A gentleman from Utah has a condition which is baffling brain scientists. The left side of his brain is shrinking, although the right-hand side seems fine.
He is currently being investigated by neurologists at the University of Utah, Brain Institute.
His brain scan is shown in the picture on the left.
NB: brain scans done by radiologists have left and right reversed, as they label their scans as if they were looking at the patient as they lie on their backs in the scanner, so the patient’s left is on the viewer’s right.
