Work Summary

Depression is a major health problem that is often chronic or recurrent. Existing treatments have limited effectiveness, and are provided wihtout a clear indication that they will match a particular patient's needs. In this era of precision medicine, we strive to develop neurally-informed treatments for depression and related disorders.

Research Interest

Dr. Allen’s research spans several areas, but the main focus is the etiology and treatment of mood and anxiety disorders. His work focuses on identifying risk factors for depression using electroencephalographic and autonomic psychophysiological measures, especially EEG asymmetry, resting state fMRI connectivity, and cardiac vagal control. Based on these findings, he is developing novel and neurally-informed treatments for mood and anxiety disorders, including Transcranial Ultrasound, EEG biofeedback, and Transcranial Direct Current and Transcranial Alternating Current stimulation. Other work includes understanding how emotion and emotional disorders influence the way we make decisions and monitor our actions. Keywords: Depression, Neuromodulation, EEG, Resting-state fMRI

Abstract:

Background: Premenstrual dysphoric disorder (PMDD) is a chronic condition that significantly affects a woman's well-being on a monthly basis. Although co-occurrence of PMDD and major depressive disorder (MDD) is common, most studies examine whether women with PMDD are at risk for depression and investigations of PMDD in depressed women are scant. Therefore, the present study examined rates of PMDD in young depressed women. Methods: PMDD was assessed using a structured clinical interview (SCID-PMDD) in a sample of 164 young women with (n=85) and without (n = 79) any history of depression. Results: Rates of PMDD were elevated among women with MDD in this sample. This result held true regardless of participants' MDD status (current, lifetime or past history-only symptoms of MDD) and regardless of whether all or most DSM-IV-TR PMDD criteria were met. Limitations: Sample size in the present study was relatively small, and daily diary data were not available to confirm a PMDD diagnosis. Conclusions: The current study highlights the need for clinicians to assess for PMDD in young female patients with major depression. Depressed women experiencing the added physical and psychological burden of PMDD may have a more severe disease course, and future studies will need to identify appropriate treatments for this subset of depressed women. © 2013 Elsevier B.V.

PMID: 18729620;Abstract:

Controversy surrounding dissociative identity disorder (DID) has focused on conflicting findings regarding the validity and nature of interidentity amnesia, illustrating the need for objective methods of examining amnesia that can discriminate between explicit and implicit memory transfer. In the present study, the authors used a cross-modal manipulation designed to mitigate implicit memory effects. Explicit memory transfer between identities was examined in 7 DID participants and 34 matched control participants. After words were presented to one identity auditorily, the authors tested another identity for memory of those words in the visual modality using an exclusion paradigm. Despite self-reported interidentity amnesia, memory for experimental stimuli transferred between identities. DID patients showed no superior ability to compartmentalize information, as would be expected with interidentity amnesia. The cross-modal nature of the test makes it unlikely that memory transfer was implicit. These findings demonstrate that subjective reports of interidentity amnesia are not necessarily corroborated by objective tests of explicit memory transfer. © 2008 American Psychological Association.

PMID: 16316717;PMCID: PMC2835626;Abstract:

Researchers interested in measuring individual differences in affective style via asymmetries in frontal brain activity have depended almost exclusively upon the resting state for EEG recording. This reflects an implicit conceptualization of affective style as a response predisposition that is manifest in frontal EEG asymmetry, with the goal to describe individuals in terms of their general approach or withdrawal tendencies. Alternatively, the response capability conceptualization seeks to identify individual capabilities for approach versus withdrawal responses during emotionally salient events. The capability approach confers a variety of advantages to the study of affective style and personality, and suggests new possibilities for the approach/withdrawal motivational model of frontal EEG asymmetry and emotion. Logical as well as empirical arguments supportive of this conclusion are presented. © 2005 Elsevier B.V. All rights reserved.
