The presence and degree of specialization between the anterior temporal lobes (ATLs) is a key issue in debates about the neural architecture of semantic memory. Here, we comprehensively assessed multiple aspects of semantic cognition in a large group of postsurgical temporal lobe epilepsy (TLE) patients with left versus right anterior temporal lobectomy (n = 40). Both subgroups showed deficits in expressive and receptive verbal semantic tasks, word and object recognition, naming and recognition of famous faces and perception of faces and emotions. Graded differences in performance between the left and right groups were secondary to the overall mild semantic impairment; primarily, left resected TLE patients showed weaker performance on tasks that required naming or accessing semantic information from a written word. Right resected TLE patients were relatively more impaired at recognizing famous faces as familiar, although this effect was observed less consistently. These findings unify previous partial, inconsistent results and also align directly with fMRI and transcranial magnetic stimulation results in neurologically intact participants. Taken together, these data support a model in which the 2 ATLs act as a coupled bilateral system for the representation of semantic knowledge, and in which graded hemispheric specializations emerge as a consequence of differential connectivity to lateralized speech production and face perception regions.
Despite changes to public perceptions and legislative protection over the last 20 years, high rates of MS patients still leave the workforce prematurely, reduce working hours or change employment roles. These data have significant implications when considering social and economic impacts of MS, support the value of employment metrics as long-term outcome measures, and demonstrate the need to improve employment requirements and flexibility of working practices in individuals with MS.
Results suggest NMO is a difficult condition to live with due to the unpredictability of relapses and accrued disability of visual or spinal symptoms occurring with each relapse. Poor vision, reduced mobility, bladder dysfunction and pain affected participants' independence and experience of living with NMO. Participants reported that during relapse and recovery they would "put their life on hold". They identified the importance of periods of stability to enable them to adjust to their condition and therefore aim for "normality" of life that they believed was comparable to their peers. Implications for Rehabilitation Disability due to NMO has a major impact on an individual's life, abilities and identity. Timely treatment of relapse is essential to reduce or prevent disability. Health care professionals need to coordinate care locally and nationally. Multi-disciplinary work is vital to promote adjustment, coping strategies and support for people living with NMO.
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.
