Article
UCL The recently recognised association between hearing impairment and dementia has important clinical and public health implications but remains poorly understood. In daily life, the most important sound we hear is speech: making sense of spoken messages that are ‘degraded’ by noise is fundamental to suc- cessful communication and depends on neura...
Article
Background Whilst current diagnostic criteria for primary progressive aphasia syndromes (PPA) emphasise impaired language output and linguistic processing, deficits of auditory analysis are increasingly rec- ognised in PPA syndromes. We assessed phonemic discrimination and its neuroanatomical correlates in patients representing all major PPA varian...

Phonemic restoration – perceiving speech sounds that are actually missing – is a fundamental perceptual process that ‘repairs’ interrupted spoken messages during noisy everyday listening. As a dynamic, integrative process, phonemic restoration is potentially affected by neurodegenerative pathologies but this has not been clarified. Here we studied...

Objectives We explored whether adapting traditional neuropsychological tests for online administration against the backdrop of COVID-19 was feasible for people with diverse forms of dementia and healthy older controls. We compared face-to-face and remote settings to ascertain whether remote administration affected performance. Design We used a lon...
Article
Background: The use of videoconferencing technology has increased as an alternative communication method for people to retain social and clinical contact during Covid-19 restrictions. This study investigated the uptake, limitations and benefits of videoconferencing for people living with dementia (PLWD). Method: Twenty-three PLWD, 87 caregivers...
Article
Background: The compulsory introduction of wearing face coverings and social distancing to curb the spread of Covid-19 in the United Kingdom has reduced both the quality of auditory information and availability of visual and non-verbal cues during conversations with others. This is likely to have a greater impact on efficiency and effectiveness of...

The speech we hear every day is typically “degraded” by competing sounds and the idiosyncratic vocal characteristics of individual speakers. While the comprehension of “degraded” speech is normally automatic, it depends on dynamic and adaptive processing across distributed neural networks. This presents the brain with an immense computational chall...

Purpose of Review The term primary progressive aphasia (PPA) refers to a diverse group of dementias that present with prominent and early problems with speech and language. They present considerable challenges to clinicians and researchers. Recent Findings Here, we review critical issues around diagnosis of the three major PPA variants (semantic v...

Logopenic variant primary progressive aphasia (lvPPA) is the least well defined of the major primary progressive aphasia (PPA) syndromes. We assessed phoneme discrimination in patients with PPA (semantic, nonfluent/agrammatic, and logopenic variants) and typical Alzheimer’s disease, relative to healthy age‐matched participants. The lvPPA group perf...
