“…Winter seasonal affective disorder is believed to be caused in vulnerable individuals by the shortening of the day, and it responds to light treatment (3,4). In contrast, summer-type seasonal affective disorder consists of recurrent depression in summer and remission of depressive symptoms in fall and winter; it may be caused by exposure to heat and may improve with manipulations of temperature (5,6).…”

“…This may explain the efficacy of modafinil, a narcolepsy medication which increases norepineprine levels, in some SAD patients (54). The light/norepinephrine effect may help offset the vegetative symptoms of SAD and somewhat account for the existence of Reverse SAD, seen in spring and summer months with symptoms of insomnia, anxiety, irritability, decreased appetite, and weight loss (55). Some individuals may be genetically prone to irregularities in the appropriate response to external light signals and/or downstream regulation of serotonin and melatonin.…”

“…41 Higher incidences of SAD are reported in latitudes where there are significant decreases in the hours of daylight in fall/ winter periods. For example, the incidence of SAD in latitudes of [45][46][47][48][49][50] o or higher is over 10% compared to latitudes lower than 30 o , where the prevalence is around 1%. 42 As in atypical depression of those who have SAD, 60% to 90% are women, and it occurs more frequently in younger people, often beginning when the person is at his/her twenties.…”

“…Circadian pacemaker regulates seasonal changes in behavior by transmitting a signal of day duration to the other parts of the organism. [44][45][46] The signal is expressed equally in the period of nocturnal melatonin secretion, which is longer in winter than in summer. The length of nocturnal melatonin secretion is programmed by processes that happen in the cells of the suprachiasmatic nucleus (SCN) of the hypothalamus.…”

Overlap between atypical depression, seasonal affective disorder and chronic fatigue syndrome Superposição entre depressão atípica, doença afetiva sazonal e síndrome da fadiga crônica A b s t r a c t Objective: We reviewed previous studies that have described an association between abnormal functioning of the hypothalamicpituitary-adrenal axis and depression. In addition to melancholic depression, a spectrum of conditions may be associated with increased and prolonged activation of the hypothalamic-pituitary-adrenal axis. In contrast another group of states is characterized by hypoactivation of the stress system, rather than sustained activation, in which chronically reduced secretion of corticotropin releasing factor may result in pathological hypoarousal and an enhanced hypothalamic-pituitary-adrenal negative feedback. Patients with atypical depression, seasonal affective disorder and chronic fatigue syndrome fall in this category. Method: The literature data on the overlap between the key-words were reviewed, summarized and discussed. Results: Many studies suggest that these conditions themselves overlap biologically, showing hypofunction of central corticotropin releasing factor neuronal systems. Conclusions: Therefore, in the real world of clinical practice, patients often present in a grey area between classical idiopathic fatigue and early chronic atypical depression and/or seasonal depression. This underscores the potential common biological links underpinning commom symptom clusters not only between depression (atypical and seasonal) and chronic fatigue syndrome, but also other conditions characterized by in the hypothalamic-pituitary-adrenal axis mainly diminished the corticotropin realising factor activity.Descriptors: Melancholic depression; Seasonal affective disorder; Fatigue syndrome, chronic; Hypothalamus-hypophyseal system; Corticotropin releasing factor Resumo Objetivo: Foram revisados estudos que descrevem que as alterações na função do eixo hipotálamo-pituitária-adrenal e são relacionadas com o estado psicopatológico em depressão. Além da depressão melancólica, uma série de condições podem ser associadas à hiperativação prolongada do eixo hipotálamo-pituitária-adrenal. Um outro grupo de psicopatologias é caracterizado por hipoativação do mesmo eixo com redução crônica na secreção do fator de liberação de corticotrofina. Pacientes com depressão atípica, doença afetiva sazonal e síndrome da fadiga crônica estão inclusos nesta categoria. Método: Foram revisados os dados da literatura que incluem a interseção entre estes descritores, resumidos e discutidos os principais e recentes achados. Resultados: Muitos estudos têm enfatizado que estes quadros se sobrepõem biologicamente, demonstrando hipofunção no sistema relacionado ao fator de liberação de corticotrofina. Conclusões: Na prática clínica, os pacientes frequentemente se apresentam de forma intermediária entre a fadiga e a depressão atípica crônica e/ou a depressão sazonal. Isto enfatiza o potencial biológico comum que fundamenta o grupo de s...
