We have to remain humble about our understanding of the brain, because even our most powerful tools remain pretty blunt instruments for decoding the brain. In fact, we still do not know how to decipher the basic language of how the brain works.

Sometimes, patients with serious mental illness, just as with other serious medical illnesses, require hospitalization. In the absence of available public or private hospital beds, there are few options.

For bipolar in adults, I think there's pretty good agreement about what this looks like. For bipolar in children, there is some considerable debate about where are the boundaries.

During the summer months of my high-school years, I befriended Dr. Robert Kough, a physician who cared for members of my family.

Science in textbooks is not fun. But if you start doing science yourself, you will find delight.
