Ilardi, PhD Date Approved: July 02, 2014 iii Abstract In recent decades, bright light has emerged as a useful tool in numerous clinical and non-clinical applications, with the potential to influence circadian rhythms, sleep, mood, and several other functional domains. However, despite the existence of plausible neurological pathways through which light could also influence social behavior, little is known at this point about the direct effects of bright light exposure on social interaction. Accordingly, the present study – utilizing a sample of young adults endorsing at least mild seasonal fluctuations in clinically relevant domains – examined the acute effects

  • Seasonal Changes in Mood and Behavior Among Diverse
    SEASONAL CHANGES IN MOOD AND BEHAVIOR AMONG CHILDREN AND ADOLESCENTS DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Katharine Davies Smith, M.A. ***** The Ohio State University 2005 Dissertation Committee: Dr. Mary Fristad, Advisor Approved by Dr. Steven Beck ______________________ Dr. Michael Vasey Advisor Dr. Nancy Ryan-Wenger Department of Psychology Copyright by Katharine Davies Smith 2005 ABSTRACT Seasonal mood disorder (SMD) is likely prevalent among children and adolescents; however, there are few empirical investigations of pediatric SMD in the literature. To contribute to the field, the current study investigates the seasonality of mood and behavior among children and adolescents using longitudinal data collected from 1987 to 1998. One hundred eleven youths diagnosed with depression, 369 bereaved youths, 129 community controls, and their parents completed individual assessments at baseline, five, thirteen, and twenty-five months later. Assessment materials include several measures of depressive symptoms and diagnostic instruments. Multilevel analyses were conducted using MlwiN software. According to both parent- and child-report, youths from all three groups earn significantly higher total scores on measures of depression during the winter than the summer. On the other hand, significant seasonal effects do not arise for a measure of overall psychopathology. This implies that seasonality is limited to mood disorders. While this seasonal effect is significant, actual changes of mean scores on measures of depression from the summer to the winter are minimal, suggesting that season may have little affect on the mood and behavior for the majority of participants from each group.

  • Bright Light Therapy for Bipolar Depression
    Bright light therapy for bipolar depression Evidence suggests efficacy as an adjunctive treatment right light therapy (BLT) refers to the use of bright light to treat symptoms of depression. BLT was initially pre- scribed as a treatment for patients with seasonal affec- B 1 tive disorder. It was later found helpful for nonseasonal depression,2 premenstrual dysphoric disorder, postpartum depression, and phase shift circadian disorders, including for patients with dementia whose cognitive function improved after treatment with BLT.3 More recent studies suggest year- round benefit for nonseasonal depression.2 The American Psychiatric Association practice guidelines for the treatment of depression list BLT as an alternative and/or addition to pharmacologic and psychological treatment.4 BLT also may be beneficial for patients who are in the depressive phase of bipolar illness.

Photobiomodulation and the brain: a new paradigm Madison Hennessy1 and Michael R Hamblin2,3,4 1Briarcliff High School, Briarcliff Manor, NY, USA 2Wellman Center for Photomedicine, Massachusetts General Hospital, Boston, MA, USA 3Department of Dermatology, Harvard Medical School, Boston, MA, USA 4Harvard-MIT Division of Health Sciences and Technology, Cambridge, MA, USA Abstract Transcranial photobiomodulation (PBM) also known as low level laser therapy (tLLLT) relies on the use of red/NIR light to stimulate, preserve and regenerate cells and tissues. The mechanism of action involves photon absorption in the mitochondria (cytochrome c oxidase), and ion channels in cells leading to activation of signaling pathways, up-regulation of transcription factors, and increased expression of protective genes. We have studied PBM for treating traumatic brain injury (TBI) in mice using a NIR laser spot delivered to the head. Mice had improved memory and learning, increased neuroprogenitor cells in the dentate gyrus and subventricular zone, increased BDNF and more synaptogenesis in the cortex. These highly beneficial effects on the brain suggest that the applications of tLLLT are much broader than at first conceived. Other groups have studied stroke (animal models and clinical trials), Alzheimer’s disease, Parkinson’s disease, depression, and cognitive enhancement in healthy subjects. Keywords Transcranial photobiomodulation; low level laser therapy; brain disorders; traumatic brain injury; stroke; Alzheimer’s disease; psychiatric diseases 1 Introduction Light in the visible and near-infrared spectrum makes up the major part of solar radiation and is also provided by artificial light sources.

  • The Use of Bright Light in the Treatment of Insomnia
    Chapter e39 The Use of Bright Light in the Treatment of Insomnia Leon Lack and Helen Wright Department of Psychology, Flinders University, Adelaide, South Australia PROTOCOL NAME The use of bright light in the treatment of insomnia. GROSS INDICATION Certain types of insomnia that are associated with abnormal timing of circa- dian rhythms may be treated with bright light therapy. SPECIFIC INDICATION Some individuals with sleep onset insomnia experience difficulty falling asleep at a “normal time” but no difficulty maintaining sleep once it is initi- ated. Individuals with this type of insomnia may have a delayed or later timed circadian rhythm. Bright light therapy timed in the morning after arising can advance or time circadian rhythms earlier and thus would be indicated for sleep onset or initial insomnia. Morning bright light therapy is also indicated for the related problem of delayed sleep phase disorder. Individuals experiencing early morning awakening insomnia have no diffi- culty initiating sleep but their predominant difficulty is waking before intended and not being able to resume sleep. These individuals may have an advanced or early timed circadian rhythm. Bright light therapy in the evening before sleep would be indicated for this type of insomnia as well as for the more extreme version, advanced sleep phase disorder. CONTRAINDICATIONS Bright light therapy would not be recommended in the following cases: ● Insomnia in which there is no indication of abnormal timing of circadian rhythms (e.g. combined problem initiating and maintaining sleep, having no strong morning or evening activity preferences) Behavioral Treatments for Sleep Disorders.

  • Light Therapy and the Management of Winter Depression John M
    Advances in PsychiatricLight therapy Treatment in seasonal (2004), affective vol. 10, disorder233–240 Light therapy and the management of winter depression John M. Eagles Abstract Much the most common type of seasonal affective disorder at temperate latitudes is recurrent winter depression, which probably affects around 3% of adults in the UK to a clinically significant degree. In this article, diagnosis and presentation are discussed and symptoms are contrasted with those of non- seasonal depression. Aetiology and epidemiology, with regard to age, gender and latitude of residence, are described. Sufferers are often treated with light therapy, and this is described in some detail, with mention of effectiveness, prediction of outcome, timescales of response, side-effects, use of lightboxes and alternatives to lightboxes. Other general aspects of the management of seasonal affective disorder, including the use of antidepressant medication, are also outlined. The main purpose of this article is to discuss the profound melancholia has supervened, which in use of light therapy in seasonal affective disorder. spring passes into mania, which again in autumn There are two recognised forms of this disorder. gradually gives way to melancholia’.

  • LIGHT THERAPY for MAJOR DEPRESSION a Game Changer for Physicians
    34 North Seventh Street Center for Suite NPH2-E Environmental Brooklyn, NY 11249-3793 Therapeutics www.cet.org a 501(c)(3) nonprofit foundation 646-837-7337 LIGHT THERAPY FOR MAJOR DEPRESSION A Game Changer for Physicians An ambitious 2016 study in JAMA Psychiatry has compared SSRI and light treatment for Major Depressive Disorder (MDD). This brochure shows how you can use that research to enhance your treatment of MDD with three essential tips and a set of online resources for clinicians. While light therapy for seasonal affective disorder has taken its place in clinical practice with endorsement by an American Psychiatric Association task force, only a few exploratory studies supported its efficacy for nonseasonal depression ― until now. The verdict came with the new eight-week, randomized, placebo- controlled multicenter study of 122 outpatients. Raymond W. Lam, MD, of the University of British Columbia, directed the trial in association with Toronto colleagues Anthony J. Levitt, MD, and Robert D. Levitan, MD. The Ray Lam investigators compared two treatments for MDD, tested against two placebos. The results were clear: Light therapy and the combination of light therapy with an antidepressant were superior to the antidepressant alone by a large margin. The patients were randomly assigned to one of four groups: Light and antidepressant combination treatment: light therapy (10,000 lux fluorescent white light early in the morning for 30 minutes), plus fluoxetine 20 mg Light only: light therapy plus “dummy” pills Antidepressant only: fluoxetine 20 mg, plus an inactivated negative ion generator that hummed as if it were working Placebos: dummy pills and the inactivated ion generator Copyright © 2016, Center for Environmental Therapeutics.

University of Oviedo Centro de Investigación Biomédica en Red de Salud Mental (CIBERSAM), Ministry of Science and Innovation SPAIN ABSTRACT – Background and Objectives: Recent decades have seen significant ad- vances in the knowledge of pathogenesis of mood disorders, as well as of other conditions directly or indirectly related to such diseases. Such progress has led to the emergence of new treatments, such as bright light therapy, based on the discovery of the therapeutic ef- fects of exposure to bright light with the so-called seasonal affective disorder (SAD), a DSM seasonal pattern specifier linked to major depression and bipolar disorder recurrent describing the course of illness during seasons. The goal of the present work is to review the potential clinical applications of phototherapy, including SAD, obsessive-compulsive disorder, bulimia, premenstrual syndrome, non seasonal major depression, sleep disor- ders, jet-lag, dementia, normal populations and in primary care. Methods: A systematic review of the literature about this matter since the early Rosen- thal’s group observations has been carried out. Results: A considerable number of studies has been published about this therapeutic approach, pointing that not only depression but also other pathologies that may follow a seasonal pattern could benefit from phototherapy integrated with more standard treat- ments, as well as other disorders directly or indirectly related to mood, and even another conditions without a seasonal pattern.
