Lifelong impact of extreme stress on the human brain: Holocaust survivors study

Alterations in corpus callosum subregions morphology and functional connectivity in patients with adult-onset hypothyroidism

BACKGROUND

Magnetic resonance imaging (MRI) brain abnormalities have been reported in the corpus callosum (CC) of patients with adult-onset hypothyroidism. However, no study has directly compared CC-specific morphological or functional alterations among subclinical hypothyroidism (SCH), overt hypothyroidism (OH), and healthy controls (HC). Moreover, the association of CC alterations with cognition and emotion is not well understood.

METHODS

Demographic data, clinical variables, neuropsychological scores, and MRI data of 152 participants (60 SCH, 37 OH, and 55 HC) were collected. This study investigated the clinical performance, morphological and functional changes of CC subregions across three groups. Moreover, a correlation analysis was performed to explore potential relationships between these factors.

RESULTS

Compared to HC, SCH and OH groups exhibited lower cognitive scores and higher depressive/anxious scores. Notably, rostrum and rostral body volume of CC was larger in the SCH group. Functional connectivity between rostral body, anterior midbody and the right precentral and dorsolateral superior frontal gyrus were increased in the SCH group. In contrast, the SCH and OH groups exhibited a decline in functional connectivity between splenium and the right angular gyrus. Within the SCH group, rostrum volume demonstrated a negative correlation with Montreal Cognitive Assessment and visuospatial/executive scores, while displaying a positive correlation with 24-item Hamilton Depression Rating Scale scores. In the OH group, rostral body volume exhibited a negative correlation with serum thyroid stimulating hormone levels, while a positive correlation with serum total thyroxine and free thyroxine levels.

CONCLUSIONS

This study suggests that patients with different stages of adult-onset hypothyroidism may exhibit different patterns of CC abnormalities. These findings offer new insights into the neuropathophysiological mechanisms in hypothyroidism.

Holocaust survivors: Health and longevity 70 years later

BACKGROUND

Holocaust survivors (HS) alive today form a unique and disappearing population, whose exposure to systematic genocide occurred over 70 years ago. Negative health outcomes were widely documented prior to age 70. We examine the hypothesis that the experience of remote trauma continues to negatively affect health, functional status, and survival between the ages of 85-95.

METHODS

The Jerusalem Longitudinal Study (1990-2022) followed a representative sample of Jerusalem residents born 1920-1921, at ages 85, 90 and 95. Home assessment included medical, social, functional, and cognitive status, and mortality data. Subjects were classified: (1) HS-Camp (HS-C): survived slave-labor, concentration, or death camps; (2) HS-Exposed (HS-E): survived Nazi occupation of Europe; (3) Controls: European descent, outside Europe during WWII. We determined Hazards Ratios (HR), adjusting for gender, loneliness, financial difficulty, physical activity, ADL dependence, chronic ischemic heart disease, cancer, cognitive deficits, chronic joint pain, self-rated health.

RESULTS

At ages 85 (n = 496), 90 (n = 524), and 95 (n = 383) the frequency of HS-C versus HS-E versus Controls was 28%/22%/50%, 19%/19%/62%, and 20%/22%/58%, respectively. No consistent significant morbidity differences were observed. Mortality between ages 85-90 and 90-95 years was 34.9% versus 38% versus 32.0%, and 43.4% versus 47.3% versus 43.7%, respectively, with no significant differences in survival rates (log rank p = 0.63, p = 0.81). Five-year mortality adjusted HRs were insignificant for HS-C and HS-E between ages 85-90 (HR 0.87, 95% CI 0.54-1.39; HR 1.14, 95% CI 0.73-1.78) and ages 90-95 (HR 0.72, 95% CI 0.39-1.32; HR 1.38, 95% CI 0.85-2.23).

CONCLUSIONS

Seventy years following their trauma and suffering during the Holocaust, the significant impairments of health, function, morbidity, and mortality which have accompanied survivors throughout their entire adult life, were no longer observed. Indeed, it is likely that survivors living >85 years old represent a uniquely resilient population of people, whose adaptation to adversity has accompanied them throughout their lives.

Lifelong effects of prenatal and early postnatal stress on the hippocampus, amygdala, and psychological states of Holocaust survivors

This study focuses on hippocampal and amygdala volume, seed-based connectivity, and psychological traits of Holocaust survivors who experienced stress during prenatal and early postnatal development. We investigated people who lived in Central Europe during the Holocaust and who, as Jews, were in imminent danger. The group who experienced stress during their prenatal development and early postnatal (PreP) period (n = 11) were compared with a group who experienced Holocaust-related stress later in their lives: in late childhood, adolescence, and early adulthood (ChA) (n = 21). The results of volumetry analysis showed significantly lower volumes of both hippocampi and the right amygdala in the PreP group. Seed-based connectivity analysis revealed increased connectivity from the seed in the right amygdala to the middle and posterior cingulate cortex, caudate, and inferior left frontal operculum in the PreP group. Psychological testing found higher levels of traumatic stress symptoms (TCS-40) and lower levels of well-being (SOS-10) in the PreP group than in the ChA group. The results of our study demonstrate that extreme stress experienced during prenatal and early postnatal life has a profound lifelong impact on the hippocampus and amygdala and on several psychological characteristics.

Life and mental health in limbo of the Ukraine war: How can helpers assist civilians, asylum seekers and refugees affected by the war?

The terror spread by the war disrupts lives and severs families, leaving individuals and communities devastated. People are left to fend for themselves on multiple levels, especially psychologically. It is well documented that war adversely affects non-combatant civilians, both physically and psychologically. However, how the war puts civilians' lives in a limbo is an under-researched area. This paper focuses on three aspects: (1) how the mental health and well-being of Ukrainian civilians, asylum seekers, and refugees are affected by the war caused limbo; (2) what factors affect this process of being stuck in the limbo of war; and (3) how psychologists and helpers in the war-ridden and host countries can provide meaningful support. Based on the authors' own practical work with Ukrainian civilians, refugees, and professional helpers during the war, this paper provides an overview of multi-level factors that impact human psyches in a war, and possible ways to help those who are living in the war limbo. In this research and experiential learning-based review, we offer some helpful strategies, action plans, and resources for the helpers including psychologists, counselors, volunteers, and relief workers. We emphasize that the effects of war are neither linear nor equal for all civilians and refugees. Some will recover and return to a routine life while others will experience panic attacks, trauma, depression, and even PTSD, which can also surface much later and can prolong over the years. Hence, we provide experience-based ways of dealing with short-term and prolonged trauma of living with war and post-traumatic stress disorder (PTSD). Mental health professionals and other helpers in Ukraine and in host countries can use these helping strategies and resources to provide effective support for Ukrainians and for war refugees in general.

The U.S. Needs a National Human Health Observing System

The COVID-19 pandemic and increasing frequency and severity of environmental disasters reveal an urgent need for a robust health observing/surveillance system. With the possible exception of Brazil, we know of no such comprehensive health observing capacity. The US should create a national system of linked regionally-based health monitoring systems similar to those for weather, ocean conditions, and climate. Like those for weather, the health observing system should operate continuously, collecting mental, physical, and community health data before, during, and after events. The system should include existing cross-sectional health data surveys, along with significant new investment in regional longitudinal cohort studies. The recently described framework for a Gulf of Mexico Community Health Observing System is suggested as a potential model for development of a nation-wide system.
