Somehow the same nurses, physicians, administrators and legal ombudsmen who prevented the study of the ventricular fluid of a patient with senile dementia, or obesity, or depression, or schizophrenia, because of the risks, will encourage diagnostic tests and therapy for patients with epilepsy that are far more destructive and immutable than the measurement and manipulation of hormones in the ventricle.
Patients with uncontrolled epilepsy have an evaluation that usually begins with electrical studies of the surface of the brain. …A hole is drilled in the skull, and electrical measurements made from within the depths of the brain. A large flap of the skull is then lifted up, electrodes placed on the surface of the brain, and the flap sewn back into place so that more electrical studies can be done. The risks... are far greater than those associated with the ventricular taps needed for hormone studies. …If the team of doctors.. can help... areas of the brain that are sending 'bad' signals would be identified and removed... large portions of the brain might be taken away.
Despite the evidence that ventricular hormones do not make their way out of the ventricle, the presence of large ventricles in many schizophrenic patients, and the ability of two-dimensional gels to provide a profile of peptides in the ventricle, not a single catheter has been placed into the ventricle of a schizophrenic patient to measure the peptides in the ventricle. ...There is no animal model for this disease, the answer can only come from human studies.
Animal experiments have confirmed the necessity of delivering hormones into the ventricle: the powerful hormone endorphin does not change behaviour if it is given intravenously; vasopressin will improve memory in animals only if it given into the ventricles; insulin given through the bloodstream does not control appetite but it is the best hormone for such control if given into the brain; and bombesin... only stops stomach ulceration if given into the brain.
