Final answer:
The Undifferentiated type of schizophrenia is the subtype that includes a mix of the various symptoms of schizophrenia without a predominant feature. It is managed with antipsychotic medications that block dopamine receptors and reduce dopamine activity to alleviate symptoms.
Step-by-step explanation:
The type of schizophrenia that encompasses the basic symptoms of schizophrenia, such as hallucinations, delusions, disorganized speech, disorganized behavior, and negative symptoms (like a flattened emotional state, loss of pleasure, and loss of basic drives), is the c) Undifferentiated type. This classification is given to individuals who experience symptoms that do not clearly fit into the other categories of schizophrenia, such as the Catatonic, Disorganized, or Paranoid types, and display a mix of the different symptoms of schizophrenia with no predominant feature.
The development of schizophrenia is thought to involve malfunctioning dopaminergic neurons and may also involve problems with glutamate signaling. Treatment for schizophrenia usually requires antipsychotic medications that work by blocking dopamine receptors and decreasing dopamine neurotransmission in the brain, helping alleviate some of the symptoms of the disease.
