Schizophrenia, although it runs in families, is not a mutation, in the sense of something that has happened in a particular generation. It has been common throughout recorded history (although we used to call people who heard voices mystics, holy men or prophets).
Schizophrenia is caused by imbalances in brain chemistry, possibly by physical brain abnormalities in some rare cases, and occasionally may be either caused or triggered by physical or emotional trauma. Normal onset is in the late teens or early 20's, and it often self-ameliorates in late middle-age -- although by no means always.
Schizophrenia is related to some genes, but it is not caused completely by a mutation of DNA.
There is no single known mutation (or even a group of mutations). Schizophrenia is a complicated mental disorder with no clearly defined cause, but it does have effective treatments (but nobody really understands how and why those treatments actually work).
There is no single type of mutation that causes Hemophilia A. It is not the type of mutation but rather the location of the mutation within the genetic code.
It is a mutation/
chromosomal mutation
Paranoid schizophrenia is a disease of the brain.
Yes, schizophrenia is a type of psychosis. Psychosis is an abnormality in perception or expression of reality. Schizophrenia is a subtype of this.
Yes. People with Type I schizophrenia have mostly positive symptoms, such as delusions and hallucinations. People with Type II schizophrenia have mostly negative symptoms, such as withdrawing from others and flat affect.
catatonic schizophrenia
That is paranoid schizophrenia.
Catatonic schizophrenia is probably the most severe type. This type of schizophrenia can prevent someone from moving for days and from functioning normally at all. With the other types of schizophrenia, at least some normal function exists.
One type of dwarfism that is a point mutation is achondroplasia.
Yes, in my opinion, narcissism is a type of schizophrenia.
