A steady stream of nicotine normalises genetically-induced impairments in brain activity associated with schizophrenia, according to a new study that could lead to new non-addictive, nicotine-based treatments for the 51 million people worldwide who suffer from the disease.
The finding sheds light on what causes the disease and why those who have it tend to smoke heavily. It could also potentially have applications for treating addiction, Attention Deficit Hyperactivity Disorder, Bipolar disorder and other psychiatric conditions.
