TLDR
Using a semi-structured caregiver questionnaire and MRI voxel-based morphometry in patients with frontotemporal degeneration or Alzheimer’s disease, Fletcher et al. show that symptoms are underpinned by atrophy in a distributed thalamo-temporo-insular network implicated in somatosensory processing.Abstract:
Symptoms suggesting altered processing of pain and temperature have been described in dementia diseases and may contribute importantly to clinical phenotypes, particularly in the frontotemporal lobar degeneration spectrum, but the basis for these symptoms has not been characterized in detail. Here we analysed pain and temperature symptoms using a semi-structured caregiver questionnaire recording altered behavioural responsiveness to pain or temperature for a cohort of patients with frontotemporal lobar degeneration (n = 58, 25 female, aged 52-84 years, representing the major clinical syndromes and representative pathogenic mutations in the C9orf72 and MAPT genes) and a comparison cohort of patients with amnestic Alzheimer's disease (n = 20, eight female, aged 53-74 years). Neuroanatomical associations were assessed using blinded visual rating and voxel-based morphometry of patients' brain magnetic resonance images. Certain syndromic signatures were identified: pain and temperature symptoms were particularly prevalent in behavioural variant frontotemporal dementia (71% of cases) and semantic dementia (65% of cases) and in association with C9orf72 mutations (6/6 cases), but also developed in Alzheimer's disease (45% of cases) and progressive non-fluent aphasia (25% of cases). While altered temperature responsiveness was more common than altered pain responsiveness across syndromes, blunted responsiveness to pain and temperature was particularly associated with behavioural variant frontotemporal dementia (40% of symptomatic cases) and heightened responsiveness with semantic dementia (73% of symptomatic cases) and Alzheimer's disease (78% of symptomatic cases). In the voxel-based morphometry analysis of the frontotemporal lobar degeneration cohort, pain and temperature symptoms were associated with grey matter loss in a right-lateralized network including insula (P < 0.05 corrected for multiple voxel-wise comparisons within the prespecified anatomical region of interest) and anterior temporal cortex (P < 0.001 uncorrected over whole brain) previously implicated in processing homeostatic signals. Pain and temperature symptoms accompanying C9orf72 mutations were specifically associated with posterior thalamic atrophy (P < 0.05 corrected for multiple voxel-wise comparisons within the prespecified anatomical region of interest). Together the findings suggest candidate cognitive and neuroanatomical bases for these salient but under-appreciated phenotypic features of the dementias, with wider implications for the homeostatic pathophysiology and clinical management of neurodegenerative diseases.read more

TL;DR: A clinical approach to the progressive aphasias is presented, based on the experience of these disorders and directed at non-specialists, and a prospect for future progress is concluded, emphasising generic information processing deficits and novel pathophysiological biomarkers.

TL;DR: This review aims to clarify the often confusing terminology of FTD, and outline the various clinical features and diagnostic criteria of sporadic and familial FTD syndromes.

Frontotemporal lobar degeneration: Pathogenesis, pathology and pathways to phenotype
TL;DR: It is possible therefore that FTLD is a reflection of dysfunction within lysosomal/proteasomal systems resulting in failure to remove potentially neurotoxic aggregates, which ultimately overwhelm capacity to function.

Pain in amyotrophic lateral sclerosis
TL;DR: Given the multifactorial nature of pain in patients with ALS, different treatments have been suggested, ranging from non-steroidal anti-inflammatory drugs, drugs for neuropathic pain, opioids, and cannabinoids, to physical therapy strategies and preventive assistive devices.

Initial complaints in frontotemporal lobar degeneration.
TL;DR: Presenting complaints in FTLD can be misleading, and a multidisciplinary approach, including a structured behavioral interview, is important to recognize symptoms of FTLD.

TL;DR: Good replicability of the sensory testing data with comparable data variability is demonstrated, for both groups, which supports the use of these methods in studies of patients with mild to moderate AD.

Spatial and temporal functional connectivity changes between resting and attentive states
TL;DR: It is shown that moment‐to‐moment differences in connectivity at rest mirrored the variation in connectivity between tasks, and task‐dependent changes in functional connectivity of flexible regions may, therefore, be understood as shifts in the proportion of time specific connections are engaged, rather than a switch between networks per se.

The brain basis of musicophilia: evidence from frontotemporal lobar degeneration.
TL;DR: A candidate brain substrate for musicophilia is suggested as a signature of distributed network damage that may reflect a shift of hedonic processing toward more abstract (non-social) stimuli, with some specificity for particular neurodegenerative pathologies.

TL;DR: In this article, the authors collected structural magnetic resonance imaging scans and neurological examination reports of patients with brain injuries or stroke in the left or right hemisphere, but not in the postcentral gyrus as the entry site of cortical somatosensory processing.
