Brain imaging has made surprisingly remarkable progress since the early, and now historic days, of invasive radiology, which has now been replaced with a number of spectacularly precise techniques: structural (CT Scan, MRI) and functional (PET, SPECT) imaging, direct imaging during neurosurgery, EEG and its computer-assisted derivatives, and transcerebral ultrasonography. We present five cases with two alleged autisms, a cerebral malaria, a panic disorder and to Parkinson disease with a depressive component. Using modern imaging methods the following respective diagnoses were arrived at: a left temporal cyst, a Sanfilippo mucopolysaccharidosis, a septum lucidum agenesis, a right temporal cyst, and a pituitary adenoma. These cases illustrate the scientific, emotional and philosophical impact, on physicians, and patients alike, of modern imaging technology. Neuroradiology, biochemistry and surgical imaging require a multi disciplinary approach and a perfect knowledge of psychiatric semeiology. In addition, they stimulate us to carefully reassess our sociocultural understanding to mental illness.

In humans, behavioral dopamine supersensitivity occurs in schizophrenia and in Parkinson's disease. In animals, behavioral dopamine supersensitivity is consistently associated with increased dopamine D2(High) receptors in homogenized striata in vitro. Because D2(High) receptors have not yet been detected in intact cells, we used [(3)H]domperidone to detect D2(High) sites in intact rat anterior pituitary adenoma culture cells. Although [(3)H]raclopride and [(3)H]spiperone did not detect D2(High) receptors in intact cells or in rat fresh striatal slices, [(3)H]domperidone readily detected D2(High) receptors, warranting an in vivo search for D2(High) variations in human diseases.

(1) Pathological gambling and increased sexual activity can occur in patients taking dopaminergic drugs. Detailed case reports and small case series mention serious familial and social consequences. The frequency is poorly documented; (2) Most affected patients are being treated for Parkinson's disease, but cases have been reported among patients prescribed a dopamine agonist for restless legs syndrome or pituitary adenoma; (3) Patients treated with this type of drug, and their relatives, should be informed of these risks so that they can watch for changes in behaviour. If such disorders occur, it may be necessary to reduce the dose or to withdraw the drug or replace it with another medication.
