing and quite harmful, in that a patient may refuse treatment based on religious beliefs; in certain instances, one might believe that their delusions and hallucinations are actually a divine experience, and therefore deny any need for treatment. On the other hand, religion can also be a very valuable tool in coping with the disorder, especially for those who are active in a religious community. It has been shown that those with schizophrenia who suffer from religious delusions are more religious than those who do not suffer from these delusions.
In a 2014 cross-cultural study, researchers found that schizophrenics from different countries tended to have different types of hallucinations. In the United States, schizophrenics tended to hallucinate of "disembodied voices that hurl insults and make violent commands", whereas in India and Ghana, schizophrenics often reported "positive relationships with hallucinated voices that they recognize as those of family members or God."
 Political abuse of diagnosis
Sluggish schizophrenia was coined by Andrei Snezhnevsky, who as one of the chief architects of Soviet psychiatry broadened the symptoms of schizophrenia to include any pesky political dissidents and even those indirectly affected by alcoholism.
