What other types of schizophrenia are more common?

Question

I have read that the types not including the paranoid and delusionary features are pretty common? Can someone describe what a less critical form of schizophrenia is like? And when is typical onset and causal factors??

Answer 1

Paranoid schizophrenia is the most common type along with catatonic and disorganised. A person with paranoid schizophrenia will experience delusions and hallucinations (positive symptoms). A person with catatonic will have severe motor abilities such as unusual gestures or use of body language. Disorganised patients experience thought disturbances and are generally disorganised and not goal directed.

The least critical form would be undifferentiated. This is where the patient shows signs of schizophrenia but does not fit into any of the other categories.

A person may also be affected by secondary symptoms such as depression, as a result of having to cope with the disorder.

Men usually notice symptoms in their late teens or early twenties. Women are often affected later in their twenties and thirties.

Answer 2

Historically, schizophrenia in the West was classified into simple, catatonic, hebephrenic, and paranoid. The DSM now contains five sub-classifications of schizophrenia, the ICD-10 identifies 7:

(295.2/F20.2) catatonic type (prominent psychomotor disturbances are evident. Symptoms can include catatonic stupor and waxy flexibility).
(295.1/F20.1) disorganized type (where thought disorder and flat affect are present together),
(295.3/F20.0) paranoid type (where delusions and hallucinations are present but thought disorder, disorganized behavior, and affective flattening are absent),
(295.6/F20.5) residual type (where positive symptoms are present at a low intensity only) and
(295.9/F20.3) undifferentiated type (psychotic symptoms are present but the criteria for paranoid, disorganized, or catatonic types has not been met).
NB: Brackets indicate codes for DSM and ICD-10 diagnostic manuals, respectively. Some older classifications still use "Hebephrenic schizophrenia" instead of "Disorganized schizophrenia".
