Peter V. Rabins, M.D., M.P.H.
Barry W. Rovner, M.D.
Teresa Rummans, M.D.
Lon S. Schneider, M.D.
Pierre N. Tariot, M.D.
During development and approval of this guideline watch, from July 2012 to September 2014, Dr. Rabins reports providing legaltestimony for Janssen Pharmaceutica, Dr. Rovner reports serving as a consultant to GE Healthcare, and Dr. Rummans reports thatshe has nothing to disclose. From 3 years before development was initiated in July 2012 through September 2014, Dr. Schneider andthe University of Southern California received research or other grants from Abbott Laboratories, AstraZeneca, Baxter, Forest Phar-maceuticals, Inc., Forum, Genentech, Johnson & Johnson, Eli Lilly and Company, Lundbeck, Merck, Myriad, Novartis, Pfizer,Roche, and TauRx, Ltd. and from NIH (USC ADRC, ADCS, ADNI, Banner Alzheimer's Initiative, CitAD, phytoSERMs, Alzheim-er's disease trial simulations, allopregnanolone, P50 AG05142, R01 AG033288, R01 AG037561, UF1 AG046148), and the state ofCalifornia (California Alzheimer's Disease Program, California Institute for Regenerative Medicine). During that same time period,Dr. Schneider served as a consultant or on advisory panels for Abbott Laboratories, Abbvie, AC Immune, Accera, Allon, AstraZeneca,Avraham Pharmaceuticals, Ltd., Biogen Idec, Cerespir, Forest Pharmaceuticals, Inc., Forum, GSK, Johnson & Johnson, Eli Lilly andCompany, Lundbeck, Merck, Novartis, Orion, Roche, Servier, Stemedica, Ltd., Takeda, Targacept, TauRx, Toyama/FujiFilm, andZinfandel. In addition, Dr. Schneider serves on the editorial boards of
Alzheimer's and Dementia: Translational Research and ClinicalIntervention (editor-in-chief),
The Lancet Neurology (editorial board),
Cochrane Collaboration (editor base),
BMC Psychiatry (section ed-itor),
Alzheimer's & Dementia (senior associate editor),
Current Alzheimer Research (associate editor),
Clinical Neuropharmacology (edi-torial board) and on the guidelines committee for the World Federation of Societies of Biological Psychiatry; served as an expert wit-ness or consultant on federal and state cases for plaintiffs against Lilly, Johnson & Johnson, and Pfizer and for defendants AstraZenecaand Pfizer; and has consulted with the state of California Department of Justice. During development and approval of this guidelinewatch, Dr. Tariot reports receiving consulting fees from Abbott Laboratories, AbbVie, AC Immune, Adamas, Avanir, Avid, Boehringer-Ingelheim, Bristol Myers Squibb, California Pacific Medical Center, Chase Pharmaceuticals, Chiesi, CME, Inc., Cognoptix, Elan,Eli Lilly, GlaxoSmithKline, Janssen, Medavante, Medivation, Merck and Company, Merz, Otsuka, Roche, and Sanofi-Aventis. Dr.
Tariot reports receiving research support from AstraZeneca, Avanir, Avid, Baxter Healthcare Corp., Bristol Myers Squibb, Cognop-tix, Eli Lilly, Functional Neuromodulation (f(nm)), GE, Genentech, GlaxoSmithKline, Janssen, Medivation, Merck and Company,Pfizer, Roche, Targacept, and Toyama as well as the National Institute on Aging and the Arizona Department of Health Services. Dr.
Tariot also reports stock options in Adamas and that he is listed as a contributor to a patent owned by the University of Rochester,"Biomarkers of Alzheimer's Disease."
The American Psychiatric Association's (APA's) practice guidelines are developed by expert work groups using an explicit method-
ology that includes rigorous review of available evidence, broad peer review of iterative drafts, and formal approval by the APA As-sembly and Board of Trustees. APA practice guidelines are intended to assist psychiatrists in clinical decision making. They are notintended to be a standard of care. The ultimate judgment regarding a particular clinical procedure or treatment plan must be madeby the psychiatrist in light of the clinical data presented by the patient and the diagnostic and treatment options available.
Guideline watches summarize significant developments in practice that have occurred since publication of an APA practice guide-
line. Watches may be authored and reviewed by experts associated with the original guideline development effort and are approvedfor publication by APA's Executive Committee on Practice Guidelines. Thus, watches represent the opinion of the authors and ap-proval of the Executive Committee but not APA policy.

Translating cell biology intotherapeutic advancesin Alzheimer's diseaseDennis J. Selkoe Studies of the molecular basis of Alzheimer's disease exemplify the increasingly blurred distinction between basic andapplied biomedical research. The four genes so far implicated in familial Alzheimer's disease have each been shown toelevate brain levels of the self-aggregating amyloid-b protein, leading gradually to profound neuronal and glialalteration, synaptic loss and dementia. Progress in understanding this cascade has helped to identify specifictherapeutic targets and provides a model for elucidating other neurodegenerative disorders.
