often asked what are recommended or must read papers in psychiatry that are clinically relevant. here is my list of recommended papers to work one's way through during the first two years of residency.
Psychosis
Agid O, Kapur S, Arenovich T, Zipursky RB. Delayed-onset hypothesis of antipsychotic action: a hypothesis tested and rejected. Arch Gen Psychiatry 2003; 60:1228-1235
This study shows that if antipsychotics don’t have an effect in the first week, they probably never will, and the most pronounced effects are in the first two weeks of treatment.
Andreasen NC, Liu D, Ziebell S, Vora A, Ho BC. Relapse duration, treatment intensity, and brain tissue loss in schizophrenia: a progressive longitudinal MRI study. Am J Psychiatry 2013; 170:609-615
Important study finding antipsychotics cause brain shrinkage rather than relapses, and suggest using the lowest doses possible
Chouinard G, Jones BD. Neuroleptic-induced supersensitivity psychosis: clinical and pharmacologic characteristics. Am J Psychiatry 1980; 137:16-21
One of the first papers to introduce the possibility of a neuroleptic-induced supersensitivity psychosis
Demjaha A, Murray RM, McGuire PK, Kapur S, Howes OD. Dopamine synthesis capacity in patients with treatment-resistant schizophrenia. Am J Psychiatry 2012; 169:1203-1210
This paper shows that dopamine dysregulation is not found in those with treatment resistant schizophrenia and thus dopamine antagonists are worthless in these patients
Fletcher PC, Frith CD. Perceiving is believing: a Bayesian approach to explaining the positive symptoms of schizophrenia. Nat Rev Neurosci 2009; 10:48-58
An extremely clever model uniting Schneider’s first rank symptoms as theory of mind deficits in context of other biological and neuropsychological findings in schizophrenia
Fusar-Poli P, Borgwardt S, Bechdolf A et al. The psychosis high-risk state: a comprehensive state-of-the-art review. JAMA Psychiatry 2013; 70:107-120
Extremely useful review of the field of prodromal or at-risk mental state
Honer WG, Thornton AE, Chen EYH et al. Clozapine alone versus clozapine and risperidone with refractory schizophrenia. N Engl J Med 2006; 354: 472-482
CARE study showed adding risperidone to clozapine no more effective than clozapine alone
Jones PB, Barnes TR, Davies L et al. Randomized controlled trial of the effect on quality of life of second- vs first-generation antipsychotic drugs in schizophrenia: cost utility of the latest antipsychotic drugs in schizophrenia study (CUtLASS 1) Arch Gen Psychiatry 2006; 63:1079-87
CUtLASS study was British equivalent of the CATIE using more of the typical antipsychotics and confirming the new drugs cost more and have no additional benefit on quality of life
Kahn RS, Fleischhacker WW, Boter H et al. Effectiveness of antipsychotic drugs in first-episode schizophrenia and schizophreniform disorder: an open randomised clinical trial. Lancet 2008; 371:1085-97
EUFEST study found that first-episode psychosis like chronic schizophrenia responds just as well to the older drugs as the newer drugs
Kane J, Hongfeld G, Singer J, Meltzer H and the Clozaril Collaborative Study Group. Clozapine for the treatment resistant schizophrenic: a double-blind comparison with chlorpromazine. Arch Gen Psychiatry 1988; 45:789-796
Classic study demonstrating clozapine’s superiority to chlorpromazine in treatment-resistant schizophrenia that led to re-discovery of clozapine in clinical practice
Kapur S. Psychosis as a state of aberrant salience: a framework linking biology, phenomenology, and pharmacology in schizophrenia. Am J Psychiatry 2003; 160:13-23
A modern classic, this paper describes how the dopamine hypothesis can explain the positive symptoms of schizophrenia
Leff J, Sartorium N, Jablensky A, Korten A, Ernberg G. The International Pilot Study of Schizophrenia: five-year follow-up findings. Psychol Med 1992; 22:131-145
Five-year follow up of the IPSS which found prognosis of schizophrenia was better in developing countries than in the developed world
Leucht S, Cipriani A, Spineli L et al. Comparative efficacy and tolerability of 15 antipsychotic drugs in schizophrenia: a multiple treatments meta-analysis. Lancet 2013; 382:951-962
This meta-analysis shows substantial differences in efficacy and side-effect profiles of different antipsychotic agents with clozapine, amisulpride and olanzapine coming out as most effective, and asenapine, lurasidone, and iloperidone coming out as least effective
Lieberman JA, Stroup TS, McEvoy JP et al. Effectiveness of Antipsychotic Drugs in Patients with Chronic Schizophrenia. N Engl J Med 2005; 353:1209-1223
CATIE study showed olanzapine was more effective than other atypical antipsychotics and ziprasidone less effective, with no difference between typical and atypical antipsychotics
Tiihonen J, Lonngvist J, Wahlbeck K et al. 11-year follow-up of mortality in patients with schizophrenia: a population based cohort study (FIN11 study). Lancet 2009; 374:620-627
This study found clozapine was associated with reduced morality in comparison to other antipsychotics or no treatment in schizophrenia
Wunderink L, Nieboer RM, Wiersma D, Sytema S, Nienhuis FJ. Recovery in remitted first-episode psychosis at 7 years of follow-up of an early dose reduction/discontinuation or maintenance treatment strategy: long-term follow-up of a 2-year randomized clinical trial. JAMA Psychiatry 2013; 70:913-920
Controversial study that confirms older data that continued antipsychotic use leads to poorer functional outcomes with better symptom control than discontinuation/early dose reduction
