Understanding mind and emotion : Longitudinal associations with mental-state talk between young friends

Abstract: Developmental changes in children's understanding of mind and emotion and their mental-state talk in conversations with friends were examined in a longitudinal study of 50 children (M age at each time point = 3 years 11 months, 4 years 6 months, 5 years 0 months). Significant and related improvements over time were found for both theory-of-mind task performance and affective perspective taking. Associated with these cognitive developments were quantitative and qualitative changes in children's references to mental states in their conversations with friends. Individual differences in theory of mind, emotion understanding, and mental-state talk were strikingly stable over the 13-month period. Although there were no gender differences in children's task performances, girls showed more frequent and more developed mental-state talk than boys.

Neuro-otological manifestations of migraine.

Abstract: Vestibulocochlear derangements have been studied in three groups of patients: 200 unselected patients with migraine (Series I), 80 migrainous patients referred because of their symptoms for full neuro-otological examination (Series II), and 116 patients with tension headache who served as controls (Series III). Significant differences were established between tension headache and migraine in respect of incidence and severity of symptoms and their time of onset in relation to the headache. In migraine, vestibulocochlear disturbances can occur as an aura, accompanying the headache or during headache-free periods, the highest incidence occurring during the headache. In Series I, 59 per cent reported vestibular and/or cochlear symptoms and these were of disabling severity in 5 per cent. Significantly, 50 per cent had a history of motion sickness and 81 per cent experienced phonophobia during the headache, the probable mechanism of which is discussed. Persisting vestibulocochlear derangements were found in 77.5 per cent of Series II, largely vestibular and of both central and peripheral origin. Involvement of the vertebrobasilar vascular system appears to be the most likely explanation. Possible links between Meniere's disease, benign paroxysmal vertigo and migraine are discussed.

A double‐blind, placebo‐controlled study to assess the mitochondria‐targeted antioxidant MitoQ as a disease‐modifying therapy in Parkinson's disease

Abstract: Multiple lines of evidence point to mitochondrial oxidative stress as a potential pathogenic cause for Parkinson's disease (PD). MitoQ is a powerful mitochondrial antioxidant. It is absorbed orally and concentrates within mitochondria where it has been shown to protect against oxidative damage. We enrolled 128 newly diagnosed untreated patients with PD in a double-blind study of two doses of MitoQ compared with placebo to explore the hypothesis that, over 12 months, MitoQ would slow the progression of PD as measured by clinical scores, particularly the Unified Parkinson Disease Rating Scale. We showed no difference between MitoQ and placebo on any measure of PD progression. MitoQ does not slow the progression of PD, and this finding should be taken into account when considering the oxidative stress hypothesis for the pathogenesis of PD. © 2010 Movement Disorder Society
