- Dream recall frequency and content in womenPublication . Pires, Joana; Paiva, Teresa A.S.In several large-scale studies, sex is related to the frequency of dream recall, on average, women tend to recall their dreams more often than men. Studies on EEG analysis and its correlation with dreams in women are scarce. We aimed to evaluate REM dreams ́ recall frequency and content and their emotional characteristics in healthy young women. 20 young women adults’, nonclinical volunteers, without any history pf psychoactive medication and psychiatric disorders performed two consecutive nights of complete Video-Polysomnography recording. REM awakenings dreams were collected, after 10 consecutive minutes of uninterrupted REM. For every dream described, we applied the Hall and Van Castle method of quantitative and systematic dream content analysis and compared to published normative Hall and Van Castle data. The differences of this Portuguese women group and normative USA data obtained in female college students concern mostly dreaming about family, with dead and imaginary characters, while having increased rates of failure and striving. The cultural influences are a possible explanation.
- Dream recall frequency and content in patients with temporal lobe epilepsyPublication . Bentes, Carla; Costa, João; Peralta, Ana Rita; Pires, Joana; Sousa, Paula; Paiva, Teresa A.S.Purpose: To evaluate morning dream recall frequency and content in patients with temporal lobe epilepsy (TLE). Methods: Fifty-two patients with pharmacoresistant TLE submitted to a written dream diary during five consecutive days and continuous video–electroencephalographic (video-EEG) monitoring. A matched control group of 41 healthy subjects completed the same diary at home. The number of recalled dreams (including long dreams) and nonrecalled dream mentation were collected, and the Dream Recall Rate (DRR) was calculated. Hall and Van de Castle dream content analysis was performed. Key Findings: Greater than 70% of patients with TLE (37 of 52) recall their dreams, but DRR rate in these patients is lower than in controls (p £ 0.001). Dream recall does not appear to be influenced by the presence of neuropsychological deficits nor seizure frequency. In dreams descriptions, TLE patients (vs. controls) have a higher percentage of familiarity in settings and fewer dreams with at least one success. Significance: Onirical activity of patients with TLE is different from that of healthy subjects. Our results support the role of mesial and neocortical temporal structures in dream experience. The selective activation of dysfunctional mesial structures may be responsible for some of the observed variability. However, dream content changes can also mirror social and psychological comorbidities of patients with epilepsy.
