Paul Thompson directs the ENIGMA Consortium, a global alliance of 307 scientists in 33 countries who conduct the largest studies of 10 major brain diseases – ranging from schizophrenia, depression, ADHD, bipolar illness and OCD, to HIV and addictions on the brain. ENIGMA’s genomic screens of over 31,000 people’s brain scans and genome-wide data (published in Nature Genetics, 2012; Nature, 2015) have brought together experts from 185 institutions to unearth genetic variants that affect brain structure, disease risk, and brain connectivity.
