Alexithymia and its impact on quality of life in a group of Brazilian women with migraine without aura.

BACKGROUND: Migraine is a type of primary headache widely known for its impact on quality of life of patients. Although the psychological aspects of the disease are receiving increasing attention in current research, some of them, as alexithymia, are still seldom explored. This study aimed to provide evidence on the relationships between markers of depression, anxiety, alexithymia, self-reflection, insight and quality of life in migraine. METHODS: Forty female outpatients from a Brazilian specialized headache hospital service and a paired control group were compared. RESULTS: The results revealed that women with migraine had higher levels of depression, anxiety and alexithymia, and lower levels of quality of life, self-reflection and insight, compared to controls. Quality of life in women with migraine was predicted by levels of depression and one alexithymia factor (ability to express emotions and fantasies). A binary regression analysis between clinical and control groups revealed the migraine group to comprise individuals with high anxiety, low quality of life in the physical domain and the presence of a concrete thinking style. CONCLUSIONS: The results highlight the relevance of considering psychological variables in the routine healthcare practices for migraine patients in general, while keeping steady attention to individual case features.

Childhood trauma, impulsivity, and executive functioning in crack cocaine users.

BACKGROUND: The use of crack cocaine is a major public health concern in Brazil and internationally. Recent data suggest that childhood trauma is associated with worse outcomes among cocaine users. This study had the objective of evaluating the relationship of childhood trauma with executive functioning and impulsivity in outpatients with crack cocaine use disorders. METHODS: This is a cross-sectional study of 84 consecutive outpatients with a primary crack cocaine use disorder who sought treatment in Porto Alegre, Brazil. Childhood trauma was evaluated with the Childhood Trauma Questionnaire; executive functioning, with the Wisconsin Card Sorting Test; and impulsivity, with the Barratt Impulsivity Scale. RESULTS: Childhood trauma was strongly associated with executive dysfunction and impulsivity, even when controlled for possible confounders. CONCLUSIONS: Childhood trauma may be associated with executive dysfunction and impulsivity in crack cocaine users. The full impact of trauma needs to be further investigated in longitudinal studies.
