Serum neurofilament light and heavy chains (sNfL and sNfH) have been assessed as neuronal markers for amyotrophic lateral sclerosis (ALS) and dementias. Whereas sNfL has robust literature, systematic studies on sNfH are lacking. [...]

Background Differentiating progressive supranuclear palsy (PSP) from Parkinson disease and other parkinsonisms is challenging. MRI measures have been investigated, but most studies included small samples, limiting result reliability [...]

The NLRP3 inflammasome contributes to a wide range of conditions from infections to Alzheimer's disease. NLRP3 forms an inactive decameric cage, that upon interaction with the trans-Golgi network (TGN) and microtubule organization center (MTOC), leads to inflammasome activation, yet whether non-decamer NLRP3 species form functional inflammasomes remains unclear. [...]

Holter-ECG monitoring is a critical component of post-stroke diagnostics, guiding cardiac work-up and secondary stroke prevention. Abnormal ECG findings beyond atrial fibrillation (AF) in stroke patients remain understudied. [...]

Subjective aging predicts various developmental outcomes, including cognitive functioning. However, associations could be bidirectional. [...]

INTRODUCTIONTau species lacking truncation of the N-terminal region, including plasma N-terminal tau fragment 1 (NT1), have been previously associated with cognitive decline, neurodegeneration, and tau pathology in late-onset sporadic Alzheimer's disease (AD).METHODSHere, we examined cross-sectional and longitudinal plasma NT1 as a possible predictor of cognitive, clinical, and core AD biomarker trajectories in autosomal dominant AD (ADAD).RESULTSNT1 levels in ADAD mutation carriers (MC; n = 132) increased across the disease continuum, compared to non-carriers (NC; n = 75), becoming elevated about a decade prior to estimated symptom onset. Cross-sectional and longitudinal NT1 levels in MC were associated with clinical, cognitive, and biomarker changes. [...]

Tactile fingertip sensations are critical for everyday life. Accordingly, tactile fingertip maps have been extensively studied in human primary somatosensory cortex. [...]

The human brain stores and retrieves tactile experiences, allowing object recognition by touch, the definition of haptic preferences, and the retrieval of past bodily experiences. However, little is known about the spatial code of tactile body memories, particularly whether encoding takes place in a body-centered (tactile) reference frame, not influenced by hand posture or visual cues, or whether it takes place in an external reference frame, where tactile information is integrated with proprioceptive and visual information.

Anxiety disorders are common and impairing mental health conditions. Using data from 26,378 adults in the German National Cohort Study (NAKO), we investigated psychosocial and neuroimaging predictors of generalized anxiety disorder (GAD) symptoms and panic attacks. [...]

Aging is the gradual accumulation of structural and functional changes in an organism over time, including immune remodeling and a progressive increase in basal inflammation, or inflammaging. The mTOR pathway is a central driver of aging-related diseases, such as cancer, chronic inflammation and neurodegeneration; pharmacological inhibition with rapamycin is associated with reduced aged-related morbidity and increased lifespan across species.
