Wheezy,
You sound more mature than rest of the trolls/4th year kids on this forum..
Tell us more about yourself and your background.
Cortical stimulation and intrathecal infusion of certain medications are currently at initial stages of research.. You know many drugs simply cannot pass the blood brain barrier so I am very dubious if there will ever be medications suited for neurological treatment. I know of a neurosurgery resident at UCSF who will publish a paper (hopefully that should end up in Nature or Science) on invasive treatment of AD within the next year.
Neurology is full of people who want to make easy money by doing EMGs or monitoring epilepsy or migraine all their lives. Take an example of Trigeminal neuralgia. For a hundred years neurologists could not come up with a drug to treat the condition. Now Neurosurgeons are doing thousands of microvascular decompressions every year and treating this disease. Isnt that a failure of the Neurologist? Same goes for PD and deep brain stimulation.
Neurologists have to think invasively.. they have to create interventions and be genuinely interested in 'treatment'. Otherwise Neurosurgeons will continue to dominate the direction of thought and research on disorders of the central nervous system. From researching on viral vectors to treat CNS disorders, to using endovascular and endoscopic treatment of various CNS conditions, neurosurgeons are eons ahead of you guys.
And finally, unlike neurosurgery, there are very few neurologists who are GENUINELY interested in research.
