(Editor’s Note: given the growing media attention to three apparently separate worlds -cognitive enhancement via drugs, brain fitness training software, computerized neurocognitive assessments-, I found it refreshing to see our co-founder Elkhonon Goldberg introduce the topic of cognotropic drugs with an integrative perspective in the much updated new edition of his classic book, now titled The New Executive Brain: Frontal Lobes In A Complex World. Below goes an excerpt).

For many neuropsychologists, like myself, science is a labor of love, but seeing patients is bread and butter. Traditionally, the clinical contribution of neuropsychology has been mostly diagnostic, with precious little to offer patients by way of treatment. Neuropsychology is not the only clinical discipline for years consigned to helpless voyeurism. Every discipline concerned with cognition shares this humbling predicament. A psychiatrist treating a schizophrenic patient or a depressed patient finds him- or herself in a similar position. There are ample pharmacological tools to treat the patient’s psychosis or mood, but very few to treat the patient’s cognition. Even though psychiatrists increasingly recognize that cognitive impairment is often more debilitating in their patients than psychosis or mood disorder, traditionally, very little direct effort has been aimed at improving cognition.

A neurologist treating a patient recovering from the effects of head injury does not fare much better. There are adequate means to control the patient’s seizures but not his or her cognitive changes, despite the fact that cognitive impairment is usually far more debilitating than an occasional seizure. Society has been so preoccupied with saving lives, treating hallucinations, controlling seizures, and lifting depression that cognition (memory, attention, planning, problem solving) has been largely ignored. Granted, various neuroleptics, anticonvulsants, antidepressants, sedatives, and stimulants do have an effect on cognition, but it is an ancillary effect of a drug designed to treat something else.

Alzheimer’s disease and other dementias have been society’s wake-up call. Here, in the most affluent country in the most affluent of times, human minds were succumbing to decay before human bodies, a sharp challenge to the tacit popular belief that the “body is frail but soul is forever.” This provided an impetus for the development of an entirely new class of drugs, which can be termed familially as “cognotropic.” Their primary and explicit purpose is to improve cognition.

Since medical and public preoccupation with dementia focuses on memory, most of the pharmacological efforts have been directed at improving memory. At the time of this writing, a handful of drugs known as “Alzheimer’s drugs” or “memory enhancers” have been approved by the U.S. Food and Drug Administration (FDA). In reality, both designations are somewhat misleading. The drugs in question are Read the rest of this entry »

Dr. Andrew Newberg is an Associate Professor in the Department of Radiology and Psychiatry and Adjunct Assistant Professor in the Department of Religious Studies at the University of Pennsylvania. He has published a variety of neuroimaging studies related to aging and dementia. He has also researched the neurophysiological correlates of meditation, prayer, and how brain function is associated with mystical and religious experiences.

Dr. Newberg, thank you for being with us today. Can you please explain the source of your interests at the intersection of brain research and spirituality?

Since I was a kid, I had a keen interest in spiritual practice. I always wondered how spirituality and religion affect us, and over time I came to appreciate how science can help us explore and understand the world around us, including why we humans care about spiritual practices. This, of course, led me to be particularly interested in brain research.

During medical school I was particularly attracted by the problem of consciousness. I was fortunate to meet researcher Dr. Eugene D’Aquili in the early 1990s, who had been doing much research on religious practices effect on brain since the 1970s. Through him I came to see that brain imaging can provide a fascinating window into the brain.

Can we define religion and spirituality -which sound to me as very different brain processes-, and why learning about them may be helpful from a purely secular, scientific point of view?

Good point, definitions matter, since different people may be searching for God in different ways. I view being religious as participating in organized rituals and shared beliefs, such as going to church. Being spiritual, on the other hand, is more of an individual practice, whether we call it meditation, or relaxation, or prayer, aimed at expanding the self, developing a sense of oneness with the universe.

What is happening is that specific practices that have traditionally been associated with religious and spiritual contexts may also be very useful from a mainstream, secular, health point of view, beyond those contexts. Scientists are researching, for example, what Read the rest of this entry »
