Researchers at a neuropsychiatric institute are debating the physiological origins of schizophrenia.
Professor Al-Asadi notes: "Our twin database shows a striking concordance rate for monozygotic twins compared to dizygotic twins, though it never reaches 100%. We also see specific candidate gene clusters."
Dr. Vance responds: "But we must look at the immediate biochemistry and neuroanatomy. Patients exhibiting severe auditory hallucinations show abnormal neural activation patterns on fMRI and altered dopamine activity, while those with severe avolition show structural abnormalities like enlarged ventricles."
