Pollens are a major cause of seasonal allergic diseases. Weather may alter the production of pollens. Increased atmospheric temperatures lead to earlier pollination of many plants and longer duration of pollination, resulting in extended pollen seasons, with early spring or late winter. Longer pollen seasons increase duration of exposure, resulting in more sensitization, and higher pollen concentrations may lead to more severe symptoms. Climate changes in contact to pollens may affect both allergic sensitization and symptom prevalence with severity.

We investigated emotional regulation of autobiographical memories in Alzheimer's disease (AD). AD patients and control participants were asked to retrieve memories in response to “happy” and “sad” cues. Participants were also asked to rate the emotional valence of memories at retrieval as well as at the moment the events were encoded. Results showed that both control participants and AD patients rated memories cued by “happy” as more positive when retrieved than when encoded.
