Missouri Appellate Court Affirms $800K Judgment Against Psychiatrist for Vyvanse-Induced Stroke

“All of that said, even if F.D.’s differential diagnosis was thus unreliable and should not have been admitted, other substantial evidence at trial tended to prove that K.P.’s death was caused by Vyvanse use. This Court will not reverse a judgment unless the circuit court’s error in admitting expert testimony ‘materially affected the merits of the action,'” Missouri Court of Appeals Judge Cristian M. Stevens.
