There is a paucity of long-term prospective disaster studies of the psychological sequelae among survivors.

At 1½ and 25 years after the Spitak earthquake, 142 early adolescents from two cities were assessed: Gumri (moderate–severe exposure) and Spitak (very severe exposure). The Gumri group included treated and not-treated subjects, while the Spitak group included not-treated subjects. Instruments included: DSM-III-R PTSD-Reaction Index (PTSD-RI); DSM-5 PTSD-Checklist (PCL); Depression Self-Rating Scale (DSRS); and Center for Epidemiological Studies-Depression Scale (CES-D).

(1) Between 1½ and 25 years, PTSD rates and mean scores decreased significantly in the three groups (over 50%). However, at 25 years 9.1–22.4% met DSM-5 PTSD criteria. (2) At 1½ years, the Spitak group had higher PTSD-RI (p < 0.001) and DSRS scores (p < 0.001) compared to the Gumri-not-treated group. At 25 years, the Spitak group that had experienced fewer post-earthquake adversities (p < 0.03), had a greater decrease in PTSD-RI scores (p < 0.02), and lower CES-D scores (p < 0.01). (3) Before treatment, PTSD-RI and DSRS scores did not differ between the Gumri-treated and not-treated groups. At 25-years, the Gumri-treated group showed a greater decrease in PTSD-RI scores (p < 0.03), and lower mean PTSD-RI (p < 0.02), PCL (p < 0.02), and CES-D (p < 0.01) scores. (4) Predictors of PTSD symptom severity at 25-years included: home destruction, treatment, social support, post-earthquake adversities, and chronic medical illnesses.

Post-disaster PTSD and depressive symptoms can persist for decades. Trauma-focused treatment, alleviation of post-disaster adversities, improving the social ecology, and monitoring for chronic medical illnesses are essential components of recovery programs.

This study proposed to test the postulate that the anxiety and insomnia symptom cluster (A/I) is a predictor of dementia.

A retrospective data analysis was conducted on the Aging, Demographics, and Memory Study (ADAMS) dataset in order to determine whether A/I symptoms or treatment were associated with subsequent dementia or cognitive impairment (DOCI). The study used logistic regression analysis and comparison of incidence rates on a sample of 249 participants.

There was a significant relationship between A/I symptoms and subsequent DOCI in the male gender that was not found in the total sample or in females. No association with subsequent DOCI was found for benzodiazepine usage or non-benzodiazepine A/I medication usage.

The gender differences identified suggest prodromal dementia phenotypes that are differentially expressed in males and females. By triangulating the approaches from multiple disciplines—such as neuroimaging and genetics—with prodromalsymptoms, it is possible that reliable early prediction may be accomplished.
