The LRRK2 gene is a major contributor to genetic risk for Parkinson’s disease and understanding the biology of the leucine-rich repeat kinase 2 (LRRK2, the protein product of this gene) is an important goal in Parkinson’s research. LRRK2 is a multi-domain, multi-activity enzyme and has been implicated in a wide range of signalling events within the cell. Because of the complexities of the signal transduction pathways in which LRRK2 is involved, it has been challenging to generate a clear idea as to how mutations and disease associated variants in this gene are altered in disease. Understanding the events in which LRRK2 is involved at a systems level is therefore critical to fully understand the biology and pathobiology of this protein and is the subject of this review.
The primary focus of classic cognitive behavioural therapy (CBT) for depression and anxiety is on decreasing symptoms of psychopathology. However, there is increasing recognition that it is also important to enhance wellbeing during therapy. This study investigates the extent to which classic CBT for anxiety and depression leads to symptom relief versus wellbeing enhancement, analysing routine outcomes in patients receiving CBT in high intensity Improving Access to Psychological Therapy (IAPT) Services in the UK. At intake, there were marked symptoms of anxiety and depression (a majority of participants scoring in the severe range) and deficits in wellbeing (a majority of participants classified as languishing, relative to general population normative data). CBT was more effective at reducing symptoms of anxiety and depression than repairing wellbeing. As a result, at the end of treatment, a greater proportion of participants met recovery criteria for anxiety and depression than had moved from languishing into average or flourishing levels of wellbeing. Given the importance of wellbeing to client definitions of recovery, the present results suggest a greater emphasis should be placed on enhancing wellbeing in classic CBT.
Objective
To better characterize differences in interictal sensory experience in adults with migraine and more comprehensively describe the relevance of anxiety to these experiences.
Background
Evidence suggests that sensitivity to sensory input may not be limited to migraine attacks but continues between them. However, there is a need to better understand whether this is the case across senses, and to clearly distinguish sensory experience from measured sensory threshold, which are not straightforwardly related. Previous literature also indicates a co‐occurrence between sensory sensitivity, migraine, and anxiety, but this relationship remains to be fully elucidated.
Methods
The present cross‐sectional study used online questionnaires to investigate how self‐reported sensory experiences relate to migraine in a large community sample including 117 individuals with probable migraine and 827 without. Mediation analyses were also used to determine whether any relationship between migraine and sensory sensitivity was mediated by anxiety.
Results
Significant increases in subjective reports of sensory sensitivity (d = 0.80) and sensory avoidance (d = 0.71) were found in participants with migraine. Anxiety symptoms partially mediated the relationship between subjective sensory sensitivity and migraine. Finally, visual, movement, and auditory subscales were found to provide unique explanatory variance in analyses predicting the incidence of migraine (area under the curve = 0.73, 0.69, 0.62 respectively).
Conclusion
Subjective sensory sensitivities are present between attacks and across senses in individuals with migraine. Anxiety symptoms are relevant to this relationship; however, sensory sensitivities appear to exist independent of this affective influence. The implications of interictal sensitivities for the daily lives of those with migraine should, therefore, be considered in clinical management wherever appropriate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
